The QMenuBar class provides a horizontal menu bar.
A menu bar consists of a list of pull-down menu items. You add menu items with addMenu(). For example, assuming that menubar
is a pointer to a QMenuBar and fileMenu
is a pointer to a QMenu, the following statement inserts the menu into the menu bar:
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.
In most main window style applications you would use the menuBar() function provided in QMainWindow, adding QMenus to the menu bar and adding QActions to the pop-up menus.
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.
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 Alt key is pressed.
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.
CopperSpice 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.
The text used for the application name in the menu bar is obtained from the value set in the Info.plist
file in the application's bundle. Refer to Deploying an Application on Mac OS X for more information.
String Matches | Placement | Notes |
---|---|---|
about* | About <application name> | The Application name is obtained from the Info.plist file, if not found then no About item will appear |
config, options, setup, settings, preferences | Preferences | If not found the Settings item will be disabled |
quit, exit | Quit <application name> | If not found a default Quit item will be created to call QApplication::quit() |
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. If you call QMainWindow::menuBar() to create the shared menu bar, it will only be displayed for the parent QMainWindow. Create a parent-less menu bar as shown below.
|
explicit |
Constructs a menu bar with the given parent.
QMenuBar::~QMenuBar | ( | ) |
Destroys the menu bar.
Returns the QAction at point. Returns nullptr if there is no action at point or if the location has a separator.
|
overrideprotectedvirtual |
Reimplemented from QWidget::actionEvent().
Reimplemented from QWidget.
Returns the geometry of action as a QRect.
QAction * QMenuBar::activeAction | ( | ) | const |
Returns the QAction that is currently highlighted. A null pointer will be returned if no action is currently selected.
This convenience function creates a new action with text. The function adds the newly created action to the menu's list of actions, and returns it.
QAction * QMenuBar::addAction | ( | const QString & | text, |
const QObject * | receiver, | ||
const QString & | member | ||
) |
This convenience function creates a new action with the given text. The action's triggered() signal is connected to the receiver's member slot. The function adds the newly created action to the menu's list of actions and returns it.
|
using |
Appends action to the list of existing actions available for this widget. A QAction list is typically used to create a context QMenu, however it can be represented in different ways depending on the widget.
A QWidget should only have one of each action. Adding an action which already exists will not cause the same action to be in the widget multiple times. The ownership of action is not transferred to this QWidget.
Appends a new QMenu with icon and title to the menu bar. The menu bar takes ownership of the menu. Returns the new menu.
Appends a new QMenu with title to the menu bar. The menu bar takes ownership of the menu. Returns the new menu.
Appends menu to the menu bar. Returns the menu's menuAction().
QAction * QMenuBar::addSeparator | ( | ) |
Appends a separator to the menu.
|
overrideprotectedvirtual |
Reimplemented from QWidget::changeEvent().
Reimplemented from QWidget.
void QMenuBar::clear | ( | ) |
Removes all the actions from the menu bar.
QWidget * QMenuBar::cornerWidget | ( | Qt::Corner | corner = Qt::TopRightCorner | ) | const |
Returns the widget on the left of the first or on the right of the last menu item, depending on corner. Using a corner other than Qt::TopRightCorner or Qt::TopLeftCorner will result in a warning.

signal |
This signal is emitted when a menu action is highlighted, action is the action that caused the event to be sent. This is used to update status information.
|
protected |
Initialize option with the values from the menu bar and information from action. This method is useful for subclasses when they need a QStyleOptionMenuItem, but do not want to fill in all the information themselves.
Inserts menu before action before and returns the menus menuAction().
Inserts a newly created action into this menu bar's list of actions before action before and returns a pointer to the QAction. This new action will return true if QAction::isSeparator() is called.

This sets the given widget to be shown directly on the left of the first menu item, or on the right of the last menu item, depending on corner.
The menu bar takes ownership of widget, reparenting it into the menu bar. However, if the corner already contains a widget, this previous widget will no longer be managed and will still be a visible child of the menu bar.
Using a corner other than Qt::TopRightCorner or Qt::TopLeftCorner will result in a warning.

signal |
This signal is emitted when an action in a menu belonging to this menubar is triggered as a result of a mouse click, action is the action that caused the signal to be emitted.
Normally, you connect each menu action to a single slot using QAction::triggered(), but sometimes you will want to connect several items to a single slot (most often if the user selects from an array). This signal is useful in such cases.

This property holds whether or not a menubar will be used as a native menubar on platforms that support it. This is currently supported only on Mac OS X.
If this property is true the menubar is used in the native menubar and is not in the window of its parent, if false the menubar remains in the window. On other platforms setting this attribute has no effect and reading the attribute will return false.
The default for this property is based on the Qt::AA_DontUseNativeMenuBar attribute in QApplication. Explicitly setting this property overrides the presence (or absence) of the attribute.
