Hi there. I need to prohibit screenshoting of my window.
Maybe there's already a code for prohibiting screenshots, maybe someone could give me link or code example?

I've found so far that the folowing funcs can screenshot:
XGetImage, XGetSubImage, XCopyArea, XCopyPlane.
Man says those funcs have some major requirements. I'm going to try to make a window that does not satisfy those requirements. May be any other ways of prohibiting screenshots?
