+    \class QAction
+    \brief The QAction class provides an abstract user interface
+    action that can be inserted into widgets.
+
+    \ingroup mainwindow-classes
+
+
+    \omit
+        * parent and widget are different
+        * parent does not define context
+    \endomit
+
+    In applications many common commands can be invoked via menus,
+    toolbar buttons, and keyboard shortcuts. Since the user expects
+    each command to be performed in the same way, regardless of the
+    user interface used, it is useful to represent each command as
+    an \e action.
+
+    Actions can be added to menus and toolbars, and will
+    automatically keep them in sync. For example, in a word processor,
+    if the user presses a Bold toolbar button, the Bold menu item
+    will automatically be checked.
+
+    Actions can be created as independent objects, but they may
+    also be created during the construction of menus; the QMenu class
+    contains convenience functions for creating actions suitable for
+    use as menu items.
+
+    A QAction may contain an icon, menu text, a shortcut, status text,
+    "What's This?" text, and a tooltip. Most of these can be set in
+    the constructor. They can also be set independently with
+    setIcon(), setText(), setIconText(), setShortcut(),
+    setStatusTip(), setWhatsThis(), and setToolTip(). For menu items,
+    it is possible to set an individual font with setFont().
+
+    Actions are added to widgets using QWidget::addAction() or
+    QGraphicsWidget::addAction(). Note that an action must be added to a
+    widget before it can be used; this is also true when the shortcut should
+    be global (i.e., Qt::ApplicationShortcut as Qt::ShortcutContext).
+
+    Once a QAction has been created it should be added to the relevant
+    menu and toolbar, then connected to the slot which will perform
+    the action. For example:
+
+    \snippet examples/mainwindows/application/mainwindow.cpp 19
+    \codeline
+    \snippet examples/mainwindows/application/mainwindow.cpp 28
+    \snippet examples/mainwindows/application/mainwindow.cpp 31
+
+    We recommend that actions are created as children of the window
+    they are used in. In most cases actions will be children of
+    the application's main window.
+
+    \sa QMenu, QToolBar, {Application Example}

+    \class QActionGroup
+    \brief The QActionGroup class groups actions together.
+
+    \ingroup mainwindow-classes
+
+    In some situations it is useful to group actions together. For
+    example, if you have a \gui{Left Align} action, a \gui{Right
+    Align} action, a \gui{Justify} action, and a \gui{Center} action,
+    only one of these actions should be active at any one time. One
+    simple way of achieving this is to group the actions together in
+    an action group.
+
+    Here's a example (from the \l{mainwindows/menus}{Menus} example):
+
+    \snippet examples/mainwindows/menus/mainwindow.cpp 6
+
+    Here we create a new action group. Since the action group is
+    exclusive by default, only one of the actions in the group is
+    checked at any one time.
+
+    \img qactiongroup-align.png Alignment options in a QMenu
+
+    A QActionGroup emits an triggered() signal when one of its
+    actions is chosen. Each action in an action group emits its
+    triggered() signal as usual.
+
+    As stated above, an action group is \l exclusive by default; it
+    ensures that only one checkable action is active at any one time.
+    If you want to group checkable actions without making them
+    exclusive, you can turn of exclusiveness by calling
+    setExclusive(false).
+
+    Actions can be added to an action group using addAction(), but it
+    is usually more convenient to specify a group when creating
+    actions; this ensures that actions are automatically created with
+    a parent. Actions can be visually separated from each other by
+    adding a separator action to the group; create an action and use
+    QAction's \l {QAction::}{setSeparator()} function to make it
+    considered a separator. Action groups are added to widgets with
+    the QWidget::addActions() function.
+
+    \sa QAction

+    \class QApplication
+    \brief The QApplication class manages the GUI application's control
+    flow and main settings.
+
+    QApplication contains the main event loop, where all events from the window
+    system and other sources are processed and dispatched. It also handles the
+    application's initialization, finalization, and provides session
+    management. In addition, QApplication handles most of the system-wide and
+    application-wide settings.
+
+    For any GUI application using Qt, there is precisely \bold one QApplication
+    object, no matter whether the application has 0, 1, 2 or more windows at
+    any given time. For non-GUI Qt applications, use QCoreApplication instead,
+    as it does not depend on the \l QtGui library.
+
+    The QApplication object is accessible through the instance() function that
+    returns a pointer equivalent to the global qApp pointer.
+
+    QApplication's main areas of responsibility are:
+        \list
+            \o  It initializes the application with the user's desktop settings
+                such as palette(), font() and doubleClickInterval(). It keeps
+                track of these properties in case the user changes the desktop
+                globally, for example through some kind of control panel.
+
+            \o  It performs event handling, meaning that it receives events
+                from the underlying window system and dispatches them to the
+                relevant widgets. By using sendEvent() and postEvent() you can
+                send your own events to widgets.
+
+            \o  It parses common command line arguments and sets its internal
+                state accordingly. See the \l{QApplication::QApplication()}
+                {constructor documentation} below for more details.
+
+            \o  It defines the application's look and feel, which is
+                encapsulated in a QStyle object. This can be changed at runtime
+                with setStyle().
+
+            \o  It specifies how the application is to allocate colors. See
+                setColorSpec() for details.
+
+            \o  It provides localization of strings that are visible to the
+                user via translate().
+
+            \o  It provides some magical objects like the desktop() and the
+                clipboard().
+
+            \o  It knows about the application's windows. You can ask which
+                widget is at a certain position using widgetAt(), get a list of
+                topLevelWidgets() and closeAllWindows(), etc.
+
+            \o  It manages the application's mouse cursor handling, see
+                setOverrideCursor()
+
+            \o  On the X window system, it provides functions to flush and sync
+                the communication stream, see flushX() and syncX().
+
+            \o  It provides support for sophisticated \l{Session Management}
+                {session management}. This makes it possible for applications
+                to terminate gracefully when the user logs out, to cancel a
+                shutdown process if termination isn't possible and even to
+                preserve the entire application's state for a future session.
+                See isSessionRestored(), sessionId() and commitData() and
+                saveState() for details.
+        \endlist
+
+    Since the QApplication object does so much initialization, it \e{must} be
+    created before any other objects related to the user interface are created.
+    QApplication also deals with common command line arguments. Hence, it is
+    usually a good idea to create it \e before any interpretation or
+    modification of \c argv is done in the application itself.

+
+    Qt debugging options (not available if Qt was compiled without the QT_DEBUG
+    flag defined):
+    \list
+        \o  -nograb, tells Qt that it must never grab the mouse or the
+            keyboard.
+        \o  -dograb (only under X11), running under a debugger can cause an
+            implicit -nograb, use -dograb to override.
+        \o  -sync (only under X11), switches to synchronous mode for
+            debugging.
+    \endlist
+
+    See \l{Debugging Techniques} for a more detailed explanation.
+
+    All Qt programs automatically support the following command line options:
+    \list
+        \o  -style= \e style, sets the application GUI style. Possible values
+            are \c motif, \c windows, and \c platinum. If you compiled Qt with
+            additional styles or have additional styles as plugins these will
+            be available to the \c -style command line option.
+        \o  -style \e style, is the same as listed above.
+        \o  -stylesheet= \e stylesheet, sets the application \l styleSheet. The
+            value must be a path to a file that contains the Style Sheet.
+            \note Relative URLs in the Style Sheet file are relative to the
+            Style Sheet file's path.
+        \o  -stylesheet \e stylesheet, is the same as listed above.
+        \o  -session= \e session, restores the application from an earlier
+            \l{Session Management}{session}.
+        \o  -session \e session, is the same as listed above.
+        \o  -widgetcount, prints debug message at the end about number of
+            widgets left undestroyed and maximum number of widgets existed at
+            the same time
+        \o  -reverse, sets the application's layout direction to
+            Qt::RightToLeft
+        \o  -graphicssystem, sets the backend to be used for on-screen widgets
+            and QPixmaps. Available options are \c{raster} and \c{opengl}.
+        \o  -qmljsdebugger=, activates the QML/JS debugger with a specified port.
+            The value must be of format port:1234[,block], where block is optional
+            and will make the application wait until a debugger connects to it.
+    \endlist
+
+    The X11 version of Qt supports some traditional X11 command line options:
+    \list
+        \o  -display \e display, sets the X display (default is $DISPLAY).
+        \o  -geometry \e geometry, sets the client geometry of the first window
+            that is shown.
+        \o  -fn or \c -font \e font, defines the application font. The font
+            should be specified using an X logical font description. Note that
+            this option is ignored when Qt is built with fontconfig support enabled.
+        \o  -bg or \c -background \e color, sets the default background color
+            and an application palette (light and dark shades are calculated).
+        \o  -fg or \c -foreground \e color, sets the default foreground color.
+        \o  -btn or \c -button \e color, sets the default button color.
+        \o  -name \e name, sets the application name.
+        \o  -title \e title, sets the application title.
+        \o  -visual \c TrueColor, forces the application to use a TrueColor
+            visual on an 8-bit display.
+        \o  -ncols \e count, limits the number of colors allocated in the color
+            cube on an 8-bit display, if the application is using the
+            QApplication::ManyColor color specification. If \e count is 216
+            then a 6x6x6 color cube is used (i.e. 6 levels of red, 6 of green,
+            and 6 of blue); for other values, a cube approximately proportional
+            to a 2x3x1 cube is used.
+        \o  -cmap, causes the application to install a private color map on an
+            8-bit display.
+        \o  -im, sets the input method server (equivalent to setting the
+            XMODIFIERS environment variable)
+        \o  -inputstyle, defines how the input is inserted into the given
+            widget, e.g., \c onTheSpot makes the input appear directly in the
+            widget, while \c overTheSpot makes the input appear in a box
+            floating over the widget and is not inserted until the editing is
+            done.
+    \endlist
+
+    \section1 X11 Notes
+
+    If QApplication fails to open the X11 display, it will terminate
+    the process. This behavior is consistent with most X11
+    applications.

+
+    The color specification controls how the application allocates colors when
+    run on a display with a limited amount of colors, e.g. 8 bit / 256 color
+    displays.
+
+    The color specification must be set before you create the QApplication
+    object.
+
+    The options are:
+    \list
+        \o  QApplication::NormalColor. This is the default color allocation
+            strategy. Use this option if your application uses buttons, menus,
+            texts and pixmaps with few colors. With this option, the
+            application uses system global colors. This works fine for most
+            applications under X11, but on the Windows platform, it may cause
+            dithering of non-standard colors.
+        \o  QApplication::CustomColor. Use this option if your application
+            needs a small number of custom colors. On X11, this option is the
+            same as NormalColor. On Windows, Qt creates a Windows palette, and
+            allocates colors to it on demand.
+        \o  QApplication::ManyColor. Use this option if your application is
+            very color hungry, e.g., it requires thousands of colors. \br
+            Under X11 the effect is:
+            \list
+                \o  For 256-color displays which have at best a 256 color true
+                    color visual, the default visual is used, and colors are
+                    allocated from a color cube. The color cube is the 6x6x6
+                    (216 color) "Web palette" (the red, green, and blue
+                    components always have one of the following values: 0x00,
+                    0x33, 0x66, 0x99, 0xCC, or 0xFF), but the number of colors
+                    can be changed by the \e -ncols option. The user can force
+                    the application to use the true color visual with the
+                    \l{QApplication::QApplication()}{-visual} option.
+                \o  For 256-color displays which have a true color visual with
+                    more than 256 colors, use that visual. Silicon Graphics X
+                    servers this feature, for example. They provide an 8 bit
+                    visual by default but can deliver true color when asked.
+            \endlist
+            On Windows, Qt creates a Windows palette, and fills it with a color
+            cube.

+    \class QSessionManager
+    \brief The QSessionManager class provides access to the session manager.
+
+    A session manager in a desktop environment (in which Qt GUI applications
+    live) keeps track of a session, which is a group of running applications,
+    each of which has a particular state. The state of an application contains
+    (most notably) the documents the application has open and the position and
+    size of its windows.
+
+    The session manager is used to save the session, e.g., when the machine is
+    shut down, and to restore a session, e.g., when the machine is started up.
+    We recommend that you use QSettings to save an application's settings,
+    for example, window positions, recently used files, etc. When the
+    application is restarted by the session manager, you can restore the
+    settings.
+
+    QSessionManager provides an interface between the application and the
+    session manager so that the program can work well with the session manager.
+    In Qt, session management requests for action are handled by the two
+    virtual functions QApplication::commitData() and QApplication::saveState().
+    Both provide a reference to a session manager object as argument, to allow
+    the application to communicate with the session manager. The session
+    manager can only be accessed through these functions.
+
+    No user interaction is possible \e unless the application gets explicit
+    permission from the session manager. You ask for permission by calling
+    allowsInteraction() or, if it is really urgent, allowsErrorInteraction().
+    Qt does not enforce this, but the session manager may.
+
+    You can try to abort the shutdown process by calling cancel(). The default
+    commitData() function does this if some top-level window rejected its
+    closeEvent().
+
+    For sophisticated session managers provided on Unix/X11, QSessionManager
+    offers further possibilities to fine-tune an application's session
+    management behavior: setRestartCommand(), setDiscardCommand(),
+    setRestartHint(), setProperty(), requestPhase2(). See the respective
+    function descriptions for further details.

+/*! \enum QSessionManager::RestartHint
+
+    This enum type defines the circumstances under which this application wants
+    to be restarted by the session manager. The current values are:
+
+    \value  RestartIfRunning    If the application is still running when the
+                                session is shut down, it wants to be restarted
+                                at the start of the next session.
+
+    \value  RestartAnyway       The application wants to be started at the
+                                start of the next session, no matter what.
+                                (This is useful for utilities that run just
+                                after startup and then quit.)
+
+    \value  RestartImmediately  The application wants to be started immediately
+                                whenever it is not running.
+
+    \value  RestartNever        The application does not want to be restarted
+                                automatically.

