;
; Change History (most recent first):
;
; <53> 7/27/92 KST #1037539 <JH>: The _PaintBehind patch should only be called if
; the Process Manager has been booted.
; <52> 7/21/92 KST <JH>: Changed comments for CloseTSMAwareApp().
; <51> 7/16/92 KST #1034952 <Kda>: Let input method to set the cursor in TSMEvent
; call().
; <50> 7/15/92 KST <hsK>: Changed the release version to 1.0. Will not affect the
; functionality.
; <49> 7/3/92 KST <JH>: Correct a type error: kIMJustSetCursorBit should really be
; kSWMJustSetCursorBit.
; <48> 6/26/92 KST #1031142 <JH>: When the application claims not TSM aware any
; more, we need to clear all UseInputWindow flags so it will not
; be reused when another TSM aware app is launched.
; <47> 6/26/92 KST #1033450,1033456,1031316 <JH>: When XCLOSETSMAWAREAPPLICATION()
; is called, we better inform Process Manager about it.
; <46> 6/22/92 KST #1033280,1033495 <JH>: When part code <= inSysWindow, return not
; over a floating window. (I used to only check inDesk).
; <45> 6/19/92 KST #1032492 <JH>: When TSM tries to open the resource file using
; the refcon in the floating window, need to verify its
; windowkind.
; <44> 6/17/92 KST #1030843 <JH>: If we click in a popup menu inside of a floating
; window, HMGetBalloon needs to return true so that balloon will
; be removed. Also changed the function name from
; utaIsApplicationTSMAware to utaIsAppTSMAwareAndNotUsingIW to be
; more precise and descriptive.
; <43> 6/14/92 KST Changed utaRemoveDocumentID to return the number of TSM
; documents remained open by the application.
; <42> 6/10/92 YK Oops, don’t do last minutes change.
; <41> 6/10/92 YK #1031298 <JH>: Add OldJapaneseInputMethodExists. It returns
; True if the specified old-input method exists.
; <40> 6/10/92 KST #1031142,1030881 <JH>: Since we removed the docID param from
; TSMEvent, UseInputWindow has been broken because keydown event
; is routed to SWM recursively. Fix it with a TSM global keeping
; track of which doc is using the input window. And added a new
; private call for SWM -- TSMEventFromSWM. The TSM boot code has
; been modified so that it can handle multiple TSMinit files.
; (Global will not be re-allocated).
; <39> 6/4/92 JH #1031574 <KST>: _HMGetBalloonPatch leaves bits behind when a
; help window is drawn over the menubar. Checking to see if we are
; over the menubar or over a systemwindow before we return false.
; <38> 6/2/92 KST <JH>, Should not check for inContent in HMGetBalloon.
; <37> 6/2/92 KST <JH>,The previous change has a minor mistake in HMGetBalloon
; patch.
; <36> 6/2/92 JH #1028635,1030481,1030631,1030634,1030647 <KST>: Added SystemMenu
; patch to support system menus for input methods.
; <35> 5/20/92 KST #1030447 <JH>: Fixed a bug. UseInputWindow did not work if we
; want to have global effect for the application.
; <34> 5/14/92 KST #1025797,<JH>: Added one new message selector 'kMsgHelpHELPMgr'
; to InformTSM. This call is used by __HMScanHWinResource in
; BalloonPACK.a. Also patched __HMGetBalloonPatch so that Help
; balloon will not flash in the Finder.
; <33> 5/4/92 KST #1025252,<JH>: Patched _PaintBehind so that floating windows
; will be updated correctly when the whole screen is redrawn.
; <32> 5/2/92 YK Flush the parameter on the stack before return to a caller.
; <31> 5/1/92 KST #1027482,<JH>: If input method changed cursor in a floating
; layer, then don't let other application to change the cursor
; again.
; <30> 5/1/92 KST #1028301,<JH>: SetTSMDialogState, RestoreTSMDialogState,
; TSMChangeCursor, TSMRestoreCursor calls are no longer needed and
; should be removed from the source code.
; <29> 4/9/92 KST JH,modifying InitTSMApplication to support the fact that SWM is
; no longer an application but a driver. Adding 2 new messages in
; InformTSM. Will remove SetDialogState in the next release.
; <28> 3/27/92 KST Documentation changes.
; <27> 3/23/92 KST Changes due to the code review.
; <26> 3/12/92 KST Added a new call "utaGetTSMAwareDocTable".
; <25> 3/6/92 KST Removed debugger code. Will grow internal table when overflow.
; <24> 3/4/92 KST Get trap address of SetCursor at INIT time.
; <23> 3/3/92 KST Added 2 new calls: "TSMChangeCursor", and "TSMRestoreCursor".
; <22> 3/2/92 KST Added a private TSM call "NewTSMDocument4SWM".
; <21> 2/28/92 KST Added 2 new calls "SetTSMDialogState", and
; "RestoreTSMDialogState".
; <20> 2/27/92 KST In utKillTSMAwareApplication, if the app is not TSM aware, we'll
; send an AE to SWM ask it to close its input window. If it is TSM
; aware, we'll set tsmKillApplicationP flag to true.
; <19> 2/11/92 DCL Changed the name of TSMEqu.[aph] to TextServices.[aph] for
; better read-ability.
; <18> 2/10/92 KST InformTSM's msgChangeToOldJIM now takes a parameter -- FEPID.
; <17> 2/1/92 KST We don't have a global flag in TSM globals to indicate using
; bottom-line window.
; <16> 1/31/92 YK Added FindServiceWindow.
; <15> 1/29/92 KST Removed "xIsApplicationTSMAware" call. Also inform Process
; Manager whether it should start sending events to SWM when SWM
; informTSM with its PSN.
; <14> 1/16/92 KST Add a new message to InformTSM: kMsgChangeToOldJIM.
; <13> 1/11/92 KST TSM globals are initially cleared.
; <12> 1/10/92 KST Inform Process Manager if the application is TSM aware.
; <11> 1/9/92 KST Changed SetDefaultInputMethod selector back to 13 so that we can
; build TSM INIT with d13.
; <10> 1/8/92 KST Removed CleanUpTSMAwareApp routine. CleanUpTSMApp is now a
; message to InformTSM.
; <9> 1/4/92 KST Add a new routine "CloseTextService". Also "OpenTextService" now
; returns component instance to the caller.
; <8> 12/31/91 KST Added "CleanUpTSMAwareApplication" and "InformTSM" new calls.
; Check saved resource for "Use Input Window" global flag at boot
; time.
; <7> 12/20/91 KST Making progress toward Alpha. Changed "inline" to "TSM", and
; added new calls.
; <6> 12/10/91 KST Adding a new "InlineAwareRegister" call.
; <5> 12/10/91 KST Disable the Gestalt call for now.
; <4> 12/10/91 KST Added boot time initialization code, and to use "TSMPrivate.a".
; <3> 11/26/91 KST Low level TSM routines are now dispatched directly to the
; Component Manager.
; <2> 11/23/91 KST Check in the first time for Cube-E.
