It's unnecessary and slows things down! ; <50> 7/15/92 SMB ## : Renamed DoText selectors: teMark is now teHighlight and ; teLoc is teCaret. ; <49> 7/8/92 PKE Fix up previous comment (I was too quick with the Return key). ; <48> 7/8/92 PKE #1035214 : We would like to fix DoSearch so that it always ; exits by calling FreeFmtOrderArray at exit, which will dispose ; of any fmtOrdering handle and clear ExpandMemRec.emFmtOrderHFlag ; which says that the handle is valid. This will prevent ; subsequent calls from thinking they have a valid handle before ; they actually allocate one. However, this fix is too risky; so ; instead we modify DoText to always clear the flag so that no ; routine thinks it has a valid handle when it doesn't. The more ; correct fix is in TextEdit.a. ; <47> 7/7/92 PKE #1030684 : TEGetPoint failed in unstyled multiline text if ; a R->L script was present because in this case DoMeasure ; measured from the beginning of the buffer, not the beginning of ; the current line. Fixed. ; <46> 6/23/92 SMB #1029263,: Now checking the script's 'itlb' flags to ; determine if the keyboard and font should be synchronized. ; <45> 4/27/92 DTY Get rid of hasSplineFonts conditionals. ; <44> 4/3/92 YS #1025998, in TextBox, when trying to find the right line highet ; in systems that use associated font (see <43>), saving and ; restoring of the font saves a LONG (instead of a word) creating ; the problem of loosing the port font. Another connected problem ; was the way Script Manager handeld those privete verb calls in ; the roman. This was fixed in the Script Manager. <44-YDS-4/2/92> ; <43> 2/6/92 YS #1014691, Cube-E, In the old days, the Hebrew/Arabic extention ; used to calculate the highet of a script font as Max(script font ; size, associated font size). The problem with that is that if ; you use style runs, like styled TE & WP's, you can't get the ; real size of of a script font, and you allways have the ; associated font size in it. The universal one byte init no ; longer handles it. TE will calculate it itself if it is: 1) ; unstyled text. 2) script font. 3) Has associated font (other ; then 0). In this file we do a 'come from' patch to GetFontInfo, ; one patch is from TextBox and the other is from GetSize ; <43-YDS-2/6/92> ; <42> 2/4/92 YS #1015382, Cube-E, don't redraw the whole line for a left 2 right ; system when justification is teForceLeft. <42-YDS-2/5/92> ; <41> 1/30/92 YS #1018683, Cube-E: TextBox should handle #teForceLeft correctly ; and not set it to #teJustLeft allways. Had to add a ptchTextBox ; for that. <41-YDS-1/30/92>. ; <40> 1/13/92 PKE #1019673, Bruges: Unstyled TE should not sync the keyboard at ; all for smEastEurRoman script. ; <39> 12/17/91 PKE #1017647: Fix keyboard synchronization in unstyled one-byte ; non-Roman text. For bidi scripts: don't synchronize control ; chars and L-R numbers, set keyboard to Roman for other L-R ; chars, and sync keyboard to font for R-L chars. For other ; scripts: sync keyboard to font for script letters, set keyboard ; to Roman for Roman letters, and don't sync anything else. ; <38> 12/12/91 DCL #1009157: Changed a Tst to Tst.b so as not to test the potential ; garbage in the other byte. Changed procedure noClickProc in ; TextEdit.a, StyledTextEdit.a, and TextEditPatchIIciROM.a ; <37> 11/12/91 SMB #1014705 - for CubeE and Bruges - Keyboard and font synch'ing ; isn't correct for punctuation and numbers: TE allows a Roman ; keyboard & a non-Roman font combination for ascii characters and ; european characters (or high ascii chars.) and it should also ; allow this for numbers and punctuation marks. This was reported ; against the Eastern European systems. Actually, this code will ; be optimized to only allow this unsynchronized state for 2-byte ; text. See ClickKeyboard2Font. Also fixed the synchronization