Method Details

onTap

public void onTap(Event.XY where)

Description copied from class: Tapper

Called when a tap occurs. By default, this just calls Tapper.onTap(). Subclasses overriding needn't call super.

Overrides:

onTap in class Tapper

Parameters:

where - the pointer's end position

onDoubleTap

public void onDoubleTap()

Called when a double tap occurs. This is a simpler version of onDoubleTap(Event.XY), for subclasses that don't require the event position.

onDoubleTap

public void onDoubleTap(Event.XY where)

Called when a double tap occurs. By default, this just calls onDoubleTap(). Subclasses overriding this needn't call super.

Parameters:

where - the pointer's end position (for the 2nd tap)
