1) Yes, color1 == color2, can i get rid of the pixmapbutton-highlighting
behavior?
2) oh.. :( i used
Display *disp=fl_get_display();
then use DisplayWidth(disp) or DisplayHeight(disp) :/
Another thing: how can I force-update a canvas? I added a callback for
Expose events, which redraws the whole thing (it's a clock, i didn't like
the default XForms clock). now i redraw it by
fl_hide_object (canvas);
fl_show_object (canvas);
This works, but it flashes terribly. Now I would like to have another
callback (maybe MouseEntry?) do a different sort of update (erase the
hands, redraw them, instead of everything) but how do I trigger this
manually?