of ; unstyled text cases in TEClick and TEKey. ; <36> 9/30/91 YS Used to syncronize the keyboard wrong for L->R scripts ; (unstyled) when was backspacing a selection (and not a single ; delete), d6 wasn't set up corectly. use teSelStart(a3) instead. ; (bug #1013159) <36-YDS-10/1/91> ; <35> 9/23/91 PKE For Cube-E (and Bruges): If non-Roman scripts are installed, ; TEInit should no longer set TESysJust to its idea of system ; default, since users can now set the default. Also: Define ; forLocalizability here if it is not defined in BBSStartup. ; <34> 9/13/91 YS Moved in 6.1 fixes for a Localizable 7.0.1 (forLocalizability) ; <34p> Fix the wrong placment of the caret for one blinking cycle ; when changing a language and typing a char. (bug #1006971) ; <34p-YDS-9/2/91> <34o> Fix the problem of the arrow keys not ; functioning in a L->R system, with line direction R->L (bug ; #1007934) <34o-YDS-9/2/91>. <34m> when backspacing, synch the ; keyboard to the right language even for unstyled (single byte ; only). (bug #1006972) <34m-YDS-9/2/91> <34l> Fix the Big cursor ; bug, this is NOT the old big applelink cursor bug (fix YSD ; <3.1>). In the case where the cursor is on a line start, we used ; to fall into the single caret code ; (but we didn't have any split caret !!!), so while switching ; the cursor rect's for a single caret, we used to garbage the ; selRect. so, we now test ExpandMemRec.emTwoCursorsFlag in this ; case to avoid it. (bug #1007065) <34l-YDS-9/2/91> ; <34k> Fix TEGetPoint for styled TE for R->L scripts, used to asume ; that if we are on a begining of a style run, the width is 0, and ; if we are on the end, we should TextWidth all of it, which is ; not true for R->L scripts. (bug #1007067) <34k-YDS-9/2/91> ; <34j> Added support for a single caret while handling an Arrow (left ; or right) key, for styled L->R text. have to change the Keyboard ; in a different way to support the corect display of a single ; caret. <34j-YDS-9/2/91> ; <34i> Fix DoMeasure for Right to left text in unstyled TE, in order to ; support fix for unstyled, use _Pixel2Char instead of ; MeasureIt. <34i-YDS-9/2/91> ; <34h> Fix TEGetPoint Bug for Right to left text, use DoMeasure ; instead of MeasureIt. <34h-YDS-9/2/91> ; <34g> Synch Keyboard to click even with an unstyled TE record, ; this is not only a nice thing to do, but very importent when ; handling a single cursor on a bi-direction script, if we ; would like your single-split carret to be displayed ; correctly. <34g-YDS-9/2/91> ; <34f> when click on script boundry, take care of the next cursor ; update, has to do with the split carret stuff. This was fixed ; in SetKeyboard2Font and ClickKeyboard2Font.<34f-YDS-9/2/91> ; <34e> find where the click was (to define the right script).<34e-YDS-9/2/91> ; <34d> Support for a single carret, this supports the styled ; TE part.<34d-YDS-9/2/91> ; <34c> Added support for a single carret, it will expand & shrink ; the the right part of a cursor to show only "one" cursor, ; depending on the language, so we will gwt a moving cursor ; (when switching scripts). this supports the unstyled TE part.<34c-YDS-9/2/91> ; <34b> using the byte after the TwoByteCharBuffer in teDispatchH for ; fixes <3.3> and <3.4> (lastScript), so change the place it clears ; so only a word will cleared there.