Problem with panel (child button not a have reactions on events)

[Dober_Net]

Hi, I’m making an addon and experienced one problem: Child panel does not respond on “panel.Hovered” and “panel.DoClick” also doesn’t have any reaction at “self.Hovered” and “self.DoClick” 
(child is a exit button on screenshots)

Here is code fragment

Problem solved! I changed parent from DImage (wallpaper) to main panel (desktop), if you have same problem try to avoid setting DImage as parent
