|
;
|
|
; Change History (most recent first):
|
|
;
|
|
; <SM2> 11/6/92 SWC Changed PackMacs.a->Packages.a.
|
|
; <1> 10/1/91 JSM first checked in
|
|
; <0> 10/1/91 JSM Created from StandardFile3.LDEF.a.
|
|
;
|
|
; Modification history from StandardFile3.LDEF.a below:
|
|
;
|
|
; <14> 12/13/90 ngk <KSM>now gray disabled icons in color window on 1-bit monitor
|
|
; <13> 10/29/90 ngk Now gray out icons of disabled items.
|
|
; <12> 9/17/90 ngk change _PenMode to _TextMode to sync with changes to gray text
|
|
; also have a hack to set TextMode back to srcOr.
|
|
; <11> 8/17/90 gbm make grayishTextCopy into grayishTextOr
|
|
; <10> 8/11/90 ngk fix bug where it could trash rowBytes of a B&W grafport
|
|
; <9> 8/5/90 ngk Use trueGray for drawing dimmed text. repack FileEntry. use rgb
|
|
; array instead of pltt for colorized icons.
|
|
; <8> 7/2/90 ngk Now use hilite color for selecting items. Added color to icons.
|
|
; The userHandle of the listrec is assumed to contain a "palette",
|
|
; and each file entry contains the index into the table. It does
|
|
; not use the palette manager, just the stucture for holding a
|
|
; list of colors.
|
|
; <7> 6/6/90 ngk reduced include files
|
|
; <6> 5/2/90 ngk include IntlUtilsPriv.a
|
|
; <5> 4/11/90 ngk fix plotMini bug if SICN not found
|
|
; <4> 3/18/90 ngk Fix 68000 bug of hilite on draw not working.
|
|
; <3> 3/5/90 PKE Added smTruncEnd as truncWhere parameter for TruncString call,
|
|
; since TruncString interface now matches former NTruncString
|
|
; interface.
|
|
; <2> 2/25/90 ngk Added ability to put icon of left or right, and justify text
|
|
; <1> 2/17/90 ngk Made into real stand-alone LDEF
|
|
;
|
|
; 1.8 ngk 11/14/1989 Changed FileEntry to be a real record.
|
|
; 1.7 ngk 11/08/1989 fixed bug where incorrectly test data len often caused missing items
|
|
; 1.6 JRM 10/30/1989 changes because script and style are part of in file
|
|
; record
|
|
; 1.5 ngk 09/13/1989 fixed bug where you could select a dimmed item
|
|
; fixed bug where incorrectly test data len often caused missing items
|
|
; 1.4 JRM 08/11/1989 Add back in 604 conditionals that Darin said I could
|
|
; take out
|
|
; 1.3 JRM 08/08/1989 7.0d10 release
|
|
; 1.2 JRM 06/08/1989 sf conditionals for bigbang and 604
|
|
; 1.1 JRM 06/05/1989 big bang standard file - see StandardFilePACK.a
|
|
; 1.0 CCH 11/16/1988 Added to EASE.
