Give background colour to QHeaderView?

[Vadi2]

I create a QTreeWidgetItem and add it as the root-level item to TTreeWidget, which is a subclass of QTreeWidget. To give it a background in a way that hinders the users ability to use setStyleSheet() I can just use QTreeWidgetItem->setBackground().

How can I give the widget a background that still allows the use of setStyleSheet()? I've tried targetting the table header via qss in so many ways and nothing is sticking.

Hi,

What about clearing the background when the user sets a non empty stylesheet ?

How can a stylesheet target the background?

If the stylesheet doesn't target the headers background, then the colour will simply lost and that's a bug. I need to re-add the colour back in via stylesheet.

See the QHeaderView example in Qt's documentation.
