Variables are actually created + with the translations 'declare' and 'get-values'. Example: + get-values(1, $x, x) + declare(1, $armed, true) + +resource-name: + Any resource name of the widget. Note that it requires a <TYPE> to + string converter in the code (I added some on the patches), since + all variables values are stored in a 'String' format. Example: + borderWidth + height + font + background + +constant-name: + Especial values. They aren't normally contants, but a special state + not triggered with resources or variables (They have the highest + precedence, so, to allow these strings as resource names I'll need + to allow some sort of escape sequences). Examples: + mine # event->xany.window == XtWindow(widget) + faked # event->xany.send_event != 0 + true # you know + false # " " + +args: + Special strings values interpreted by the translation binding. + +The operators (currently) understood are: + ~ - NOT + & - AND + | - OR + ^ - XOR + ( - RP + ) - LP + The final result value is and'ed with 1. + +Sample translation to make a label widget behave like a button: +<Map>:\ + get-values(1, $fg, foreground, $bg, background)\n\ +<Btn1Down>:\ + set-values(1, foreground, yellow, background, gray30)\n\ +<Btn1Up>:\ + set-values(1, foreground, $fg, background, $bg)\n + + + Description of the displayList system: +-------------------------------------------------------------------- + The display list has the syntax: + +[class-name:]function-name args[{;|\n}]... + + Where: +class-name: + Any registered set of functions. The code registers the class 'xlib', + and if the class name is not specified, this class is assumed. + +function-name: + A string binding to the correct function to be called. + +args: + A set of converted and shareable arguments, to the function. The + positioning/sizing arguments currently implemented have the syntax: +{+-}<integer> or <integer>/<integer>. Examples: + +0,+0 top, left + -0,-0 bottom, right + -+10,-+10 bottom+10, right+10 + +0,1/2 left, vcenter + + All displayLists are shared by: + widget->core.screen + widget->core.colormap + widget->core.depth + I have added only partial code for handling non-windowed widgets (gadgets). +I'll fix it. + + Example for drawing two lines crossing the widget: +foreground black;\ +line +0,+0,-0,-0;\ +line +0,-0,-0,+0 + + + +Patch 2 (#1660) 19 April 1998 + + + More functions for displayList's + + Fixes for simpleMenuWidget, xfontsel should work very better now. Try + this with the newer patches to verify the changes: + xfontsel -xrm '*XFontSel*SimpleMenu*font: +-*-helvetica-medium-r-*-*-16-*-*-*-*-*-*-1' + + Small bug fix to boxWidget, viewres should work better now. Try this + to verify the changes: + viewres -xrm '*Viewres*Box.borderWidth: 1' + + Small bug fix to panedWidget, when pressing in a gripWidget but not + moving the pointer, or releasing at the same coordinates. + +Patch 3 (#1673) 25 April 1998 + + + Changes in layout code for the Form widget. To see the changes, run xcalc + and resize it several times (try giving it a very small size and the + restore the size). The new code uses a 'known' reference size/position + to avoid integer rounding problems. + + A optimization for the Form widget. Now it unmaps itself before resizing + the child widgets. This way the layout process is very faster. + + The List widget will try to fit in a 32767x32767 window size. It checks + if the width or height will become bigger than 32767 and if will, changes + the number of columns. This fixes xman (at least for me, that have several + entries in the section 3 of the manpages). + + New functions to displayList's and fixes to some bad bugs (I'm yet working + on that file). + + Change in the Scrollbar functionality. It was redrawing the thumb when + triggering the MoveThumb action. This is bad because several programs + choose to recalculate the thumb position with XawScrollbarSetThumb, causing + screen flickering. Now it redraws the thumb when triggering the NotifyThumb + action. To verify the changes, run xfm or xman and try to scroll past the + end of a window; it will keep erasing and redrawing the thumb. + + Other change in the Scrollbar is that it will only draw in the rectangle: + 1, 1, core.width - 1, core.height - 1. It is better when creatting a 3d + effect with displayList's. + + +Patch 4 (#1678) 3 May 1998 + +Included the patches for the recent problems with libXaw. +Several 'gratuitous' small changes, to compile cleanly with gcc -Wall. +Some bug fixes for DisplayList.c. +Colored pixmaps support. I'm building a abstraction layer for the colored + pixmaps, so that it should be easy to support more pixmap formats + (actually, only X bitmaps). + + +Patch 5 (#1686) 11 May 1998 + + + Patch to libXmu, so that the StringToCursor converter will understand the + string 'None', that means not to use a cursor. This is useful when + overriding resource settings, and the user wants to use the parent window + cursor, or the root window cursor. Any unrecognized name will generate + a 'None' cursor, but then with a warning message. + + SimpleWidget was modified to allow setting the cursor to none, when it + was a valid cursor. + + Modification in the Actions.c, + from: + typedef struct _XawActionVar { + XrmQuark qname; + String value; + } XawActionVar; + to: + typedef struct _XawActionVar { + XrmQuark qname; + XrmQuark qvalue; + } XawActionVar; + This does not cause any problems, since the exported interface remains + the same. This is required to avoid to much copies of the same string. + + Values of action variables can start with '$'. + + If a resource name clashes with a special constant name when