I describe the following problem for Mouse Events as well as for Touch 
Events. I want to do the following. Having a click/tab area which has the 
following function:

   - If I press the mouse down /touch start in this area a GWT PopupPanel 
   should be displayed.
   - While the mouse is still pressed / touch is not released, the 
   PopupPanel should be able to handle Events such as MouseOverEvent / 
   TouchStartEvent.

I could manage to get the PopupPanel to occur. But, since the mouse is 
still pressed / touch not released there will no events be triggered on the 
PopupPanel. It does not matter if I use FocusPanel or mgwt TouchPanel 
inside the PopupPanel. Events will not be triggered if I enter the 
PopupPanel with the Mouse pressed or Touch pressed.

What the PopupPanel does:

The PopupPanel should serve as a context menu where one can tab, the popup 
menu occurs, one swipes over the popup menu (without releasing the 
mouse/finger) and release the mouse or the finger on the menu item one will 
choose.

Is there a way do enable events inside the PopupPanel when the event starts 
outside? Can I trigger the mousedown or touch start event when the 
PopupPanel occurs such that I can use events when I started the click/touch 
outside of the PopupPanel?

The following image shows this case:
