Detailed Description

The QGestureEvent class provides the description of triggered gestures.

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.

Constructor & Destructor Documentation

QGestureEvent::QGestureEvent ( const QList< QGesture * > & gestures )

explicit

Creates new QGestureEvent containing a list of gestures.

QGestureEvent::~QGestureEvent ( )

Destroys QGestureEvent.

Method Documentation

void QEvent::accept ( )

usinginline

Sets the accept flag of the event object, equivalent to 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()

void QGestureEvent::accept ( QGesture * gesture )

Sets the accept flag of the given gesture object, the equivalent of calling setAccepted(gesture, true). Setting the accept flag indicates that the event receiver wants the gesture. Unwanted gestures may be propagated to the parent widget.

See also: QGestureEvent::ignore()

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

Sets the accept flag of the given gestureType, the equivalent of calling setAccepted(gestureType, true). Setting the accept flag indicates that the event receiver wants the gesture. Unwanted gestures may be propagated to the parent widget.

See also: QGestureEvent::ignore()

QList< QGesture * > QGestureEvent::activeGestures ( ) const

Returns a list of active (not canceled) gestures.

QList< QGesture * > QGestureEvent::canceledGestures ( ) const

Returns a list of canceled gestures.

QGesture * QGestureEvent::gesture ( Qt::GestureType gestureType ) const

Returns a gesture object by gestureType.

QList< QGesture * > QGestureEvent::gestures ( ) const

Returns all gestures that are delivered in the event.

void QEvent::ignore ( )

usinginline

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()

void QGestureEvent::ignore ( QGesture * gesture )

Clears the accept flag parameter of the given gesture object, the equivalent of calling 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.

See also: QGestureEvent::accept()

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

Clears the accept flag parameter of the given gestureType, the equivalent of calling 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.

See also: QGestureEvent::accept()

bool QEvent::isAccepted ( ) const

usinginline

Returns the accept flag of the event object.

Setting the accept parameter indicates that the event receiver wants the event. Unwanted events might be propagated to the parent widget. By default, isAccepted() is set to true, but do not rely on this as subclasses may choose to clear it in their constructor. The accept flag can also be set with accept() and cleared with ignore().

bool QGestureEvent::isAccepted ( QGesture * gesture ) const

Returns true if the gesture is accepted, otherwise returns false.

bool QGestureEvent::isAccepted ( Qt::GestureType gestureType ) const

Returns true if the gesture of type gestureType is accepted, otherwise returns false.

QPointF QGestureEvent::mapToGraphicsScene ( const QPointF & gesturePoint ) const

Returns the scene-local coordinates if the gesturePoint is inside a graphics view.

This functiona might be useful when the gesture event is delivered to a QGraphicsObject to translate a point in screen coordinates to scene-local coordinates.

See also: QPointF::isNull()

void QEvent::setAccepted ( bool accepted )

usinginline

Sets the accept flag of the event object.

Setting the accept parameter indicates that the event receiver wants the event. Unwanted events might be propagated to the parent widget. By default, isAccepted() is set to true, but do not rely on this as subclasses may choose to clear it in their constructor. The accept flag can also be set with accept(), and cleared with ignore().

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

If isAccepted is true then the given gesture object is marked as accepted. If it is false then the gesture is marked as ignored. Accepting an event means the receiver has processed the gesture. Ignored 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 accept(gesture) and cleared with ignore(gesture).

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

If isAccepted is true then the given gestureType is marked as accepted. If it is false then the gestureType is marked as ignored. Accepting an event means the receiver has processed the gesture. Ignored 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 accept(gestureType) and cleared with ignore(gestureType).

void QGestureEvent::setWidget ( QWidget * widget )

Sets the value of the property to widget.

QWidget * QGestureEvent::widget ( ) const

Returns the widget on which the event occurred.
