You add - menu items with addMenu(). For example, asuming that \c menubar - is a pointer to a QMenuBar and \c fileMenu is a pointer to a - QMenu, the following statement inserts the menu into the menu bar: - \snippet doc/src/snippets/code/src_gui_widgets_qmenubar.cpp 0 - - The ampersand in the menu item's text sets Alt+F as a shortcut for - this menu. (You can use "\&\&" to get a real ampersand in the menu - bar.) - - There is no need to lay out a menu bar. It automatically sets its - own geometry to the top of the parent widget and changes it - appropriately whenever the parent is resized. - - \section1 Usage - - In most main window style applications you would use the - \l{QMainWindow::}{menuBar()} function provided in QMainWindow, - adding \l{QMenu}s to the menu bar and adding \l{QAction}s to the - pop-up menus. - - Example (from the \l{mainwindows/menus}{Menus} example): - - \snippet examples/mainwindows/menus/mainwindow.cpp 9 - - Menu items may be removed with removeAction(). - - Widgets can be added to menus by using instances of the QWidgetAction - class to hold them. These actions can then be inserted into menus - in the usual way; see the QMenu documentation for more details. - - \section1 Platform Dependent Look and Feel - - Different platforms have different requirements for the appearance - of menu bars and their behavior when the user interacts with them. - For example, Windows systems are often configured so that the - underlined character mnemonics that indicate keyboard shortcuts - for items in the menu bar are only shown when the \gui{Alt} key is - pressed. - - \table - - \row \o \inlineimage plastique-menubar.png A menu bar shown in the - Plastique widget style. - - \o The \l{QPlastiqueStyle}{Plastique widget style}, like most - other styles, handles the \gui{Help} menu in the same way as it - handles any other menu. - - \row \o \inlineimage motif-menubar.png A menu bar shown in the - Motif widget style. - - \o The \l{QMotifStyle}{Motif widget style} treats \gui{Help} menus - in a special way, placing them at right-hand end of the menu bar. - - \endtable - - \section1 QMenuBar on Mac OS X - - QMenuBar on Mac OS X is a wrapper for using the system-wide menu bar. - If you have multiple menu bars in one dialog the outermost menu bar - (normally inside a widget with widget flag Qt::Window) will - be used for the system-wide menu bar. - - Qt for Mac OS X also provides a menu bar merging feature to make - QMenuBar conform more closely to accepted Mac OS X menu bar layout. - The merging functionality is based on string matching the title of - a QMenu entry. These strings are translated (using QObject::tr()) - in the "QMenuBar" context. If an entry is moved its slots will still - fire as if it was in the original place. The table below outlines - the strings looked for and where the entry is placed if matched: - - \table - \header \i String matches \i Placement \i Notes - \row \i about.* - \i Application Menu | About <application name> - \i The application name is fetched from the \c {Info.plist} file - (see note below). If this entry is not found no About item - will appear in the Application Menu. - \row \i config, options, setup, settings or preferences - \i Application Menu | Preferences - \i If this entry is not found the Settings item will be disabled - \row \i quit or exit - \i Application Menu | Quit <application name> - \i If this entry is not found a default Quit item will be - created to call QApplication::quit() - \endtable - - You can override this behavior by using the QAction::menuRole() - property. - - If you want all windows in a Mac application to share one menu - bar, you must create a menu bar that does not have a parent. - Create a parent-less menu bar this way: - - \snippet doc/src/snippets/code/src_gui_widgets_qmenubar.cpp 1 - - \bold{Note:} Do \e{not} call QMainWindow::menuBar() to create the - shared menu bar, because that menu bar will have the QMainWindow - as its parent. That menu bar would only be displayed for the - parent QMainWindow. - - \bold{Note:} The text used for the application