+
+    The rationale behind this mechanism is to make it possible to synchronize
+    user interaction during a shutdown. Advanced session managers may ask all
+    applications simultaneously to commit their data, resulting in a much
+    faster shutdown.
+
+    When the interaction is completed we strongly recommend releasing the user
+    interaction semaphore with a call to release(). This way, other
+    applications may get the chance to interact with the user while your
+    application is still busy saving data. (The semaphore is implicitly
+    released when the application exits.)
+
+    If the user decides to cancel the shutdown process during the interaction
+    phase, you must tell the session manager that this has happened by calling
+    cancel().
+
+    Here's an example of how an application's QApplication::commitData() might

+    \class QBoxLayout
+
+    \brief The QBoxLayout class lines up child widgets horizontally or
+    vertically.
+
+    \ingroup geomanagement
+
+    QBoxLayout takes the space it gets (from its parent layout or from
+    the parentWidget()), divides it up into a row of boxes, and makes
+    each managed widget fill one box.
+
+    \image qhboxlayout-with-5-children.png Horizontal box layout with five child widgets
+
+    If the QBoxLayout's orientation is Qt::Horizontal the boxes are
+    placed in a row, with suitable sizes. Each widget (or other box)
+    will get at least its minimum size and at most its maximum size.
+    Any excess space is shared according to the stretch factors (more
+    about that below).
+
+    \image qvboxlayout-with-5-children.png Vertical box layout with five child widgets
+
+    If the QBoxLayout's orientation is Qt::Vertical, the boxes are
+    placed in a column, again with suitable sizes.
+
+    The easiest way to create a QBoxLayout is to use one of the
+    convenience classes, e.g. QHBoxLayout (for Qt::Horizontal boxes)
+    or QVBoxLayout (for Qt::Vertical boxes). You can also use the
+    QBoxLayout constructor directly, specifying its direction as
+    LeftToRight, RightToLeft, TopToBottom, or BottomToTop.
+
+    If the QBoxLayout is not the top-level layout (i.e. it is not
+    managing all of the widget's area and children), you must add it
+    to its parent layout before you can do anything with it. The
+    normal way to add a layout is by calling
+    parentLayout-\>addLayout().
+
+    Once you have done this, you can add boxes to the QBoxLayout using
+    one of four functions:
+
+    \list
+    \o addWidget() to add a widget to the QBoxLayout and set the
+    widget's stretch factor. (The stretch factor is along the row of
+    boxes.)
+
+    \o addSpacing() to create an empty box; this is one of the
+    functions you use to create nice and spacious dialogs. See below
+    for ways to set margins.
+
+    \o addStretch() to create an empty, stretchable box.
+
+    \o addLayout() to add a box containing another QLayout to the row
+    and set that layout's stretch factor.
+    \endlist
+
+    Use insertWidget(), insertSpacing(), insertStretch() or
+    insertLayout() to insert a box at a specified position in the
+    layout.
+
+    QBoxLayout also includes two margin widths:
+
+    \list
+    \o setContentsMargins() sets the width of the outer border on 
+       each side of the widget. This is the width of the reserved space 
+       along each of the QBoxLayout's four sides.
+    \o setSpacing() sets the width between neighboring boxes. (You
+       can use addSpacing() to get more space at a particular spot.)
+    \endlist
+
+    The margin default is provided by the style. The default margin
+    most Qt styles specify is 9 for child widgets and 11 for windows.
+    The spacing defaults to the same as the margin width for a
+    top-level layout, or to the same as the parent layout.
+
+    To remove a widget from a layout, call removeWidget(). Calling
+    QWidget::hide() on a widget also effectively removes the widget
+    from the layout until QWidget::show() is called.
+
+    You will almost always want to use QVBoxLayout and QHBoxLayout
+    rather than QBoxLayout because of their convenient constructors.

+/*!
+    \class QClipboard
+    \brief The QClipboard class provides access to the window system clipboard.
+
+    The clipboard offers a simple mechanism to copy and paste data
+    between applications.
+
+    QClipboard supports the same data types that QDrag does, and uses
+    similar mechanisms. For advanced clipboard usage read \l{Drag and
+    Drop}.
+
+    There is a single QClipboard object in an application, accessible
+    as QApplication::clipboard().
+
+    Example:
+    \snippet doc/src/snippets/code/src_gui_kernel_qclipboard.cpp 0
+
+    QClipboard features some convenience functions to access common
+    data types: setText() allows the exchange of Unicode text and
+    setPixmap() and setImage() allows the exchange of QPixmaps and
+    QImages between applications. The setMimeData() function is the
+    ultimate in flexibility: it allows you to add any QMimeData into
+    the clipboard. There are corresponding getters for each of these,
+    e.g. text(), image() and pixmap(). You can clear the clipboard by
+    calling clear().
+
+    A typical example of the use of these functions follows:
+
+    \snippet doc/src/snippets/droparea.cpp 0
+
+    \section1 Notes for X11 Users
+
+    \list
+
+    \i The X11 Window System has the concept of a separate selection
+    and clipboard.  When text is selected, it is immediately available
+    as the global mouse selection.  The global mouse selection may
+    later be copied to the clipboard.  By convention, the middle mouse
+    button is used to paste the global mouse selection.
+
+    \i X11 also has the concept of ownership; if you change the
+    selection within a window, X11 will only notify the owner and the
+    previous owner of the change, i.e. it will not notify all
+    applications that the selection or clipboard data changed.
+
+    \i Lastly, the X11 clipboard is event driven, i.e. the clipboard
+    will not function properly if the event loop is not running.
+    Similarly, it is recommended that the contents of the clipboard
+    are stored or retrieved in direct response to user-input events,
+    e.g. mouse button or key presses and releases.  You should not
+    store or retrieve the clipboard contents in response to timer or
+    non-user-input events.
+
+    \i Since there is no standard way to copy and paste files between
+    applications on X11, various MIME types and conventions are currently
+    in use. For instance, Nautilus expects files to be supplied with a
+    \c{x-special/gnome-copied-files} MIME type with data beginning with
+    the cut/copy action, a newline character, and the URL of the file.
+
+    \endlist
+
+    \section1 Notes for Mac OS X Users
+
+    Mac OS X supports a separate find buffer that holds the current
+    search string in Find operations. This find clipboard can be accessed
+    by specifying the FindBuffer mode.
+
+    \section1 Notes for Windows and Mac OS X Users
+
+    \list
+
+    \i Windows and Mac OS X do not support the global mouse
+    selection; they only supports the global clipboard, i.e. they
+    only add text to the clipboard when an explicit copy or cut is
+    made.
+
+    \i Windows and Mac OS X does not have the concept of ownership;
+    the clipboard is a fully global resource so all applications are
+    notified of changes.

+ qcocoapanel_mac.mm to avoid manually doing copy and paste of the exact
+ same code needed at both places. This solution makes it more difficult
+ to e.g fix a bug in qcocoawindow_mac.mm, but forget to do the same in
+ qcocoapanel_mac.mm.
+ The reason we need to do copy and paste in the first place, rather than
+ resolve to method overriding, is that QCocoaPanel needs to inherit from
+ NSPanel, while QCocoaWindow needs to inherit NSWindow rather than NSPanel).

+// in the title bar. This is to support unifiedToolbar look.
+
+// This method is very special. To begin with, it is a
+// method that will get called only if we enable documentMode.
+// Furthermore, it won't get called as a normal method, we swap
+// this method with the normal implementation of drawRect in
+// _NSThemeFrame. When this method is active, its mission is to
+// first call the original drawRect implementation so the widget
+// gets proper painting. After that, it needs to detect if there
+// is a toolbar or not, in order to decide how to handle the unified
+// look. The distinction is important since the presence and
+// visibility of a toolbar change the way we enter into unified mode.
+// When there is a toolbar and that toolbar is visible, the problem
+// is as simple as to tell the toolbar not to draw its baseline.
+// However when there is not toolbar or the toolbar is not visible,
+// we need to draw a line on top of the baseline, because the baseline
+// in that case will belong to the title. For this case we need to draw
+// a line on top of the baseline.
+// As usual, there is a special case. When we first are called, we might
+// need to repaint ourselves one more time. We only need that if we
+// didn't get the activation, i.e. when we are launched via the command
+// line. And this only if the toolbar is visible from the beginning,
+// so we have a special flag that signals if we need to repaint or not.

+    \class QCursor
+
+    \brief The QCursor class provides a mouse cursor with an arbitrary
+    shape.
+
+    \ingroup appearance
+    \ingroup shared
+
+
+    This class is mainly used to create mouse cursors that are
+    associated with particular widgets and to get and set the position
+    of the mouse cursor.
+
+    Qt has a number of standard cursor shapes, but you can also make
+    custom cursor shapes based on a QBitmap, a mask and a hotspot.
+
+    To associate a cursor with a widget, use QWidget::setCursor(). To
+    associate a cursor with all widgets (normally for a short period
+    of time), use QApplication::setOverrideCursor().
+
+    To set a cursor shape use QCursor::setShape() or use the QCursor
+    constructor which takes the shape as argument, or you can use one
+    of the predefined cursors defined in the \l Qt::CursorShape enum.
+
+    If you want to create a cursor with your own bitmap, either use
+    the QCursor constructor which takes a bitmap and a mask or the
+    constructor which takes a pixmap as arguments.
+
+    To set or get the position of the mouse cursor use the static
+    methods QCursor::pos() and QCursor::setPos().
+
+    \bold{Note:} It is possible to create a QCursor before
+    QApplication, but it is not useful except as a place-holder for a
+    real QCursor created after QApplication. Attempting to use a
+    QCursor that was created before QApplication will result in a
+    crash.
+
+    \section1 A Note for X11 Users
+
+    On X11, Qt supports the \link
+    http://www.xfree86.org/4.3.0/Xcursor.3.html Xcursor\endlink
+    library, which allows for full color icon themes. The table below
+    shows the cursor name used for each Qt::CursorShape value. If a
+    cursor cannot be found using the name shown below, a standard X11
+    cursor will be used instead. Note: X11 does not provide
+    appropriate cursors for all possible Qt::CursorShape values. It
+    is possible that some cursors will be taken from the Xcursor
+    theme, while others will use an internal bitmap cursor.

+    \class QDesktopWidget
+    \brief The QDesktopWidget class provides access to screen information on multi-head systems.
+
+    \ingroup advanced
+    \ingroup desktop
+
+    Systems with more than one graphics card and monitor can manage the
+    physical screen space available either as multiple desktops, or as a
+    large virtual desktop.
+
+    This class provides information about the user's desktop, such as its
+    total size, number of screens, the geometry of each screen, and whether
+    they are configured as separate desktops or a single virtual desktop.
+
+    Widgets provided by Qt use this class to place tooltips, menus and
+    dialog boxes on the correct screen for their parent or application
+    widgets. Applications can use this class to obtain information that
+    can be used to save window positions, or to place child widgets and
+    dialogs on one particular screen.
+
+    \section1 Obtaining a Desktop Widget
+
+    The QApplication::desktop() function is used to get an instance of
+    QDesktopWidget.
+
+    The widget's screenGeometry() function provides information about the
+    geometry of the available screens with. The number of screens
+    available is returned by screenCount, and the screenCountChanged()
+    signal is emitted when screens are added or removed.
+    The screen number that a particular point or widget is located in
+    is returned by screenNumber().
+
+    \section1 Screen Geometry
+
+    To obtain the dimensions of a particular screen, call the screenGeometry()
+    function. On some desktop environments, not all of the screen is
+    available for applications to use; for example, an application dock or
+    menu bar may take up some space. Use the availableGeometry() function
+    to obtain the available area for applications.
+
+    QDesktopWidget also inherits the QWidget properties, width() and
+    height(), which specify the size of the desktop. However, for
+    desktops with multiple screens, the size of the desktop is the union
+    of all the screen sizes, so width() and height() should \e not be
+    used for computing the size of a widget to be placed on one of the
+    screens.
+
+    On systems that are configured to use the available screens as a
+    single, large virtual desktop, the virtualDesktop property will be
+    set to true. In this case, the widget's size is usually the size of
+    the bounding rectangle of all the screens.
+
+    \section1 Use of the Primary Screen
+
+    For an application, the screen where the main widget resides is the
+    primary screen. This is stored in the primaryScreen property.
+    All windows opened in the context of the application should be
+    constrained to the boundaries of the primary screen; for example,
+    it would be inconvenient if a dialog box popped up on a different
+    screen, or split over two screens.
+
+    \image qdesktopwidget.png Managing Multiple Screens
+
+    In the illustration above, Application One's primary screen is
+    screen 0, and App Two's primary screen is screen 1.
+
+    \sa QApplication, QApplication::desktop(), QX11Info::appRootWindow()

+    \class QDrag
+    \brief The QDrag class provides support for MIME-based drag and drop data
+    transfer.
+
+    Drag and drop is an intuitive way for users to copy or move data around in an
+    application, and is used in many desktop environments as a mechanism for copying
+    data between applications. Drag and drop support in Qt is centered around the
+    QDrag class that handles most of the details of a drag and drop operation.
+
+    The data to be transferred by the drag and drop operation is contained in a
+    QMimeData object. This is specified with the setMimeData() function in the
+    following way:
+
+    \snippet doc/src/snippets/dragging/mainwindow.cpp 1
+
+    Note that setMimeData() assigns ownership of the QMimeData object to the
+    QDrag object. The QDrag must be constructed on the heap with a parent QWidget
+    to ensure that Qt can clean up after the drag and drop operation has been
+    completed.
+
+    A pixmap can be used to represent the data while the drag is in
+    progress, and will move with the cursor to the drop target. This
+    pixmap typically shows an icon that represents the MIME type of
+    the data being transferred, but any pixmap can be set with
+    setPixmap(). The cursor's hot spot can be given a position
+    relative to the top-left corner of the pixmap with the
+    setHotSpot() function. The following code positions the pixmap so
+    that the cursor's hot spot points to the center of its bottom
+    edge:
+
+    \snippet doc/src/snippets/separations/finalwidget.cpp 2
+
+    \note On X11, the pixmap may not be able to keep up with the mouse
+    movements if the hot spot causes the pixmap to be displayed
+    directly under the cursor.
+
+    The source and target widgets can be found with source() and target().
+    These functions are often used to determine whether drag and drop operations
+    started and finished at the same widget, so that special behavior can be
+    implemented.
+
+    QDrag only deals with the drag and drop operation itself. It is up to the
+    developer to decide when a drag operation begins, and how a QDrag object should
+    be constructed and used. For a given widget, it is often necessary to
+    reimplement \l{QWidget::mousePressEvent()}{mousePressEvent()} to determine
+    whether the user has pressed a mouse button, and reimplement
+    \l{QWidget::mouseMoveEvent()}{mouseMoveEvent()} to check whether a QDrag is
+    required.
+

+    \ingroup events
+
+    \brief The QMouseEvent class contains parameters that describe a mouse event.
+
+    Mouse events occur when a mouse button is pressed or released
+    inside a widget, or when the mouse cursor is moved.
+
+    Mouse move events will occur only when a mouse button is pressed
+    down, unless mouse tracking has been enabled with
+    QWidget::setMouseTracking().
+
+    Qt automatically grabs the mouse when a mouse button is pressed
+    inside a widget; the widget will continue to receive mouse events
+    until the last mouse button is released.
+
+    A mouse event contains a special accept flag that indicates
+    whether the receiver wants the event. You should call ignore() if
+    the mouse event is not handled by your widget. A mouse event is
+    propagated up the parent widget chain until a widget accepts it
+    with accept(), or an event filter consumes it.
+
+    \note If a mouse event is propagated to a \l{QWidget}{widget} for
+    which Qt::WA_NoMousePropagation has been set, that mouse event
+    will not be propagated further up the parent widget chain.
+
+    The state of the keyboard modifier keys can be found by calling the
+    \l{QInputEvent::modifiers()}{modifiers()} function, inherited from
+    QInputEvent.
+
+    The functions pos(), x(), and y() give the cursor position
+    relative to the widget that receives the mouse event. If you
+    move the widget as a result of the mouse event, use the global
+    position returned by globalPos() to avoid a shaking motion.
+
+    The QWidget::setEnabled() function can be used to enable or
+    disable mouse and keyboard events for a widget.
+
+    Reimplement the QWidget event handlers, QWidget::mousePressEvent(),
+    QWidget::mouseReleaseEvent(), QWidget::mouseDoubleClickEvent(),
+    and QWidget::mouseMoveEvent() to receive mouse events in your own
+    widgets.

