Detailed Description¶

Warning

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() .

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property autoRepeatᅟ: 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.

Access functions:

autoRepeat()
setAutoRepeat()

property contextᅟ: Qt.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 Qt::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 Qt::WindowShortcut.

Access functions:

context()
setContext()

property enabledᅟ: 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

Access functions:

isEnabled()
setEnabled()

property keyᅟ: QKeySequence¶

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

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.

Access functions:

key()
setKey()

__init__(parent)¶

Parameters:: parent – QObject

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.

See also

setKey()

__init__(arg__1, arg__2, arg__3[, arg__4=Qt.WindowShortcut])

Parameters:

arg__1 – QKeySequence
arg__2 – QObject
arg__3 – PyCallable
arg__4 – ShortcutContext

__init__(arg__1, arg__2, arg__3[, arg__4=Qt.WindowShortcut])

Parameters:

arg__1 – StandardKey
arg__2 – QObject
arg__3 – PyCallable
arg__4 – ShortcutContext

__init__(key, parent[, member=None[, ambiguousMember=None[, context=Qt.WindowShortcut]]])

Parameters:

key – StandardKey
parent – QObject
member – str
ambiguousMember – str
context – ShortcutContext

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.

__init__(key, parent[, member=None[, ambiguousMember=None[, context=Qt.WindowShortcut]]])

Parameters:

key – QKeySequence
parent – QObject
member – str
ambiguousMember – str
context – ShortcutContext

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.

activated()¶

This signal is emitted when the user types the shortcut’s key sequence.

See also

activatedAmbiguously()

activatedAmbiguously()¶

When a key sequence is being typed at the keyboard, it is said to be ambiguous as long as it matches the start of more than one shortcut.

When a shortcut’s key sequence is completed, activatedAmbiguously() is emitted if the key sequence is still ambiguous (i.e., it is the start of one or more other shortcuts). The activated() signal is not emitted in this case.

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.

whatsThis()¶

Return type:: str
