Detailed Description

The QGestureEvent class provides the description of triggered gestures.

Since
4.6

\inmodule QtWidgets

The QGestureEvent class contains a list of gestures, which can be obtained using the gestures() function.

The gestures are either active or canceled. A list of those that are currently being executed can be obtained using the activeGestures() function. A list of those which were previously active and have been canceled can be accessed using the canceledGestures() function. A gesture might be canceled if the current window loses focus, for example, or because of a timeout, or for other reasons.

If the event handler does not accept the event by calling the generic QEvent::accept() function, all individual QGesture object that were not accepted and in the Qt::GestureStarted state will be propagated up the parent widget chain until a widget accepts them individually, by calling QGestureEvent::accept() for each of them, or an event filter consumes the event.

Member Function Documentation

◆ accept() [1/3]

void QEvent::accept ( )
inline

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.

ignore()

Definition at line 310 of file qcoreevent.h.

◆ accept() [2/3]

void QGestureEvent::accept ( QGesture * gesture)

Sets the accept flag of the given gesture object, the equivalent of calling \l{QGestureEvent::setAccepted()}{setAccepted(gesture, true)}.

Setting the accept flag indicates that the event receiver wants the gesture. Unwanted gestures may be propagated to the parent widget.
