From 01ce2e9eee41cc0c24b0d16465710a28ea337d5d Mon Sep 17 00:00:00 2001 From: Jeff Brown Date: Sun, 26 Sep 2010 22:20:12 -0700 Subject: Add suuport for splitting touch events across windows. This feature is currently used to enable dragging the start and end selection handles of a TextView at the same time. Could be used for other things later. Deleted some dead code in ArrowKeyMovementMethod and CursorControllers.
