Hi Josh,
Admittedly this isn't obvious from the documentation, but windows
should be destroyed this way:
AG_ObjectDetach(win);
Detached windows are automatically freed by the event loop, so calls
such as AG_ObjectDestroy() or free() must not be used. To pass a
pointer to the window to your event handler routine:
AG_ButtonNewFn(win, 0,
"Button Function", Button_Function, "%p", win);
static void
Button_Function(AG_Event *event)
{
AG_Window *win = AG_PTR(1);
AG_ObjectDetach(win);
}
