   Get the window coordinates when you clic on the OpenGL window
  Hi,i want to get the window coordinates of an Opengl window when you clic on it with the mouse.Is that a question about c, c++ or win API programming or it involves Opengl?   
  Check out: http://www.gamedev.net/community/forums/topic.asp?topic_id=364041   ;  It's a Windows question. C/C++ provides the interface and OpenGL is just incidental.The simplest way is probably to call GetCursorPos() followed by ScreenToClient(), to translate it from screen coordinates. Of course, you'll want to do this when the mouse is clicked. There are a few ways to detect the click, the WM_LBUTTONDOWN message being an obvious candidate.RegardsAdmiral
