Change History (most recent first):
<60> 10/30/92 DTY Use Get/Set macros to access ExpandMem.
<59> 8/4/92 KST #1038311 <gbm>: <HA>: Undo the previous fix and put the fix in
ScriptMgr:ScriptMgrKeyGetSet.a
<58> 8/1/92 KST #1038311 <JH>: Documentation change.
<57> 8/1/92 KST #1038311 <JH>: Can't call FixTSMDocument() to the app. in the
SetDefaultInputMethod() either.
<56> 7/31/92 KST #1038311 <JH>: In xCloseServiceWindow(), make sure the window
that we are going to close is not nil and it is truely a
floating window.
<55> 7/27/92 KST #1037539 <JH>: Return tsmScriptHasNoIMErr instead of
tsmUnknownErr in SetDefaultInputMethod() and
GetDefaultInputMethod() to match the ERS.
<54> 7/8/92 KST #1033475 <JH>: In SetTextServiceLanguage(), when we activate an
input method, make sure we are not using old JIM.
<53> 7/6/92 KST #1033507,1033505 <JH>: Don't change the tsmScript/Language if
utOpenIM4Document() failed.
<52> 6/30/92 KST #1030903,1033475 <smb>: We had an agreement with the keyboard
menu code that TSM will call SetScript(false) in
SetDefaultInputMethod().
<51> 6/30/92 KST #1033456 <JH>: If utJustDeactivateIM4Document() returns
DocNotActiveErr, then ignore the error.
<50> 6/26/92 KST #1033450,1033456,1031316 <JH>: utCloseIM4Document() will now
take an extra parameter to indicate if it should send
HidePallete() command to input method. Only set it to true when
called in SetDefaultInputMethod().
<49> 6/22/92 KST #1030843 <JH>: When there is no current active document, and
switch from old JIM to TSM-styled input method, need to reset
UseOldJIM flag.
<48> 6/17/92 KST #1030843 <JH>: For the previous fix, in xUseInputWindow, there
is a possibility that the current active document could be nil.
Need to check that.
<47> 6/17/92 KST #1030843 <JH>: Changed the function name from
utaIsApplicationTSMAware to utaIsAppTSMAwareAndNotUsingIW to be
more precise and descriptive.
<46> 6/14/92 KST #1032466 <JH>: Fixed the bug when running a TSM aware
application in Roman primary script, select SJip and then Akiko,
Akiko is not activated.
<45> 6/13/92 KST #1031142,1030881 <JH>: When user turns UseInputWindow off and
the current active document is SWM's, then need to call
FixTSMDocument before deactivating that document.
<44> 6/10/92 YK #1031298 <JH>: Make sure that the default input method exists.
<43> 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. This involved many
many changes.
<42> 6/10/92 KST #1031634, #1031924 <JH>: Fixed the bug -- "Balloon Help is broken
causing the system to crash as menus are pulled." in FindServiceWindow.
<41> 6/2/92 JH #1028635,1030481,1030631,1030634,1030647 <KST>: Adding a check
in FindServiceWindow for a nil menulist handle in low memory.
FindServiceWindow gets called a lot now by input methods at odd
times, and if the menulist low-mem has nil in it (yes, it can)
the normal FindWindow call crashes trying to jump to an MDEF
proc referenced off of nil. So we check here. If it is nil we
just return indesk.
<40> 5/20/92 KST Ooops, I added a comment which had syntax error.
<39> 5/20/92 KST #1030422 <JH>: Fixed a bug in SetDefaultInputMethod.
<38> 5/19/92 KST #1029247 <hsK>: GetDefaultInputMethod, SetDefaultInputMethod,
and SetTextServiceLanguage routines should check if user is
passing the correct language code corresponding to the script
code.
<37> 5/13/92 JH <KST>: Fixing NewServiceWindow so that it marks floating windows
with the proper windowkind.
<36> 5/8/92 KST When we switch from non-CJK script to TSM-styled IM, we must
clear the ScriptMgr's secret "UseOldJapaneseIM" flag.
<35> 5/6/92 KST #1028642,<JH>: Fixed the bug: "floating pallete stays when
switch from Akiko to Roman in TSM aware application".
