Method Detail

onStart

protected boolean onStart(TouchData startedTouch)

Description copied from class: AbstractGestureRecognizer

Indicates that a touch has started, giving the gesture the chance to exclusively handle this touch as it moves.

Specified by:

onStart in class AbstractGestureRecognizer

Parameters:

startedTouch - the touch that has begun

Returns:

false to not capture the touch passed in, true to capture it so that later gestures do not hear about it. Returning true is equivelent to calling setCaptured(startedTouch, true)

onMove

protected void onMove(List<TouchData> touches)

Description copied from class: AbstractGestureRecognizer

Indicates that on or more touches are moving

Specified by:

onMove in class AbstractGestureRecognizer

onTap

protected void onTap(TouchData touchData)

onEnd

protected void onEnd(List<TouchData> touches)

Description copied from class: AbstractGestureRecognizer

Indicates that one or more touches have ended.

Specified by:

onEnd in class AbstractGestureRecognizer

Parameters:

touches - data for the now-ended touches (as opposed to #getTouches which no longer has those entries)

onCancel

protected void onCancel(List<TouchData> touches)

Description copied from class: AbstractGestureRecognizer

Indicates that one or more touches have been canceled by the browser or by the gesture itself being canceled (see #cancel).

Specified by:

onCancel in class AbstractGestureRecognizer

Parameters:

touches - data for the now-canceled touches (as opposed to #getTouches which no longer has those entries)

handlePreventDefault

Description copied from class: AbstractGestureRecognizer

Intended to allow subclasses to determine if preventDefault should be called
