Hello,
I want to change a button background color.
I have defined the color with 4 parameters RGB & Alpha, but there is no transparency but a gray with alpha= 0.
When i try in a new screen in the same app with just a button and a label , it,s work.
I found a solution, (for my app at least...)
I initialize the buttons when the window opens rather than in the designer.
I set the shape of the buttons to rounded, this removes the shadow with the value 16777215 for the background color.
If I set the color with RGB & Alpha, I have transparency but the rectangular shadow is present despite the rounded parameter.
