Member Function Documentation

create()

QGesture * QMacSwipeGestureRecognizer::create ( QObject * target )

overridevirtual

This function is called by Qt to create a new QGesture object for the given target (QWidget or QGraphicsObject).

Reimplement this function to create a custom QGesture-derived gesture object if necessary.

The application takes ownership of the created gesture object.

Reimplemented from QGestureRecognizer.

Definition at line 20 of file qmacgesturerecognizer.cpp.

recognize()

QGestureRecognizer::Result QMacSwipeGestureRecognizer::recognize ( QGesture * gesture, QObject * watched, QEvent * event )

overridevirtual

Handles the given event for the watched object, updating the state of the gesture object as required, and returns a suitable result for the current recognition step.

This function is called by the framework to allow the recognizer to filter input events dispatched to QWidget or QGraphicsObject instances that it is monitoring.

The result reflects how much of the gesture has been recognized. The state of the gesture object is set depending on the result.

reset()

void QMacSwipeGestureRecognizer::reset ( QGesture * gesture )

overridevirtual

This function is called by the framework to reset a given gesture.

Reimplement this function to implement additional requirements for custom QGesture objects. This may be necessary if you implement a custom QGesture whose properties need special handling when the gesture is reset.

Reimplemented from QGestureRecognizer.