+    QEvent::HoverMove is also slightly different from QEvent::MouseMove. Let us
+    consider a top-level window A containing a child B which in turn contains a

+
+    Key events are sent to the widget with keyboard input focus
+    when keys are pressed or released.
+
+    A key event contains a special accept flag that indicates whether
+    the receiver will handle the key event. You should call ignore()
+    if the key press or release event is not handled by your widget.
+    A key event is propagated up the parent widget chain until a

+    Key events for multimedia keys are ignored by default. You should
+    call accept() if your widget handles those events.
+
+    The QWidget::setEnable() function can be used to enable or disable
+    mouse and keyboard events for a widget.

+    usually by choosing "Close" from the window menu, or by clicking
+    the \gui{X} title bar button. They are also sent when you call
+    QWidget::close() to close a widget programmatically.
+
+    Close events contain a flag that indicates whether the receiver
+    wants the widget to be closed or not. When a widget accepts the
+    close event, it is hidden (and destroyed if it was created with
+    the Qt::WA_DeleteOnClose flag). If it refuses to accept the close
+    event nothing happens. (Under X11 it is possible that the window
+    manager will forcibly close the window; but at the time of writing
+    we are not aware of any window manager that does this.)
+
+    The event handler QWidget::closeEvent() receives close events. The
+    default implementation of this event handler accepts the close
+    event. If you do not want your widget to be hidden, or want some
+    special handing, you should reimplement the event handler and
+    ignore() the event.
+
+    The \l{mainwindows/application#close event handler}{closeEvent() in the
+    Application example} shows a close event handler that
+    asks whether to save a document before closing.
+
+    If you want the widget to be deleted when it is closed, create it
+    with the Qt::WA_DeleteOnClose flag. This is very useful for

+    \class QInputMethodEvent
+    \brief The QInputMethodEvent class provides parameters for input method events.
+
+    \ingroup events
+
+    Input method events are sent to widgets when an input method is
+    used to enter text into a widget. Input methods are widely used
+    to enter text for languages with non-Latin alphabets.
+
+    Note that when creating custom text editing widgets, the
+    Qt::WA_InputMethodEnabled window attribute must be set explicitly
+    (using the QWidget::setAttribute() function) in order to receive
+    input method events.
+
+    The events are of interest to authors of keyboard entry widgets
+    who want to be able to correctly handle languages with complex
+    character input. Text input in such languages is usually a three
+    step process:
+
+    \list 1
+    \o \bold{Starting to Compose}
+
+       When the user presses the first key on a keyboard, an input
+       context is created. This input context will contain a string
+       of the typed characters.
+
+    \o \bold{Composing}
+
+       With every new key pressed, the input method will try to create a
+       matching string for the text typed so far called preedit
+       string. While the input context is active, the user can only move
+       the cursor inside the string belonging to this input context.
+
+    \o \bold{Completing}
+
+       At some point, the user will activate a user interface component
+       (perhaps using a particular key) where they can choose from a
+       number of strings matching the text they have typed so far. The
+       user can either confirm their choice cancel the input; in either
+       case the input context will be closed.
+    \endlist
+
+    QInputMethodEvent models these three stages, and transfers the
+    information needed to correctly render the intermediate result. A
+    QInputMethodEvent has two main parameters: preeditString() and
+    commitString(). The preeditString() parameter gives the currently
+    active preedit string. The commitString() parameter gives a text
+    that should get added to (or replace parts of) the text of the
+    editor widget. It usually is a result of the input operations and
+    has to be inserted to the widgets text directly before the preedit
+    string.
+
+    If the commitString() should replace parts of the of the text in
+    the editor, replacementLength() will contain the number of
+    characters to be replaced. replacementStart() contains the position
+    at which characters are to be replaced relative from the start of
+    the preedit string.
+
+    A number of attributes control the visual appearance of the
+    preedit string (the visual appearance of text outside the preedit
+    string is controlled by the widget only). The AttributeType enum
+    describes the different attributes that can be set.
+
+    A class implementing QWidget::inputMethodEvent() or
+    QGraphicsItem::inputMethodEvent() should at least understand and
+    honor the \l TextFormat and \l Cursor attributes.
+
+    Since input methods need to be able to query certain properties
+    from the widget or graphics item, subclasses must also implement
+    QWidget::inputMethodQuery() and QGraphicsItem::inputMethodQuery(),
+    respectively.
+
+    When receiving an input method event, the text widget has to performs the
+    following steps:
+
+    \list 1
+    \o If the widget has selected text, the selected text should get
+       removed.
+
+    \o Remove the text starting at replacementStart() with length
+       replacementLength() and replace it by the commitString(). If
+       replacementLength() is 0, replacementStart() gives the insertion
+       position for the commitString().
+
+       When doing replacement the area of the preedit
+       string is ignored, thus a replacement starting at -1 with a length
+       of 2 will remove the last character before the preedit string and
+       the first character afterwards, and insert the commit string
+       directly before the preedit string.
+
+       If the widget implements undo/redo, this operation gets added to
+       the undo stack.
+
+    \o If there is no current preedit string, insert the
+       preeditString() at the current cursor position; otherwise replace
+       the previous preeditString with the one received from this event.
+
+       If the widget implements undo/redo, the preeditString() should not
+       influence the undo/redo stack in any way.
+
+       The widget should examine the list of attributes to apply to the
+       preedit string. It has to understand at least the TextFormat and
+       Cursor attributes and render them as specified.

+
+    Tablet Events are generated from a Wacom tablet. Most of the time you will
+    want to deal with events from the tablet as if they were events from a
+    mouse; for example, you would retrieve the cursor position with x(), y(),
+    pos(), globalX(), globalY(), and globalPos(). In some situations you may
+    wish to retrieve the extra information provided by the tablet device
+    driver; for example, you might want to do subpixeling with higher
+    resolution coordinates or you may want to adjust color brightness based on
+    pressure.  QTabletEvent allows you to read the pressure(), the xTilt(), and
+    yTilt(), as well as the type of device being used with device() (see
+    \l{TabletDevice}). It can also give you the minimum and maximum values for
+    each device's pressure and high resolution coordinates.
+
+    A tablet event contains a special accept flag that indicates whether the
+    receiver wants the event. You should call QTabletEvent::accept() if you
+    handle the tablet event; otherwise it will be sent to the parent widget.
+    The exception are TabletEnterProximity and TabletLeaveProximity events,
+    these are only sent to QApplication and don't check whether or not they are

+    The QWidget::setEnabled() function can be used to enable or

+
+    \brief The QDropEvent class provides an event which is sent when a
+    drag and drop action is completed.
+
+    When a widget \l{QWidget::setAcceptDrops()}{accepts drop events}, it will
+    receive this event if it has accepted the most recent QDragEnterEvent or
+    QDragMoveEvent sent to it.
+
+    The drop event contains a proposed action, available from proposedAction(), for
+    the widget to either accept or ignore. If the action can be handled by the
+    widget, you should call the acceptProposedAction() function. Since the
+    proposed action can be a combination of \l Qt::DropAction values, it may be
+    useful to either select one of these values as a default action or ask
+    the user to select their preferred action.
+
+    If the proposed drop action is not suitable, perhaps because your custom
+    widget does not support that action, you can replace it with any of the
+    \l{possibleActions()}{possible drop actions} by calling setDropAction()
+    with your preferred action. If you set a value that is not present in the
+    bitwise OR combination of values returned by possibleActions(), the default
+    copy action will be used. Once a replacement drop action has been set, call
+    accept() instead of acceptProposedAction() to complete the drop operation.
+
+    The mimeData() function provides the data dropped on the widget in a QMimeData
+    object. This contains information about the MIME type of the data in addition to
+    the data itself.

+
+    \section1 Enabling Touch Events
+
+    Touch events occur when pressing, releasing, or moving one or more touch points on a touch
+    device (such as a touch-screen or track-pad). To receive touch events, widgets have to have the
+    Qt::WA_AcceptTouchEvents attribute set and graphics items need to have the
+    \l{QGraphicsItem::setAcceptTouchEvents()}{acceptTouchEvents} attribute set to true.
+
+    When using QAbstractScrollArea based widgets, you should enable the Qt::WA_AcceptTouchEvents
+    attribute on the scroll area's \l{QAbstractScrollArea::viewport()}{viewport}.
+
+    Similarly to QMouseEvent, Qt automatically grabs each touch point on the first press inside a
+    widget, and the widget will receive all updates for the touch point until it is released.
+    Note that it is possible for a widget to receive events for numerous touch points, and that
+    multiple widgets may be receiving touch events at the same time.
+
+    \section1 Event Handling
+
+    All touch events are of type QEvent::TouchBegin, QEvent::TouchUpdate, or QEvent::TouchEnd.
+    Reimplement QWidget::event() or QAbstractScrollArea::viewportEvent() for widgets and
+    QGraphicsItem::sceneEvent() for items in a graphics view to receive touch events.
+
+    The QEvent::TouchUpdate and QEvent::TouchEnd events are sent to the widget or item that
+    accepted the QEvent::TouchBegin event. If the QEvent::TouchBegin event is not accepted and not
+    filtered by an event filter, then no further touch events are sent until the next
+    QEvent::TouchBegin.
+
+    The touchPoints() function returns a list of all touch points contained in the event.
+    Information about each touch point can be retrieved using the QTouchEvent::TouchPoint class.
+    The Qt::TouchPointState enum describes the different states that a touch point may have.
+
+    \section1 Event Delivery and Propagation
+
+    By default, QWidget::event() translates the first non-primary touch point in a QTouchEvent into
+    a QMouseEvent. This makes it possible to enable touch events on existing widgets that do not
+    normally handle QTouchEvent. See below for information on some special considerations needed
+    when doing this.
+
+    QEvent::TouchBegin is the first touch event sent to a widget. The QEvent::TouchBegin event
+    contains a special accept flag that indicates whether the receiver wants the event. By default,
+    the event is accepted. You should call ignore() if the touch event is not handled by your
+    widget. The QEvent::TouchBegin event is propagated up the parent widget chain until a widget
+    accepts it with accept(), or an event filter consumes it. For QGraphicsItems, the
+    QEvent::TouchBegin event is propagated to items under the mouse (similar to mouse event
+    propagation for QGraphicsItems).
+
+    \section1 Touch Point Grouping
+
+    As mentioned above, it is possible that several widgets can be receiving QTouchEvents at the
+    same time. However, Qt makes sure to never send duplicate QEvent::TouchBegin events to the same
+    widget, which could theoretically happen during propagation if, for example, the user touched 2
+    separate widgets in a QGroupBox and both widgets ignored the QEvent::TouchBegin event.
+
+    To avoid this, Qt will group new touch points together using the following rules:
+
+    \list
+
+    \i When the first touch point is detected, the destination widget is determined firstly by the
+    location on screen and secondly by the propagation rules.
+
+    \i When additional touch points are detected, Qt first looks to see if there are any active
+    touch points on any ancestor or descendent of the widget under the new touch point. If there
+    are, the new touch point is grouped with the first, and the new touch point will be sent in a
+    single QTouchEvent to the widget that handled the first touch point. (The widget under the new
+    touch point will not receive an event).
+
+    \endlist
+
+    This makes it possible for sibling widgets to handle touch events independently while making
+    sure that the sequence of QTouchEvents is always correct.
+
+    \section1 Mouse Events and the Primary Touch Point
+
+    QTouchEvent delivery is independent from that of QMouseEvent. On some windowing systems, mouse
+    events are also sent for the \l{QTouchEvent::TouchPoint::isPrimary()}{primary touch point}.
+    This means it is possible for your widget to receive both QTouchEvent and QMouseEvent for the
+    same user interaction point. You can use the QTouchEvent::TouchPoint::isPrimary() function to
+    identify the primary touch point.
+
+    Note that on some systems, it is possible to receive touch events without a primary touch
+    point. All this means is that there will be no mouse event generated for the touch points in
+    the QTouchEvent.
+
+    \section1 Caveats
+
+    \list
+
+    \i As mentioned above, enabling touch events means multiple widgets can be receiving touch
+    events simultaneously. Combined with the default QWidget::event() handling for QTouchEvents,
+    this gives you great flexibility in designing touch user interfaces. Be aware of the
+    implications. For example, it is possible that the user is moving a QSlider with one finger and
+    pressing a QPushButton with another. The signals emitted by these widgets will be
+    interleaved.
+
+    \i Recursion into the event loop using one of the exec() methods (e.g., QDialog::exec() or
+    QMenu::exec()) in a QTouchEvent event handler is not supported. Since there are multiple event
+    recipients, recursion may cause problems, including but not limited to lost events
+    and unexpected infinite recursion.
+
+    \i QTouchEvents are not affected by a \l{QWidget::grabMouse()}{mouse grab} or an
+    \l{QApplication::activePopupWidget()}{active pop-up widget}. The behavior of QTouchEvents is
+    undefined when opening a pop-up or grabbing the mouse while there are more than one active touch
+    points.

+
+    \brief The QGestureEvent class provides the description of triggered gestures.
+
+    The QGestureEvent class contains a list of gestures, which can be obtained using the
+    gestures() function.
+
+    The gestures are either active or canceled. A list of those that are currently being
+    executed can be obtained using the activeGestures() function. A list of those which
+    were previously active and have been canceled can be accessed using the
+    canceledGestures() function. A gesture might be canceled if the current window loses
+    focus, for example, or because of a timeout, or for other reasons.
+
+    If the event handler does not accept the event by calling the generic
+    QEvent::accept() function, all individual QGesture object that were not
+    accepted and in the Qt::GestureStarted state will be propagated up the
+    parent widget chain until a widget accepts them individually, by calling
+    QGestureEvent::accept() for each of them, or an event filter consumes the
+    event.
+
+    \section1 Further Reading
+
+    For an overview of gesture handling in Qt and information on using gestures
+    in your applications, see the \l{Gestures Programming} document.

