By default, these styles are built - into the QtGui library. Styles can also be made available as - plugins. - - Qt's built-in widgets use QStyle to perform nearly all of their - drawing, ensuring that they look exactly like the equivalent - native widgets. The diagram below shows a QComboBox in eight - different styles. - - \img qstyle-comboboxes.png Eight combo boxes - - Topics: - - \tableofcontents - - \section1 Setting a Style - - The style of the entire application can be set using the - QApplication::setStyle() function. It can also be specified by the - user of the application, using the \c -style command-line option: - - \snippet doc/src/snippets/code/src_gui_styles_qstyle.cpp 0 - - If no style is specified, Qt will choose the most appropriate - style for the user's platform or desktop environment. - - A style can also be set on an individual widget using the - QWidget::setStyle() function. - - \section1 Developing Style-Aware Custom Widgets - - If you are developing custom widgets and want them to look good on - all platforms, you can use QStyle functions to perform parts of - the widget drawing, such as drawItemText(), drawItemPixmap(), - drawPrimitive(), drawControl(), and drawComplexControl(). - - Most QStyle draw functions take four arguments: - \list - \o an enum value specifying which graphical element to draw - \o a QStyleOption specifying how and where to render that element - \o a QPainter that should be used to draw the element - \o a QWidget on which the drawing is performed (optional) - \endlist - - For example, if you want to draw a focus rectangle on your - widget, you can write: - - \snippet doc/src/snippets/styles/styles.cpp 1 - - QStyle gets all the information it needs to render the graphical - element from QStyleOption. The widget is passed as the last - argument in case the style needs it to perform special effects - (such as animated default buttons on Mac OS X), but it isn't - mandatory. In fact, you can use QStyle to draw on any paint - device, not just widgets, by setting the QPainter properly. - - QStyleOption has various subclasses for the various types of - graphical elements that can be drawn. For example, - PE_FrameFocusRect expects a QStyleOptionFocusRect argument. - - To ensure that drawing operations are as fast as possible, - QStyleOption and its subclasses have public data members. See the - QStyleOption class documentation for details on how to use it. - - For convenience, Qt provides the QStylePainter class, which - combines a QStyle, a QPainter, and a QWidget. This makes it - possible to write - - \snippet doc/src/snippets/styles/styles.cpp 5 - \dots - \snippet doc/src/snippets/styles/styles.cpp 7 - - instead of - - \snippet doc/src/snippets/styles/styles.cpp 2 - \dots - \snippet doc/src/snippets/styles/styles.cpp 3 - - \section1 Creating a Custom Style - - You can create a custom look and feel for your application by - creating a custom style. There are two approaches to creating a - custom style. In the static approach, you either choose an - existing QStyle class, subclass it, and reimplement virtual - functions to provide the custom behavior, or you create an entire - QStyle class from scratch. In the dynamic approach, you modify the - behavior of your system style at runtime. The static approach is - described below. The dynamic approach is described in QProxyStyle. - - The first step in the static approach is to pick one of the styles - provided by Qt from which you will build your custom style. Your - choice of QStyle class will depend on which style resembles your - desired style the most. The most general class that you can use as - a base is QCommonStyle (not QStyle). This is because Qt requires - its styles to be \l{QCommonStyle}s. - - Depending on which parts of the base style you want to change, - you must reimplement the functions that are used to draw those - parts of the interface. To illustrate this, we will modify the - look of the spin box arrows drawn by QWindowsStyle. The arrows - are \e{primitive elements} that are drawn by the drawPrimitive() - function, so we need to reimplement that function. We need the - following class declaration: - - \snippet doc/src/snippets/customstyle/customstyle.h 0 - - To draw its up and down arrows, QSpinBox uses the - PE_IndicatorSpinUp and PE_IndicatorSpinDown primitive elements. - Here's how to reimplement the drawPrimitive() function to draw - them differently: - - \snippet doc/src/snippets/customstyle/customstyle.cpp 2 - \snippet doc/src/snippets/customstyle/customstyle.cpp 3 - \snippet doc/src/snippets/customstyle/customstyle.cpp 4 - - Notice that we don't use the \c widget argument, except to pass it - on to the QWindowStyle::drawPrimitive() function. As mentioned - earlier, the information about what is to be drawn and how it - should be drawn is specified by a QStyleOption object, so there is - no need to ask the widget. - - If you need to use the \c widget argument to obtain additional - information, be careful to ensure that it isn't 0 and that it is - of the correct type before using it. For example: - - \snippet doc/src/snippets/customstyle/customstyle.cpp 0 - \dots - \snippet doc/src/snippets/customstyle/customstyle.cpp 1 - - When implementing a custom style, you cannot assume that the - widget is a QSpinBox just because the enum value is called - PE_IndicatorSpinUp or PE_IndicatorSpinDown. - - The documentation for the \l{widgets/styles}{Styles} example - covers this topic in more detail. - - \warning Qt style sheets are currently not supported for custom QStyle - subclasses. We plan to address this in some future release. - - - \section1 Using a Custom Style - - There are several ways of using a custom style in a Qt - application. The simplest way is to pass the custom style to the - QApplication::setStyle() static function before creating the - QApplication object: - - \snippet snippets/customstyle/main.cpp using a custom style - - You can call QApplication::setStyle() at any time, but by calling - it before the constructor, you ensure that the user's preference, - set using the \c -style command-line option, is respected. - - You may want to make your custom style available for use in other - applications, which may not be yours and hence not available for - you to recompile. The Qt Plugin system makes it possible to create - styles as plugins. Styles created as plugins are loaded as shared - objects at runtime by Qt itself. Please refer to the \link - plugins-howto.html Qt Plugin\endlink documentation for more - information