Display PopupScreen on TouchEvent.DOWN - who gets TouchEvent.UP?

I'm writing this message both in hope to get an answer and, in case I find out myself, to post the reply with my findings.

 

Here is the situation:

 

I display (pushScreen inside invokeLater) a small PopupScreen (a tooltip) when a user touches a Field with the tooltip text (title, in HTML terminology) defined.

 

When the user removes the finger, I want the tooltip to go away (popScreen or close() from the popup itself).  However, I cannot find out which screen - the MainScreen below or the PopupScreen above - gets the TouchEvent.UP in this situation.  Debugger does not help much as it disrupts the touch event sequence.

 

If anyone has done something similar, please respond.

Found out the answer - no one gets TouchEvent.UP!  Due to a Screen being pushed the MainScreen gets TouchEvent.CANCEL immediately, as soon as the tooltip becomes visible.  Use the information as you see fit.