+
+  In particular:

+    [call with item1 = label, item2 = null, prevItem1 & prevItem2 as before]

+
+ [if the next row has one item, 'item']
+  3a) the following row's vspace needs to be changed to item/field spacing (would

+
+  In the (common) non split case, we can just use the precalculated vspace (possibly qMaxed between
+  label and field).
+

+  -  item2 can be null

+    \class QFormLayout
+    \since 4.4
+    \brief The QFormLayout class manages forms of input widgets and their associated labels.
+
+    \ingroup geomanagement
+
+
+    QFormLayout is a convenience layout class that lays out its
+    children in a two-column form. The left column consists of labels
+    and the right column consists of "field" widgets (line editors,
+    spin boxes, etc.).
+
+    Traditionally, such two-column form layouts were achieved using
+    QGridLayout. QFormLayout is a higher-level alternative that
+    provides the following advantages:
+
+    \list
+    \o \bold{Adherence to the different platform's look and feel guidelines.}
+
+        For example, the
+        \l{Mac OS X Aqua} and KDE guidelines specify that the
+        labels should be right-aligned, whereas Windows and GNOME
+        applications normally use left-alignment.
+
+    \o \bold{Support for wrapping long rows.}
+
+       For devices with small displays, QFormLayout can be set to
+       \l{WrapLongRows}{wrap long rows}, or even to
+       \l{WrapAllRows}{wrap all rows}.
+
+    \o \bold{Convenient API for creating label--field pairs.}
+
+       The addRow() overload that takes a QString and a QWidget *
+       creates a QLabel behind the scenes and automatically set up
+       its buddy. We can then write code like this:
+
+    \snippet doc/src/snippets/code/src_gui_kernel_qformlayout.cpp 0
+
+       Compare this with the following code, written using QGridLayout:
+
+    \snippet doc/src/snippets/code/src_gui_kernel_qformlayout.cpp 1
+    \endlist
+
+    The table below shows the default appearance in different styles.
+
+    \table
+    \header
+        \o QCommonStyle derived styles (except QPlastiqueStyle)
+        \o QMacStyle
+        \o QPlastiqueStyle
+        \o Qt Extended styles
+    \row
+        \o \inlineimage qformlayout-win.png
+        \o \inlineimage qformlayout-mac.png
+        \o \inlineimage qformlayout-kde.png
+        \o \inlineimage qformlayout-qpe.png
+    \row
+        \o Traditional style used for Windows, GNOME, and earlier
+           versions of KDE. Labels are left aligned, and expanding
+           fields grow to fill the available space. (This normally
+           corresponds to what we would get using a two-column
+           QGridLayout.)
+        \o Style based on the
+           \l{Mac OS X Aqua} guidelines. Labels are right-aligned,
+           the fields don't grow beyond their size hint, and the
+           form is horizontally centered.
+        \o Recommended style for
+           \l{KDE applications}. Similar to MacStyle, except that the form
+           is left-aligned and all fields grow to fill the available
+           space.
+        \o Default style for Qt Extended styles. Labels are right-aligned,
+           expanding fields grow to fill the available space, and row
+           wrapping is enabled for long lines.
+    \endtable
+
+    The form styles can be also be overridden individually by calling
+    setLabelAlignment(), setFormAlignment(), setFieldGrowthPolicy(),
+    and setRowWrapPolicy().  For example, to simulate the form layout
+    appearance of QMacStyle on all platforms, but with left-aligned
+    labels, you could write:

+    the QGestureRecognizer object that is registered with the application; see
+    QGestureRecognizer::registerRecognizer().
+
+    For an overview of gesture handling in Qt and information on using gestures
+    in your applications, see the \l{Gestures Programming} document.
+
+    \section1 Gesture Properties
+
+    The class has a list of properties that can be queried by the user to get
+    some gesture-specific arguments. For example, the pinch gesture has a scale
+    factor that is exposed as a property.
+
+    Developers of custom gesture recognizers can add additional properties in
+    order to provide additional information about a gesture. This can be done
+    by adding new dynamic properties to a QGesture object, or by subclassing
+    the QGesture class (or one of its subclasses).
+
+    \section1 Lifecycle of a Gesture Object
+
+    A QGesture instance is implicitly created when needed and is owned by Qt.
+    Developers should never destroy them or store them for later use as Qt may
+    destroy particular instances of them and create new ones to replace them.
+
+    The registered gesture recognizer monitors the input events for the target
+    object via its \l{QGestureRecognizer::}{recognize()} function, updating the
+    properties of the gesture object as required.
+
+    The gesture object may be delivered to the target object in a QGestureEvent if
+    the corresponding gesture is active or has just been canceled. Each event that
+    is delivered contains a list of gesture objects, since support for more than
+    one gesture may be enabled for the target object. Due to the way events are
+    handled in Qt, gesture events may be filtered by other objects.

+/*!
+   \class QGestureRecognizer
+   \since 4.6
+   \brief The QGestureRecognizer class provides the infrastructure for gesture recognition.
+   \ingroup gestures
+
+   Gesture recognizers are responsible for creating and managing QGesture objects and
+   monitoring input events sent to QWidget and QGraphicsObject subclasses.
+   QGestureRecognizer is the base class for implementing custom gestures.
+
+   Developers that only need to provide gesture recognition for standard gestures do not
+   need to use this class directly. Instances will be created behind the scenes by the
+   framework.
+
+   For an overview of gesture handling in Qt and information on using gestures
+   in your applications, see the \l{Gestures Programming} document.
+
+   \section1 Recognizing Gestures
+
+   The process of recognizing gestures involves filtering input events sent to specific
+   objects, and modifying the associated QGesture objects to include relevant information
+   about the user's input.
+
+   Gestures are created when the framework calls create() to handle user input
+   for a particular instance of a QWidget or QGraphicsObject subclass. A QGesture object
+   is created for each widget or item that is configured to use gestures.
+
+   Once a QGesture has been created for a target object, the gesture recognizer will
+   receive events for it in its recognize() handler function.
+
+   When a gesture is canceled, the reset() function is called, giving the recognizer the
+   chance to update the appropriate properties in the corresponding QGesture object.
+
+   \section1 Supporting New Gestures
+
+   To add support for new gestures, you need to derive from QGestureRecognizer to create
+   a custom recognizer class, construct an instance of this class, and register it with
+   the application by calling QGestureRecognizer::registerRecognizer(). You can also
+   subclass QGesture to create a custom gesture class, or rely on dynamic properties
+   to express specific details of the gesture you want to handle.
+
+   Your custom QGestureRecognizer subclass needs to reimplement the recognize()
+   function to handle and filter the incoming input events for QWidget and
+   QGraphicsObject subclasses. Although the logic for gesture recognition is
+   implemented in this function, you can store persistent information about the
+   state of the recognition process in the QGesture object supplied. The
+   recognize() function must return a value of QGestureRecognizer::Result that
+   indicates the state of recognition for a given gesture and target object.
+   This determines whether or not a gesture event will be delivered to a target
+   object.
+
+   If you choose to represent a gesture by a custom QGesture subclass, you will need to
+   reimplement the create() function to construct instances of your gesture class.
+   Similarly, you may need to reimplement the reset() function if your custom gesture
+   objects need to be specially handled when a gesture is canceled.
+
+   \sa QGesture
+*/
+
+/*!
+    \enum QGestureRecognizer::ResultFlag
+
+    This enum describes the result of the current event filtering step in
+    a gesture recognizer state machine.
+
+    The result consists of a state value (one of Ignore, MayBeGesture,
+    TriggerGesture, FinishGesture, CancelGesture) and an optional hint
+    (ConsumeEventHint).
+
+    \value Ignore The event does not change the state of the recognizer.
+
+    \value MayBeGesture The event changed the internal state of the recognizer,
+    but it isn't clear yet if it is a gesture or not. The recognizer needs to
+    filter more events to decide. Gesture recognizers in the MayBeGesture state
+    may be reset automatically if they take too long to recognize gestures.
+
+    \value TriggerGesture The gesture has been triggered and the appropriate
+    QGesture object will be delivered to the target as a part of a
+    QGestureEvent.
+
+    \value FinishGesture The gesture has been finished successfully and the
+    appropriate QGesture object will be delivered to the target as a part of a
+    QGestureEvent.
+
+    \value CancelGesture The event made it clear that it is not a gesture. If
+    the gesture recognizer was in GestureTriggered state before, then the
+    gesture is canceled and the appropriate QGesture object will be delivered
+    to the target as a part of a QGestureEvent.
+
+    \value ConsumeEventHint This hint specifies that the gesture framework
+    should consume the filtered event and not deliver it to the receiver.

+/*!
+    \class QGridLayout
+
+    \brief The QGridLayout class lays out widgets in a grid.
+
+    \ingroup geomanagement
+
+
+    QGridLayout takes the space made available to it (by its parent
+    layout or by the parentWidget()), divides it up into rows and
+    columns, and puts each widget it manages into the correct cell.
+
+    Columns and rows behave identically; we will discuss columns, but
+    there are equivalent functions for rows.
+
+    Each column has a minimum width and a stretch factor. The minimum
+    width is the greatest of that set using setColumnMinimumWidth() and the
+    minimum width of each widget in that column. The stretch factor is
+    set using setColumnStretch() and determines how much of the available
+    space the column will get over and above its necessary minimum.
+
+    Normally, each managed widget or layout is put into a cell of its
+    own using addWidget(). It is also possible for a widget to occupy
+    multiple cells using the row and column spanning overloads of
+    addItem() and addWidget(). If you do this, QGridLayout will guess
+    how to distribute the size over the columns/rows (based on the
+    stretch factors).
+
+    To remove a widget from a layout, call removeWidget(). Calling
+    QWidget::hide() on a widget also effectively removes the widget
+    from the layout until QWidget::show() is called.
+
+    This illustration shows a fragment of a dialog with a five-column,
+    three-row grid (the grid is shown overlaid in magenta):
+
+    \image gridlayout.png A grid layout
+
+    Columns 0, 2 and 4 in this dialog fragment are made up of a
+    QLabel, a QLineEdit, and a QListBox. Columns 1 and 3 are
+    placeholders made with setColumnMinimumWidth(). Row 0 consists of three
+    QLabel objects, row 1 of three QLineEdit objects and row 2 of
+    three QListBox objects. We used placeholder columns (1 and 3) to
+    get the right amount of space between the columns.
+
+    Note that the columns and rows are not equally wide or tall. If
+    you want two columns to have the same width, you must set their
+    minimum widths and stretch factors to be the same yourself. You do
+    this using setColumnMinimumWidth() and setColumnStretch().
+
+    If the QGridLayout is not the top-level layout (i.e. does not
+    manage all of the widget's area and children), you must add it to
+    its parent layout when you create it, but before you do anything
+    with it. The normal way to add a layout is by calling
+    addLayout() on the parent layout.
+
+    Once you have added your layout you can start putting widgets and
+    other layouts into the cells of your grid layout using
+    addWidget(), addItem(), and addLayout().
+
+    QGridLayout also includes two margin widths:
+    the \l{getContentsMargins()}{contents margin} and the spacing().
+    The contents margin is the width of the reserved space along each
+    of the QGridLayout's four sides. The spacing() is the width of the
+    automatically allocated spacing between neighboring boxes.
+
+    The default contents margin values are provided by the
+    \l{QStyle::pixelMetric()}{style}. The default value Qt styles specify
+    is 9 for child widgets and 11 for windows. The spacing defaults to the same as
+    the margin width for a top-level layout, or to the same as the
+    parent layout.

+    \class QKeySequence
+    \brief The QKeySequence class encapsulates a key sequence as used
+    by shortcuts.
+
+    \ingroup shared
+
+
+    In its most common form, a key sequence describes a combination of
+    keys that must be used together to perform some action. Key sequences
+    are used with QAction objects to specify which keyboard shortcuts can
+    be used to trigger actions.
+
+    Key sequences can be constructed for use as keyboard shortcuts in
+    three different ways:
+
+    \list
+    \o For standard shortcuts, a \l{QKeySequence::StandardKey}{standard key}
+       can be used to request the platform-specific key sequence associated
+       with each shortcut.
+    \o For custom shortcuts, human-readable strings such as "Ctrl+X" can
+       be used, and these can be translated into the appropriate shortcuts
+       for users of different languages. Translations are made in the
+       "QShortcut" context.
+    \o For hard-coded shortcuts, integer key codes can be specified with
+       a combination of values defined by the Qt::Key and Qt::Modifier enum
+       values. Each key code consists of a single Qt::Key value and zero or
+       more modifiers, such as Qt::SHIFT, Qt::CTRL, Qt::ALT and Qt::META.
+    \endlist
+
+    For example, \gui{Ctrl P} might be a sequence used as a shortcut for
+    printing a document, and can be specified in any of the following
+    ways:
+
+    \snippet doc/src/snippets/code/src_gui_kernel_qkeysequence.cpp 0
+
+    Note that, for letters, the case used in the specification string
+    does not matter. In the above examples, the user does not need to
+    hold down the \key{Shift} key to activate a shortcut specified
+    with "Ctrl+P". However, for other keys, the use of \key{Shift} as
+    an unspecified extra modifier key can lead to confusion for users
+    of an application whose keyboards have different layouts to those
+    used by the developers. See the \l{Keyboard Layout Issues} section
+    below for more details.
+
+    It is preferable to use standard shortcuts where possible.
+    When creating key sequences for non-standard shortcuts, you should use
+    human-readable strings in preference to hard-coded integer values.
+
+    QKeySequence objects can be cast to a QString to obtain a human-readable
+    translated version of the sequence. Similarly, the toString() function
+    produces human-readable strings for use in menus. On Mac OS X, the
+    appropriate symbols are used to describe keyboard shortcuts using special
+    keys on the Macintosh keyboard.
+
+    An alternative way to specify hard-coded key codes is to use the Unicode
+    code point of the character; for example, 'A' gives the same key sequence
+    as Qt::Key_A.
+
+    \bold{Note:} On Mac OS X, references to "Ctrl", Qt::CTRL, Qt::Control
+    and Qt::ControlModifier correspond to the \key Command keys on the
+    Macintosh keyboard, and references to "Meta", Qt::META, Qt::Meta and
+    Qt::MetaModifier correspond to the \key Control keys. Developers on
+    Mac OS X can use the same shortcut descriptions across all platforms,
+    and their applications will automatically work as expected on Mac OS X.
+
+    \section1 Standard Shortcuts
+
+    QKeySequence defines many \l{QKeySequence::StandardKey} {standard
+    keyboard shortcuts} to reduce the amount of effort required when
+    setting up actions in a typical application. The table below shows
+    some common key sequences that are often used for these standard
+    shortcuts by applications on four widely-used platforms.  Note
+    that on Mac OS X, the \key Ctrl value corresponds to the \key
+    Command keys on the Macintosh keyboard, and the \key Meta value
+    corresponds to the \key Control keys.

