How to Implement Acrylic Effect in Qt UI?

[froxy]

I'm trying to apply an acrylic effect to the background of my window in a Qt application running on Windows 10.
Has anyone successfully implemented an acrylic effect using QGraphicsEffect, OpenGL, or any other method in Qt? If so, could you please share how you approached this, or point me to any useful resources or examples?

The acrylic effect will show some of the color of what is behind your widget. There is not much you can do on Qt's side to get that background. Otherwise you could just set a background image with the acrylic effect.

Instead, you need to get the native window handle from a Qt widget and use the Windows API to apply the acrylic effect.

IIRC there was a similar post + solution few years ago here in the forum... Maybe you are able to find it via search function.
