Thank you for you're reply Spitfire

The virtual right mouse button needs to filter the left mouse click and check if it is held for 750ms, i don't have to filter the context menu event, this is the even that I send when the mouse is clicked for 750ms.

I've solved it by just filtering out the first mouse down event (leftbutton), the events are fired in order of visibility and the QLable is on top/first.