+
+    Note that, since the key sequences used for the standard shortcuts differ
+    between platforms, you still need to test your shortcuts on each platform
+    to ensure that you do not unintentionally assign the same key sequence to
+    many actions.
+
+    \section1 Keyboard Layout Issues
+
+    Many key sequence specifications are chosen by developers based on the
+    layout of certain types of keyboard, rather than choosing keys that
+    represent the first letter of an action's name, such as \key{Ctrl S}
+    ("Ctrl+S") or \key{Ctrl C} ("Ctrl+C").
+    Additionally, because certain symbols can only be entered with the
+    help of modifier keys on certain keyboard layouts, key sequences intended
+    for use with one keyboard layout may map to a different key, map to no
+    keys at all, or require an additional modifier key to be used on
+    different keyboard layouts.
+
+    For example, the shortcuts, \key{Ctrl plus} and \key{Ctrl minus}, are often
+    used as shortcuts for zoom operations in graphics applications, and these
+    may be specified as "Ctrl++" and "Ctrl+-" respectively. However, the way
+    these shortcuts are specified and interpreted depends on the keyboard layout.
+    Users of Norwegian keyboards will note that the \key{+} and \key{-} keys
+    are not adjacent on the keyboard, but will still be able to activate both
+    shortcuts without needing to press the \key{Shift} key. However, users
+    with British keyboards will need to hold down the \key{Shift} key
+    to enter the \key{+} symbol, making the shortcut effectively the same as
+    "Ctrl+Shift+=".
+
+    Although some developers might resort to fully specifying all the modifiers
+    they use on their keyboards to activate a shortcut, this will also result
+    in unexpected behavior for users of different keyboard layouts.
+
+    For example, a developer using a British keyboard may decide to specify
+    "Ctrl+Shift+=" as the key sequence in order to create a shortcut that
+    coincidentally behaves in the same way as \key{Ctrl plus}. However, the
+    \key{=} key needs to be accessed using the \key{Shift} key on Norwegian
+    keyboard, making the required shortcut effectively \key{Ctrl Shift Shift =}
+    (an impossible key combination).
+
+    As a result, both human-readable strings and hard-coded key codes
+    can both be problematic to use when specifying a key sequence that
+    can be used on a variety of different keyboard layouts. Only the
+    use of \l{QKeySequence::StandardKey} {standard shortcuts}
+    guarantees that the user will be able to use the shortcuts that
+    the developer intended.
+
+    Despite this, we can address this issue by ensuring that human-readable
+    strings are used, making it possible for translations of key sequences to
+    be made for users of different languages. This approach will be successful
+    for users whose keyboards have the most typical layout for the language
+    they are using.
+
+    \section1 GNU Emacs Style Key Sequences
+
+    Key sequences similar to those used in \l{GNU Emacs}, allowing up to four
+    key codes, can be created by using the multiple argument constructor,
+    or by passing a human-readable string of comma-separated key sequences.
+
+    For example, the key sequence, \key{Ctrl X} followed by \key{Ctrl C}, can
+    be specified using either of the following ways:
+
+    \snippet doc/src/snippets/code/src_gui_kernel_qkeysequence.cpp 1

+    \class QLayout
+    \brief The QLayout class is the base class of geometry managers.
+
+    \ingroup geomanagement
+
+    This is an abstract base class inherited by the concrete classes
+    QBoxLayout, QGridLayout, QFormLayout, and QStackedLayout.
+
+    For users of QLayout subclasses or of QMainWindow there is seldom
+    any need to use the basic functions provided by QLayout, such as
+    setSizeConstraint() or setMenuBar(). See \l{Layout Management}
+    for more information.
+
+    To make your own layout manager, implement the functions
+    addItem(), sizeHint(), setGeometry(), itemAt() and takeAt(). You
+    should also implement minimumSize() to ensure your layout isn't
+    resized to zero size if there is too little space. To support
+    children whose heights depend on their widths, implement
+    hasHeightForWidth() and heightForWidth(). See the
+    \l{layouts/borderlayout}{Border Layout} and
+    \l{layouts/flowlayout}{Flow Layout} examples for
+    more information about implementing custom layout managers.
+
+    Geometry management stops when the layout manager is deleted.

+
+    This is used by custom layouts.
+
+    Pure virtual functions are provided to return information about
+    the layout, including, sizeHint(), minimumSize(), maximumSize()
+    and expanding().
+
+    The layout's geometry can be set and retrieved with setGeometry()
+    and geometry(), and its alignment with setAlignment() and
+    alignment().
+
+    isEmpty() returns whether the layout item is empty. If the
+    concrete item is a QWidget, it can be retrieved using widget().
+    Similarly for layout() and spacerItem().
+
+    Some layouts have width and height interdependencies. These can
+    be expressed using hasHeightForWidth(), heightForWidth(), and
+    minimumHeightForWidth(). For more explanation see the \e{Qt

+  \class QMacPasteboardMime
+  \brief The QMacPasteboardMime class converts between a MIME type and a
+  \l{http://developer.apple.com/macosx/uniformtypeidentifiers.html}{Uniform
+  Type Identifier (UTI)} format.
+  \since 4.2
+
+  \ingroup draganddrop
+
+  Qt's drag and drop and clipboard facilities use the MIME
+  standard. On X11, this maps trivially to the Xdnd protocol. On
+  Mac, although some applications use MIME to describe clipboard
+  contents, it is more common to use Apple's UTI format.
+
+  QMacPasteboardMime's role is to bridge the gap between MIME and UTI;
+  By subclasses this class, one can extend Qt's drag and drop
+  and clipboard handling to convert to and from unsupported, or proprietary, UTI formats.
+
+  A subclass of QMacPasteboardMime will automatically be registered, and active, upon instantiation.
+
+  Qt has predefined support for the following UTIs:
+  \list
+    \i public.utf8-plain-text - converts to "text/plain"
+    \i public.utf16-plain-text - converts to "text/plain"
+    \i public.html - converts to "text/html"
+    \i public.url - converts to "text/uri-list"
+    \i public.file-url - converts to "text/uri-list"
+    \i public.tiff - converts to "application/x-qt-image"
+    \i public.vcard - converts to "text/plain"
+    \i com.apple.traditional-mac-plain-text - converts to "text/plain"
+    \i com.apple.pict - converts to "application/x-qt-image"
+  \endlist
+
+  When working with MIME data, Qt will interate through all instances of QMacPasteboardMime to
+  find an instance that can convert to, or from, a specific MIME type. It will do this by calling
+  canConvert() on each instance, starting with (and choosing) the last created instance first.
+  The actual conversions will be done by using convertToMime() and convertFromMime().
+
+  \note The API uses the term "flavor" in some cases. This is for backwards
+  compatibility reasons, and should now be understood as UTIs.

+    \class QWindowsMime
+    \brief The QWindowsMime class maps open-standard MIME to Window Clipboard formats.
+    \ingroup draganddrop
+
+    Qt's drag-and-drop and clipboard facilities use the MIME standard.
+    On X11, this maps trivially to the Xdnd protocol, but on Windows
+    although some applications use MIME types to describe clipboard
+    formats, others use arbitrary non-standardized naming conventions,
+    or unnamed built-in formats of Windows.
+
+    By instantiating subclasses of QWindowsMime that provide conversions
+    between Windows Clipboard and MIME formats, you can convert
+    proprietary clipboard formats to MIME formats.
+
+    Qt has predefined support for the following Windows Clipboard formats:
+
+    \table
+    \header \o Windows Format \o Equivalent MIME type
+    \row \o \c CF_UNICODETEXT \o \c text/plain
+    \row \o \c CF_TEXT        \o \c text/plain
+    \row \o \c CF_DIB         \o \c{image/xyz}, where \c xyz is
+                                 a \l{QImageWriter::supportedImageFormats()}{Qt image format}
+    \row \o \c CF_HDROP       \o \c text/uri-list
+    \row \o \c CF_INETURL     \o \c text/uri-list
+    \row \o \c CF_HTML        \o \c text/html
+    \endtable
+
+    An example use of this class would be to map the Windows Metafile
+    clipboard format (\c CF_METAFILEPICT) to and from the MIME type
+    \c{image/x-wmf}. This conversion might simply be adding or removing
+    a header, or even just passing on the data. See \l{Drag and Drop}
+    for more information on choosing and definition MIME types.
+
+    You can check if a MIME type is convertible using canConvertFromMime() and
+    can perform conversions with convertToMime() and convertFromMime().

+    \class QPalette
+
+    \brief The QPalette class contains color groups for each widget state.
+
+    \ingroup appearance
+    \ingroup shared
+    \ingroup painting
+
+
+    A palette consists of three color groups: \e Active, \e Disabled,
+    and \e Inactive. All widgets in Qt contain a palette and
+    use their palette to draw themselves. This makes the user
+    interface easily configurable and easier to keep consistent.
+
+
+    If you create a new widget we strongly recommend that you use the
+    colors in the palette rather than hard-coding specific colors.
+
+    The color groups:
+    \list
+    \i The Active group is used for the window that has keyboard focus.
+    \i The Inactive group is used for other windows.
+    \i The Disabled group is used for widgets (not windows) that are
+    disabled for some reason.
+    \endlist
+
+    Both active and inactive windows can contain disabled widgets.
+    (Disabled widgets are often called \e inaccessible or \e{grayed
+    out}.)
+
+    In most styles, Active and Inactive look the same.
+
+    Colors and brushes can be set for particular roles in any of a palette's
+    color groups with setColor() and setBrush().  A color group contains a
+    group of colors used by widgets for drawing themselves. We recommend that
+    widgets use color group roles from the palette such as "foreground" and
+    "base" rather than literal colors like "red" or "turquoise". The color
+    roles are enumerated and defined in the \l ColorRole documentation.
+
+    We strongly recommend that you use the default palette of the
+    current style (returned by QApplication::palette()) and
+    modify that as necessary. This is done by Qt's widgets when they
+    are drawn.
+
+    To modify a color group you call the functions
+    setColor() and setBrush(), depending on whether you want a pure
+    color or a pixmap pattern.
+
+    There are also corresponding color() and brush() getters, and a
+    commonly used convenience function to get the ColorRole for the current ColorGroup:
+    window(), windowText(), base(), etc.
+
+
+    You can copy a palette using the copy constructor and test to see
+    if two palettes are \e identical using isCopyOf().
+
+    QPalette is optimized by the use of \l{implicit sharing},
+    so it is very efficient to pass QPalette objects as arguments.
+
+    \warning Some styles do not use the palette for all drawing, for
+    instance, if they make use of native theme engines. This is the
+    case for both the Windows XP, Windows Vista, and the Mac OS X
+    styles.

+    \enum QPalette::ColorRole
+
+    \img palette.png Color Roles
+
+    The ColorRole enum defines the different symbolic color roles used
+    in current GUIs.
+
+    The central roles are:
+
+    \value Window  A general background color.
+
+    \value Background  This value is obsolete. Use Window instead.
+
+    \value WindowText  A general foreground color.
+
+    \value Foreground  This value is obsolete. Use WindowText instead.
+
+    \value Base  Used mostly as the background color for text entry widgets,
+                 but can also be used for other painting - such as the
+                 background of combobox drop down lists and toolbar handles.
+                 It is usually white or another light color.
+
+    \value AlternateBase  Used as the alternate background color in views with
+                          alternating row colors (see
+                          QAbstractItemView::setAlternatingRowColors()).
+
+    \value ToolTipBase Used as the background color for QToolTip and
+                          QWhatsThis. Tool tips use the Inactive color group
+                          of QPalette, because tool tips are not active
+                          windows.
+
+    \value ToolTipText Used as the foreground color for QToolTip and
+                          QWhatsThis. Tool tips use the Inactive color group
+                          of QPalette, because tool tips are not active
+                          windows.
+
+    \value Text  The foreground color used with \c Base. This is usually
+                 the same as the \c WindowText, in which case it must provide
+                 good contrast with \c Window and \c Base.
+
+    \value Button The general button background color. This background can be different from
+                  \c Window as some styles require a different background color for buttons.
+
+    \value ButtonText  A foreground color used with the \c Button color.
+
+    \value BrightText  A text color that is very different from
+                       \c WindowText, and contrasts well with e.g. \c
+                       Dark. Typically used for text that needs to be
+                       drawn where \c Text or \c WindowText would give
+                       poor contrast, such as on pressed push buttons.
+                       Note that text colors can be used for things
+                       other than just words; text colors are \e
+                       usually used for text, but it's quite common to
+                       use the text color roles for lines, icons, etc.
+
+
+    There are some color roles used mostly for 3D bevel and shadow effects.
+    All of these are normally derived from \c Window, and used in ways that
+    depend on that relationship. For example, buttons depend on it to make the
+    bevels look attractive, and Motif scroll bars depend on \c Mid to be
+    slightly different from \c Window.
+
+    \value Light  Lighter than \c Button color.
+
+    \value Midlight  Between \c Button and \c Light.
+
+    \value Dark  Darker than \c Button.
+
+    \value Mid  Between \c Button and \c Dark.
+
+    \value Shadow  A very dark color. By default, the shadow color is
+                   Qt::black.
+
+
+    Selected (marked) items have two roles:
+
+    \value Highlight   A color to indicate a selected item or the current
+                       item. By default, the highlight color is
+                       Qt::darkBlue.
+
+    \value HighlightedText  A text color that contrasts with \c Highlight.
+                            By default, the highlighted text color is Qt::white.
+
+    There are two color roles related to hyperlinks:
+
+    \value Link  A text color used for unvisited hyperlinks.
+                 By default, the link color is Qt::blue.
+
+    \value LinkVisited  A text color used for already visited hyperlinks.
+                        By default, the linkvisited color is Qt::magenta.
+
+    Note that we do not use the \c Link and \c LinkVisited roles when
+    rendering rich text in Qt, and that we recommend that you use CSS
+    and the QTextDocument::setDefaultStyleSheet() function to alter
+    the appearance of links. For example:
+
+    \snippet doc/src/snippets/textdocument-css/main.cpp 0
+
+    \value NoRole No role; this special role is often used to indicate that a
+    role has not been assigned.

+
+    In QPA the way to support OpenGL or OpenVG or other technologies that requires a native GL
+    context is through the QPlatformGLContext wrapper.
+
+    There is no factory function for QPlatformGLContexts, but rather only one accessor function.
+    The only place to retrieve a QPlatformGLContext from is through a QPlatformWindow.
+
+    The context which is current for a specific thread can be collected by the currentContext()
+    function. This is how QPlatformGLContext also makes it possible to use the QtOpenGL module
+    withhout using QGLWidget. When using QGLContext::currentContext(), it will ask
+    QPlatformGLContext for the currentContext. Then a corresponding QGLContext will be returned,
+    which maps to the QPlatformGLContext.

+    \brief The QPlatformIntegration class is the entry for WindowSystem specific functionality.
+
+    QPlatformIntegration is the single entry point for windowsystem specific functionality when
+    using the QPA platform. It has factory functions for creating platform specific pixmaps and
+    windows. The class also controls the font subsystem.
+
+    QPlatformIntegration is a singelton class which gets instansiated in the QApplication
+    constructor. The QPlatformIntegration instance do not have ownership of objects it creates in
+    functions where the name starts with create. However, functions which don't have a name
+    starting with create acts as assessors to member variables.
+
+    It is not trivial to create or build a platform plugin outside of the Qt source tree. Therefor
+    the recommended approach for making new platform plugin is to copy an existing plugin inside
+    the QTSRCTREE/src/plugins/platform and develop the plugin inside the source tree.
+
+    The minimal platformintegration is the smallest platform integration it is possible to make,
+    which makes it an ideal starting point for new plugins. For a slightly more advanced plugin,
+    consider reviewing the directfb plugin, or the testlite plugin.

+
+    The QPlatformWindow abstraction is used by QWidget for all its top level widgets. It is being
+    created by calling the createPlatformWindow function in the loaded QPlatformIntegration
+    instance.
+
+    QPlatformWindow is used to signal to the windowing system, how Qt persieves its frame.
+    However, it is not concerned with how Qt renders into the window it represents.
+
+    Top level QWidgets(tlw) will always have a QPlatformWindow. However, it is not necessary for
+    all tlw to have a QWindowSurface. This is the case for QGLWidget. And could be the case for
+    widgets where some  3.party renders into it.
+
+    The platform specific window handle can be retrieved by the winId function.
+
+    QPlatformWindow is also the way QPA defines how native child windows should be supported
+    through the setParent function.
+
+    The only way to retrieve a QPlatformGLContext in QPA is by calling the glContext() function
+    on QPlatformWindow.