<34b-YDS-9/2/91> ; <34a> Fixing Hebrew/Arabic AppleLink bug that causes a big cursor: ; the right way! this fix is in alot of places. <34a-YDS-9/2/91> ; ; ; ; <33> 4/3/91 SMB jdr,#86089: (also, pke) Fixing appl-crashing bug in ; NewRomanFindLine - should be clearing the high word of d0 before ; doing a long operation. Shows up when applications use ; TEHitTestHook and have multiple styles on a line. ; <32> 2/14/91 SMB pke,#70628: Unfortunately, forced to remove support for Forward ; Delete that was added in <19>. Conditionalizing it out so it can ; be added again later. See <32>. ; <31> 2/14/91 SMB pke,#82817: After Dark and Chooser string clipping bug - ; NewRomanFindLine's dependency on _NPixel2Char takes into account ; the caret width when determining linebreaks. This 1 pixel ; difference caused strings that were 1 pixel too long to no ; longer completely display since the linebreak occured in a ; different place. The problem was that the measurement occured on ; the character boundary (after the final character of the string) ; and the leading edge value returned was F. TextEdit deals with ; these results by backing up one character to guarantee that all ; characters completely display when drawn. In the case of calling ; _NPixel2Char this is not necessary since it will still return ; the correct results and TextEdit will behave correctly based on ; these results. So, to fix this problem we no longer subtract one ; for the caret width before calling _(N)Pixel2Char. ; <30> 2/14/91 SMB pke,#68221: Completing the fix in TextBox to turn off ; PreseveGlyph before drawing in order to draw squished characters ; when their ascent or descent is larger than the font's metrics. ; This problem in TextBox can be demonstrated when an accented ; character appears in a dialog. The previous fix in <22> had the ; comefrom patch on _DrawText instead of _MoveTo although the rest ; of the patch was based on the MoveTo call. So, the patch was ; never executed since the address never corresponded to a ; DrawText call! Brain damaged! ; <29> 2/14/91 SMB pke,#DTS FT: Quit trashing a4 across Hook calls! ; <28> 2/11/91 SMB pke,#SMB-2/9/91-1: TextEdit didn't always erase characters when ; deleting them. Another symptom of this same bug is that TextEdit ; didn't line break at a CR. The problem was that when TE looked ; ahead for blanks at the end of a line in NewRomanFindLine, it ; skipped over blanks, CRs and any other character whose value was ; <=$20. Now it checks each breaking character for a CR and once ; found, forces a line break there. ; <27> 2/11/91 SMB jdt,#TEBug.ReCaLines: KanjiTalk bug fix in ReCalLines - need to ; back up 2 bytes for correct redrawing of double-byte text. ; <26> 2/11/91 SMB pke,#OYDBB002: Fixed the MathCad (application) bug in ; NewRomanFindLines by ckecking for a dummy style run at the end ; of the StyleRun array whose startChar = endChar. ; <25> 2/11/91 SMB pke,#SMB-2/10/91-1: TextEdit should be using the low memory ; TEDoText hook rather than jumping directly to the DoText patch! ; <24> 2/2/91 PKE KIP: Fix 606 build by renaming leftSide references in P2CFrame ; to leadingEdge in code that is only used if SysVers < $700. ; <23> 2/1/91 SMB pke,#HIG-JS-048,#81519,#82169: In NewRomanFindLine: testing for ; a blank at a line break before calling TE's FindWord routine. ; Fixed problem with styles in balloons: was comparing a final ; result to the linestart in d6, but it was modified for styles, ; so needed to compare to actual value saved in lineStart(a6). ; Fixed performance problem: change in algorithm caused unstyled ; TE to call TextWidth on the entire document (pinned to each ; lineStart) when determining line breaks. Major slowdown! Are now ; calling _NPixel2Char instead of _TextWidth & _Pixel2Char in TE's ; Pixel2Char routine (TEHitTestHook). Should make TE FAST(er)! ; Renamed leftSide to leadingEdge in P2CFrame and added ; WidthRemaining member (see TextEditPriv.a). ; <22> 1/22/91 SMB (pke) Re-fixing bug #68221. The previous fix required calling ; OutlineMetrics for the whole font in order to get an ascent & ; height in TextEdit. This wasn't acceptable due to reformatting ; problems. So, the code to support OutlineMetrics has been ; removed and we are now turning off PreserveGlyph before drawing ; in order to draw squished characters when their ascent or ; descent is larger than the font's metrics. GetFontInfo will ; still be used to get ascent & height, as in the past, and we ; will be backwards compatible although not pretty. ; <21> 1/20/91 SMB (csd) Fix incorrect calling of FindWord and FindLine when ; patching in ReCalLines and NewRomanFindLine. Must use the ; low-memory vectors to access the patches. Added a line in ; ptchRecalLines that was accidentally dropped (thereby causing ; some linebreaking problemsÉ) ; <20> 1/18/91 SMB (pke) Fixed bug # 62963 - No longer preserving a3/a4 across ; DumpBuffer routine. Saving a3 caused a dangling ptr and it's not ; necessary to save a4. Also, added a call to DumpBuffer in ; TEDispose in case an app never calls TEIdle (which empties the ; buffer). Changed _NewHandle call in GetHandle to allocate the ; handle in the System heap in order to prevent orphaning the ; handle when an application quit without emptying the text ; buffer. ¥ Also fixed a linebreaking bug in Pixel2Char - wasn't ; calling DoubleByte with the correct offset (was using the offset ; for the line not the offset w/in the whole text buffer thus ; far.) ; <19> 1/14/91 SMB (jdt) ¥ Added ptchReCalLines for a KT bug: Only draw line in ; ReCalLines when wordRedraw is <1. ¥ Fixed bug # 35646 (fixed for ; SS-6.0.4 and 6.0.5 in ptch0) - up-arrow key doesn't get to ; beginning of text. Had to add patches to PtToLine, DoFind, ; PinDisplay, PinA0Rect and the routines that called them: ; Refresh, Scroll, TEScroll, TEPinScroll. TEClick, TEKey, ; TEGetOffset, DefClikProc, DoDraw and DoHilite had to be updated ; to call these patched routines rather than the ROM routines. ¥ ; Fixed bug #66732 & #57858: if the scrap handle parameter ; (newStyles) in SetStylScrap was NIL should do nothing and exit. ; (see ptchTEDispatch) ¥ Fixed bug #58512: Must lock null scrap ; handle in InsRsrved before calling PstStylGuts since PstStylGuts ; expects to use the handle again after moving memory. Since ; InsGuts calls InsRsrved, patched InsGuts and the two routines ; that call it, TEInsert & TEStylInsert. ¥ Fixed bug #77962: TE ; was determining line breaks by measuring words rather than style ; runs for a Roman-only system. This was causing drawing to be ; significantly different than the measuring when FractEnable was ; on or a scaled font was used. Rewrote code (now called ; NewRomanFindLine) to do the right thing! ¥ fjs fixed bug #70628: ; adding forwardDeleteChar support in TEKey so that this function ; key on the extended keyboard works. ¥ Fixed bug #67699: ; StdTxMeas did not detect overflow when measuring long lines, so ; the widths returned to TE in this case were small, causing TE to ; write all the text on one line. StdTxMeas was modified to keep ; the last count and width before the overflow. This info is used ; to call _Pixel2Char to get the correct character offset for line ; breaking. ¥ Fixed bug #66900: TextBox did not clip text ; correctly for long words due to the incorrect use of _P2C's ; LeadingEdge flag. See changes in TE's Pixel2Char and ; ptchDoSearch. ¥ Fixed bug #68221: did not calculate the ascent & ; descent of an outline font correctly if preserveGlyph is true. ; Now calling OutlineMetrics for this. See routine ; GetOutlineMetrics; the routines needing it (TextBox & GetSize) ; require a comeFrom tail patch on GetFontInfo. ¥ Fixed Finder ; bugs #80728 & 75607: in StdEntry, for unstyled text, save the ; grafport's font info before setting the TERec's style info into ; the grafport. ; <18> 12/15/90 SMB (gbm) Added support for another gestalt selector, gestaltTE5, ; for the new TextWidthHook. ; <17> 10/30/90 SMB (PKE) ¥ Fix text buffering bug: must preserve register a1 ; (ExpandMem ptr) around a call to SetFont2Keyboard. Also, moved ; code that dumps the buffer in SetFont2Keyboard after determining ; that synchronizing