c++ - Can create window like C#'s TransparencyKey in Qt?

Question

I should to create window like C#'s TransparencyKey in Qt.
Normally, to make a window transparent in Qt, set the Window Color to transparent.
But, this way can't click button on background window.

Qt.WindowTransparentForInput is nearest to TransparencyKey, but It can't click button on transparent window.

Is it possible to make a window where I can press button on a transparent window, and also press buttons in the background?