<34> 5/1/92 KST #1028301,<JH>: SetTSMDialogState, RestoreTSMDialogState,
TSMChangeCursor, TSMRestoreCursor calls are no longer needed and
should be removed from the source code.
<33> 4/9/92 KST JH,modifying xNewServiceWindow to mark a falg in refcon. Adding
stuff to support SWM as a driver. We don't need
xSetTSMDialogState and xRestoreTSMDialogState call anymore. Will
remove them in the next release.
<32> 3/30/92 KST JH, 1025008, 1025009. First attempt to solve the pallete/menu
bar flickering problem. Also, we synchronize the keyboard menu
with the script of the TSM document.
<31> 3/23/92 KST Code changed according to the comments from the code review.
<30> 3/18/92 KST In "xSetTextServiceLanguage", if user switches key script, then
I'll call FixTSMDocument.
<29> 3/12/92 KST Make sure handles are locked properly.
<28> 3/6/92 KST In "xSetTextServiceLanguage", when user switches input method,
if there is currently an active document which belongs to SWM,
then send an AE to ask her to close the input window.
<27> 3/2/92 KST In "utOpenActivateDefaultIM" and "utOpenIM4Document", it now
takes a Boolean flag to indicate if we should activate the input
method.
<26> 2/28/92 KST Added 2 new calls "SetTSMDialogState", and
"RestoreTSMDialogState".
<25> 2/11/92 DCL Changed the name of TSMEqu.[aph] to TextServices.[aph] for
better read-ability.
<24> 2/10/92 KST Moved all internal routines to TSMInternalUtil.c file.
<23> 2/10/92 KST Change the default input method resource format, we don't store
script code now. Script is implied by array index. Instead, we
store the old IM FEP ID in the resource record.
<22> 2/3/92 KST If we switch from old to new input method, need to check if we
are coming from old JIM and need to inform Process Manager.
<21> 2/1/92 KST If there is no active document, we still need to inform PM
whether to use SWM or not.
<20> 2/1/92 KST We don't have a global flag in TSM globals to indicate using
bottom-line window.
<19> 1/31/92 YK with KST: Added xFindServiceWindow.
<18> 1/31/92 KST Update the input method table in the TSM global in
"xGetDefaultInputMethod".
<17> 1/31/92 KST Activate SWM only if we are not using old Japanese Input Method.
<16> 1/29/92 KST Input method synchronized with the script/language only when the
correct environment has been set up in SetTextServiceLanguage.
<15> 1/16/92 KST When we search for a default input method, need to set the mask
field to search for the correct script.
<14> 1/15/92 KST GetDefaultInputMethod should not open the input method.
<13> 1/13/92 YK Put comments. Call GetToolTrapAddress instead of GetTrapAddress.
<12> 1/13/92 KST Activate SWM only if we can open the default input method.
<11> 1/11/92 KST Call Process Manager's "RouteEventToSWM" routine only if
P.M. has been loaded.
<10> 1/11/92 KST Adding code to support SWM Background application.
<9> 1/10/92 KST Call "LoadResource" if the resource handle points to nil.
<8> 1/9/92 KST In "UseInputWindow", If idocID == 0, it affects only one (••
current ••) application, not the whole system.
<7> 1/8/92 KST In xGetDefaultInputMethod, if the default input method is not
loaded in the system, another input method is opened by query
Component Manager.
<6> 12/31/91 KST We now save default input method and "UseInputWindow" flag in
resource file across reboot. A new scheme is adopted to allow a
single document to use input window.
<5> 12/20/91 KST Making progress toward Alpha. Changed "inline" to "TSM".
<4> 12/10/91 KST Adding new code for the D5 build.
<3> 11/26/91 YK Added code for the floating window.
<2> 11/23/91 KST Check in the first time for Cube-E.

b). I.M. is different: User wants to switch to a different script and also changes the default I.M.
I need to close the old I.M. for that script, set the default,
and then call "xSetTextServiceLanguage".
4. And of course for each case, we need to consider if the Japanese is using old input method.