+    \class QPlatformWindowFormat
+    \brief The QPlatformWindowFormat class specifies the display format of an OpenGL
+    rendering context and if possible attributes of the corresponding QPlatformWindow.
+
+    \ingroup painting
+
+    QWidget has a setter and getter function for QPlatformWindowFormat. These functions can be used
+    by the application programmer to signal what kind of format he wants to the window and glcontext
+    should have. However, it is not always possible to fulfill these requirements. The application
+    programmer should therefore check the resulting QPlatformWindowFormat from QPlatformGLContext
+    to see the format that was actually created.
+
+    A display format has several characteristics:
+    \list
+    \i \link setDoubleBuffer() Double or single buffering.\endlink
+    \i \link setDepth() Depth buffer.\endlink
+    \i \link setRgba() RGBA or color index mode.\endlink
+    \i \link setAlpha() Alpha channel.\endlink
+    \i \link setAccum() Accumulation buffer.\endlink
+    \i \link setStencil() Stencil buffer.\endlink
+    \i \link setStereo() Stereo buffers.\endlink
+    \i \link setDirectRendering() Direct rendering.\endlink
+    \i \link setOverlay() Presence of an overlay.\endlink
+    \i \link setPlane() Plane of an overlay.\endlink
+    \i \link setSampleBuffers() Multisample buffers.\endlink
+    \endlist
+
+    You can also specify preferred bit depths for the color buffer,
+    depth buffer, alpha buffer, accumulation buffer and the stencil
+    buffer with the functions: setRedBufferSize(), setGreenBufferSize(),
+    setBlueBufferSize(), setDepthBufferSize(), setAlphaBufferSize(),
+    setAccumBufferSize() and setStencilBufferSize().
+
+    Note that even if you specify that you prefer a 32 bit depth
+    buffer (e.g. with setDepthBufferSize(32)), the format that is
+    chosen may not have a 32 bit depth buffer, even if there is a
+    format available with a 32 bit depth buffer. The main reason for
+    this is how the system dependant picking algorithms work on the
+    different platforms, and some format options may have higher
+    precedence than others.
+
+    You create and tell a QPlatformWindowFormat object what rendering options you
+    want from an OpenGL rendering context.
+
+    OpenGL drivers or accelerated hardware may or may not support
+    advanced features such as alpha channel or stereographic viewing.
+    If you request some features that the driver/hardware does not
+    provide when you create a QGLWidget, you will get a rendering
+    context with the nearest subset of features.
+
+    There are different ways to define the display characteristics of
+    a rendering context. One is to create a QPlatformWindowFormat and make it the
+    default for the entire application:
+    \snippet doc/src/snippets/code/src_opengl_qgl.cpp 0
+
+    Or you can specify the desired format when creating an object of
+    your QGLWidget subclass:
+    \snippet doc/src/snippets/code/src_opengl_qgl.cpp 1
+
+    After the widget has been created, you can find out which of the
+    requested features the system was able to provide:
+    \snippet doc/src/snippets/code/src_opengl_qgl.cpp 2
+
+    \legalese

+/*!
+    \class QShortcut
+    \brief The QShortcut class is used to create keyboard shortcuts.
+
+    \ingroup events
+
+
+    The QShortcut class provides a way of connecting keyboard
+    shortcuts to Qt's \l{signals and slots} mechanism, so that
+    objects can be informed when a shortcut is executed. The shortcut
+    can be set up to contain all the key presses necessary to
+    describe a keyboard shortcut, including the states of modifier
+    keys such as \gui Shift, \gui Ctrl, and \gui Alt.
+
+    \target mnemonic
+
+    On certain widgets, using '&' in front of a character will
+    automatically create a mnemonic (a shortcut) for that character,
+    e.g. "E&xit" will create the shortcut \gui Alt+X (use '&&' to
+    display an actual ampersand). The widget might consume and perform
+    an action on a given shortcut. On X11 the ampersand will not be
+    shown and the character will be underlined. On Windows, shortcuts
+    are normally not displayed until the user presses the \gui Alt
+    key, but this is a setting the user can change. On Mac, shortcuts
+    are disabled by default. Call qt_set_sequence_auto_mnemonic() to
+    enable them. However, because mnemonic shortcuts do not fit in
+    with Aqua's guidelines, Qt will not show the shortcut character
+    underlined.
+
+    For applications that use menus, it may be more convenient to
+    use the convenience functions provided in the QMenu class to
+    assign keyboard shortcuts to menu items as they are created.
+    Alternatively, shortcuts may be associated with other types of
+    actions in the QAction class.
+
+    The simplest way to create a shortcut for a particular widget is
+    to construct the shortcut with a key sequence. For example:
+
+    \snippet doc/src/snippets/code/src_gui_kernel_qshortcut.cpp 0
+
+    When the user types the \l{QKeySequence}{key sequence}
+    for a given shortcut, the shortcut's activated() signal is
+    emitted. (In the case of ambiguity, the activatedAmbiguously()
+    signal is emitted.) A shortcut is "listened for" by Qt's event
+    loop when the shortcut's parent widget is receiving events.
+
+    A shortcut's key sequence can be set with setKey() and retrieved
+    with key(). A shortcut can be enabled or disabled with
+    setEnabled(), and can have "What's This?" help text set with
+    setWhatsThis().

+    When a shortcut's key sequence is completed,
+    activatedAmbiguously() is emitted if the key sequence is still
+    ambiguous (i.e., it is the start of one or more other shortcuts).

+/*!
+    \class QSizePolicy
+    \brief The QSizePolicy class is a layout attribute describing horizontal
+    and vertical resizing policy.
+
+    \ingroup geomanagement
+
+    The size policy of a widget is an expression of its willingness to
+    be resized in various ways, and affects how the widget is treated
+    by the \l{Layout Management}{layout engine}. Each widget returns a
+    QSizePolicy that describes the horizontal and vertical resizing
+    policy it prefers when being laid out. You can change this for
+    a specific widget by changing its QWidget::sizePolicy property.
+
+    QSizePolicy contains two independent QSizePolicy::Policy values
+    and two stretch factors; one describes the widgets's horizontal
+    size policy, and the other describes its vertical size policy. It
+    also contains a flag to indicate whether the height and width of
+    its preferred size are related.
+
+    The horizontal and vertical policies can be set in the
+    constructor, and altered using the setHorizontalPolicy() and
+    setVerticalPolicy() functions. The stretch factors can be set
+    using the setHorizontalStretch() and setVerticalStretch()
+    functions. The flag indicating whether the widget's
+    \l{QWidget::sizeHint()}{sizeHint()} is width-dependent (such as a
+    menu bar or a word-wrapping label) can be set using the
+    setHeightForWidth() function.
+
+    The current size policies and stretch factors be retrieved using
+    the horizontalPolicy(), verticalPolicy(), horizontalStretch() and
+    verticalStretch() functions. Alternatively, use the transpose()
+    function to swap the horizontal and vertical policies and
+    stretches. The hasHeightForWidth() function returns the current
+    status of the flag indicating the size hint dependencies.
+
+    Use the expandingDirections() function to determine whether the
+    associated widget can make use of more space than its
+    \l{QWidget::sizeHint()}{sizeHint()} function indicates, as well as
+    find out in which directions it can expand.
+
+    Finally, the QSizePolicy class provides operators comparing this
+    size policy to a given policy, as well as a QVariant operator
+    storing this QSizePolicy as a QVariant object.

+    \enum QSizePolicy::PolicyFlag
+
+    These flags are combined together to form the various \l{Policy}

+    \value ExpandFlag  The widget should get as much space as possible.

+    \enum QSizePolicy::Policy
+
+    This enum describes the various per-dimension sizing types used
+    when constructing a QSizePolicy.
+
+    \value Fixed  The QWidget::sizeHint() is the only acceptable
+        alternative, so the widget can never grow or shrink (e.g. the
+        vertical direction of a push button).
+
+    \value Minimum  The sizeHint() is minimal, and sufficient. The
+        widget can be expanded, but there is no advantage to it being
+        larger (e.g. the horizontal direction of a push button).
+        It cannot be smaller than the size provided by sizeHint().
+
+    \value Maximum  The sizeHint() is a maximum. The widget can be
+        shrunk any amount without detriment if other widgets need the
+        space (e.g. a separator line).
+        It cannot be larger than the size provided by sizeHint().
+
+    \value Preferred  The sizeHint() is best, but the widget can be
+        shrunk and still be useful. The widget can be expanded, but there
+        is no advantage to it being larger than sizeHint() (the default
+        QWidget policy).
+
+    \value Expanding  The sizeHint() is a sensible size, but the
+        widget can be shrunk and still be useful. The widget can make use
+        of extra space, so it should get as much space as possible (e.g.
+        the horizontal direction of a horizontal slider).
+
+    \value MinimumExpanding  The sizeHint() is minimal, and sufficient.
+        The widget can make use of extra space, so it should get as much
+        space as possible (e.g. the horizontal direction of a horizontal
+        slider).

+    \class QSound
+    \brief The QSound class provides access to the platform audio facilities.
+
+    \ingroup multimedia
+
+
+    Qt provides the most commonly required audio operation in GUI
+    applications: asynchronously playing a sound file. This is most
+    easily accomplished using the static play() function:
+
+    \snippet doc/src/snippets/code/src_gui_kernel_qsound.cpp 0
+
+    Alternatively, create a QSound object from the sound file first
+    and then call the play() slot:
+
+    \snippet doc/src/snippets/code/src_gui_kernel_qsound.cpp 1
+
+    Once created a QSound object can be queried for its fileName() and
+    total number of loops() (i.e. the number of times the sound will
+    play). The number of repetitions can be altered using the
+    setLoops() function. While playing the sound, the loopsRemaining()
+    function returns the remaining number of repetitions. Use the
+    isFinished() function to determine whether the sound has finished
+    playing.
+
+    Sounds played using a QSound object may use more memory than the
+    static play() function, but it may also play more immediately
+    (depending on the underlying platform audio facilities). Use the
+    static isAvailable() function to determine whether sound
+    facilities exist on the platform. Which facilities that are
+    actually used varies:
+
+    \table
+    \header \o Platform \o Audio Facility
+    \row
+    \o Microsoft Windows
+    \o The underlying multimedia system is used; only WAVE format sound files
+    are supported.
+    \row
+    \o X11
+    \o The \l{ftp://ftp.x.org/contrib/audio/nas/}{Network Audio System}
+    is used if available, otherwise all operations work silently. NAS
+    supports WAVE and AU files.
+    \row
+    \o Mac OS X
+    \o NSSound is used. All formats that NSSound supports, including QuickTime formats,
+    are supported by Qt for Mac OS X.
+    \row
+    \o Qt for Embedded Linux
+    \o A built-in mixing sound server is used, accessing \c /dev/dsp
+    directly. Only the WAVE format is supported.
+    \row
+    \o Symbian
+    \o CMdaAudioPlayerUtility is used. All formats that Symbian OS or devices support
+    are supported also by Qt.
+    \endtable
+
+    Note that QSound does not support \l{resources.html}{resources}.
+    This might be fixed in a future Qt version.

+    \class QStackedLayout
+
+    \brief The QStackedLayout class provides a stack of widgets where
+    only one widget is visible at a time.
+
+    \ingroup geomanagement
+
+    QStackedLayout can be used to create a user interface similar to
+    the one provided by QTabWidget. There is also a convenience
+    QStackedWidget class built on top of QStackedLayout.
+
+    A QStackedLayout can be populated with a number of child widgets
+    ("pages"). For example:
+
+    \snippet doc/src/snippets/qstackedlayout/main.cpp 0
+    \codeline
+    \snippet doc/src/snippets/qstackedlayout/main.cpp 2
+    \snippet doc/src/snippets/qstackedlayout/main.cpp 3
+
+    QStackedLayout provides no intrinsic means for the user to switch
+    page. This is typically done through a QComboBox or a QListWidget
+    that stores the titles of the QStackedLayout's pages. For
+    example:
+
+    \snippet doc/src/snippets/qstackedlayout/main.cpp 1
+
+    When populating a layout, the widgets are added to an internal
+    list. The indexOf() function returns the index of a widget in that
+    list. The widgets can either be added to the end of the list using
+    the addWidget() function, or inserted at a given index using the
+    insertWidget() function. The removeWidget() function removes the
+    widget at the given index from the layout. The number of widgets
+    contained in the layout, can be obtained using the count()
+    function.
+
+    The widget() function returns the widget at a given index
+    position. The index of the widget that is shown on screen is given
+    by currentIndex() and can be changed using setCurrentIndex(). In a
+    similar manner, the currently shown widget can be retrieved using
+    the currentWidget() function, and altered using the
+    setCurrentWidget() function.
+
+    Whenever the current widget in the layout changes or a widget is
+    removed from the layout, the currentChanged() and widgetRemoved()
+    signals are emitted respectively.
+
+    \sa QStackedWidget, QTabWidget
+*/
+
+/*!
+    \fn void QStackedLayout::currentChanged(int index)
+
+    This signal is emitted whenever the current widget in the layout
+    changes.  The \a index specifies the index of the new current
+    widget, or -1 if there isn't a new one (for example, if there
+    are no widgets in the QStackedLayout)

+    \class QToolTip
+
+    \brief The QToolTip class provides tool tips (balloon help) for any
+    widget.
+
+    \ingroup helpsystem
+
+
+    The tip is a short piece of text reminding the user of the
+    widget's function. It is drawn immediately below the given
+    position in a distinctive black-on-yellow color combination. The
+    tip can be any \l{QTextEdit}{rich text} formatted string.
+
+    Rich text displayed in a tool tip is implicitly word-wrapped unless
+    specified differently with \c{<p style='white-space:pre'>}.
+
+    The simplest and most common way to set a widget's tool tip is by
+    calling its QWidget::setToolTip() function.
+
+    It is also possible to show different tool tips for different
+    regions of a widget, by using a QHelpEvent of type
+    QEvent::ToolTip. Intercept the help event in your widget's \l
+    {QWidget::}{event()} function and call QToolTip::showText() with
+    the text you want to display. The \l{widgets/tooltips}{Tooltips}
+    example illustrates this technique.
+
+    If you are calling QToolTip::hideText(), or QToolTip::showText()
+    with an empty string, as a result of a \l{QEvent::}{ToolTip}-event you
+    should also call \l{QEvent::}{ignore()} on the event, to signal
+    that you don't want to start any tooltip specific modes.
+
+    Note that, if you want to show tooltips in an item view, the
+    model/view architecture provides functionality to set an item's
+    tool tip; e.g., the QTableWidgetItem::setToolTip() function.
+    However, if you want to provide custom tool tips in an item view,
+    you must intercept the help event in the
+    QAbstractItemView::viewportEvent() function and handle it yourself.
+
+    The default tool tip color and font can be customized with
+    setPalette() and setFont(). When a tooltip is currently on
+    display, isVisible() returns true and text() the currently visible
+    text.
+
+    \note Tool tips use the inactive color group of QPalette, because tool
+    tips are not active windows.