on how to go about creating a style plugin. - - Compile your plugin and put it into Qt's \c plugins/styles - directory. We now have a pluggable style that Qt can load - automatically. To use your new style with existing applications, - simply start the application with the following argument: - - \snippet doc/src/snippets/code/src_gui_styles_qstyle.cpp 1 - - The application will use the look and feel from the custom style you - implemented. - - \section1 Right-to-Left Desktops - - Languages written from right to left (such as Arabic and Hebrew) - usually also mirror the whole layout of widgets, and require the - light to come from the screen's top-right corner instead of - top-left. - - If you create a custom style, you should take special care when - drawing asymmetric elements to make sure that they also look - correct in a mirrored layout. An easy way to test your styles is - to run applications with the \c -reverse command-line option or - to call QApplication::setLayoutDirection() in your \c main() - function. - - Here are some things to keep in mind when making a style work well in a - right-to-left environment: - - \list - \o subControlRect() and subElementRect() return rectangles in screen coordinates - \o QStyleOption::direction indicates in which direction the item should be drawn in - \o If a style is not right-to-left aware it will display items as if it were left-to-right - \o visualRect(), visualPos(), and visualAlignment() are helpful functions that will - translate from logical to screen representations. - \o alignedRect() will return a logical rect aligned for the current direction - \endlist - - \section1 Styles in Item Views - - The painting of items in views is performed by a delegate. Qt's - default delegate, QStyledItemDelegate, is also used for for calculating bounding - rectangles of items, and their sub-elements for the various kind - of item \l{Qt::ItemDataRole}{data roles} - QStyledItemDelegate supports. See the QStyledItemDelegate class - description to find out which datatypes and roles are supported. You - can read more about item data roles in \l{Model/View Programming}. - - When QStyledItemDelegate paints its items, it draws - CE_ItemViewItem, and calculates their size with CT_ItemViewItem. - Note also that it uses SE_ItemViewItemText to set the size of - editors. When implementing a style to customize drawing of item - views, you need to check the implementation of QCommonStyle (and - any other subclasses from which your style - inherits). This way, you find out which and how - other style elements are painted, and you can then reimplement the - painting of elements that should be drawn differently. - - We include a small example where we customize the drawing of item - backgrounds. - - \snippet doc/src/snippets/customviewstyle.cpp 0 - - The primitive element PE_PanelItemViewItem is responsible for - painting the background of items, and is called from - \l{QCommonStyle}'s implementation of CE_ItemViewItem. - - To add support for drawing of new datatypes and item data roles, - it is necessary to create a custom delegate. But if you only - need to support the datatypes implemented by the default - delegate, a custom style does not need an accompanying - delegate. The QStyledItemDelegate class description gives more - information on custom delegates. - - The drawing of item view headers is also done by the style, giving - control over size of header items and row and column sizes. - - \sa QStyleOption, QStylePainter, {Styles Example}, - {Styles and Style Aware Widgets}, QStyledItemDelegate -*/ - -/*! - Constructs a style object. -*/ -QStyle::QStyle() - : QObject(*new QStylePrivate) -{ - Q_D(QStyle); - d->proxyStyle = this; -} - -/*! - \internal - - Constructs a style object. -*/ -QStyle::QStyle(QStylePrivate &dd) - : QObject(dd) -{ - Q_D(QStyle); - d->proxyStyle = this; -} - -/*! - Destroys the style object. -*/ -QStyle::~QStyle() -{ -} - -/*! - Initializes the appearance of the given \a widget. - - This function is called for every widget at some point after it - has been fully created but just \e before it is shown for the very - first time. - - Note that the default implementation does nothing. Reasonable - actions in this function might be to call the - QWidget::setBackgroundMode() function for the widget. Do not use - the function to set, for example, the geometry. Reimplementing - this function provides a back-door through which the appearance - of a widget can be changed, but with Qt's style engine it is - rarely necessary to implement this function; reimplement - drawItemPixmap(), drawItemText(), drawPrimitive(), etc. instead. - - The QWidget::inherits() function may provide enough information to - allow class-specific customizations. But because new QStyle - subclasses are expected to work reasonably with all current and \e - future widgets, limited use of hard-coded customization is - recommended. - - \sa unpolish() -*/ -void QStyle::polish(QWidget * /* widget */) -{ -} - -/*! - Uninitialize the given \a{widget}'s appearance. - - This function is the counterpart to polish(). It is called for - every polished widget whenever the style is dynamically changed; - the former style has to unpolish its settings before the new style - can polish them again. - - Note that unpolish() will only be called if the widget is - destroyed. This can cause problems in some cases, e.g, if you - remove a widget from the UI, cache it, and then reinsert it after - the style has changed; some of Qt's classes cache their widgets. - - \sa polish() -*/ -void QStyle::unpolish(QWidget * /* widget */) -{ -} - -/*! - \fn void QStyle::polish(QApplication * application) - \overload - - Late initialization of the given \a application object. -*/ -void QStyle::polish(QApplication * /* app */) -{ -} - -/*! - \fn void QStyle::unpolish(QApplication * application) - \overload - - Uninitialize the given \a application. -*/ -void QStyle::unpolish(QApplication * /* app */) -{ -} - -/*! - \fn void QStyle::polish(QPalette & palette) - \overload - - Changes the \a palette according to style specific requirements - for color palettes (if any). - - \sa QPalette, QApplication::setPalette() -*/ -void QStyle::polish(QPalette & /* pal */) -{ -} - -/*! - \fn QRect QStyle::itemTextRect(const QFontMetrics &metrics, const QRect &rectangle, int alignment, bool enabled, const QString &text) const - - Returns the area within the given \a rectangle in which to draw - the provided \a text according to the specified font \a metrics - and \a alignment.