evaluating + a boolean expression (in the translations code), it's enough + start the resource name with '\\' (it can always be used, but is + only useful if there is a name clash :). + + The only code that loads data files actually is the pixmap code. To avoid + security problems, the code only loads files that are group readable, + regular file, non suid and non sgid. + + If the code to load a pixmap does not find a match, and the pixmap name + has a extension, try without the extension. + + Function 'line-with' added to displayList code. + + Added DisplayListToString and PixmapToString converters. + + Bug fixes in the pixmap name interpretation. + + +Patch 6 (#1701) 24 May 1998 + + Xaw + ------ + + Allows setting the resources label_x and label_y inherited from labelWidget. + This is useful for moving the contents of a button when it is pressed + ( I included a simple test for it ) + + Added OS/2 patchs + + The buffer overflow problems were resolved in a different way. I added + a function XmuSnprintf, that is used by Xaw and Xmu. + + Correction of a problem in SimpleMenu, when it tries to optimize the + space used by the menu. + + Xmu + ----- + + Function XmuNCopyISOLatin1Lowered, defined in <X11/Xmu/CharSet.h> + + Function XmuSnprintf, defined in <X11/Xmu/SysUtil.h> + + All ocurrences of sprintf were replaced by XmuSnprintf and all ocurrences + of XmuCopyISOLatin1Lowered were replaced by XmuNCopyISOLation1Lowered. + + +Patch 7 (#1738) 21 June 1998 + + + Corrected problem with the Command widget, when it was made insensitive + without calling the 'reset' action. + + Rework of the SimpleMenu code for optimizing the space used. Now it + really works as intended. + + Fixed portability problems with my previous patches. + + Corrected problem pointed by 'grano@cs.Helsinki.FI'. He have followed up + a bug report to the devel mailing list. While the problem exist, his + patch was not complete, so I did a rework of the AsciiSrc.c:Scan() and + MultiSrc.c:Scan() functions. + + I added clipping code to the {Ascii,Multi}Sink widgets, to allow use of + displayList's as decoration. The best solution I found to avoid too much + server requests, and keep full binary compatability was to use the resize + method of these widgets, to tell them to the parent widget have changed + it's size. + + Now the TextWidget has a xterm/emacs like cursor. And it is possible to + especify a cursor color. + + Fixed several problems caused by code assuming a line of text will be + shown as one line in the TextWidget. This is not always true when + it uses XawtextWrapLine or XawTextWrapWord, the most common problem was + the cursor becomming invisible, after calling the function + Text.c:_XawTextShowPosition() that is called to make sure it is visible ;) + + Added code that it will not forget the cursor distance from the left of + the window while moving the cursor one line up or down. + + Ansification of the text code (not yet complete). Private routines now + uses prototypes and wide parameters. External routines were kept + as before (but with prototypes not masked by NeedFunctionPrototypes), + to avoid binary compatability problems. The bigger problem I found in the + ansification was a function with 6 parameters being called with only 5. + + Several routines were rewritten, sometimes from scratch. + + The cursor navigation of the TextWidget was completely reviewed. It + should be very familiar to Emacs users. The most Emacs like behaviour is + when the cursor in move one line up or down and becomes invisible; the + text will be scrolled so that the line with the cursor will be centered + in the screen. Also, when doing page up, the cursor will be positioned + in the bottom-left, instead of allways in the top-left. + +Patch 8 (#1752) 27 June 1998 + + + There was a problem with the previous patch regarding to portability. + The problem was strcasecmp. I was planning to provide the funcionality + in libXmu, and forgot when creating the previous patch :(. There is + already a strcasecmp equivalent in libXmu, that is + Lower.c:XmuCompareISOLatin1(), so I used that function. + + The previous patch was working correctly for viewing text, but there were + some cases the text window could end not displaying correctly the text. + This problem was fixed. + + Now, the only real need of scrollbars is when doing long jumps on the + text, because the cursor will be always visible since this new patch + does horizontal scrolling automatically. + + +Patch 9 (#1755) 28 June 1998 + + + Removed all my RCS idents in the files. + + Declared functions as static in the prototype and in the definition + (this basically reverts a previous patch, but should help when applying + the patches sequentially). + + Changed the code in Pixmap.c to use strtok instead of strsep, that is + not portable. + + Corrected problem with previous patch that would cause trouble when + a text widget had more than 32K bytes, and would also cause offset + mismatches if a program access private structures (AsciiSinkP.h). + + +#1776 6 July 1998 + +Corrected problem when moving the cursor over a non-printing character, + i.e. ^Q ^X +Does not allow anymore scrolling of the text width Ctrl+Z if the text has + only one line, or only one line of text. +Several changes in the TextWidget. I did not gratuitously break binary + compatability. Source compatability is only granted to programs that + do not access private structures. This is required because there are + several changes in the behaviour of the TextWidget, and if a program + becomes non compilable, it is because it will not work properly with + the changes in the text widget (please read bellow for a explanation) +Better cursor navigation when moving line-up or line-down over a tab: + cursor + | + v + spaces | |#| | | |text + tab | |text + Move one line down: + before: + tab |# |text + now: + tab | |#ext +There were several problems in the Text.c:_XawTextReplace(), when deleting + a character and the cursor (shoud be) moved to the previous line. This + problem was corrected. +The text code was doing too much redrawing! When typping text, it would + redraw all the current line at each character typped, and also redraw the + entire window till the bottom. Now it only redraws the minimum necessary + (and makes a minimum of requests for the Xserver, when clearing areas), + most of these problems were related to Text.c:_XawTextReplace() (rewritten + from scratch), Text.c:_BuildLineTable() (mostly rewritten) and + Text.c:DisplayText() (mostly rewritten). +Now, when selecting text, with: button1-down, button1-move, the window will + be scrolled automatically, if the mouse is moved to the top or bottom of + the text window, making it easier to extend selections. +Added a set-keyboard-focus translation to the text code, and in the + default translation, it is called when pressing the left mouse button over + a text widget (so that the mouse does not need to be over the text window + when typping) + +These are the changes to Xaw that made it not fully source compatable (I'm +open to comments, to make it source compatable, but as I said above, if +a program does not compile anymore, it is because it is not granted it will +work properly): +scrollMode set to WhenNeeded is not supported anymore. I spent several + hours fighting side-effects caused when a scrollbar is created or destroyed + 'on demand', and have (after tired of long debug sessions) choosed that + it is not required (it saves a lot of potencial unespected conditions + being found by a user). I changed the 'type' of the scroll mode to Boolean, + so, to have a scrollbar, is enough to say: *Text.scrollVertical: True. + Since the type now is Boolean, Xt will print warning messages when the + scroll is set to 'Always', 'Never' or 'WhenNeeded' +automatic resize is nonsense since the text does automatic horizontal + scrolling. IMHO, to be useful, automatic resize should also shrink the + text window when needed, anyway, it's not required anymore + +Comments: +auto-fill mode does not work properly (never did) +wrap-mode set to line may not work properly +wrap-mode set to word does not work properly always (never did) +the multiply should be setable to a variable value; the default value + is 4, i.e. Ctrl+U <text+action> +I will work on the itens listed above, and I'm also planning: +one level undo, for text actions +C style indentation and 'jumping' the cursor to show matching '(', '[' + and '{' +other things that I don't remember now :) + + +-- XMU -- +Moved the code clipping code I have put in Text.c in my previous patch to + Xmu/Clip.c. There was a bug in the code I have put in Text.c (this is what + I get by cutting and pasting code under a #if 0 :(), but it was corrected. + The code in the new file 'Clip.c' is very useful for creating clipiing lists + and thus, avoiding too much server requests, or code for the same + functionality (poorly) repeteated in several places around the libary. This + code is now heavily used by the TextWidget. + + +-- XEDIT -- +Removed a XDefineCursor in xedit.c:main(). There are several ways to specify + a cursor for a program (most times inherited from the wm decoration window), + so, it is better to let the user choose one. +Before starting the main loop, now xedit sets the keyboard focus to the + text window if a file was loaded, or to the prompt for a file name if + none was especified in the command line (do not use the new xedit without + the new Xaw library, or you will not be able to change the keyboard focus). +Updated the Scrollbar configurations in Xedit.ad + + +#1788 12 July 1998 + +-- TextWidget -- + + Corrected problem whem moving the cursor over a non-printing character + + Now, does not allow scroll with ^Z when there is only one line of text + + Automatic resize was removed, it is not required with automatic horizontal + scroll, but I will look for programs that rely on it; the only program + affected (that I know) is xmh, because it popups dialogs of a small size, + and expects that the text widget (with a warning message) do a geometry + request. + + Scroll mode set to "WhenNeeded" was removed. It generates several unespected + conditions when editing text, and the new feature of automatic scrolling + the text widget while typping is more useful. + + Removed a leak in TextAction.c:AutoFill(), generated by the code + text.ptr = (char *)XtMalloc(sizeof(wchar_t) * 2); + that memory was never released, but the fix was simple, since the amount + of memory requested is fixed. + + Several optimizations in the redisplay of the text. + + Now, wrap mode set to word or line is expected to work, while typping text. + + AutoFill will only break lines in word boundaries now. + + Added a set-keyboard-focus action to TextAction.c, so that when pressing + the left button over a text widget, it will receive the keyboard focus. + This behaviour is the default, but can be disabled, with something like: + *Text.translations: #override\n<Btn1Down>: select-start()\n + in your .Xdefaults. + + Corrected several cases that would left the text widget showing incorrect + data. All the problems should have been fixed, but in case you find one, + a quick fix is: + *Text.backgroundPixmap: black?foreground=<some-color> + because it does not try to