was necessary. Then, must test for an empty ; buffer in TEBufferText after the SetFont2Keyboard call and after ; a full buffer has been dumped. Using hasBufferingFix conditional ; for these changes. ¥ Added TextWidthHook to dispatch table and ; the internal interface which uses the hook, TETextWidthHook to ; hook out the TextWidth calls to keep our developers happi(er)!. ; Renamed nTEWidthHook to ScriptChar2Pixel. Using hasTextWidthHook ; conditional for these changes. ; <16> 9/16/90 SMB Put GestaltTEciVersion proc and installation code back in. ; <15> 9/11/90 SMB Fix teCROnly bug that crashes the system: pre-incrementing ; caused us to compare one too many in the text and then the +1 to ; point beyond the CR caused the line breaks to be one off. Moved ; InlineInput test into TESetSelect instead of ClickKeyboard, ; since never want to call KeyScript while doing inline. If in ; Inline, then not hilighting to the EOLs anymore, only to edge of ; text (see InvrtRectangle). Modified highlighting code to ; highlight the middle rectangle line by line in order to call ; highHook for Inline. Fixed Hebrew/Arabic scrolling down bug - ; caused selRect's top & bottom values to be negative which caused ; a BIG caret to be drawn. Fixed in CaretInsideRun (revisited: ; must also bra if equal). ; <14> 8/14/90 DTY Changed into a linked patch. ; <13> 6/22/90 SMB NEEDED for SS-6.0.5, SIXPACK & 7.0: fixed Arabic line end bug ; for unstyled text, where the system slowed down because was ; reading off the end of the line starts. ; <12> 6/11/90 SMB NEEDED FOR SIXPACK & 7.0: Added Inline Input bit to ; TEFeatureFlag and support for it in ClickKeyboard2Font. ; <11> 5/29/90 DDG NEEDED FOR SIXPACK: Changed all the sixpack conditionals from ; six-point-oh-seven to six-point-oh-six. ; <9> 4/27/90 SMB NEEDED for SIXPACK - Fixed old bug for old FindWord: when using an ; application's teWordBreak routine must save d1! ; <8> 4/10/90 SMB NEEDED for 6.0.x, 7.0 and SS-6.0.5: Adding Scrolling Down bug ; fix that I erroneously omitted on 1/16/90! (see comment <3> ; below) ; <7> 3/20/90 SMB NEEDED for 6.0.5 and SS-6.0.4 - Added call to SetKeyboard2Font ; in TEKey (rather than DelGuts, see 1/23/90) for Script Systems: ; whenever backspacing over a script boundary the keyscript wasn't ; updated. Bug #59422. - Fixed TEFindWord for line breaking on a ; Roman-only system to branch for 'bge' to #teFromFind instead of ; 'bgt'. (Should have been in 1/23/90??) - In TEBufferText, must ; set d0 to the current position before calling SetFont2Keyboard ; (in case of a kbd change while buffering) ; <6> 2/18/90 SMB NEEDED for 6.0.5 - DoSearch didn't work correctly when the ; TEHitTestHook had been replaced. We needed to check a ; terminating condition when hooked out: the high word of d0 was ; set T if found a char offset. ; <5> 2/13/90 SMB NEEDED for 6.0.5 - Moved conditional test in ptchDelGuts. - ; Patched TEWidthHook in GetLRPosition, PixelWidths, and GetWidth. ; Also added nTEWidthHook and OldChar2Pixel. ; - Patched TEWidthHook in GetLRPosition, PixelWidths, and GetWidth. Also ; added nTEWidthHook and OldChar2Pixel. ; <4> 1/30/90 SMB NEEDED FOR SS-6.0.4 and 6.0.5 - ; 1/30/90 smb - Fix in TEKey so that when the current position is at a line end and ; the height of the current line is > the height of the next line, the ; down arrow will put the caret on the next line. Bug #53697. ; 1/30/90 smb -Decided NOT to fix bug 35646 for the IIci - up-arrow key doesn't get ; to beginning of text - since it wasn't very important and it would ; take a lot of patches in many routines to fix it. ; 1/29/90 smb - No longer call SetFont2Keyboard for ptchDumpBuffer. ; - Added patch to DoCaret to pin the caret in view when ; blanks exceed the edge of the view rect. ; 1/26/90 smb - Before synchronizing the font to the keybd, dump