| 76 | \class QMenuBar qmenubar.h
|
---|
| 77 | \brief The QMenuBar class provides a horizontal menu bar.
|
---|
| 78 |
|
---|
| 79 | \ingroup application
|
---|
| 80 | \mainclass
|
---|
| 81 |
|
---|
| 82 | A menu bar consists of a list of pull-down menu items. You add
|
---|
| 83 | menu items with \link QMenuData::insertItem()
|
---|
| 84 | insertItem()\endlink. For example, asuming that \c menubar is a
|
---|
| 85 | pointer to a QMenuBar and \c filemenu is a pointer to a
|
---|
| 86 | QPopupMenu, the following statement inserts the menu into the menu
|
---|
| 87 | bar:
|
---|
| 88 | \code
|
---|
| 89 | menubar->insertItem( "&File", filemenu );
|
---|
| 90 | \endcode
|
---|
| 91 | The ampersand in the menu item's text sets Alt+F as a shortcut for
|
---|
| 92 | this menu. (You can use "\&\&" to get a real ampersand in the menu
|
---|
| 93 | bar.)
|
---|
| 94 |
|
---|
| 95 | Items are either enabled or disabled. You toggle their state with
|
---|
| 96 | setItemEnabled().
|
---|
| 97 |
|
---|
| 98 | There is no need to lay out a menu bar. It automatically sets its
|
---|
| 99 | own geometry to the top of the parent widget and changes it
|
---|
| 100 | appropriately whenever the parent is resized.
|
---|
| 101 |
|
---|
| 102 | \important insertItem removeItem clear insertSeparator setItemEnabled isItemEnabled setItemVisible isItemVisible
|
---|
| 103 |
|
---|
| 104 | Example of creating a menu bar with menu items (from \l menu/menu.cpp):
|
---|
| 105 | \quotefile menu/menu.cpp
|
---|
| 106 | \skipto file = new QPopupMenu
|
---|
| 107 | \printline
|
---|
| 108 | \skipto Key_O
|
---|
| 109 | \printline
|
---|
| 110 | \printline
|
---|
| 111 | \skipto new QMenuBar
|
---|
| 112 | \printline
|
---|
| 113 | \skipto insertItem
|
---|
| 114 | \printline
|
---|
| 115 |
|
---|
| 116 | In most main window style applications you would use the menuBar()
|
---|
| 117 | provided in QMainWindow, adding \l{QPopupMenu}s to the menu bar
|
---|
| 118 | and adding \l{QAction}s to the popup menus.
|
---|
| 119 |
|
---|
| 120 | Example (from \l action/application.cpp):
|
---|
| 121 | \quotefile action/application.cpp
|
---|
| 122 | \skipto file = new QPopupMenu
|
---|
| 123 | \printuntil fileNewAction
|
---|
| 124 |
|
---|
| 125 | Menu items can have text and pixmaps (or iconsets), see the
|
---|
| 126 | various \link QMenuData::insertItem() insertItem()\endlink
|
---|
| 127 | overloads, as well as separators, see \link
|
---|
| 128 | QMenuData::insertSeparator() insertSeparator()\endlink. You can
|
---|
| 129 | also add custom menu items that are derived from
|
---|
| 130 | \l{QCustomMenuItem}.
|
---|
| 131 |
|
---|
| 132 | Menu items may be removed with removeItem() and enabled or
|
---|
| 133 | disabled with \link QMenuData::setItemEnabled()
|
---|
| 134 | setItemEnabled()\endlink.

| 138 | \section1 QMenuBar on Qt/Mac
|
---|
| 139 |
|
---|
| 140 | QMenuBar on Qt/Mac is a wrapper for using the system-wide menubar.
|
---|
| 141 | If you have multiple menubars in one dialog the outermost menubar
|
---|
| 142 | (normally inside a widget with widget flag \c WType_TopLevel) will
|
---|
| 143 | be used for the system-wide menubar.
|
---|
| 144 |
|
---|
| 145 | Note that arbitrary Qt widgets \e cannot be inserted into a
|
---|
| 146 | QMenuBar on the Mac because Qt uses Mac's native menus which don't
|
---|
| 147 | support this functionality. This limitation does not apply to
|
---|
| 148 | stand-alone QPopupMenus.
|
---|
| 149 |
|
---|
| 150 | Qt/Mac also provides a menubar merging feature to make QMenuBar
|
---|
| 151 | conform more closely to accepted Mac OS X menubar layout. The
|
---|
| 152 | merging functionality is based on string matching the title of a
|
---|
| 153 | QPopupMenu entry. These strings are translated (using
|
---|
| 154 | QObject::tr()) in the "QMenuBar" context. If an entry is moved its
|
---|
| 155 | slots will still fire as if it was in the original place. The
|
---|
| 156 | table below outlines the strings looked for and where the entry is
|
---|
| 157 | placed if matched:
|
---|
| 158 |
|
---|
| 159 | \table
|
---|
| 160 | \header \i String matches \i Placement \i Notes
|
---|
| 161 | \row \i about.*
|
---|
| 162 | \i Application Menu | About <application name>
|
---|
| 163 | \i If this entry is not found no About item will appear in
|
---|
| 164 | the Application Menu
|
---|
| 165 | \row \i config, options, setup, settings or preferences
|
---|
| 166 | \i Application Menu | Preferences
|
---|
| 167 | \i If this entry is not found the Settings item will be disabled
|
---|
| 168 | \row \i quit or exit
|
---|
| 169 | \i Application Menu | Quit <application name>
|
---|
| 170 | \i If this entry is not found a default Quit item will be
|
---|
| 171 | created to call QApplication::quit()
|
---|
| 172 | \endtable
|
---|
| 173 |

|
---|
| 175 | QMenuBar and QPopupMenu use.
