Member Function Documentation

◆ create()

QGesture * QFlickGestureRecognizer::create ( QObject * target )

overridevirtual

\reimp

Reimplemented from QGestureRecognizer.

Definition at line 303 of file qflickgesture.cpp.

References Qt::NoButton.

◆ recognize()

QGestureRecognizer::Result QFlickGestureRecognizer::recognize	(	QGesture *	state,
		QObject *	watched,
		QEvent *	event )

overridevirtual

The recognize function detects a touch event suitable to start the attached QScroller. The QFlickGesture will be triggered as soon as the scroller is no longer in the state QScroller::Inactive or QScroller::Pressed. It will be finished or canceled at the next QEvent::TouchEnd. Note that the QScroller might continue scrolling (kinetically) at this point.

Implements QGestureRecognizer.
