[Qt-interest] Custom TreeWidget Items - css

[Willy P]

I'd like to design a tree widget with custom appearances at each
level.  Much like how Qt Designer categorizes / separates items w/
custom cells.  I've started learning about css and QStyleSheets and
I'm getting pretty comfortable making global changes.

But I don't know the CSS syntax to customize a particular level of a tree.

I imagine I'd have to make new classes like "RootLevelItem" and
"MidLevelItem" and "LeafItem" who inherit from QTreeWidgetItem.  Will
I be able to reference them through the css sheet?

Thanks in advance.
