The QMenu class provides a menu widget for use in menu bars, context menus, and other popup menus.
A menu widget is a selection menu. 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.

Fig. A menu shown in Plastique Style Widget Gallery{Plastique widget style}, Windows XP Style Widget Gallery{Windows XP widget style}, and Macintosh Style Widget Gallery{Macintosh widget style}.
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 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.
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.
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 Menus example for an example of how to use QMenuBar and QMenu in your application.
Important inherited functions: addAction(), removeAction(), clear(), addSeparator(), and addMenu().

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.Executes this menu synchronously.
Pops up the menu so that the action action will be at the specified global position p. To translate a widget's local coordinates into global coordinates, use QWidget::mapToGlobal().
This returns the triggered QAction in either the popup menu or one of its submenus, or 0 if no item was triggered (normally because the user pressed Esc).
Note that all signals are emitted as usual. If you connect a QAction to a slot and call the menu's exec(), you get the result both via the signal-slot connection and in the return value of exec().
Common usage is to position the menu at the current mouse position:
or aligned to a widget:
or in reaction to a QMouseEvent *e:
When positioning a menu with exec() or popup(), bear in mind that you cannot rely on the menu's current size(). For performance reasons, the menu adapts its size only when necessary. So in many cases, the size before and after the show is different. Instead, use sizeHint() which calculates the proper size depending on the menu's current contents.

This function will return the OSMenuRef used to create the native menu bar bindings.
If Qt is built against Carbon, the OSMenuRef is a MenuRef that can be used with Carbon's Menu Manager API.
If Qt is built against Cocoa, the OSMenuRef is a NSMenu pointer.

Displays the menu so that the action atAction will be at the specified global position p.
Use popup() on the relevant QAction instead.
To translate a widget's local coordinates into global coordinates, use QWidget::mapToGlobal().
When positioning a menu with exec() or popup(), bear in mind that you cannot rely on the menu's current size(). For performance reasons, the menu adapts its size only when necessary, so in many cases, the size before and after the show is different. Instead, use sizeHint() which calculates the proper size depending on the menu's current contents.

signal |
This signal is emitted when an action in this menu is triggered.
action is the action that caused the signal to be emitted.
Normally, you connect each menu action's QAction::triggered() signal to its own custom slot, but sometimes you will want to connect several actions to a single slot, for example, when you have a group of closely related actions, such as "left justify", "center", "right justify".

The icon of the menu.
This is equivalent to the QAction::icon property of the menuAction().
By default, if no icon is explicitly set, this property contains a null icon.
|
private |
whether consecutive separators should be collapsed
This property specifies whether consecutive separators in the menu should be visually collapsed to a single one. Separators at the beginning or the end of the menu are also hidden.
By default, this property is true.
|
private |
whether the menu supports being torn off
When true, the menu contains a special tear-off item (often shown as a dashed line at the top of the menu) that creates a copy of the menu when it is triggered.
This "torn-off" copy lives in a separate window. It contains the same menu items as the original menu, with the exception of the tear-off handle.
By default, this property is false.

private |
The title of the menu.
This is equivalent to the QAction::text property of the menuAction().
By default, this property contains an empty string.
