View Full Version : Displaying a QT Widget on / overlaying a 3rd Party Window (in Windows)

5th June 2013, 11:07
This is not something I have tried before and am a complete newbie to the likes of HWND, hooking etc.

Basically, I would like to display / overlay a QT Widget on top of a window of a 3rd party application (which I have no control over, I only know very basic information like window title / caption and its class name) and I have absolutely no idea how one would go about this.

I also want the QT Widget to remain in its relative location to the window of the 3rd party application, even if that window is moved around the screen.

Any help in how to get started with this would be much appreciated.