+/*!
+    \class QWhatsThis
+    \brief The QWhatsThis class provides a simple description of any
+    widget, i.e. answering the question "What's This?".
+
+    \ingroup helpsystem
+
+
+    "What's This?" help is part of an application's online help
+    system, and provides users with information about the
+    functionality and usage of a particular widget. "What's This?"
+    help texts are typically longer and more detailed than \link
+    QToolTip tooltips\endlink, but generally provide less information
+    than that supplied by separate help windows.
+
+    QWhatsThis provides a single window with an explanatory text that
+    pops up when the user asks "What's This?". The default way for
+    users to ask the question is to move the focus to the relevant
+    widget and press Shift+F1. The help text appears immediately; it
+    goes away as soon as the user does something else.
+    (Note that if there is a shortcut for Shift+F1, this mechanism
+    will not work.) Some dialogs provide a "?" button that users can
+    click to enter "What's This?" mode; they then click the relevant
+    widget to pop up the "What's This?" window. It is also possible to
+    provide a a menu option or toolbar button to switch into "What's
+    This?" mode.
+
+    To add "What's This?" text to a widget or an action, you simply
+    call QWidget::setWhatsThis() or QAction::setWhatsThis().
+
+    The text can be either rich text or plain text. If you specify a
+    rich text formatted string, it will be rendered using the default
+    stylesheet, making it possible to embed images in the displayed
+    text. To be as fast as possible, the default stylesheet uses a
+    simple method to determine whether the text can be rendered as
+    plain text. See Qt::mightBeRichText() for details.
+
+    \snippet doc/src/snippets/whatsthis/whatsthis.cpp 0
+
+    An alternative way to enter "What's This?" mode is to call
+    createAction(), and add the returned QAction to either a menu or
+    a tool bar. By invoking this context help action (in the picture
+    below, the button with the arrow and question mark icon) the user
+    switches into "What's This?" mode. If they now click on a widget
+    the appropriate help text is shown. The mode is left when help is
+    given or when the user presses Esc.
+
+    \img whatsthis.png
+
+    You can enter "What's This?" mode programmatically with
+    enterWhatsThisMode(), check the mode with inWhatsThisMode(), and
+    return to normal mode with leaveWhatsThisMode().
+
+    If you want to control the "What's This?" behavior of a widget
+    manually see Qt::WA_CustomWhatsThis.
+
+    It is also possible to show different help texts for different
+    regions of a widget, by using a QHelpEvent of type
+    QEvent::WhatsThis. Intercept the help event in your widget's
+    QWidget::event() function and call QWhatsThis::showText() with the
+    text you want to display for the position specified in
+    QHelpEvent::pos(). If the text is rich text and the user clicks
+    on a link, the widget also receives a QWhatsThisClickedEvent with
+    the link's reference as QWhatsThisClickedEvent::href(). If a
+    QWhatsThisClickedEvent is handled (i.e. QWidget::event() returns
+    true), the help window remains visible. Call
+    QWhatsThis::hideText() to hide it explicitly.

+    \class QWidget
+    \brief The QWidget class is the base class of all user interface objects.
+
+    \ingroup basicwidgets
+    
+    The widget is the atom of the user interface: it receives mouse, keyboard
+    and other events from the window system, and paints a representation of
+    itself on the screen. Every widget is rectangular, and they are sorted in a
+    Z-order. A widget is clipped by its parent and by the widgets in front of
+    it.
+
+    A widget that is not embedded in a parent widget is called a window.
+    Usually, windows have a frame and a title bar, although it is also possible
+    to create windows without such decoration using suitable
+    \l{Qt::WindowFlags}{window flags}). In Qt, QMainWindow and the various
+    subclasses of QDialog are the most common window types.
+
+    Every widget's constructor accepts one or two standard arguments:
+
+    \list 1
+        \i  \c{QWidget *parent = 0} is the parent of the new widget. If it is 0
+            (the default), the new widget will be a window. If not, it will be
+            a child of \e parent, and be constrained by \e parent's geometry
+            (unless you specify Qt::Window as window flag).
+        \i  \c{Qt::WindowFlags f = 0} (where available) sets the window flags;
+            the default is suitable for almost all widgets, but to get, for
+            example, a window without a window system frame, you must use
+            special flags.
+    \endlist
+
+    QWidget has many member functions, but some of them have little direct
+    functionality; for example, QWidget has a font property, but never uses
+    this itself. There are many subclasses which provide real functionality,
+    such as QLabel, QPushButton, QListWidget, and QTabWidget.
+
+
+    \section1 Top-Level and Child Widgets
+
+    A widget without a parent widget is always an independent window (top-level
+    widget). For these widgets, setWindowTitle() and setWindowIcon() set the
+    title bar and icon respectively.
+
+    Non-window widgets are child widgets, displayed within their parent
+    widgets. Most widgets in Qt are mainly useful as child widgets. For
+    example, it is possible to display a button as a top-level window, but most
+    people prefer to put their buttons inside other widgets, such as QDialog.
+
+    \image parent-child-widgets.png A parent widget containing various child widgets.
+
+    The diagram above shows a QGroupBox widget being used to hold various child
+    widgets in a layout provided by QGridLayout. The QLabel child widgets have
+    been outlined to indicate their full sizes.
+
+    If you want to use a QWidget to hold child widgets you will usually want to
+    add a layout to the parent QWidget. See \l{Layout Management} for more
+    information.
+
+
+    \section1 Composite Widgets
+
+    When a widget is used as a container to group a number of child widgets, it
+    is known as a composite widget. These can be created by constructing a
+    widget with the required visual properties - a QFrame, for example - and
+    adding child widgets to it, usually managed by a layout. The above diagram
+    shows such a composite widget that was created using \l{Qt Designer}.
+
+    Composite widgets can also be created by subclassing a standard widget,
+    such as QWidget or QFrame, and adding the necessary layout and child
+    widgets in the constructor of the subclass. Many of the \l{Qt Examples}
+    {examples provided with Qt} use this approach, and it is also covered in
+    the Qt \l{Tutorials}.
+
+
+    \section1 Custom Widgets and Painting
+
+    Since QWidget is a subclass of QPaintDevice, subclasses can be used to
+    display custom content that is composed using a series of painting
+    operations with an instance of the QPainter class. This approach contrasts
+    with the canvas-style approach used by the \l{Graphics View}
+    {Graphics View Framework} where items are added to a scene by the
+    application and are rendered by the framework itself.
+
+    Each widget performs all painting operations from within its paintEvent()
+    function. This is called whenever the widget needs to be redrawn, either
+    as a result of some external change or when requested by the application.
+
+    The \l{widgets/analogclock}{Analog Clock example} shows how a simple widget
+    can handle paint events.
+
+
+    \section1 Size Hints and Size Policies
+
+    When implementing a new widget, it is almost always useful to reimplement
+    sizeHint() to provide a reasonable default size for the widget and to set
+    the correct size policy with setSizePolicy().
+
+    By default, composite widgets which do not provide a size hint will be
+    sized according to the space requirements of their child widgets.
+
+    The size policy lets you supply good default behavior for the layout
+    management system, so that other widgets can contain and manage yours
+    easily. The default size policy indicates that the size hint represents
+    the preferred size of the widget, and this is often good enough for many
+    widgets.
+
+    \note The size of top-level widgets are constrained to 2/3 of the desktop's
+    height and width. You can resize() the widget manually if these bounds are
+    inadequate.
+
+
+    \section1 Events
+
+    Widgets respond to events that are typically caused by user actions. Qt
+    delivers events to widgets by calling specific event handler functions with
+    instances of QEvent subclasses containing information about each event.
+
+    If your widget only contains child widgets, you probably do not need to
+    implement any event handlers. If you want to detect a mouse click in a
+    child widget call the child's underMouse() function inside the widget's
+    mousePressEvent().
+
+    The \l{widgets/scribble}{Scribble example} implements a wider set of
+    events to handle mouse movement, button presses, and window resizing.
+
+    You will need to supply the behavior and content for your own widgets, but
+    here is a brief overview of the events that are relevant to QWidget,
+    starting with the most common ones:
+
+    \list
+        \i  paintEvent() is called whenever the widget needs to be repainted.
+            Every widget displaying custom content must implement it. Painting
+            using a QPainter can only take place in a paintEvent() or a
+            function called by a paintEvent().
+        \i  resizeEvent() is called when the widget has been resized.
+        \i  mousePressEvent() is called when a mouse button is pressed while
+            the mouse cursor is inside the widget, or when the widget has
+            grabbed the mouse using grabMouse(). Pressing the mouse without
+            releasing it is effectively the same as calling grabMouse().
+        \i  mouseReleaseEvent() is called when a mouse button is released. A
+            widget receives mouse release events when it has received the
+            corresponding mouse press event. This means that if the user
+            presses the mouse inside \e your widget, then drags the mouse
+            somewhere else before releasing the mouse button, \e your widget
+            receives the release event. There is one exception: if a popup menu
+            appears while the mouse button is held down, this popup immediately
+            steals the mouse events.
+        \i  mouseDoubleClickEvent() is called when the user double-clicks in
+            the widget. If the user double-clicks, the widget receives a mouse
+            press event, a mouse release event and finally this event instead
+            of a second mouse press event. (Some mouse move events may also be
+            received if the mouse is not held steady during this operation.) It
+            is \e{not possible} to distinguish a click from a double-click
+            until the second click arrives. (This is one reason why most GUI
+            books recommend that double-clicks be an extension of
+            single-clicks, rather than trigger a different action.)
+    \endlist
+
+    Widgets that accept keyboard input need to reimplement a few more event
+    handlers:
+
+    \list
+        \i  keyPressEvent() is called whenever a key is pressed, and again when
+            a key has been held down long enough for it to auto-repeat. The
+            \key Tab and \key Shift+Tab keys are only passed to the widget if
+            they are not used by the focus-change mechanisms. To force those
+            keys to be processed by your widget, you must reimplement
+            QWidget::event().
+        \i  focusInEvent() is called when the widget gains keyboard focus
+            (assuming you have called setFocusPolicy()). Well-behaved widgets
+            indicate that they own the keyboard focus in a clear but discreet
+            way.
+        \i  focusOutEvent() is called when the widget loses keyboard focus.
+    \endlist
+
+    You may be required to also reimplement some of the less common event
+    handlers:
+
+    \list
+        \i  mouseMoveEvent() is called whenever the mouse moves while a mouse
+            button is held down. This can be useful during drag and drop
+            operations. If you call \l{setMouseTracking()}{setMouseTracking}(true),
+            you get mouse move events even when no buttons are held down.
+            (See also the \l{Drag and Drop} guide.)
+        \i  keyReleaseEvent() is called whenever a key is released and while it
+            is held down (if the key is auto-repeating). In that case, the
+            widget will receive a pair of key release and key press event for
+            every repeat. The \key Tab and \key Shift+Tab keys are only passed
+            to the widget if they are not used by the focus-change mechanisms.
+            To force those keys to be processed by your widget, you must
+            reimplement QWidget::event().
+        \i  wheelEvent() is called whenever the user turns the mouse wheel
+            while the widget has the focus.
+        \i  enterEvent() is called when the mouse enters the widget's screen
+            space. (This excludes screen space owned by any of the widget's
+            children.)
+        \i  leaveEvent() is called when the mouse leaves the widget's screen
+            space. If the mouse enters a child widget it will not cause a
+            leaveEvent().
+        \i  moveEvent() is called when the widget has been moved relative to
+            its parent.
+        \i  closeEvent() is called when the user closes the widget (or when
+            close() is called).
+    \endlist
+
+    There are also some rather obscure events described in the documentation
+    for QEvent::Type. To handle these events, you need to reimplement event()
+    directly.
+
+    The default implementation of event() handles \key Tab and \key Shift+Tab
+    (to move the keyboard focus), and passes on most of the other events to
+    one of the more specialized handlers above.
+
+    Events and the mechanism used to deliver them are covered in 
+    \l{The Event System}.

+    \section1 Widget Style Sheets
+
+    In addition to the standard widget styles for each platform, widgets can
+    also be styled according to rules specified in a \l{styleSheet}
+    {style sheet}. This feature enables you to customize the appearance of
+    specific widgets to provide visual cues to users about their purpose. For
+    example, a button could be styled in a particular way to indicate that it
+    performs a destructive action.
+
+    The use of widget style sheets is described in more detail in the
+    \l{Qt Style Sheets} document.
+
+
+    \section1 Transparency and Double Buffering
+
+    Since Qt 4.0, QWidget automatically double-buffers its painting, so there
+    is no need to write double-buffering code in paintEvent() to avoid
+    flicker.
+
+    Since Qt 4.1, the Qt::WA_ContentsPropagated widget attribute has been
+    deprecated. Instead, the contents of parent widgets are propagated by
+    default to each of their children as long as Qt::WA_PaintOnScreen is not
+    set. Custom widgets can be written to take advantage of this feature by
+    updating irregular regions (to create non-rectangular child widgets), or
+    painting with colors that have less than full alpha component. The
+    following diagram shows how attributes and properties of a custom widget
+    can be fine-tuned to achieve different effects.
+
+    \image propagation-custom.png
+
+    In the above diagram, a semi-transparent rectangular child widget with an
+    area removed is constructed and added to a parent widget (a QLabel showing
+    a pixmap). Then, different properties and widget attributes are set to
+    achieve different effects:
+
+    \list
+        \i  The left widget has no additional properties or widget attributes
+            set. This default state suits most custom widgets using
+            transparency, are irregularly-shaped, or do not paint over their
+            entire area with an opaque brush.
+        \i  The center widget has the \l autoFillBackground property set. This
+            property is used with custom widgets that rely on the widget to
+            supply a default background, and do not paint over their entire
+            area with an opaque brush.
+        \i  The right widget has the Qt::WA_OpaquePaintEvent widget attribute
+            set. This indicates that the widget will paint over its entire area
+            with opaque colors. The widget's area will initially be
+            \e{uninitialized}, represented in the diagram with a red diagonal
+            grid pattern that shines through the overpainted area. The
+            Qt::WA_OpaquePaintArea attribute is useful for widgets that need to
+            paint their own specialized contents quickly and do not need a
+            default filled background.
+    \endlist
+
+    To rapidly update custom widgets with simple background colors, such as
+    real-time plotting or graphing widgets, it is better to define a suitable
+    background color (using setBackgroundRole() with the
+    QPalette::Window role), set the \l autoFillBackground property, and only
+    implement the necessary drawing functionality in the widget's paintEvent().
+
+    To rapidly update custom widgets that constantly paint over their entire
+    areas with opaque content, e.g., video streaming widgets, it is better to
+    set the widget's Qt::WA_OpaquePaintEvent, avoiding any unnecessary overhead
+    associated with repainting the widget's background.
+
+    If a widget has both the Qt::WA_OpaquePaintEvent widget attribute \e{and}
+    the \l autoFillBackground property set, the Qt::WA_OpaquePaintEvent
+    attribute takes precedence. Depending on your requirements, you should
+    choose either one of them.
+
+    Since Qt 4.1, the contents of parent widgets are also propagated to
+    standard Qt widgets. This can lead to some unexpected results if the
+    parent widget is decorated in a non-standard way, as shown in the diagram
+    below.
+
+    \image propagation-standard.png
+
+    The scope for customizing the painting behavior of standard Qt widgets,
+    without resorting to subclassing, is slightly less than that possible for
+    custom widgets. Usually, the desired appearance of a standard widget can be
+    achieved by setting its \l autoFillBackground property.
+
+
+    \section1 Creating Translucent Windows
+
+    Since Qt 4.5, it has been possible to create windows with translucent regions
+    on window systems that support compositing.
+
+    To enable this feature in a top-level widget, set its Qt::WA_TranslucentBackground
+    attribute with setAttribute() and ensure that its background is painted with
+    non-opaque colors in the regions you want to be partially transparent.
+
+    Platform notes:
+
+    \list
+    \o X11: This feature relies on the use of an X server that supports ARGB visuals
+    and a compositing window manager.
+    \o Windows: The widget needs to have the Qt::FramelessWindowHint window flag set
+    for the translucency to work.
+    \endlist
+
+
+    \section1 Native Widgets vs Alien Widgets
+
+    Introduced in Qt 4.4, alien widgets are widgets unknown to the windowing
+    system. They do not have a native window handle associated with them. This
+    feature significantly speeds up widget painting, resizing, and removes flicker.
+
+    Should you require the old behavior with native windows, you can choose
+    one of the following options:
+
+    \list 1
+        \i  Use the \c{QT_USE_NATIVE_WINDOWS=1} in your environment.
+        \i  Set the Qt::AA_NativeWindows attribute on your application. All
+            widgets will be native widgets.
+        \i  Set the Qt::WA_NativeWindow attribute on widgets: The widget itself
+            and all of its ancestors will become native (unless
+            Qt::WA_DontCreateNativeAncestors is set).
+        \i  Call QWidget::winId to enforce a native window (this implies 3).
+        \i  Set the Qt::WA_PaintOnScreen attribute to enforce a native window
+            (this implies 3).
+    \endlist
+
+    \sa QEvent, QPainter, QGridLayout, QBoxLayout
+
+    \section1 Softkeys
+
+    Since Qt 4.6, Softkeys are usually physical keys on a device that have a corresponding label or
+    other visual representation on the screen that is generally located next to its
+    physical counterpart. They are most often found on mobile phone platforms. In
+    modern touch based user interfaces it is also possible to have softkeys that do
+    not correspond to any physical keys. Softkeys differ from other onscreen labels
+    in that they are contextual.
+
+    In Qt, contextual softkeys are added to a widget by calling addAction() and
+    passing a \c QAction with a softkey role set on it. When the widget
+    containing the softkey actions has focus, its softkeys should appear in
+    the user interface. Softkeys are discovered by traversing the widget
+    hierarchy so it is possible to define a single set of softkeys that are
+    present at all times by calling addAction() for a given top level widget.
+
+    On some platforms, this concept overlaps with \c QMenuBar such that if no
+    other softkeys are found and the top level widget is a QMainWindow containing
+    a QMenuBar, the menubar actions may appear on one of the softkeys.
+
+    Note: Currently softkeys are only supported on the Symbian Platform.
+

