; ValidateMenuBar is the routine that draws the menu bar only if necessary (local or global dirty bit set)
|
|||
|
|
;
|
|||
|
|
; Note that the Process Mgr will not let the _DrawMenuBar through if we<77>re not the frontmost process.
|
|||
|
|
;
|
|||
|
|
; For the local dirty bit, we don<6F>t care, since we<77>ll get redrawn anyway when we come to the front. This
|
|||
|
|
; means we can clear it here to eliminate multiple calls to _DrawMenuBar that won<6F>t do anything.
|
|||
|
|
;
|
|||
|
|
; However, we want to only test (not clear) the global dirty bit here, which is set by DrawMBARString, since
|
|||
|
|
; we want to make sure the menu bar gets redrawn eventually no matter which app is at the front.

; To avoid problems where apps patch any of DrawMenuBar, HiliteMenu, MenuSelect (i.e., the routines
|

; herein that utilize ValidateMenuBar) and recurse forever trying to validate the menu bar, we
|
