How can I retrieve the default 'selection-background-color' from a combobox

[Bill52]

Default means: before any stylesheet was set on the widget.
Would someone be kind to give the syntax please? I can't see how this could be done.

Many thanks.

You can use QWidget::palette() to retrieve the palette and then use