optimize the redrawing when using a background + pixmap, and thus, avoid several possible problems. + + +-- XAW -- + + I had added a XawStackAlloc definition to "Private.h", to avoid a XtMalloc + request for every character typped in TextAction.c:InsertChar(), but + when syncing with 3.9Aj, saw that the file "XawAlloc.h" is no longer + required. Please, remove XawAlloc.h from 3.9Aj. + + +-- XMU -- + + Added the file Clip.c, with clipping code, that, now is being used by + the text widget, but can be used by other widgets. + +-- xedit -- + + Removed a XDefineCursor from xedit.c:main() + + I have added a XtSetKeyboardFocus in xedit.c:main(), but comented it + because it would make xedit unusable with previous versions of Xaw, + or with the Xaw replacements (Xaw3d, Xaw95 ...) + +Comments: + I wrote a lot of code to work properly with italic fonts in the text widget, +that code made the cursor do not erase portions of the text while moving the +it, but it was failing at some places that would need that the TextWidget, +and not only the {Ascii,Multi}SinkObject had access to the fonts, so I +choosed to left it to the future (and keep the sources simple, by now). +The text widget is useable with italic fonts, but fonts with: + f->per_char[<char> - f->min_char_or_byte2].rbearing + > f->per_char[<char> - f->min_char_or_byte2].width +or + f->per_char[<char> - f->min_char_or_byte2].lbearing < 0 +will not allways be displayed correctly. + + I haved also added a xedit configuration file to this mail. + + +#1842 27 July 1998 + +Fixed problem with the default macro for type conversion, where it was + possible to the code tell the wrong size of a string, since it was + returning the string size with 'strlen' but making the copy with strcpy. +Complete ansification of Xaw (and Xmu). +Corrected some problems caused due to an alteration in the text code, to + make the cursor always visible when the wrap mode is 'line' or 'word'. +Text.c:VJump() was made a bit smarter and a problem that would cause it + to jump incorrectly was also corrected so that now the jumping should be + very smooth. +Corrected problem that would cause a coredump due to the + Text.c:_XawTextReplace() deferencing a NULL pointer. Now ctx->text.lt.info + is initialized when the text widget is created, solving this problem. +All the variables with name 'new' and 'class' where renamed to 'cnew' and + 'cclass'. This allows even building Xaw with 'gcc -x c++'. +Variables shadowing other variables or functions where also renamed. +Static functions were changed to use wide parameters, where applicable. +(Almost) every time a StringTo<Type> converter is installed in the class + initialization of a widget, the code also installs a <Type>ToString converter + since now editres seens to work better. +Complete reestilization of the indentation. See the files Template*.{c,h}. +Corrected problem with the 'virtual' function Layout of the Form widget. That + function requires 4 parameters, but the Viewport widget (a Form subclass) was + calling that function with only 3 parameters; the ansification flagred that + error. +TextTr.c was modified to have only one string. I believe that that weird + thing was due to the inheritance of compatability with some very old and + probably buggy ld. +Xaw is expected to be binary compatable with R6.3; there are some + preprocessor macros that keeps binary compatability, and unless the gains + of breaking binary compatability show worth enough (and people think) it + is good that code would be made default, otherwise it will be forgotten. +I have also added a XFree86 copyright notice to Text.c, since there is + a very large amount of work in that file (and it is not yet ready). +--------------------- + +-------- Xmu -------- +Complete ansification of Xmu. +Rework of EditresCom.c to allow editres working correctly. It was also + added a new feature, that allows editres finding some extra child widgets, + i.e. widgets that aren't a child of a subclass of composite and aren't in + the popup list. This modification is not enough, since it does not find + child widgets that don't a XtRWidget resource in the parent widget. +Rework of ShapeWidg.c, so that it will give the correct feeling to the + ellipse shape, and inversion of the oval, if shape is oval and + height > width. To see these changes, run a program with: + <prog> -xrm '*shapeStyle: ellipse' + and/or + <prog> -xrm '*shapeStyle: oval' +Revision of DrRndRect.c to make the widget looks 'more correct' when using: + <prog> -xrm '*shapeStyle: roundedRectangle' +--------------------- + +------ editres ------ +Added small patch to bug in handler.c so that editres will correctly now. +--------------------- + +------- xedit ------- +Changed the resources file, to avoid a problem when resizing xedit to a + very small size and than restoring it's size. Probably the culprit is the + Paned widget, but the new resource file is at least a good workaround for + the problem. +The resource file was also modified so that the default xedit size will + give a 80x25 rows/columns when using the default font. +--------------------- + +-------- xgc -------- +Small patch to clear correctly the status text window, when pressing the + 'Clear window' button. Note that this patch showed a bug in + Xaw/{Ascii,Multi}Src.c; only apply this patch with the latest Xaw, or + be sure that Xaw/{Ascii,Multi}Src.c:*SetValues() has something like: + if (old_src->ascii_src.ascii_length != src->ascii_src.ascii_length) + src->ascii_src.piece_size = src->ascii_src.ascii_length + 1; + instead of: + if (old_src->ascii_src.ascii_length != src->ascii_src.ascii_length) + src->ascii_src.piece_size = src->ascii_src.ascii_length; + or it will enter a infinite XtMalloc(0) loop :( +also fixed a possible buffer overflow while searching the source of the + bug described above. +--------------------- + +#1945, 31 Aug 1998 + +-- XAW -- + + Corrected bug in Viewport.c:ComputeLayout(), that would put the scrollbar + in the incorrect position, if w->viewport.useright == True + + Corrected bug in Converters.c:_XawCvtCARD32ToString(), so that now it + will correctly format the converted value. + + Corrected problem in {Ascii,Multi}Src.c:Search(), that would cause a + incorrect offset to be returned, if the searched text (or a substring of + it) were in a 'Piece' boundary. + + Some small patches to other sections of the code, to reduce the number + of warnings generated by gcc, when using more restrictive warning options. + +-- XMU -- + + Corrected a problem in Atoms.c:GetAtomName(), to return a NULL pointer, + instead of a const if the given atom is 0. + + Corrected a typo in Xmu.h + + Several 'ansification' patches, to get function definitions and avoid + unecessary definitions. + + +#2028, 2033, 7 Oct 1998 + +-- Xaw -- +Added a delete translation to the text widget, that deletes the current + selection if any, else the backwards char. +Corrected bug that would not update correctly the screen if page-up or + page-down was pressed while there was an selection. +Added a ^Q<any-char> translation to the text widget, to be able to insert + any char in the text. +Changed TextAction.c:Move() to set ctx->text.showposition, so that even + if the cursor did not change the position, it will become visible. +Corrected problem with the 'form-paragraph' translation, so that the + text will be always correclty shown. +Modified the automatic scrolling of the text to one line at a time, to + make it easier to see what is being selected. +Added a 'hack' to be able to type ^U<any-numeric-sequence> to be able + set the multiply of the text widget. Since it is a hack (besides seens + to work very well) it can be disabled with -DNO_NUMERIC_HACK +Corrected a nasty bug in Text.c:CvtStringToScrollMode(); XtConvertAndStore + can't be called from a type converter! +added UNDO/REDO to the text widget. Please try it, I think it is very nice. + Undo is enabled by the new resource 'enableUndo', and, by default is + triggered with 'Ctrl+_'. + +-- editres -- +Resubmitting a patch to editres/handler.c, to make editres work properly. + +-- xedit -- +NOTE that with this patch, xedit probably will not work with Xaw3d, neXtaw... + this surelly can be fixed, or in the xedit side or the *Xaw* side, but + the patch seens to be necessary. +Changed the defaults file to be more user friendly and previsible. + Added some 'Emacs like' binding translations. +Added file completion in the filename prompt. This is a very nice + feature, but I'm not sure if the code is portable to all the XFree86 + supported platforms (surely it will not work 'as is' with OS/2). + + +#2083 18 Oct 1998 + +-- XAW -- +Changed the functions {Ascii,Multi}Sink.c:CharWidth and PaintText, to + improve speed, and avoid too much recalculations. On normal files, it + becames about 5:1 faster, but can go up to 20:1 when editting files with + very large lines. Besides this speed improvement, I believe it can + surely be made faster (based on comparition with some popular X editors). +Changed the way the AsciiSink prints characters with value bigger than + 126 decimal. Now it prints DEL as ^?, and the other characters as \XXX + where 'X' is an octal digit. The MultiSink widget was unchanged in this + respect, i.e. when calling xedit with something like: + xedit -xrm '*international: true' +Converted all calls to strncpy, in AsciiSrc.c to memcpy, so that the (ascii) + text widget will work properly with data containing nulls. +Added a experimental 'Xaw Scan Type' XawstAlphaNumeric, that shoud make + edition of C (or any other language) easier in xedit (i.e. the text widget). + It can be tested with Ctrl-Left and Ctrl-Right, by now. +Changed the TextWidget to handle text lines that would result in more than + 32767 pixels. Besides the text widget is not meant to be used in the + edition of binary files, this change allows it. +Changed Text.c:TextScroll() to be smarter when calculating the offset of + the line table on scroll up. +Added a nice feature, to show the matching '(', '[' or '{', when a ')', + ']' or '}' is typped. +Changed TextAction.c:FormParagraph() to generate only one undo/redo step. + +-- xedit -- +Changed the defaults file to enable backups and made the backup suffix + the character '~'. +Replaced all instances of sprintf by XmuSnprintf. +Changed xedit to set the label when saving a file also, to reflect what + is being edited correctly. +Corrected a bug in the new action 'file-completion', to replace correctly + the home directory, and keep correctly whatever was after the '~'. This + isn't the correct place to this code (xedit/commands.c), since there are + several other file name prompt windows in Xaw, but since it is required + another window to show the possible matches, I'll study a better way to + implement it. +Added a 'hints' feature to xedit. Instead of a 'dead' + "Use Control-S and Control-R to Search." label, now it allows the label + string being changed at user settable intervals. + + +#2205 10 Nov 1998 + +-- xaw -- + + Fixed some 16 bit overflows in AsciiSink.c and some cases where it would draw + past the end of the text window (a no-op), the overflows were not a + problem, but could left the text window with incorrect data. + + Moved the undo/redo code to TextSrc.c, and some code/data