extends Object

Class Overview

Gesture detector based on touch events.

This class allows us to get click events when we need them, but not to consume them when we are temporarily not interested in them. Doing View.setClickable(true) will cause for the view always to consume click event, even if View.performClick is overridden to return false. That means even though our view didn't handle the click event, the event will not get propagated upwards. Result of View.onTouchEvent is handled correctly though so we use that instead.

This class currently only detects clicks.
