[Qt-interest] Broken rendering of QTreeWidget items on Symbian with Qt 4.7.0 RC1

[Constantin Makshin]

Hi!

Recently I installed Qt 4.7.0 RC1 on my Symbian phone and, as usually, decided to perform a "quick and dirty" test using my application developed specifically for that purpose (check basic Qt functionality).

There I saw than rendering of QTreeWidget items is broken — they look more like [push] buttons instead than "classic" list/tree items. It works correctly on Windows and Linux and worked correctly with Symbian versions of Qt 4.6.x.

Can anyone confirm the problem (I wouldn't want to bother Qt developers with reports about bugs in my code)? The screenshot and source code are attached to this message.
