|
||
;
|
||
; Change History (most recent first):
|
||
;
|
||
; <SM2> 10/22/92 CSS Change short branches to word branches.
|
||
; <14> 4/11/91 gbm csd, KSM, BRC#86464: Fix many references to the control
|
||
; rectangle which are invalid because the control handle can be
|
||
; unlocked.
|
||
; <13> 3/4/91 dba dty: get rid of SysVers conditionals
|
||
; <12> 12/14/90 VL (ksm) Use PaintRoundRect instead of PaintRect for dithering
|
||
; text. Also, changed PenMode to TextMode since grayishTextOr is a
|
||
; text mode.
|
||
; <11> 8/23/90 SAM Removed the MoveHHi from the DrawPBut routine so that MacApp
|
||
; will work (it assumes that handles will be ok across calls to
|
||
; DrawControl -- idiots!)
|
||
; <10> 8/17/90 dvb Change grayish textMode pnMode to txMode
|
||
; <9> 8/13/90 VL Fixed test for portVersion to avoid trashing portVersion's
|
||
; value.
|
||
; <8> 8/2/90 VL Replaced SysVers switch with UseTrueGrayText (for ROM build).
|
||
; <7> 8/1/90 VL Make text to be drawn in TrueGray when disabled (in a color
|
||
; grafport).
|
||
; <6> 6/14/90 DDG NEEDED FOR SIXPACK: Moved the control manager handle with
|
||
; _MoveHHi before we lock it down while we are drawing. This
|
||
; should prevent out-of memory problems.
|
||
; <5> 5/29/90 DDG NEEDED FOR SIXPACK: Added the proper tag to the previous
|
||
; comment.
|
||
; <4> 5/29/90 DDG NEEDED FOR SIXPACK: Fix a bug where the button title is left
|
||
; unlocked for the duration of the drawing call.
|
||
; <3> 5/1/90 DDG Removed the temporary conditionals that I added for Sys605.
|
||
; <2> 3/2/90 DDG Adding conditionals for Sys605
|
||
; <1.4> 11/17/89 dba took out checks for 64K ROMs
|
||
; <1.3> 8/22/89 SES removed references to nFiles; updated equates accordingly
|
||
; <1.2> 2/9/89 EMT added new messages for 32-bit clean Control Manager.

|
||
; <C818> 2/14/87 DAF Converted nuMac PaintRoundRgn to be unified with other Macs’

; Erase stopped setting backColor when drawing text.
|
||
; <C700> 1/26/87 DAF Universal version of ButtonCDEF.a (version 10)
|
||
; <C637> 1/14/87 DAF Changed textMode back to srcOR from srcCopy (sigh...)
|
||
; <C560> 12/21/86 DAF Added Mark Davis’ code to allow reversed checkmarks for intl
|
