Detailed Description

The QGesture class represents a gesture, containing properties that describe the corresponding user input.

Since: 4.6

\inmodule QtWidgets

Gesture objects are not constructed directly by developers. They are created by the QGestureRecognizer object that is registered with the application; see QGestureRecognizer::registerRecognizer().

For an overview of gesture handling in Qt and information on using gestures in your applications, see the \l{Gestures in Widgets and Graphics View} document.

Member Enumeration Documentation

◆ GestureCancelPolicy

enum QGesture::GestureCancelPolicy

This enum describes how accepting a gesture can cancel other gestures automatically.

\value CancelNone On accepting this gesture no other gestures will be affected.

\value CancelAllInContext On accepting this gesture all gestures that are active in the context (respecting the Qt::GestureFlag that were specified when subscribed to the gesture) will be cancelled.

Enumerator
CancelNone
CancelAllInContext

Constructor & Destructor Documentation

◆ QGesture() [1/2]

QGesture::QGesture ( QObject * parent = nullptr )

explicit

Constructs a new gesture object with the given parent.

QGesture objects are created by gesture recognizers in the QGestureRecognizer::create() function.

Definition at line 104 of file qgesture.cpp.

◆ ~QGesture()

QGesture::~QGesture ( )

Destroys the gesture object.

Definition at line 121 of file qgesture.cpp.

◆ QGesture() [2/2]

QGesture::QGesture	(	QGesturePrivate &	dd,
		QObject *	parent
	)

protected

Property Documentation

◆ gestureCancelPolicy

QGesture::gestureCancelPolicy

readwrite

the policy for deciding what happens on accepting a gesture

On accepting one gesture Qt can automatically cancel other gestures that belong to other targets. The policy is normally set to not cancel any other gestures and can be set to cancel all active gestures in the context. For example for all child widgets.

Definition at line 324 of file qgesture.h.

◆ gestureType

QGesture::gestureType

read

the type of the gesture

Definition at line 324 of file qgesture.h.

◆ hasHotSpot

QGesture::hasHotSpot

read

whether the gesture has a hot-spot

Definition at line 324 of file qgesture.h.

◆ hotSpot

QGesture::hotSpot

readwrite

The point that is used to find the receiver for the gesture event.

The hot-spot is a point in the global coordinate system, use QWidget::mapFromGlobal() or QGestureEvent::mapToGraphicsScene() to get a local hot-spot.

The hot-spot should be set by the gesture recognizer to allow gesture event delivery to a QGraphicsObject.

Definition at line 324 of file qgesture.h.

◆ state

QGesture::state

read

the current state of the gesture

Definition at line 324 of file qgesture.h.
