From 2d61a39dedfb2718cdb6c26b370b7e4103db9c4a Mon Sep 17 00:00:00 2001 From: Shawn Rutledge Date: Tue, 28 Jul 2015 15:24:29 +0200 Subject: Introduce TapHandler MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Device-agnostic tap/click detection. Also detect whether the taps or clicks occur close enough together in both time and space to be considered part of a multi-tap gesture.
