[Qt-interest] QTreeWidget row colors

[Bruno Tezine]

Hi all, 
Does anybody know an easy way to set the background color for a
particular QTreeWidget row, not only the QTreeWidgetItem, but also the
branch part?
For example, if I use QTreeWidgetItem setBackGround it does not change
the left part of the row where branches are. 
Does anybody know how to solve that?
Thanks in advance, 
      Bruno.