from + {Ascii,Multi}Src.c to TextSrc.c. The callback now is called when the + source is changed, or becames unchanged due to an undo/redo. Also + changed the Scan procedure to be a bit faster. + + The asciiTextWidget will now accept a source or sink object being set at + creation time. + + Fixed the 'struct XawDisplayList' being redefined when compiling Xaw under + SunOS. + + Several changes to the SimpleMenuWidget to make the geometry management + work correctly when adding/removing/changing menu entries at run-time. + + Added a 'kill-ring' feature to the TextWidget. The behaviour is identical + to Emacs. Pressing C-K repeteadely will merge the lines being killed, so + that a C-Y latter will paste all the killed lines. + + Added the enough glue code (and as backwards compatible as possible) to + allow the *src object be shared between several TextWidgets. My initial idea + was to make the TextWidget be able to have more than one source, but, to + be backwards compatible, I did the reverse (the source can have more than + one TextWidget). + + Fixed a automatic wrap bug (TextWidget) that could eat non white space + characters (my previous patch to this problem was completely wrong). + +-- xedit -- + + Added a split-window feature to xedit. To keep xedit simple, it only allows + two windows at the same time: or subdivides in the vertical or horizontal. + + Added more some key-bindings, that should do the same as Emacs. + +#2291 5 Dec 1998 + +-- Xaw (only changes to the 'text' code) -- + + Changed the default 'piece size' from BUFSIZ to the value returned by + the getpagesize() function (or keep BUFSIZ if that value is smaller). + + Added a case sensitive option to the search popup. This is a 'hack' by + now, but should not cause trouble to anybody. + + Fixed a bug inserted when changing the code for the search, the only side + effect I saw was that the jumping cursor to show the matching '(', '[' or '{' + stopped working in my last patch. + + Moved back my change to the function XawTextSetSource. The 'correct' function + is _XawTextSetSource. This is only to make sure old code should compile + cleanly. + + Added line and column number calculation code (and a callback to tell when + that information changed) to the TextWidget. This was not an easy task, + because I tried to optimize as much as possible the code, and do relative + calculations, instead of scanning the entire file to count the number of + lines (there are several special cases, when removing/inserting text). + + Added the selection type XawselectAlphaNumeric. This adds one step in + the sequence word-line-all when doing multiclick in the text. + + Fixed some bugs in the 'kill ring' feature added in the last patch. Now + it is expected to never fail. + + Corrected the indentation of TextP.h, and changed more some fields. The + internal data of the TextWidget changed a lot, so it is not expected that + program code read directly the private data, at the price of requiring the + correct library version. + + Fixed a small bug in the undo code, that would 'think' the file was unchanged + in the incorrect position in the undo buffer. + + Changed the default key bindings for delete/kill word functions to use the + alpha numeric versions (this is better for coding, and more compatible with + other text editors). + +-- xedit -- + + Changed the labelWindow, to show the current line number (but it is also + possible to show the current column number, offset or file size). + + Fixed bug when saving the *scratch* buffer with a new name. + + The 'changedBitmap' is now correctly displayed on all the windows showing a + changed file. + + Small changes to the xedit man page. + + + +#2371 8 Jan 1999 + +--- Xaw --- + + More some changes to AsciiSrc.c:Scan(). This improves a bit the speed when + scanning text. + + Added sanity checking for AsciiSrc.c:Search(), to avoid the risk of + deferecing a null pointer (or reading memory out of the text piece) if the + searched text happens to be larger than a "piece size". + + Fixed bug when trying to optimize line number calculation, due to a typo, + while meaning XawTextWrapNever I wrote XawTextWrapLine. + + Fixed a problem shown by xclipboard, when setting the "string" resource + of the text source, the sink object was keeping the insertPosition in the + old text contents, and then, when showing the cursor, it was incorrectly + 'erasing' the old cursor position. + + Fixed problem in XawTextReplace, that would not update correctly all the + TextWidget's sharing the same source. + + Added a kill ring list to the text code. This works like the emacs feature, + but, unlike emacs, it is not required to press C-Y before M-Y, to start + looping through the kill ring list. To use it, just press M-Y repeteadly, + and all the text that was killed will be inserted, one at a time, so that + you can choose one. Note that the text inserted from the kill ring list + will also enter in the undo list. + + Changed the Move{Backward,Forward}Paragraph actions to make the cursor always + stop in a blank line. This makes only one step moving from a paragragh to + another, instead of two. + + Added code to check for overflows in the C-U<number> sequence. + + Changed the FormParagraph action to keep the cursor at the correct position. + + Changed the default translations in TextTr.c to get a more emacs like + behaviour with the kill ring list. + +--- xedit --- + + Added a few more resource settings to the Xedit-sample file. + + Added some sanity checkings when trying to save a file. This avoids the + case of saving a file with the name of a directory (but moving the directoy + to