1207 \class QMenu -
1208 \brief The QMenu class provides a menu widget for use in menu -
1209 bars, context menus, and other popup menus. -
1210 -
1211 \ingroup mainwindow-classes -
1212 \ingroup basicwidgets -
1213 \inmodule QtWidgets -
1214 -
1215 A menu widget is a selection menu. It can be either a pull-down -
1216 menu in a menu bar or a standalone context menu. Pull-down menus -
1217 are shown by the menu bar when the user clicks on the respective -
1218 item or presses the specified shortcut key. Use -
1219 QMenuBar::addMenu() to insert a menu into a menu bar. Context -
1220 menus are usually invoked by some special keyboard key or by -
1221 right-clicking. They can be executed either asynchronously with -
1222 popup() or synchronously with exec(). Menus can also be invoked in -
1223 response to button presses; these are just like context menus -
1224 except for how they are invoked. -

1235 -
1236 \section1 Actions -
1237 -
1238 A menu consists of a list of action items. Actions are added with -
1239 the addAction(), addActions() and insertAction() functions. An action -
1240 is represented vertically and rendered by QStyle. In addition, actions -
1241 can have a text label, an optional icon drawn on the very left side, -
1242 and shortcut key sequence such as "Ctrl+X". -
1243 -
1244 The existing actions held by a menu can be found with actions(). -
1245 -
1246 There are four kinds of action items: separators, actions that -
1247 show a submenu, widgets, and actions that perform an action. -
1248 Separators are inserted with addSeparator(), submenus with addMenu(), -
1249 and all other items are considered action items. -
1250 -
1251 When inserting action items you usually specify a receiver and a -
1252 slot. The receiver will be notifed whenever the item is -
1253 \l{QAction::triggered()}{triggered()}. In addition, QMenu provides -
1254 two signals, activated() and highlighted(), which signal the -
1255 QAction that was triggered from the menu. -
1256 -
1257 You clear a menu with clear() and remove individual action items -
1258 with removeAction(). -
1259 -
1260 A QMenu can also provide a tear-off menu. A tear-off menu is a -
1261 top-level window that contains a copy of the menu. This makes it -
1262 possible for the user to "tear off" frequently used menus and -
1263 position them in a convenient place on the screen. If you want -
1264 this functionality for a particular menu, insert a tear-off handle -
1265 with setTearOffEnabled(). When using tear-off menus, bear in mind -
1266 that the concept isn't typically used on Microsoft Windows so -
1267 some users may not be familiar with it. Consider using a QToolBar -
1268 instead. -
1269 -
1270 Widgets can be inserted into menus with the QWidgetAction class. -
1271 Instances of this class are used to hold widgets, and are inserted -
1272 into menus with the addAction() overload that takes a QAction. -
1273 -
1274 Conversely, actions can be added to widgets with the addAction(), -
1275 addActions() and insertAction() functions. -
1276 -
1277 \warning To make QMenu visible on the screen, exec() or popup() should be -
1278 used instead of show(). -
1279 -
1280 \section1 QMenu on Qt for Windows CE -
1281 -
1282 If a menu is integrated into the native menubar on Windows Mobile we -
1283 do not support the signals: aboutToHide (), aboutToShow () and hovered (). -
1284 It is not possible to display an icon in a native menu on Windows Mobile. -
1285 -
1286 \section1 QMenu on Mac OS X with Qt build against Cocoa -
1287 -
1288 QMenu can be inserted only once in a menu/menubar. Subsequent insertions will -
1289 have no effect or will result in a disabled menu item. -
1290 -
1291 See the \l{mainwindows/menus}{Menus} example for an example of how -
1292 to use QMenuBar and QMenu in your application. -
1293 -
1294 \b{Important inherited functions:} addAction(), removeAction(), clear(), -
1295 addSeparator(), and addMenu(). -

2073 Executes a menu synchronously. -
2074 -
2075 The menu's actions are specified by the list of \a actions. The menu will -
2076 pop up so that the specified action, \a at, appears at global position \a -
2077 pos. If \a at is not specified then the menu appears at position \a -
2078 pos. \a parent is the menu's parent widget; specifying the parent will -
2079 provide context when \a pos alone is not enough to decide where the menu -
2080 should go (e.g., with multiple desktops or when the parent is embedded in -
2081 QGraphicsView). -
2082 -
2083 The function returns the triggered QAction in either the popup -
2084 menu or one of its submenus, or 0 if no item was triggered -
2085 (normally because the user pressed Esc). -
