QTabBar background and QTabWidgets corner widget

[steve]

Hi,
I'm trying to style the background of the QTabBar for my QTabWidget
@QTabBar{background-color:white;}@
This works fine however the background of the QTabWidgets cornerwidget is not affected.

This image shows a QTabBar I've styled to have a white background, and a QLabel set as the corner widget styled with a blue background.

The QTabBar is shrinking to fit the corner widget which makes sense, however I have no idea how to set the background that appears above the label. For example, trying to set a background to QTabWidget::right-corner does not work.

Any ideas?
