QShortcut:: QShortcut(const QKeySequence & key, QObject * parent, const char * member = nullptr, const char * ambiguousMember = nullptr, Qt::ShortcutContext context = Qt::WindowShortcut) Since no shortcut key sequence is specified, the shortcut will not emit any signals. Member Function Documentation QShortcut:: QShortcut( QObject * parent)Ĭonstructs a QShortcut object for the parent, which should be a QWindow or a QWidget. The simplest way to create a shortcut for a particular widget is to construct the shortcut with a key sequence.
Alternatively, shortcuts may be associated with other types of actions in the QAction class. However, because mnemonic shortcuts do not fit in with Aqua's guidelines, Qt will not show the shortcut character underlined.įor applications that use menus, it may be more convenient to use the convenience functions provided in the QMenu class to assign keyboard shortcuts to menu items as they are created. Call qt_set_sequence_auto_mnemonic() to enable them.
On Mac, shortcuts are disabled by default. On Windows, shortcuts are normally not displayed until the user presses the Alt key, but this is a setting the user can change. On X11 the ampersand will not be shown and the character will be underlined. The widget might consume and perform an action on a given shortcut. "E&xit" will create the shortcut Alt+X (use '&' to display an actual ampersand). This will automatically create a mnemonic (a shortcut) for that character, e.g.
In widget applications, certain widgets can use '&' in front of a character. The shortcut can be set up to contain all the key presses necessary to describe a keyboard shortcut, including the states of modifier keys such as Shift, Ctrl, and Alt. The QShortcut class provides a way of connecting keyboard shortcuts to Qt's signals and slots mechanism, so that objects can be informed when a shortcut is executed.
