From d8465414e6fd543cfc20e732030dedd8d2bc685f Mon Sep 17 00:00:00 2001 From: Janne Anttila Date: Thu, 25 Feb 2010 11:28:47 +0200 Subject: Improvements to itemview keypad navigation in S60. The logic used in this commit is partially taken from sliders. This commit makes it possible to interact (change row or column) in itemview even itemview does not have editFocus. Interacting without editFocus is enabled when it is not possible to keypad navigate to reuqested direction. In addition if keypad navigation to any direction is not possible (i.e there is only one listwidget on screen), there is no sense to add "done" softkey to get out of edit focus.
