It’s obviously not just a topmost transparent window given it displays even on top of fullscreen DirectX, but I can’t seem to figure out the right Windows APIs to use to make a similar overlay. 13/03/2018 at 10:29 #7994 Grant [Tobii]Moderator Hi @wildpeaks, Thanks for your interest! Yes, it’s a very cool piece of code for sure 🙂 The program was made in DX11 and C++, but you can get a good idea of the implementation strategy at the following link @ https://stackoverflow.com/questions/31313624/click-through-transparent-window-no-dragging-allowed-c Hopefully this points you in the right direction.. please let us know! 13/03/2018 at 10:46 #7996 Cecile MullerParticipant Thanks 🙂 Author Posts Viewing 3 posts - 1 through 3 (of 3 total) You must be logged in to reply to this topic.
