From 119a8ddcd7c8de0607309b37f9ef83439b607f17 Mon Sep 17 00:00:00 2001 From: Andrew den Exter Date: Mon, 28 Feb 2011 16:54:08 +1000 Subject: Don't return positions within preedit text from positionAt(). Preedit text isn't visible outside the inner workings of the Text elements so any position returned that is greater than the current cursor position is invalid.
