From a30d4162ddb30b62b8d003b099d3ca8ae0b0ed0b Mon Sep 17 00:00:00 2001 From: Lars Knoll Date: Mon, 5 Sep 2011 12:53:33 +0200 Subject: [PATCH] Refactor the input framework Results of the ongoing workshop in Oslo: QInputPanel will be the application facing interface for controlling the input context as well as querying things like the position of the virtual keyboard. QInputContext is significantly cleaned up and only there as a compatibility API for existing code.
