'Qt abstract buttom . How to draw the background in different z levels to avoid background overlaping with other buttons
I have design a Qt object derived from QAbstractButton. It has some transparent drawings that I use in the background and an opaque solid shape for the foreground.
The background is big, as a shadow, and two objects could be close and partially overlapped.
Foregrounds never overlap between then (by design) but background could overlap the other object (in both areas).
What I want to do is to draw foreground and background in different levels. I mean, first tp draw the backgrounds and then the foregrounds, in that way I will never overlap the foreground area.
Is it possible?
I'm using Qt 5.12.
Update: Adding some sketches
B2 yellow background is drawed over B1 solid foregraund, and it is not desired.
