Why check menu item always return FALSE ?

["jacky618 jacky618" <hhd618 hotmail com>]

Hi, 
 I have made a check menu with Gtk+, however, it always returns FALSE:

   if (GTK_CHECK_MENU_ITEM(ckMnItem)->active == TRUE)
   {
	fprintf(stderr,"TRUE: linkage_toggled!\n");
   }
   else
   {
	fprintf(stderr,"FALSE: linkage_toggled!\n");
   }

 Why, how can I get "TRUE: linkage_toggled!\n"?

regards,
Brook.
