Change History (most recent first):
|
|
|
|
<23> 8/4/92 DCL Changing a few comments for New Inside Mac: doToggle,
|
|
teFInlineInput & teFUseTextServices
|
|
<22> 7/15/92 SMB ## <ys>: Move DoText selectors from TextEditPriv.a to here so
|
|
the whole darn world can use them instead of hard-coded
|
|
constants!
|
|
<21> 5/6/92 DCL NIIM: Added synonyms for TESetJust (TESetAlignment),
|
|
GetStyleScrap (TEGetStyleScrapHandle), SetClikLoop
|
|
(TESetClickLoop), SetWordBreak (TESetWordBreak).
|
|
<20> 4/15/92 DCL Changed TESetStyleScrap to TEUseStyleScrap
|
|
<19> 4/14/92 DCL Added new improved names in the continued pursuit of
|
|
name-nirvana in IM 2nd Edition.
|
|
<18> 4/6/92 DCL For New Inside Mac: Adding fancy new improved names for old
|
|
crusty routines. #1025005 Replaced recalBack & recalLines
|
|
with hDispatchRec in TERec.
|
|
<17> 2/17/92 MH Added better spelling SetStyleScrap.
|
|
<16> 11/8/91 JL Changed CharsPtr from a pointer to the Chars struct to a pointer
|
|
to the same type as the Chars struct. Chars is an array and
|
|
therefore a pointer to it would be a pointer to a pointer.
|
|
<15> 9/12/91 MH Add correctly spelled versions of 6 ..Style... Calls
|
|
(...Style... vs. Styl...)
|
|
<14> 7/31/91 JL Updated Copyright.
|
|
<13> 1/27/91 LN Checked in Database generate file from DSG.
|
|
<12> 11/14/90 JL Put formal parameter names back.
|
|
<11> 11/5/90 dba change TEGetScrapLen to be a #define
|
|
<10> 11/4/90 dba got rid of some extraneous parameter names; added more use of
|
|
const in parameters; change TEScrapHandle() to a #define
|
|
<9> 10/30/90 SMB Added intTextWidthHook as a new selector to the TECustomHook and
|
|
TextWidthHook as an offset into the dispatch table. Added new
|
|
feature bit, teFUseTextServices, to allow an application to
|
|
disable inline input.
|
|
<8> 10/24/90 JL Changed #Defines to anonymous enums.
|
|
<7> 6/11/90 SMB NEEDED FOR SIXPACK & 7.0: added TEFeatureFlag bit definition for
|
|
inline input, teFInlineInput.
|
|
<6> 2/13/90 SMB NEEDED for 6.0.5 - Added nWIDTHHook, IntNWidthHook for
|
|
TextEdit's new C2P routine.
|
|
<3> 1/30/90 SMB NEEDED for 6.0.5 - Adding names of FindWord callers.
|
|
<2> 1/17/90 SMB NEEDED FOR 6.0.5: Moved newTEFlags and intDispSize to
|
|
TextEditPriv.h. Added new names for TESetJust. Also added
|
|
offsets into TEDispatchRec and set/replace style modes.
|
|
<1> 12/18/90 CCH Adding for the first time into BBS.
|
|
|
|
** 1.3 smb 10/05/1989 Used Pascal comment delimitors rather than C! Oops.
|
|
** 1.2 smb 09/25/1989 Added selector for new interface, TEFeatureFlag
|
|
** 1.1 CCH 11/ 9/1988 Fixed headers and removed projector resource.
|
|
** 1.0 CCH 11/ 9/1988 Adding to EASE.
