Method Detail

addMultiFingerTapHandler

public HandlerRegistration addMultiFingerTapHandler(MultiFingerTapHandler handler)

Adds a multi-finger tap handler.

Specified by:

addMultiFingerTapHandler in interface HasMultiFingerTapHandlers

multiFingerTapCondition

protected boolean multiFingerTapCondition(MultiFingerTapEvent evt)

Returns whether the specified MultiFingerTapEvent should be delivered to the handlers. This allows filtering multi-finger tap gestures to only those you really want. For example, if you only want to recognize two-finger taps, you would override this method and return evt.getFingerCount() == 2. The default implementation delegates the decision to the tap condition passed in the constructor.

onTouchStart

protected void onTouchStart(TouchStartEvent evt)

Invoked when a touch starts.

Overrides:

onTouchStart in class TouchGestureRecognizer

onTouchMove

protected void onTouchMove(TouchMoveEvent evt)

Invoked when a finger touching the screen is moved.

Overrides:

onTouchMove in class TouchGestureRecognizer

onTouchEnd

protected void onTouchEnd(TouchEndEvent evt)

Invoked when a finger touching the screen is lifted.

Overrides:

onTouchEnd in class TouchGestureRecognizer

onTouchCancel

protected void onTouchCancel(TouchCancelEvent evt)

Invoked when a touch event is canceled.

Overrides:

onTouchCancel in class TouchGestureRecognizer
