; Contains: Standard Button Definition Procedure for the MacIntosh Control Manager
; This file contains the control definition procedures that define
; the standard "button" type controls. These include PushButtons,
; CheckBoxes, and a checkBox variant called RadioButton.

; This file is used in these builds: Mac32 HcMac MacPP BigBang Sys606
;
; 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.
; <1.1> 11/11/88 CCH Fixed Header.
; <1.0> 11/9/88 CCH adding to EASE.
; <<3C>1.1> 9/23/88 CCH Got rid of inc.sum.d and empty nFiles
; <1.0> 2/12/88 BBM Adding file for the first time into EASE<53>
; <C948> 11/8/87 DAF Updated romres sources from system disk sources
; SMAB156> 3/30/87 DAF Tested ROM version before using teSysJust.
; <C818> 2/14/87 DAF Converted nuMac PaintRoundRgn to be unified with other Macs<63>
; 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<69> code to allow reversed checkmarks for intl
; <C424> 11/18/86 DAF converted a BSET/BCLR to an HLock/HUnlock, in CalcPBut
; <C407> 11/16/86 DAF changed textMode (again) to srcCopy, as per Cary<72>s
; recommendation
; <C203> 10/8/86 DAF updated color support on nuMac for RGBColors changed textMode to
; srcOr.
; <C59> 6/30/86 DAF added color support for nuMac (mucho chango)
; <v4> 8/26/85 EHB made variable sized fonts work (ROM85>0 only)
; <v3> 5/20/85 EHB implemented Multi-Line buttons
; <v2> 5/16/85 EHB only return "254" if point in control!
; 3/12/85 JTC changed occurrences of LGlobals to GrafGlobals
; 2/14/85 JTC added res name
; 1/14/85 JTC convert to MDS
; 12/31/83 AJH made text of checkBox/radioButtons grayed out if disabled
; 10/17/83 AJH back to "gray-out" button disabling
; 10/12/83 AJH changed button disabling
; 9/27/83 AJH made variants > 7 not force the system font
; 8/29/83 AJH fixed scrambling bug in CalcPBut
; 6/7/83 AJH fixed scrambling bug, changed check draw for new QuickDraw
; 4/4/83 AJH made it force size 12 for text
; 4/1/83 AJH made it use hardwired gray
; 3/27/83 AJH made it respect initial clip in button drawing
; 3/11/83 AJH fixed up check box drawing
; 12/28/82 AJH Put button definitions in their own file
; 11/16/82 AJH Made branch tables offset based
; 11/14/82 AJH Improved PushButton roundness scaling; removed box in arrowBits
; 10/17/82 AJH Made controlProcs preserve A1
; 10/10/82 AJH Converted for QuickDraw Trap Interface
; 10/5/82 AJH Fixed checkBox flashing, added code saving optimizations
; 10/3/82 AJH Fixed bug in scrollBar positioning -- wasn<73>t ctl relative
; 9/29/82 AJH Added CheckBox control definition procedure
; 8/29/82 AJH Added "255" hiliting,
; 8/25/82 AJH Fixed corner-clobber bug in pushButProc
