setting row height in QTreeView?

[gfunk]

Using SizeHintRole roles works perfectly!

I gave the delegate thing a try, but it didn't seem to work, wasn't even getting any breakpoints hit inside. Aren't delegates only used by the app when you try to edit a cell (such as by trying to double-click on it)

No, they also render items to the view and return size hints for them.
