[Qt-interest] Style sheet selector for QTreeView::item based on item role

[Volker]

Hi everyone.

Is there a way to define a style-rule for a item based on a ItemDataRole? 

Im looking for s.t. like a style rule selector which selects items based on 
anything which can be application controlled.


What i'm trying to archive is to give particular items a different look in a 
QTreeView depending on item properties expressed by data()+ItemDataRole.
I know that that this can be done by using e.g. BackgroundRole or even by 
subclassing ItemDelegate. But i like to stick to style sheets.
