I'm not 100% clear what you mean by that, but is this something like
what you want? Or have I totally misunderstood your question? (it's not
clear to me whether you are talking about a GUI button object, or
actually reading the mouse button state from your code).


int d_nostick_button_proc(int msg, DIALOG *d, int c)
{
   if (msg == MSG_CLICK) {
      d->flags ^= D_SELECTED;
      show_mouse(NULL);
      SEND_MESSAGE(d, MSG_DRAW, 0);
      show_mouse(screen);

      do {
      } while (mouse_b);

      if ((d->flags & D_SELECTED) && (d->flags & D_EXIT)) {
         d->flags ^= D_SELECTED;
         return D_CLOSE;
      }
      return D_O_K;
   }

   return d_button_proc(msg, d, c);
}
