|

; Change History (most recent first):
|
||
;
|
||
; <SM8> 12/18/92 CSS Update from Reality:
|
||
; <19> 12/17/92 JSM Fix some StdFilter bugs relating to cursor tracking over edit
|
||
; text items, use dlgFlagsByte and bits equates consistently, and
|
||
; add comments about some non-obvious implications of calling
|
||
; ClaimEvent in StdFilter.
|
||
; <SM8> 8/28/92 CSS Update from Reality:
|
||
; <18> 8/25/92 DTY Save D3 in StdFilter to make Tom happy.
|
||
; <SM7> 7/29/92 RB The routine GetWindowModalClass calls GetResInfo on a WDEF,
|
||
; which when it ROM is not found to belong to any resource map
|
||
; anymore. The problem here is that the Installer comes later on
|
||
; and finds ResErr set to resNotFound, forcing the Installer to
|
||
; bail out from an installation even tough there is no real
|
||
; problem. To avoid this problem, we set ROMMapInsert to true
|
||
; before doing the GetResInfo on the WDEF, which may be in ROM.
|
||
; <17> 6/11/92 JSM Roll-in changes from SuperMario so this file can be used in the
|
||
; ROM build: rename ROMFrameOut and ROMClaimEvent ROMBinds to
|
||
; FrameOut and ClaimEvent to match DialogMgr.a in the ROM.
|
||
; <16> 3/31/92 KSM #1021993,<DTY>: Exported CitationsCH call - now returns OSErr
|
||
; (for dispatcher). Created new calls: Cite4 for easy-of-use, and
|
||
; the fully generic CitationsSH.
|
||
; <15> 3/6/91 dba handle NIL event passed into GetNextUserCancelEvent
|
||
; <14> 3/5/91 dba csd, #dba030501: fix GetUserCancelEvent
|
||
; <13> 1/14/91 dba (ksm) Add IsUserCancelEvent and GetUserCancelEvent.
|
||
; <12> 12/14/90 dba <JDR> call it DialogDispatch instead of DialogMgrDispatch
|
||
; <11> 12/3/90 RLC <ksm> Get rid of Is≈WindowModal routines and replace them with a
|
||
; GetModalClass and GetFrontModalClass routines.
|
||
; <10> 11/13/90 KSM <dba>Make 32-bit clean...
|
||
; <9> 10/29/90 KSM <ngk>Use emulateOrigFilterBit to emulate ROM filter proc, but with
|
||
; bug fix.
|
||
; <8> 10/29/90 ngk <KSM>add ROM bind for portable
|
||
; <7> 10/29/90 ngk <KSM>roll in new StdFilterProc and related functions to dialog
|
||
; dispatch
|
||
; <6> 7/13/90 RLC Provide an interface for Push/Pop MenuState for Help.
|
||
; <5> 7/2/90 KSM Add interface to the new standard filter proc.
|
||
; <4> 6/8/90 KSM Fix stack frame for IsFrontWindowModal.
|
