;
;
; Change History (most recent first):
;
; <SM3> 10/22/92 CSS Change some branch short instructions to word branches.
; <72> 5/14/92 KST #1027497 <JH>: #1025797,#1027497: In '__HMScanHWinResource', we
; ask TSM if the mouse is over a floating window. If it is, then
; TSM will try to locate and open the resource file to load the
; Help resources for the floating window. Balloon help now works
; when mouse is over a floating window.
; <71> 4/6/91 DTY csd, #86370: IsMouseInMenuBar popped off the incorrect number of
; bytes from the stack if it couldn<64>t get the 'MBDF' resource,
; which would happen if MenuList was nil. Check to make sure that
; MenuList contains a real handle before trying to get the 'MBDF',
; and pop off the correct number of bytes if this fails anyway.
; <70> 3/19/91 RLC ksm,#BUG.GUIDE Item #8510137 - Fix typo in FillInDialogMsg()
; that was not filling in the variant & proc numbers from an
; 'hdlg' resource from the right register offset.
; <69> 3/13/91 RLC ksm,#83253 - Change call to SaveBits() to create purgeable bits
; so that if we get short on memory, the bits we saved behind the
; balloon will get invalidated by RestoreBits(). GO5 approved.
; <68> 2/20/91 RLC ksm, #BH-TC-0076 Fix modal dialog menu balloons so that apps can
; get special balloons for menu titles and items when a modal
; dialog is up. (GO5 approved)
; <67> 2/8/91 RLC <ksm> #82161 Add the HMStripNullFromProcessName routine that
; removes leading null characters from a pstring so that Text Edit
; doesn't word break a process name in a balloon. [Change approved
; by GO5]
; <66> 2/5/91 stb gs: include MenuMgrPriv.a
; <65> 1/24/91 RLC <gbm> #81591 Change __HMFillInDialogMessage() to respect the
; resource file whether a specified resource file refnum or -1
; from HMScanTemplateItems(). If -1 then have those routines call
; GetResource() else call Get1Resource() [which means specifically
; search a resource file for a help resource].
; <64> 1/22/91 RLC <dc> #81592 Fix bug that leaves a balloon up if the mouse
; moves from a system tracked balloon to the menubar.
; <63> 1/18/91 KSM <RLC> Change include of BalloonPACKEqu to BalloonsPriv.a.
; <62> 1/14/91 RLC <ksm> Change a call to GetResource into Get1Resource when
; fetching a 'hdlg' resource as we must make sure where we're
; fetching the resource from when handling multiple help resources
; with the same ID.
; <61> 1/10/91 RLC <ksm> Fix the check of any setup DialogResID value from
; HMSetDialogResID. Fix a bug that was smashing the return value
; from a call to the HMScanTemplateItems call - this fixes a bug
; that wouldn't track a helpItem driven 'hdlg' and a
; HMSetDialogResID assigned 'hdlg' in the same dialog.
; <60> 1/3/91 RLC <vl> Fix IsBalloonChanged routine to NOT remove a balloon if
; hmgLastMenuID says that there wasn't a balloon that we put up
; ourselves (via HMShowTitleBalloon). This change will allow
; developers to call HMShowBalloon for menu titles instead of
; requiring that they have an 'hmnu' resource.
; <59> 12/18/90 RLC <ksm> Change HMStuffWindow routine to do the right thing in 32
; bit mode and to fix the bug that called _GetAuxWin on B & W
; machines.
; <58> 12/14/90 RLC <ngk> Shorten code in HMSetupBalloonRgns by fetching translation
; of varCode to balloon drawing directions from table instead of a
; giant case statement. Added check in HMFillInMenuMsg that makes
; sure we're in MenuSelect so that popups & hiearchicals menus get
; the right state message in modal dialogs (and movable modals).
; <57> 12/3/90 RLC <ksm> Fix bug that wasn't appending a menu item's mark character to
; the name to fetch when looking up a GetNamedResource item when
; filling out the help msg record in HMFillInMenuMsg.
; <56> 11/29/90 RLC <ksm> Repair the HMStuffWindowInfo code that ksm & gbm made at
; 2:00AM so that it actually works when window does NOT have an
; aux wind record.
; <55> 11/28/90 gbm (with KSM) _HMStuffWindowInfo wasn't 32-bit clean, since it
; messed directly with the window variant in top byte of the
; handle...
; <54> 11/16/90 RLC <ksm> Fix bug that was not respecting the ModalDialog state for
; Apple Menu item help messages. The enabled message was always
; displayed.
; <52+> 10/4/90 RLC <ksm> Optimization in help mgr resource walks. Fixed bug in
; GetIndHelpMsg() that was not returning the correct data in the
; case of a HMCompareItem in an 'hmnu' resource. Fix bug that
; wasn't allowing an 'hmnu' resource to have HMNamedResourceItem
; as the first item (the title balloon msg) and map 'modal dialog'
; title & item balloons to the checked and marked w/ a diamond.
; Change the 'hwin' resource scanning routine to call
; HMScanTemplateItems instead of duplicating this code (saves >
; 720 bytes).
; <52> 10/3/90 RLC Fix a bug when extracting help message data from a help resource
; that wasn't clearing the lower (upper) nibble of the pstring
; index when reaching to 'other' items.
; <51> 9/30/90 RLC Do some code reduction and change most routines to use the link
; patch macros.
; <50> 9/25/90 RLC Move the __HMExtractHelpMsg to be in the BalloonPack.p file and
; just have this routine call the __HMGetIndHelpMsg routine and
; ignore the extraneous params that are returned from this call
; (saves >370 bytes).
; <48+> 9/22/90 RLC Add a routine to resize and restuff the window variant for the
; balloon window.
; <48> 9/17/90 RLC (JSM) Fix HMCallCustomWDEFCalc that was doing a MOVE.L into the
; result instead of the correct MOVE.W instruction. This was
; causing a crash in HMShowBalloon by smashing the hiword of the
; HMGlobalPtr that was on the stack.
; <47> 9/13/90 RLC Changed name of routines to have '__' chars in front of
; procedure name (in jump table as well); Fix bug that put up menu
; title balloons in front of pulled down menu just b4 menu
; disappears; Fixed bug that was bit testing wrong bit when
; scanning 'hrct' resources for hmAbsoluteCoords (Change it to
; match Inside Mac VI doc).
; <46> 8/31/90 RLC Remove priority 2 bug that flashes ModalDialog balloons once
; when dialog first comes up, reentrant support in HMBalloonBulk,
; support for CloseView, fix process & help menu balloons when
; modal dialog is up.
; <44+> 8/21/90 RLC Add in a reentrancy test for BalloonBulk code.
; <43+> 8/20/90 RLC Repair Philip's restored old code and move in _ProcHelper
; dispatcher.
; <46+> 8/9/90 RLC Add some glue to read shift key quickly.
; <44+> 8/3/90 RLC Fix tipProc calling convention: tip,rgn,varCode.
; <43+> 7/31/90 RLC Fix bug that doesn't range check correctly in FillDialogMsg for
; offset msgs.
; <42+> 7/25/90 RLC Add code to support Easy Access and remove calls to Extract<63>
; <41+> 7/17/90 RLC Fix HMExtract routine to be 1 based and check ranges.
; <41> 7/13/90 RLC Fix modal dialog w/ enabled menu help msg case by calling new
; dialogmgr dispatcher, shortened code by calling globals
; directly, added HMScanHRCTResource routine.
; <39+> 7/6/90 RLC More changes for those modal dialog variants.
; <38+> 7/5/90 RLC Tweak some routines to make sure multiple help items are
; supported correctly.