the text buffer: user ; could change the keyboard in the middle of buffering. (see TEBufferText and ; SetFont2Keyboard) ; 1/25/90 smb - Call HideCaret for up & down arrows to erase the old caret before ; setting teLftCaret in TEKey. Fixes bug #52887! ; - Fixed up arrow bug, #51967, that caused the caret to move up multiple ; lines according to the size of the largest font on the current line. ; - If zero width in DoSearch, want to branch ow this one pixel difference ; causes the caret to display on the wrong line ending. Roman fix. ; Bugs #58921,59247. ; 1/24/90 smb - Found bug in DoSearch where needed to setup a2 as current line again. ; 1/23/90 - Removed all equates and records since moved them into TextEditPriv.a. ; emt - Added humane scrolling (slower) to DefClikProc (also see TEClick). ; 1/23/90 - Changed FindWord branch for linebreaking to 'bge' instead of 'bgt'. ; - Added call to SetKeyboard2Font in DelGuts for Script Systems: ; whenever backspacing over a script boundary the keyscript wasn't ; updated. Bug #59422. ; - Reorg beginning of FindWord in order to be compatible with applications ; using incorrect char breaking algorithms for Script Systems. ; <3> 1/16/90 SMB NEEDED FOR 6.0.5 - Fixed bug in TEGetPoint, added double-byte ; buffer at end of dispatch record, fixed bug in r-to-l processing ; of caret that showed up when scrolling down. ; 1/8/90 SMB NEEDED FOR 6.0.4SS & 6.0.5: bug 58823, TEGetPoint returned ; incorrect values when there's no text in the TERec. ¥ Using ; private space in TEDispatchRec for buffering of a double-byte ; char rather than using ExpandMem as a global buffer which can ; affect any active TE record. This fixes a bug seen in KanjiTalk ; (AppleShare)when an application uses two TE records. Buffering ; in one record can be dumped into the other record due to the ; global storage space not knowing which record it applies to. ; <2> 1/4/90 PKE NEEDED FOR 6.0.5 (smb's changes from SS-6.0.4b23 to SS-6.0.4f1): ; ¥ Set the offset parameter to non-zero for StyledLineBreak for ; unstyled text. ¥ In ptchTESetStyle and ptchTEGetPoint must pop ; TEDispatch's return address. ¥ Added ptchHiliteMiddle and ; patched out more of OnSameLine and MeasureWidth to use this ; patched HiliteMiddle. Have to save d2! ALSO: Changed ; conditionals from (Scripts604 | SysVers >= $700) to (Scripts604 ; | SysVers >= $605). Updated header to BBS format. ; <1> 12/18/89 CCH Adding for the first time into BBS. ; BBS versions from here up: ;___________________________________________________________________________________________________ ; EASE versions below: ; <1.3> 12/14/89 smb Added ROMEndDoSearch jmp address since I left it off and broke ; the 6.0.5 build! ; <1.2> 12/11/89 smb More Arabic fixes: horizontal cursor movement now works at line ; ends. ; ¥ In CursorMovement and GetStyleEnd had to pin the style run to ; the line end for correct position. ; ¥ Need to use the high caret rectangle in TEKey rather than always ; using the teSelRect! ; ¥ Added a new keyboard/font synchronization routine to be used ; when doing a hit-down which allows a Roman keyboard with a ; non-Roman font, specifically because KanjiTalk wants to enter ; Roman text from a Japanese font. ; ¥ Fixed potential bug in TESetStyle: must test the doFont bit in ; the mode since it's possible for the mode to be an additive ; combination of styles. ; ¥ Use application font for SetFont2Keyboard rather than system ; font. ; ¥ Have to use emBufferPtr for a flag to indicate when I ; unsynchronize the font & keyboard in ClickKeyboard2Font. These ; will be used to keep SetFont2Keyboard from synchronizing the ; font & keyboard when trying to paste a character in this ; unsynchronized situation. ; ¥ Also had to add a call to ClickKeyboard2Font from TESetSelect ; in order for horizontal cursor