My base is a b4X page. I have 9 imageviews built in the designer. I've start the gesturedetector for onetapconfirmed (rotating the bitmap of the imageview), doubletap (flipping the bitmap of the imageview), longtap (not coded jet) and dragging the imageview and everything works fine. But when I'am dragging an imageview, I want to bring it to the front. I tried to put the imageviews on a panel, no success. Elevation for the panel, Invalidate the imageview after bringtofront also nosuccess. So 2 questions: Where is the right location to place the bringtofront method? What I'am doing wrong? Is there a invalidate method for B4Xpages too? Okay that were 3 questions