name in the menu - bar is obtained from the value set in the \c{Info.plist} file in - the application's bundle. See \l{Deploying an Application on - Mac OS X} for more information. - - \section1 QMenuBar on Windows CE - - QMenuBar on Windows CE is a wrapper for using the system-wide menu bar, - similar to the Mac. This feature is activated for Windows Mobile - and integrates QMenuBar with the native soft keys. The left soft - key can be controlled with QMenuBar::setDefaultAction() and the - right soft key can be used to access the menu bar. - - The hovered() signal is not supported for the native menu - integration. Also, it is not possible to display an icon in a - native menu on Windows Mobile. - - \section1 Examples - - The \l{mainwindows/menus}{Menus} example shows how to use QMenuBar - and QMenu. The other \l{Main Window Examples}{main window - application examples} also provide menus using these classes. - - \sa QMenu, QShortcut, QAction, - {http://developer.apple.com/documentation/UserExperience/Conceptual/AppleHIGuidelines/XHIGIntro/XHIGIntro.html}{Introduction to Apple Human Interface Guidelines}, - {fowler}{GUI Design Handbook: Menu Bar}, {Menus Example} -*/ - - -void QMenuBarPrivate::init() -{ - Q_Q(QMenuBar); - q->setSizePolicy(QSizePolicy::MinimumExpanding, QSizePolicy::Minimum); - q->setAttribute(Qt::WA_CustomWhatsThis); -#ifdef Q_WS_MAC - macCreateMenuBar(q->parentWidget()); - if(mac_menubar) - q->hide(); -#endif -#ifdef Q_WS_WINCE - if (qt_wince_is_mobile()) { - wceCreateMenuBar(q->parentWidget()); - if(wce_menubar) - q->hide(); - } - else { - QApplication::setAttribute(Qt::AA_DontUseNativeMenuBar, true); - } -#endif - q->setBackgroundRole(QPalette::Button); - oldWindow = oldParent = 0; -#ifdef QT3_SUPPORT - doAutoResize = false; -#endif -#ifdef QT_SOFTKEYS_ENABLED - menuBarAction = 0; -#endif - handleReparent(); - q->setMouseTracking(q->style()->styleHint(QStyle::SH_MenuBar_MouseTracking, 0, q)); - - extension = new QMenuBarExtension(q); - extension->setFocusPolicy(Qt::NoFocus); - extension->hide(); -} - -//Gets the next action for keyboard navigation -QAction *QMenuBarPrivate::getNextAction(const int _start, const int increment) const -{ - Q_Q(const QMenuBar); - const_cast<QMenuBarPrivate*>(this)->updateGeometries(); - bool allowActiveAndDisabled = q->style()->styleHint(QStyle::SH_Menu_AllowActiveAndDisabled, 0, q); - const int start = (_start == -1 && increment == -1) ? actions.count() : _start; - const int end = increment == -1 ? 0 : actions.count() - 1; - - for (int i = start; i != end;) { - i += increment; - QAction *current = actions.at(i); - if (!actionRects.at(i).isNull() && (allowActiveAndDisabled || current->isEnabled())) - return current; - } - - if (_start != -1) //let's try from the beginning or the end - return getNextAction(-1, increment); - - return 0; -} - -/*! - Constructs a menu bar with parent \a parent. -*/ -QMenuBar::QMenuBar(QWidget *parent) : QWidget(*new QMenuBarPrivate, parent, 0) -{ - Q_D(QMenuBar); - d->init(); -} - -#ifdef QT3_SUPPORT -/*! - Use one of the constructors that doesn't take the \a name - argument and then use setObjectName() instead. -*/ -QMenuBar::QMenuBar(QWidget *parent, const char *name) : QWidget(*new QMenuBarPrivate, parent, 0) -{ - Q_D(QMenuBar); - d->init(); - setObjectName(QString::fromAscii(name)); -} -#endif - -/*! - Destroys the menu bar. -*/ -QMenuBar::~QMenuBar() -{ -#ifdef Q_WS_MAC - Q_D(QMenuBar); - d->macDestroyMenuBar(); -#endif -#ifdef Q_WS_WINCE - Q_D(QMenuBar); - if (qt_wince_is_mobile()) - d->wceDestroyMenuBar(); -#endif -#ifdef Q_WS_S60 - Q_D(QMenuBar); - d->symbianDestroyMenuBar(); -#endif -} - -/*! - \overload - - This convenience function creates a new action with \a text. - The function adds the newly created action to the menu's - list of actions, and returns it. - - \sa QWidget::addAction(), QWidget::actions() -*/ -QAction *QMenuBar::addAction(const QString &text) -{ - QAction *ret = new QAction(text, this); - addAction(ret); - return ret; -} - -/*! - \overload - - This convenience function creates a new action with the given \a - text.