movement to work correctly in ; this new unsynchronized situation. ; ¥ Fixed LR highlighting bug at line ends; in InvrtRectangle. ; ¥ Unconditionalized code in VisibleLength to fix a LR line w/ ; R justification display bug. Mark was right! ; ¥ Set flags in caret display code to indicate when in the middle ; of a style run but on a line end (see CaretInsideRun). ; ¥ Fixed bug in {hit-down on,cursor movement to} a script boundary ; to set the keyboard to the preceeding style run rather than the ; succeeding one. (see calls to ClickKeyboard2Font). ; ¥ In BufferChar & DumpBuffer backed up one offset posn to get ; previous style run for SetFont2Keybaord call. ; ¥ Fixed problem with setting the boundaries in ChkBounds. Also set ; boundary in DoDraw based on WordRedraw rather than teSysJust. ; ¥ Corrected test of teForceLeft in iTEGetPoint. ; ¥ Fixed bug of a large cursor (#52888) due to RomanFindLine (really ; StylMeasure & P2C) incorrectly increasing the char count due to ; an invalid leftSide flag set in TE's P2C. This caused ReCalLines ; to read beyond the end of the line heights record. Fixed by ; setting a flag which said to ignore the leftSide flag if TextWidth ; did the measuring in P2C. ; <1.1> 11/21/89 smb Bug fix in FindWord for Chinese Script System: clear ; fwLeadingEdge flag! ; ¥ Added updating of outlined region in TEUpdate. ; ¥ Fixed TETrimMeasure to call VisibleLength at the appropriate times ; for unstyled text: LineRect uses the line direction and ; justification to determine when to call it. ; ¥ Adding call to GetStylesInOrder in order to call VisibleLength ; for a line's style runs. We need to traverse the style runs in ; display order but backwards! ; ¥ Fixed buffering bug in BufferChar & TEKey; must set emBufferLen ; non-zero when buffer the 1st byte of a 2-byte character. ; ¥ Moved secondStyleRun and firstStyleRun from SharedFrame to ; FmtOrderFrame since TextFrame needs this info for XTrimMeasure ; changes. ; ¥ Bug fix for buffering 2 byte text on Kanji! see DumpBuffer and ; TEBufferText. ; ¥ Removed testing of LRTextFlag since it's based on WordRedraw. ; Will tst WordRedraw instead! ; ¥ Not removing setting of LRTextFlag in GetFormatOrdering or ; teGetFormatOrder since it won't hurt. ; ¥ Had to clear (a2) in iTEFeatureFlag so that the return result was ; set right for an initial state of clear (vs. set). ; ¥ Fixed ptchTrimMeasure for unstyled TE. Also added test for ; unstyled TE in ptchGetNextDisplayStyle. Moved firstStyleRun and ; secondStyleRun to "top" of FmtOrderFrame. ; ¥ In ptchTEGetPoint changed longs back to words as they were ; originally! ; ¥ Bug in DumpBuffer for unstyled textEdit: screwed up stack since was ; popping the stack w/o doing the push! Now doing the push as well! ; ¥ SecondStyleRun and firstStyleRun need to be above directionParam in ; the FmtOrderFrame! ; ¥ Added @getStyleNew code for right-to-left directional scripts in ; ptchDoSearch. ; ¥ Added a test in ptchGetRLPosition because when processing a CR ; entered at the EOD, the current line (a2) is the next line. This ; causes TE to look beyond the end of the lineStarts array. ; <1.0> 10/12/89 smb New file containing the TextEdit patches from PatchIIciROM.a. Is ; included therein. ;____________________________________________________________________________ ; To aid the historians, here is the recent history of TextEdit from PatchIIciROM.a: ; ; <7.7> 10/12/89 smb Moved TextEdit patches to TextEditPatchIIciROM.a. Fixed bug in ; old highlighting code that I introduced accidently (changed ; move.w -> move.l). ; <7.2> 10/5/89 smb Added old highlighting code for TextEdit for HyperCard ; outlining. ; <7.0> 10/4/89 smb Fixed 6.0.4 build by moving around some of my conditionals due ; to dependencies! Fixed TEInit to set TEDoText like it used to. ; Cleaned up TEOutlineHilite.
