It can be either a pull-down menu in a menu bar or a standalone context menu. Pull-down menus are shown by the menu bar when the user clicks on the respective item or presses the specified shortcut key. Use QMenuBar::addMenu() to insert a menu into a menu bar. Context menus are usually invoked by some special keyboard key or by right-clicking. They can be executed either asynchronously with popup() or synchronously with exec(). Menus can also be invoked in response to button presses; these are just like context menus except for how they are invoked. \raw HTML

\endraw \section1 Actions A menu consists of a list of action items. Actions are added with the addAction(), addActions() and insertAction() functions. An action is represented vertically and rendered by QStyle. In addition, actions can have a text label, an optional icon drawn on the very left side, and shortcut key sequence such as "Ctrl+X". The existing actions held by a menu can be found with actions(). There are four kinds of action items: separators, actions that show a submenu, widgets, and actions that perform an action. Separators are inserted with addSeparator(), submenus with addMenu(), and all other items are considered action items. When inserting action items you usually specify a receiver and a slot. The receiver will be notifed whenever the item is \l{QAction::triggered()}{triggered()}. In addition, QMenu provides two signals, activated() and highlighted(), which signal the QAction that was triggered from the menu. You clear a menu with clear() and remove individual action items with removeAction(). A QMenu can also provide a tear-off menu. A tear-off menu is a top-level window that contains a copy of the menu. This makes it possible for the user to "tear off" frequently used menus and position them in a convenient place on the screen. If you want this functionality for a particular menu, insert a tear-off handle with setTearOffEnabled(). When using tear-off menus, bear in mind that the concept isn't typically used on Microsoft Windows so some users may not be familiar with it. Consider using a QToolBar instead. Widgets can be inserted into menus with the QWidgetAction class. Instances of this class are used to hold widgets, and are inserted into menus with the addAction() overload that takes a QAction. Conversely, actions can be added to widgets with the addAction(), addActions() and insertAction() functions. \section1 QMenu on Qt for Windows CE If a menu is integrated into the native menubar on Windows Mobile we do not support the signals: aboutToHide (), aboutToShow () and hovered (). It is not possible to display an icon in a native menu on Windows Mobile. \section1 QMenu on Mac OS X with Qt build against Cocoa QMenu can be inserted only once in a menu/menubar. Subsequent insertions will have no effect or will result in a disabled menu item. See the \l{mainwindows/menus}{Menus} example for an example of how to use QMenuBar and QMenu in your application. \bold{Important inherited functions:} addAction(), removeAction(), clear(), addSeparator(), and addMenu(). \sa QMenuBar, {fowler}{GUI Design Handbook: Menu, Drop-Down and Pop-Up}, {Application Example}, {Menus Example}, {Recent Files Example} */ /*!
