- \class QGestureRecognizer
- \since 4.6
-
- \brief The QGestureRecognizer class is the base class for
- implementing custom gestures.
-
- This is a base class, to create a custom gesture type, you should
- subclass it and implement its pure virtual functions.
-
- Usually gesture recognizer implements state machine, storing its
- state internally in the recognizer object. The recognizer receives
- input events through the \l{QGestureRecognizer::}{filterEvent()}
- virtual function and decides whether the parsed event should
- change the state of the recognizer - i.e. if the event starts or
- ends a gesture or if it isn't related to gesture at all.
-*/
-
-/*!
- \enum QGestureRecognizer::Result
- \since 4.6
-
- This enum type defines the state of the gesture recognizer.
-
- \value Ignore Gesture recognizer ignores the event.
-
- \value NotGesture Not a gesture.
-
- \value GestureStarted The continuous gesture has started. When the
- recognizer is in this state, a \l{QGestureEvent}{gesture event}
- containing QGesture objects returned by the
- \l{QGestureRecognizer::}{getGesture()} will be sent to a widget.
-
- \value GestureFinished The gesture has ended. A
- \l{QGestureEvent}{gesture event} will be sent to a widget.
-
- \value MaybeGesture Gesture recognizer hasn't decided yet if a
- gesture has started, but it might start soon after the following
- events are received by the recognizer. This means that gesture
- manager shouldn't reset() the internal state of the gesture
- recognizer.
-*/
-
-/*! \fn QGestureRecognizer::Result QGestureRecognizer::filterEvent(const QEvent *event)
-
- This is a pure virtual function that needs to be implemented in
- subclasses.
-
- Parses input \a event and returns the result, which specifies if
- the event sequence is a gesture or not.
-*/
-
-/*! \fn QGesture* QGestureRecognizer::getGesture()
-
- Returns a gesture object that will be send to the widget. This
- function is called when the gesture recognizer changed its state
- to QGestureRecognizer::GestureStarted or
- QGestureRecognizer::GestureFinished.
-
- The returned QGesture object must point to the same object in a
- single gesture sequence.
-
- The gesture object is owned by the recognizer itself.
-*/
-
-/*! \fn void QGestureRecognizer::reset()
-
- Resets the internal state of the gesture recognizer.
-*/

-/*! \fn void QGestureRecognizer::stateChanged(QGestureRecognizer::Result result)

- The gesture recognizer might emit the stateChanged() signal when
- the gesture state changes asynchronously, i.e. without any event
- being filtered through filterEvent().
