Detailed Description

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

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 Gestures Programming document.

Gesture Properties

The class has a list of properties that can be queried by the user to get some gesture-specific arguments. For example, the pinch gesture has a scale factor that is exposed as a property.

Developers of custom gesture recognizers can add additional properties in order to provide additional information about a gesture. This can be done by adding new dynamic properties to a QGesture object, or by subclassing the QGesture class (or one of its subclasses).

Lifecycle of a Gesture Object

A QGesture instance is implicitly created when needed and is owned by Qt. Developers should never destroy them or store them for later use as Qt may destroy particular instances of them and create new ones to replace them.

The registered gesture recognizer monitors the input events for the target object via its recognize() function, updating the properties of the gesture object as required.

The gesture object may be delivered to the target object in a QGestureEvent if the corresponding gesture is active or has just been canceled. Each event that is delivered contains a list of gesture objects, since support for more than one gesture may be enabled for the target object. Due to the way events are handled in Qt, gesture events may be filtered by other objects.

See also QGestureEvent and QGestureRecognizer.

Member Enumeration Documentation

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

Enumerator
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.

CancelNone 

On accepting this gesture no other gestures will be affected.

Constructor & Destructor Documentation

QtGui.QGesture.QGesture ( System.Type  dummy)
protected
QtGui.QGesture.QGesture ( QObject  parent = null)

Constructs a new gesture object with the given parent.

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

Here is the call graph for this function:

Member Function Documentation

override void QtGui.QGesture.CreateProxy ( )

Reimplemented from QtCore.QObject.

Reimplemented in QtGui.QTapGesture, QtGui.QTapAndHoldGesture, QtGui.QSwipeGesture, QtGui.QPinchGesture, and QtGui.QPanGesture.

Property Documentation

new IQGestureSignals QtGui.QGesture.Emit
getprotected
new QGesture.GestureCancelPolicy QtGui.QGesture.gestureCancelPolicy
getset

This property holds 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.

new Qt.GestureType QtGui.QGesture.GestureType
get

This property holds the type of the gesture.

new bool QtGui.QGesture.HasHotSpot
get

This property holds whether the gesture has a hot-spot.

new QPointF QtGui.QGesture.HotSpot
getset

This property holds 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.

new Qt.GestureState QtGui.QGesture.State
get

This property holds the current state of the gesture.

new QMetaObject QtGui.QGesture.StaticMetaObject
