I do not quite understand the question.

  The repaint should occur here.

   Are you reading input from the user in the EntryMenu call?  As I
recall, you are using SLang's getkey functions.  If so, you may be
able to establish a interrupt handler such as the following.  But
without seeing the details of EntryMenu, it is hard to give more
specific advice.

   static int getkey_interrup_hook (void)
   {
      if (Screen_Size_Changed)
        {
           SLtt_get_screen_size ();
           SLsmg_reinit_smg ();
           Screen_Size_Changed = 0 ;
	   repaint_screen ();
        }
      return 0;
   }

        .
	.
	.
   int main (int argc, char **argv)
   {
        .
      /* perform initializations */
        .
      SLang_getkey_intr_hook = getkey_interrup_hook;
      
      main_loop ();
        .
	.
   }
