[Qt-interest] Icon sidepane in Windows Vista/7 (Fixed size for a QListWidgetItem?)

[Lukas Hetzenecker]

Hello,

i have a QListWidget that displays a button bar, like in KDEs Kontact.
I attached my current implementation, written in C++, and my original 
implementation in Python/PyQt4. This works fine with Linux/Oxygen theme 
(as you can see in this screenshot: http://imagebin.ca/img/Od0zEZ.jpg ) and 
Windows XP, but looks ugly in Windows Vista and Windows 7 (as you can see 
here: http://imagebin.ca/img/umwpMN1.jpg ).

Is it possible to extend the region of the background of a selected item in 
Windows Vista?

I even tried it with a QStyledItemDelegate and QStyleOptionViewItemV4 
(decorationSize attribute), but this didn't help.

Does anybody know what I should try else?

Thanks for your help,
Lukas