other name before). A possible case is: have a directory named 'dir', + saves a file as 'dir', but before saving, renames the directory as 'dir~'. + + Allows saving a file that xedit thinks is not changed (the file may have + changed on the disk, but the user really wants to rewrite it). + + Corrected several bugs in the FileCompletion action, and added a new + feature, that is to complete the partial names, when there is a '/' or '.' + after the cursor position. + + +#2479 19 Feb 1999 + +-- Xaw -- + + Fixed bug in the line numbering code, when removing lines before the + top position. + + Changed code to form regions to always show the cursor after formatting the + text. + +-- xedit -- + + Added code to keep the file mode, after saving. This is useful when editting + scripts, so that the executable flag will not be lost after edition. + + +#2544 12 Mar 1999 + +-- Xaw -- + Mostly changes to add support to latin-* languages in the text code, when not + using the international resource. +Actions.c: + + Corrected some bugs in the boolean expression parser. The old version would + not parse correclty parenthized expressions, and was giving equal precedence + to AND, OR and XOR (what is incorrect). +AsciiSink.c: + + Changed to display characters in the range 0x32-0x7e and 0xa0-0xff literally. + The other characters are represented as control-codes, as before. This is + better for edition of Latin-* text files. +AsciiText.c: + + Changed the code, so that even if the *international resource is not set, + _XawImRegister and _XawImUnregister are called for the text widget. This is + useful for latin-* locales, that use one byte wide characters, and makes Xaw + more compatable with modern toolkits, like qt and gtk. +List.c: + + Added code to work correctly with a background pixmap. + + Added a smarter code for list window size calculation, that is used if the + number of columns is especified to be zero (automatic). +MultiSink.c: + + Fixed a core-dump problem caused when passing a null pointer to + XwcTextEscapement. +Text.c: + + Removed the resource adjustScrollbars. This resource was not used, and its + funcionality was not finished, and by now, it is not required. +TextAction.c: + + Does not call XLookpupString in InsertChar any more, but the new function + _XawLookupString (in XawIm.c) to work correclty with composed characters. +XawIm.c: + + Added the private function _XawLookupString, that just calls XmbLookupString, + or in case of any initialization error, XLookupString. + +-- xedit -- + The most important change is the addition of a new functionality, that allows + the user to navigate the file system, in a 'ls -a' like list widget, if + the file is not a directory it is loaded for edition, else, the list widget + is rebuilt with the contents of the selected directory. To test it, just + type: C-X d, or tab when 'finding a file'. To exit the dirwindow without + loading a file, type C-G or Escape. +Xedit-sample: + + Added more some resource entries, to use the new 'emacs dired like' feature. +Xedit.ad: + + Same as for Xedit-sample, but more important resource settings. +commands.c: + + The code now checks if the filename is a directory and calls the dirwindow + code in that case, when trying to open a file. + + Changed the function IsDir from static to global, to use it from xedit.c. + + Most of the code for the filesystem navigation window was added to this file. +util.c: + + Fixed a bug that was causing core dump due to passing garbage to XtGetValues + as the widget address. + + Added the code for managing the dirwindow and its relationship with the + text windows to this file. +xedit.c: + + Added the code for creation the dirwindow to this file. + + +#2638 2 Apr 1999 +-- Xaw -- + + Added xpm pixmaps support to the library. This time, it is required to + compile Xaw with -DUSE_XPM. + + If the xpm image has a mask, the widget will be automatically reshaped + to the pixmap mask. + + Changed the kill_ring code in TextAction.c to always end in a text block + of zero length, this way, it is easier to know when one traversed the + entire kill ring (it may be interesting to forget the undo sequences + while traversing the kill ring list). + +-- xedit -- + + Changed the Xedit.ad file to avoid overriding a translation that would + make the search window do not respond to WM_DELETE_WINODW messages. + + Fixed a core dump condition in the new code for listing files and + directories, due to deferencing a null pointer. + + +#2662 10 Apr 1999 +-- Xaw -- + + Corrected the problems gererated in my last patch. I was compiling with + -DUSE_XPM defined, and did'nt realize that the patch would not compile + without it. Just ifdef'ed again the code to avoid warnings or dead code. + +-- xedit -- + + Added a ispell interface to xedit. Sorry for not documenting enough about it + the man page, but here is a small explanation of the new funcionality: + Replace: Replace's the selected word. + All (right side of Replace button): Replaces all occurrences of the selected + word. + Undo: When this button is sensitive, allow undoing the last replace, + this is useful when doing a incorrect "Replace All" action. + Ignore: Ignore this word, and continues spell checking. + All (right side of Ignore button): Ignore any further ocurrences of the + selected word. + Add: Add's the selected word to the user's private dictionary. + Suspend: Go back to text edition, but does not kill the ispell process, + This is useful if you have a really big dictionary or slow + machine. I believe it is mostly useful to keep in memory + the words selected to be ignored, but that you don't want to + add