Hello everyone, I hacked some more event handling into the W32 version of GRX: - GR_SIZE_CHANGED: Tell the program that the size of the GRX window was changed from outside - GR_OS_DRAW_REQUEST: Let the program know that the OS wants the program to redraw its window. (Normally, GRX handles this in the background, but if you use non-GRX output such as OpenGL in parallel, this can be useful.) - GR_COMMAND: Events that come from, e.g., a menu rather than the keyboard or mouse directly Patch attached.
