Sorry to come in late her, but Ian is right, the lParam is the WIN32 way to do just this. The FLTK function has no extra parameter simply because no other pointer is provided by the underlaying system architecture, and the user may actually use lParam for something entirely different. It would be wrong to provide something that looks like a pointer and actually contain the x and y mouse coordinates.
