You can access a pointer to the window within the button callback by setting the second argument of the button callback function as a pointer to the window. This tecnique is explained in the 'Hint' described here: http://www.fltk.org/doc-1.1/common.html#4_9 #include <fltk/run.h> #include <fltk/Window.h> #include <fltk/Button.h> using namespace fltk; void cb(Widget *w,void *d){ Window *win=(Window*)d; win->hide(); } int main(void){ Window a(400,400,"Window"); a.begin(); Button b(0,0,200,200,"Hide"); b.callback(cb,&a); a.end(); a.show(); return run(); } _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
