I'm trying to change a qwidget opacity, when it has a parent. As I found out the setWindowOpacity is working only for a window without parent. I tried to reimplement paintEvent for the widget. But in this case I changed only widget's opacity(made its background a bit transparant), not its elements. The question is: what I need to reimplement in case I want to change widget's opacity with its elements?
Thank you for your answers beforehand.