+    \property QWidget::palette
+    \brief the widget's palette
+
+    This property describes the widget's palette. The palette is used by the
+    widget's style when rendering standard components, and is available as a
+    means to ensure that custom widgets can maintain consistency with the
+    native platform's look and feel. It's common that different platforms, or
+    different styles, have different palettes.
+
+    When you assign a new palette to a widget, the color roles from this
+    palette are combined with the widget's default palette to form the
+    widget's final palette. The palette entry for the widget's background role
+    is used to fill the widget's background (see QWidget::autoFillBackground),
+    and the foreground role initializes QPainter's pen.
+
+    The default depends on the system environment. QApplication maintains a
+    system/theme palette which serves as a default for all widgets.  There may
+    also be special palette defaults for certain types of widgets (e.g., on
+    Windows XP and Vista, all classes that derive from QMenuBar have a special
+    default palette). You can also define default palettes for widgets
+    yourself by passing a custom palette and the name of a widget to
+    QApplication::setPalette(). Finally, the style always has the option of
+    polishing the palette as it's assigned (see QStyle::polish()).
+
+    QWidget propagates explicit palette roles from parent to child. If you
+    assign a brush or color to a specific role on a palette and assign that
+    palette to a widget, that role will propagate to all the widget's
+    children, overriding any system defaults for that role. Note that palettes
+    by default don't propagate to windows (see isWindow()) unless the
+    Qt::WA_WindowPropagation attribute is enabled.
+
+    QWidget's palette propagation is similar to its font propagation.
+
+    The current style, which is used to render the content of all standard Qt
+    widgets, is free to choose colors and brushes from the widget palette, or
+    in some cases, to ignore the palette (partially, or completely). In
+    particular, certain styles like GTK style, Mac style, Windows XP, and
+    Vista style, depend on third party APIs to render the content of widgets,
+    and these styles typically do not follow the palette. Because of this,
+    assigning roles to a widget's palette is not guaranteed to change the
+    appearance of the widget. Instead, you may choose to apply a \l
+    styleSheet. You can refer to our Knowledge Base article
+    \l{http://qt.nokia.com/developer/knowledgebase/22}{here} for more
+    information.
+
+    \warning Do not use this function in conjunction with \l{Qt Style Sheets}.
+    When using style sheets, the palette of a widget can be customized using
+    the "color", "background-color", "selection-color",
+    "selection-background-color" and "alternate-background-color".

+    \property QWidget::updatesEnabled
+    \brief whether updates are enabled
+
+    An updates enabled widget receives paint events and has a system

+    disabled.
+
+    By default, this property is true.
+
+    setUpdatesEnabled() is normally used to disable updates for a
+    short period of time, for instance to avoid screen flicker during
+    large changes. In Qt, widgets normally do not generate screen
+    flicker, but on X11 the server might erase regions on the screen
+    when widgets get hidden before they can be replaced by other
+    widgets. Disabling updates solves this.
+
+    Example:
+    \snippet doc/src/snippets/code/src_gui_kernel_qwidget.cpp 13
+
+    Disabling a widget implicitly disables all its children. Enabling a widget
+    enables all child widgets \e except top-level widgets or those that
+    have been explicitly disabled. Re-enabling updates implicitly calls

+    \brief whether the widget is visible
+
+    Calling setVisible(true) or show() sets the widget to visible
+    status if all its parent widgets up to the window are visible. If
+    an ancestor is not visible, the widget won't become visible until
+    all its ancestors are shown. If its size or position has changed,
+    Qt guarantees that a widget gets move and resize events just
+    before it is shown. If the widget has not been resized yet, Qt
+    will adjust the widget's size to a useful default using
+    adjustSize().
+
+    Calling setVisible(false) or hide() hides a widget explicitly. An
+    explicitly hidden widget will never become visible, even if all
+    its ancestors become visible, unless you show it.
+
+    A widget receives show and hide events when its visibility status
+    changes. Between a hide and a show event, there is no need to
+    waste CPU cycles preparing or displaying information to the user.
+    A video application, for example, might simply stop generating new
+    frames.
+
+    A widget that happens to be obscured by other windows on the
+    screen is considered to be visible. The same applies to iconified
+    windows and windows that exist on another virtual
+    desktop (on platforms that support this concept). A widget
+    receives spontaneous show and hide events when its mapping status
+    is changed by the window system, e.g. a spontaneous hide event
+    when the user minimizes the window, and a spontaneous show event
+    when the window is restored again.
+
+    You almost never have to reimplement the setVisible() function. If
+    you need to change some settings before a widget is shown, use
+    showEvent() instead. If you need to do some delayed initialization

+
+    This event handler can be reimplemented in a subclass to receive paint
+    events passed in \a event.
+
+    A paint event is a request to repaint all or part of a widget. It can
+    happen for one of the following reasons:
+
+    \list
+        \o repaint() or update() was invoked,
+        \o the widget was obscured and has now been uncovered, or
+        \o many other reasons.
+    \endlist
+
+    Many widgets can simply repaint their entire surface when asked to, but
+    some slow widgets need to optimize by painting only the requested region:
+    QPaintEvent::region(). This speed optimization does not change the result,
+    as painting is clipped to that region during event processing. QListView
+    and QTableView do this, for example.
+
+    Qt also tries to speed up painting by merging multiple paint events into
+    one. When update() is called several times or the window system sends
+    several paint events, Qt merges these events into one event with a larger
+    region (see QRegion::united()). The repaint() function does not permit this
+    optimization, so we suggest using update() whenever possible.
+
+    When the paint event occurs, the update region has normally been erased, so
+    you are painting on the widget's background.
+
+    The background can be set using setBackgroundRole() and setPalette().
+
+    Since Qt 4.0, QWidget automatically double-buffers its painting, so there
+    is no need to write double-buffering code in paintEvent() to avoid flicker.
+
+    \bold{Note for the X11 platform}: It is possible to toggle global double
+    buffering by calling \c qt_x11_set_global_double_buffer(). For example,
+
+    \snippet doc/src/snippets/code/src_gui_kernel_qwidget.cpp 14
+
+    \note Generally, you should refrain from calling update() or repaint()
+    \bold{inside} a paintEvent(). For example, calling update() or repaint() on
+    children inside a paintevent() results in undefined behavior; the child may
+    or may not get a paint event.
+
+    \warning If you are using a custom paint engine without Qt's backingstore,
+    Qt::WA_PaintOnScreen must be set. Otherwise, QWidget::paintEngine() will
+    never be called; the backingstore will be used instead.

+/*!
+    \class QWidgetAction
+    \since 4.2
+    \brief The QWidgetAction class extends QAction by an interface
+    for inserting custom widgets into action based containers, such
+    as toolbars.
+
+    \ingroup mainwindow-classes
+
+    Most actions in an application are represented as items in menus or
+    buttons in toolbars. However sometimes more complex widgets are
+    necessary. For example a zoom action in a word processor may be
+    realized using a QComboBox in a QToolBar, presenting a range
+    of different zoom levels. QToolBar provides QToolBar::insertWidget()
+    as convenience function for inserting a single widget.
+    However if you want to implement an action that uses custom
+    widgets for visualization in multiple containers then you have to
+    subclass QWidgetAction.
+
+    If a QWidgetAction is added for example to a QToolBar then
+    QWidgetAction::createWidget() is called. Reimplementations of that
+    function should create a new custom widget with the specified parent.
+
+    If the action is removed from a container widget then
+    QWidgetAction::deleteWidget() is called with the previously created custom
+    widget as argument. The default implementation hides the widget and deletes
+    it using QObject::deleteLater().
+
+    If you have only one single custom widget then you can set it as default
+    widget using setDefaultWidget(). That widget will then be used if the
+    action is added to a QToolBar, or in general to an action container that
+    supports QWidgetAction. If a QWidgetAction with only a default widget is
+    added to two toolbars at the same time then the default widget is shown
+    only in the first toolbar the action was added to. QWidgetAction takes
+    over ownership of the default widget.
+
+    Note that it is up to the widget to activate the action, for example by
+    reimplementing mouse event handlers and calling QAction::trigger().
+
+    \bold {Mac OS X}: If you add a widget to a menu in the application's menu
+    bar on Mac OS X, the widget will be added and it will function but with some
+    limitations:
+    \list 1
+        \o The widget is reparented away from the QMenu to the native menu
+            view. If you show the menu in some other place (e.g. as a popup menu),
+            the widget will not be there.
+        \o Focus/Keyboard handling of the widget is not possible.
+        \o Due to Apple's design, mouse tracking on the widget currently does
+            not work.
+        \o Connecting the triggered() signal to a slot that opens a modal
+            dialog will cause a crash in Mac OS X 10.4 (known bug acknowledged
+            by Apple), a workaround is to use a QueuedConnection instead of a
+            DirectConnection.

+    \class QX11EmbedWidget
+    \ingroup advanced
+
+    \brief The QX11EmbedWidget class provides an XEmbed client widget.
+
+    XEmbed is an X11 protocol that supports the embedding of a widget
+    from one application into another application.
+
+    An XEmbed \e{client widget} is a window that is embedded into a
+    \e container. A container is the graphical location that embeds
+    (or \e swallows) an external application.
+
+    QX11EmbedWidget is a widget used for writing XEmbed applets or
+    plugins. When it has been embedded and the container receives tab
+    focus, focus is passed on to the widget. When the widget reaches
+    the end of its focus chain, focus is passed back to the
+    container. Window activation, accelerator support, modality and
+    drag and drop (XDND) are also handled.
+
+    The widget and container can both initiate the embedding. If the
+    widget is the initiator, the X11 window ID of the container that
+    it wants to embed itself into must be passed to embedInto().
+
+    If the container initiates the embedding, the window ID of the
+    embedded widget must be known. The container calls embed(),
+    passing the window ID.
+
+    This example shows an application that embeds a QX11EmbedWidget
+    subclass into the window whose ID is passed as a command-line
+    argument:
+
+    \snippet doc/src/snippets/qx11embedwidget/main.cpp 0
+
+    The problem of obtaining the window IDs is often solved by the
+    container invoking the application that provides the widget as a
+    separate process (as a panel invokes a docked applet), passing
+    its window ID to the new process as a command-line argument. The
+    new process can then call embedInto() with the container's window
+    ID, as shown in the example code above. Similarly, the new
+    process can report its window ID to the container through IPC, in
+    which case the container can embed the widget.
+
+    When the widget has been embedded, it emits the signal
+    embedded(). If it is closed by the container, the widget emits
+    containerClosed(). If an error occurs when embedding, error() is
+    emitted.
+
+    There are XEmbed widgets available for KDE and GTK+. The GTK+
+    equivalent of QX11EmbedWidget is GtkPlug. The corresponding KDE 3
+    widget is called QXEmbed.
+
+    \sa QX11EmbedContainer, {XEmbed Specification}

+
+/*!
+    \class QX11EmbedContainer
+    \ingroup advanced
+
+    \brief The QX11EmbedContainer class provides an XEmbed container
+    widget.
+
+    XEmbed is an X11 protocol that supports the embedding of a widget
+    from one application into another application.
+
+    An XEmbed \e container is the graphical location that embeds an
+    external \e {client widget}. A client widget is a window that is
+    embedded into a container.
+
+    When a widget has been embedded and the container receives tab
+    focus, focus is passed on to the widget. When the widget reaches
+    the end of its focus chain, focus is passed back to the
+    container. Window activation, accelerator support, modality and
+    drag and drop (XDND) are also handled.
+
+    QX11EmbedContainer is commonly used for writing panels or
+    toolbars that hold applets, or for \e swallowing X11
+    applications. When writing a panel application, one container
+    widget is created on the toolbar, and it can then either swallow
+    another widget using embed(), or allow an XEmbed widget to be
+    embedded into itself. The container's X11 window ID, which is
+    retrieved with winId(), must then be known to the client widget.
+    After embedding, the client's window ID can be retrieved with
+    clientWinId().
+
+    In the following example, a container widget is created as the
+    main widget. It then invokes an application called "playmovie",
+    passing its window ID as a command line argument. The "playmovie"
+    program is an XEmbed client widget. The widget embeds itself into
+    the container using the container's window ID.
+
+    \snippet doc/src/snippets/qx11embedcontainer/main.cpp 0
+
+    When the client widget is embedded, the container emits the
+    signal clientIsEmbedded(). The signal clientClosed() is emitted
+    when a widget is closed.
+
+    It is possible for QX11EmbedContainer to embed XEmbed widgets
+    from toolkits other than Qt, such as GTK+. Arbitrary (non-XEmbed)
+    X11 widgets can also be embedded, but the XEmbed-specific
+    features such as window activation and focus handling are then
+    lost.
+
+    The GTK+ equivalent of QX11EmbedContainer is GtkSocket. The
+    corresponding KDE 3 widget is called QXEmbed.

+
+    This signal is emitted by the client widget when the container

+
+    The container can reject a widget for any reason, but the most
