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.

See also: ignore()

Definition at line 313 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.

◆ accept() [3/3]

void QGestureEvent::accept ( Qt::GestureType gestureType )

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

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

Here is the caller graph for this function:

◆ ignore() [1/3]

void QEvent::ignore

inline

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()

Definition at line 314 of file qcoreevent.h.

◆ ignore() [2/3]

void QGestureEvent::ignore ( QGesture * gesture )

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

Clearing the accept flag indicates that the event receiver does not want the gesture. Unwanted gestures may be propagated to the parent widget.

Here is the caller graph for this function:

◆ ignore() [3/3]

void QGestureEvent::ignore ( Qt::GestureType gestureType )

Clears the accept flag parameter of the given gestureType, the equivalent of calling \l{QGestureEvent::setAccepted()}{setAccepted(gesture, false)}.

Clearing the accept flag indicates that the event receiver does not want the gesture. Unwanted gestures may be propagated to the parent widget.

◆ setAccepted() [1/3]

virtual void QEvent::setAccepted

inline

Definition at line 310 of file qcoreevent.h.

Here is the caller graph for this function:

◆ setAccepted() [2/3]

void QGestureEvent::setAccepted	(	QGesture *	gesture,
		bool	value
	)

Sets the accept flag of the given gesture object to the specified value.

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

By default, gestures in events of type QEvent::Gesture are accepted, and gestures in QEvent::GestureOverride events are ignored.

For convenience, the accept flag can also be set with \l{QGestureEvent::accept()}{accept(gesture)}, and cleared with \l{QGestureEvent::ignore()}{ignore(gesture)}.

Here is the caller graph for this function:

◆ setAccepted() [3/3]

void QGestureEvent::setAccepted	(	Qt::GestureType	gestureType,
		bool	value
	)

Sets the accept flag of the given gestureType object to the specified value.

Setting the accept flag indicates that the event receiver wants to receive gestures of the specified type, gestureType. Unwanted gestures may be propagated to the parent widget.

By default, gestures in events of type QEvent::Gesture are accepted, and gestures in QEvent::GestureOverride events are ignored.

For convenience, the accept flag can also be set with \l{QGestureEvent::accept()}{accept(gestureType)}, and cleared with \l{QGestureEvent::ignore()}{ignore(gestureType)}.
