Detailed Description

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. 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.

In widget applications, certain widgets can use ‘&’ in front of a character. This will automatically create a mnemonic (a shortcut) for that character, e.g. “E&xit” will create the shortcut Alt+X (use ‘&&’ to display an actual ampersand). The widget might consume and perform an action on a given shortcut. On X11 the ampersand will not be shown and the character will be underlined. On Windows, shortcuts are normally not displayed until the user presses the Alt key, but this is a setting the user can change. On Mac, shortcuts are disabled by default. Call qt_set_sequence_auto_mnemonic() to enable them. However, because mnemonic shortcuts do not fit in with Aqua’s guidelines, Qt will not show the shortcut character underlined.

For 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. Alternatively, shortcuts may be associated with other types of actions in the QAction class.

The simplest way to create a shortcut for a particular widget is to construct the shortcut with a key sequence. For example:

shortcut = QShortcut(QKeySequence(tr("Ctrl+O", "File|Open")),
                         parent)

When the user types the key sequence for a given shortcut, the shortcut’s activated() signal is emitted. (In the case of ambiguity, the activatedAmbiguously() signal is emitted.) A shortcut is “listened for” by Qt’s event loop when the shortcut’s parent widget is receiving events.

A shortcut’s key sequence can be set with setKey() and retrieved with key() . A shortcut can be enabled or disabled with setEnabled() , and can have “What’s This?” help text set with setWhatsThis() .

class PySide6.QtGui.QShortcut(arg__1, arg__2, arg__3[, arg__4=Qt.WindowShortcut])

PySide6.QtGui.QShortcut(arg__1, arg__2, arg__3[, arg__4=Qt.WindowShortcut])

PySide6.QtGui.QShortcut(key, parent[, member=None[, ambiguousMember=None[, context=Qt.WindowShortcut]]])

PySide6.QtGui.QShortcut(parent)

PySide6.QtGui.QShortcut(key, parent[, member=None[, ambiguousMember=None[, context=Qt.WindowShortcut]]])

Parameters

Constructs a QShortcut object for the parent, which should be a QWindow or a QWidget .

The shortcut operates on its parent, listening for QShortcutEvent s that match the standardKey. Depending on the ambiguity of the event, the shortcut will call the member function, or the ambiguousMember function, if the key press was in the shortcut’s context.

Constructs a QShortcut object for the parent, which should be a QWindow or a QWidget .

Since no shortcut key sequence is specified, the shortcut will not emit any signals.

setKey()

Constructs a QShortcut object for the parent, which should be a QWindow or a QWidget .

The shortcut operates on its parent, listening for QShortcutEvent s that match the key sequence. Depending on the ambiguity of the event, the shortcut will call the member function, or the ambiguousMember function, if the key press was in the shortcut’s context.

PySide6.QtGui.QShortcut.activated()
PySide6.QtGui.QShortcut.activatedAmbiguously()
PySide6.QtGui.QShortcut.autoRepeat()
Return type

bool

This property holds whether the shortcut can auto repeat.

If true, the shortcut will auto repeat when the keyboard shortcut combination is held down, provided that keyboard auto repeat is enabled on the system. The default value is true.

PySide6.QtGui.QShortcut.context()
Return type

ShortcutContext

This property holds the context in which the shortcut is valid.

A shortcut’s context decides in which circumstances a shortcut is allowed to be triggered. The normal context is WindowShortcut , which allows the shortcut to trigger if the parent (the widget containing the shortcut) is a subwidget of the active top-level window.

By default, this property is set to WindowShortcut .

PySide6.QtGui.QShortcut.id()
Return type

int

Note

This function is deprecated.

Returns the primary key binding’s ID.

See also

shortcutId()

PySide6.QtGui.QShortcut.isEnabled()
Return type

bool

This property holds whether the shortcut is enabled.

An enabled shortcut emits the activated() or activatedAmbiguously() signal when a QShortcutEvent occurs that matches the shortcut’s key() sequence.

If the application is in WhatsThis mode the shortcut will not emit the signals, but will show the “What’s This?” text instead.

By default, this property is true.

whatsThis

PySide6.QtGui.QShortcut.key()
Return type

PySide6.QtGui.QKeySequence

This property holds the shortcut’s primary key sequence.

This is a key sequence with an optional combination of Shift, Ctrl, and Alt. The key sequence may be supplied in a number of ways:

setKey(0) # no signal emitted
setKey(QKeySequence()) # no signal emitted
setKey(0x3b1) # Greek letter alpha
setKey(Qt.Key_D) # 'd', e.g. to delete
setKey('q') # 'q', e.g. to quit
setKey(Qt.CTRL | Qt.Key_P) # Ctrl+P, e.g. to print document
setKey("Ctrl+P") # Ctrl+P, e.g. to print document

By default, this property contains an empty key sequence.

PySide6.QtGui.QShortcut.keys()
Return type

Returns the list of key sequences which trigger this shortcut.

key setKeys()

PySide6.QtGui.QShortcut.setAutoRepeat(on)
Parameters

on – bool

This property holds whether the shortcut can auto repeat.

If true, the shortcut will auto repeat when the keyboard shortcut combination is held down, provided that keyboard auto repeat is enabled on the system. The default value is true.

PySide6.QtGui.QShortcut.setContext(context)
Parameters

context – ShortcutContext

This property holds the context in which the shortcut is valid.

A shortcut’s context decides in which circumstances a shortcut is allowed to be triggered. The normal context is WindowShortcut , which allows the shortcut to trigger if the parent (the widget containing the shortcut) is a subwidget of the active top-level window.

By default, this property is set to WindowShortcut .

PySide6.QtGui.QShortcut.setEnabled(enable)
Parameters

enable – bool

This property holds whether the shortcut is enabled.

An enabled shortcut emits the activated() or activatedAmbiguously() signal when a QShortcutEvent occurs that matches the shortcut’s key() sequence.

If the application is in WhatsThis mode the shortcut will not emit the signals, but will show the “What’s This?” text instead.

By default, this property is true.

whatsThis

PySide6.QtGui.QShortcut.setKey(key)
Parameters

key – PySide6.QtGui.QKeySequence

This property holds the shortcut’s primary key sequence.

This is a key sequence with an optional combination of Shift, Ctrl, and Alt. The key sequence may be supplied in a number of ways:

setKey(0) # no signal emitted
setKey(QKeySequence()) # no signal emitted
setKey(0x3b1) # Greek letter alpha
setKey(Qt.Key_D) # 'd', e.g. to delete
setKey('q') # 'q', e.g. to quit
setKey(Qt.CTRL | Qt.Key_P) # Ctrl+P, e.g. to print document
setKey("Ctrl+P") # Ctrl+P, e.g. to print document

By default, this property contains an empty key sequence.

PySide6.QtGui.QShortcut.setKeys(key)
Parameters

key – StandardKey

Sets the triggers to those matching the standard key key.

See also

key keys()

PySide6.QtGui.QShortcut.setKeys(keys)
Parameters

keys –

PySide6.QtGui.QShortcut.setWhatsThis(text)
Parameters

text – str

Sets the shortcut’s “What’s This?” help text.

The text will be shown when a widget application is in “What’s This?” mode and the user types the shortcut key() sequence.

To set “What’s This?” help on a menu item (with or without a shortcut key), set the help on the item’s action.

By default, the help text is an empty string.

This function has no effect in applications that don’t use widgets.
