Detailed Description#

Qt’s main event loop ( exec() ) fetches native window system events from the event queue, translates them into QEvents, and sends the translated events to QObject s.

In general, events come from the underlying window system ( spontaneous() returns true), but it is also possible to manually send events using sendEvent() and postEvent() ( spontaneous() returns false).

QObjects receive events by having their event() function called. The function can be reimplemented in subclasses to customize event handling and add additional event types; QWidget::event() is a notable example. By default, events are dispatched to event handlers like timerEvent() and QWidget::mouseMoveEvent(). installEventFilter() allows an object to intercept events destined for another object.

The basic QEvent contains only an event type parameter and an “accept” flag. The accept flag set with accept() , and cleared with ignore() . It is set by default, but don’t rely on this as subclasses may choose to clear it in their constructor.

Subclasses of QEvent contain additional parameters that describe the particular event.

PySide6.QtCore.QEvent.__repr__()#

Return type:: object

PySide6.QtCore.QEvent.accept()#

Sets the accept flag of the event object, the equivalent of calling setAccepted (true).

Setting the accept parameter indicates that the event receiver wants the event. Unwanted events might be propagated to the parent widget.

See also

ignore()

PySide6.QtCore.QEvent.clone()#

Return type:: PySide6.QtCore.QEvent

Creates and returns an identical copy of this event.

PySide6.QtCore.QEvent.ignore()#

Clears the accept flag parameter of the event object, the equivalent of calling setAccepted (false).

Clearing the accept parameter indicates that the event receiver does not want the event. Unwanted events might be propagated to the parent widget.

See also

accept()

PySide6.QtCore.QEvent.isAccepted()#

Return type:: bool

PySide6.QtCore.QEvent.isInputEvent()#

Return type:: bool

Returns true if the event object is a QInputEvent or one of its subclasses.

PySide6.QtCore.QEvent.isPointerEvent()#

Return type:: bool

Returns true if the event object is a QPointerEvent or one of its subclasses.

PySide6.QtCore.QEvent.isSinglePointEvent()#

Return type:: bool

Returns true if the event object is a subclass of QSinglePointEvent.

static PySide6.QtCore.QEvent.registerEventType([hint=-1])#

Parameters:: hint – int
Return type:: int

Registers and returns a custom event type. The hint provided will be used if it is available, otherwise it will return a value between User and MaxUser that has not yet been registered. The hint is ignored if its value is not between User and MaxUser .

Returns -1 if all available values are already taken or the program is shutting down.

PySide6.QtCore.QEvent.setAccepted(accepted)#

Parameters:: accepted – bool
