[Interest] QTreeWidget displays blank widget

From the discussion I had with support, it appears that QTableWidget is expecting a 
QTableWidgetItem to define the colors for QPalette::ForegroundRole and QPalette::BackgroundRole,
but since you're using setCellWidget() you're most likely not adding a QTableWidgetItem to the
cell. Which even if you were, I don't think would get what you want since you have two different
background colors (the orange and the blue) as the background of the two labels. I don't know
if using QStyledItemDelegate gets you over that hurdle either, since I don't see how it allows you
to set different BackgroundRole values for the QLabel child widgets?

If you come up with a good solution, please respond to the list (or at least respond to me personally!)
as I'm interested in the correct solution to this as well just in case we decide to come back around to
this idea for our project.
