\class QMenuBar
\brief The QMenuBar class provides a horizontal menu bar.
\ingroup application
\mainclass
A menu bar consists of a list of pull-down menu items. 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:
\code
menubar->addMenu(fileMenu);
\endcode
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.
\omit
Example of creating a menu bar with menu items (from \l menu/menu.cpp):
\quotefile menu/menu.cpp
\skipto file = new QMenu
\printline
\skipto Qt::Key_O
\printline
\printline
\skipto new QMenuBar
\printline
\skipto addMenu
\printline
\endomit
In most main window style applications you would use the menuBar()
provided in QMainWindow, adding \l{QMenu}s to the menu bar and
adding \l{QAction}s to the popup menus.
Example (from the \l{mainwindows/menus}{Menus} example):
\quotefile mainwindows/menus/mainwindow.cpp
\skipto fileMenu =
\printuntil fileMenu->addAction(
Menu items may be removed with removeAction().
\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 menubar 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 menubar 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 Qt/Mac
QMenuBar on Qt/Mac is a wrapper for using the system-wide menubar.
If you have multiple menubars in one dialog the outermost menubar
(normally inside a widget with widget flag Qt::Window) will
be used for the system-wide menubar.
Qt/Mac also provides a menubar merging feature to make QMenuBar
conform more closely to accepted Mac OS X menubar 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 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.
\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 Qt/Mac} for more information.
\section1 Examples
The \l{mainwindows/menus}{Menus} example shows how to use QMenuBar and QMenu.
The other \l{Qt Examples#Main Window Examples}{main window application examples}
also provide menus using these classes.
