To do that, you have to use the OS API. That's true on Linux, MacOS and EVEN Windows : "#WM_MOUSEMOVE" is part of Windows API.OrangeJuice wrote: A major problem is the fact that you have no way of getting events you would require windows constants for, like #WM_MOUSEMOVE, #WM_LMB, etc.

If your GUI consists only of PB gui components that is fine, but if you drawing part of your Window yourself i would stay away.
