186 \class QAction-
187 \brief The QAction class provides an abstract user interface-
188 action that can be inserted into widgets.-
189-
190 \ingroup mainwindow-classes-
191 \inmodule QtWidgets-
192-
193 \omit-
194 * parent and widget are different-
195 * parent does not define context-
196 \endomit-
197-
198 In applications many common commands can be invoked via menus,-
199 toolbar buttons, and keyboard shortcuts. Since the user expects-
200 each command to be performed in the same way, regardless of the-
201 user interface used, it is useful to represent each command as-
202 an \e action.-
203-
204 Actions can be added to menus and toolbars, and will-
205 automatically keep them in sync. For example, in a word processor,-
206 if the user presses a Bold toolbar button, the Bold menu item-
207 will automatically be checked.-
208-
209 Actions can be created as independent objects, but they may-
210 also be created during the construction of menus; the QMenu class-
211 contains convenience functions for creating actions suitable for-
212 use as menu items.-
213-
214 A QAction may contain an icon, menu text, a shortcut, status text,-
215 "What's This?" text, and a tooltip. Most of these can be set in-
216 the constructor. They can also be set independently with-
217 setIcon(), setText(), setIconText(), setShortcut(),-
218 setStatusTip(), setWhatsThis(), and setToolTip(). For menu items,-
219 it is possible to set an individual font with setFont().-
220-
221 Actions are added to widgets using QWidget::addAction() or-
222 QGraphicsWidget::addAction(). Note that an action must be added to a-
223 widget before it can be used; this is also true when the shortcut should-
224 be global (i.e., Qt::ApplicationShortcut as Qt::ShortcutContext).-
225-
226 Once a QAction has been created it should be added to the relevant-
227 menu and toolbar, then connected to the slot which will perform-
228 the action. For example:-
229-
230 \snippet mainwindows/application/mainwindow.cpp 19-
231 \codeline-
232 \code-
233 fileMenu->addAction(openAct);-
234 \endcode-
235-
236 We recommend that actions are created as children of the window-
237 they are used in. In most cases actions will be children of-
238 the application's main window.-

258 This enum describes how an action should be moved into the application menu on \macos.-
259-
260 \value NoRole This action should not be put into the application menu-
261 \value TextHeuristicRole This action should be put in the application menu based on the action's text-
262 as described in the QMenuBar documentation.-
263 \value ApplicationSpecificRole This action should be put in the application menu with an application specific role-
264 \value AboutQtRole This action handles the "About Qt" menu item.-
265 \value AboutRole This action should be placed where the "About" menu item is in the application menu. The text of-
266 the menu item will be set to "About <application name>". The application name is fetched from the-
267 \c{Info.plist} file in the application's bundle (See \l{Qt for macOS - Deployment}).-
268 \value PreferencesRole This action should be placed where the "Preferences..." menu item is in the application menu.-
269 \value QuitRole This action should be placed where the Quit menu item is in the application menu.-
270-
271 Setting this value only has effect on items that are in the immediate menus-
272 of the menubar, not the submenus of those menus. For example, if you have-
273 File menu in your menubar and the File menu has a submenu, setting the-
274 MenuRole for the actions in that submenu have no effect. They will never be moved.-
