monitor mouse events but not capture them

[Martin Sladecek]

Oh, I see. So it's not a PopupWindow at all.
Events can pass only though parent-child hierarchy, so you can't catch 
an Event in your "circular menu" pane and then pass it to some other 
children of the parent StackPane. The menu pane would have to be parent 
of the controls in the StackPane.
So again, you'd need RT-20184 to determine the target again by 
temporarily making the menu pane mouse transparent, doing Scene.pick and 
then redirecting the Event by Event.fireEvent().

But I think reworking you menu to be a PopupWindow should work. The 
transparent areas in the circular menu should pass mouse events to the 
underlying window.
