I will try to recall what I did once.
Instantiate and add subclass  of QWidgetAction to the menu.
Such subclass had to instantiate your widget (better not to derive it from
To do this override createWidget. Such widget can be any complex or simple

If not mistaken I had explicitly call setAutoFillBackground(true ) in a
widget constructor.
You would also have to close menu yourself as a reaction on appropriate
events (for example item selection)
for example in your widget when user selected item you might call

 Q_ASSERT(   parentWidget()->inherits( "QMenu" ) );
  parentWidget() ->close()

Hope this helps,
