;
|
|
; Change History (most recent first):
|
|
;
|
|
; <SM3> 10/6/92 PN # 1040150 Get rid of Sysvers conditionals and bring the code to
|
|
; the current state (7.1)
|
|
; <16> 7/15/92 SMB ## <ys>: Move DoText selectors from here to ToolEqu.a (and
|
|
; Pascal/C equates) so the whole darn world can use them instead
|
|
; of hard-coded constants!
|
|
; <15> 9/15/91 YS Defined an offset to a byte in TEDispatchRec (lastscript), to be
|
|
; used by the split/single caret stuff. <15-YDS-8/27/91>
|
|
; <14> 8/26/91 JSM Cleanup header.
|
|
; <13> 2/14/91 SMB pke,#70628 - removing ForwardDeleteChar for now.
|
|
; <12> 2/1/91 SMB pke,#82169: Removing MetricsFrame. Renamed leftSide to
|
|
; leadingEdge in P2CFrame record. Added WidthRemaining to
|
|
; P2CFrame.
|
|
; <11> 1/14/91 SMB (jdt) Added forwardDeleteChar. Added MetricsFrame for
|
|
; _OutlineMetrics call in TextEdit.
|
|
; <10> 10/30/90 SMB Adding hasTextWidthHook conditional for the code changes
|
|
; supporting the new TextWidthhook. Also added hasBufferingFix for
|
|
; the code changes supporting the bug fixes for the text buffering
|
|
; feature. Increased size of TEDispatchRec, intDispSize, and moved
|
|
; frame for TextBox into here.
|
|
; <9> 9/11/90 SMB Added an equate, defBufSize, that was hiding deep in the bowels
|
|
; of InsertRecal! Also moved HiliteFrame here.
|
|
; <8> 6/11/90 SMB NEEDED for ROM builds: SysVers not defined for ROM so
|
|
; hasInlineInput flag must be set explicitly. Oops!
|
|
; <7> 6/11/90 SMB NEEDED FOR SIXPACK AND 7.0: added hasInlineInput conditional for
|
|
; Inline Input support.
|
|
; <5> 3/21/90 SMB NEEDED FOR SS-6.0.5: Fixing FmtOrderFrame to include LRTextFlag
|
|
; field for compatibility with the ROM.
|
|
; <4> 2/13/90 SMB NEEDED FOR 6.0.5 - removed teLFlush, teRFlush, and teCenter.
|
|
; Increased size of DispatchRec to allow for nWidthHook.
|
|
; <3> 1/30/90 SMB Needed For 6.0.5 - -Moved names of FindWord callers into
|
|
; ToolEqu.a. -Adding private equates and frames here and removing
|
|
; them from TextEdit.a.
|
|
; <2> 1/16/90 SMB Fixed comment in header.
|
|
; <1> 1/9/90 SB first checked in. Moved private definitions at end of
|
|
; TEDispatchRec here. Increased size of TEDispatchRec.
|
|
; NEEDED FOR 6.0.5: Moved newTEFlags and intDispSize here
|
|
; from ToolEqu.a. Also added TwoByteCharBuffer at end of
|
|
; TEDispatchRec since need it local for each TE record.
