FlashMenuBar
FlashMenuBar Invert one menu title or entire menu bar
#include <Menus.h> Menu Manager
void FlashMenuBar(menuID );
short menuID ; ID of menu title; 0=invert entire menu bar
You can use this to invert an individual menu title or to invert the entire
menu bar. Call it twice to actually "flash" a title or menu bar.
menuID is your internal ID for a menu (if created via NewMenu) or the
'MENU' resource ID of a menu (if read in via GetMenu or
GetNewMBar). If menuID =0 (or any invalid menu ID), then the
entire menu bar is inverted.
Returns: none

Notes: Since the HiliteMenu function does this for any individual menu title, the
only reason you might need this is if you wish to attract the user's attention
before installing an entirely new menu (see GetNewMBar, GetMenuBar,
and SetMenuBar).