to your private dictionary. + Close: Kill the ispell process, and go back to text edition. + Automatically saves the user's private dictionary. + When pressing the Add button, the word in the "Mispelled word:" field is + added to the user private dictionary (normally ~/.ispell_*). When pressing + the Replace button, the text in the "Replace with:" field is used. + If no word is selected in the "Suggestions:" field, this mean that the + selected word was not found in the ispell dictionary. + + +#2716 24 Apr 1999 +-- Xaw -- + + Minor changes to AsciiSrc.c to try to get more speed in the FindPiece + function. Xedit may become very slow when editing files bigger than 1M, + and I'm studing ways to get more speed in the Scan and FindPiece functions. + The FindPosition function in *Sink.c also can consume a lot of cpu time, + and may need some rework. + + Added submenus support to the SimpleMenuWidget. This is something essencial + to a widget toolkit. Just plugged in the code of a menu widget I wrote some + time ago. Xedit uses submenus now. To use it, set the resource menuName + of a SmeBSBObject to the name of the submenu. + + Added code for text justification to the TextWidget. To use the justification, + set the resources autoFill, leftColumn and rightColumn. If autoFill is set, + and leftColumn is smaller than rightColumn, an alternate code will be + used in the form-paragrpah action, normally triggered with M-Q. The values + for justification can be left, right, center and full. + + Added a overwrite mode to the TextWidget. The default translation is to + press the Insert key, that will toggle the overwrite mode. + + Made the TextWidget understand negative values for the multiply. This is + like the emacs feature, to indent text to the left. To set a negative value + to the multiply, just start the numeric sequence with a '-'. Like C-U -1. + + The code for justification added several new functions to TextAction.c. + Functions to tabify, untabify, get block boundaries, verify if a line + is completely blank, and strip excess of spaces. + + Added a indent action to the TextWidget. The default translation, only + used by xedit, is C-X Tab, did this way, to make it fully compatable with + emacs, but other translations can be used. The multiply value is used to + calculate the amount of spaces to move to the left or right. + + Corrected a very hard to find (and reproduce) bug in the undo code, that + would easily cause core dumps. The problem would happen when starting + editing exactly in the moment the redo automatically reverts to undo. + + Added translations for toggling the overwriting mode with the Insert key, + and to paste the selection with S-Insert. + +-- xedit -- + + Corrected all the known bugs in the ispell code (including a memory leak). + And added a compile time limit of 16 levels of undo, for all the actions, + that include Add, Ignore and Replace. 16 levels is more than enough, but + more than this can be done with the undo action, but then, only to revert + replaced text, to remove added words that the undo code forgot, it is + required to edit the personal dictionary file. The code now also understands + root/affix combinations, that ispell normally returns when using the + -m option. The ispell code should now also work when using the international + resource of the edit window. + + Added a new file, called options.c, that holds the code for the editMenu, + to enabling setting the wrap, autoFill, justify, leftColumn, rightColumn, + verticalScroll and horizontalScroll resources of the current edit window. + + +#2746 1 May 1999 +-- Xaw -- + + Reverted most of the #if NeedWidePrototypes definitions, only two + functions were kept, to not break some of the new features, but these + functions aren't called by any program: XawTextSinkDisplayText and + XawTextSinkClearToBackground. + + Rewrite of the functions *Sink.c:FindPosition() and FindDistance() to + try to get more speed. + + Reworked the function Text.c:_BuildLineTable, to correct some strange + code, and to avoid unecessary recalculations. + + Made negative values of the multiply work for all the actions, not only + for negative indentations. This makes the TextWidget behaviour more + compatable with emacs. + + Optimization of the new code for text justification, to avoid a call to + malloc on every char typped, when undo is enabled. + + Reorganized the offsets of the fields of the TextWidget, trying to make + xxgdb work again with the new Xaw code, but, unfortunately, the SimpleWidget + (a subclass of the TextWidget) have growed by 4 bytes (a XawDisplayList*) + added at the end of the structure, and xxgdb incorrectly reads the text.sink + field. Old xxgdb binaries dont work with the current code. + + Removed several XtIsSubclass checks in TextSrc.c. While those checks could + be useful for debugging, the functions are called so frequently that it is + a big waste of time for running programs. + +-- xedit -- + + Added/Changed some translations to work correctly when CapsLock and/or NumLock + are pressed. + + Fixed some bugs in the ispell code. The biggest bug was that it was not + correctly saving the Add'ed words in the user dictionary when pressing the + Close button. + + +#2764 8 May 1999 +-- Xaw -- + + Create two new private functions, to replace internally the public interfaces. + These two functions are XawTextSinkClearToBackground and + XawTextSinkDisplayText. These two functions use wide prototypes, and + are required to support text lines that are represented by more than + 32767 pixels. This was done to make sure that the public interfaces remain + 100% backwards compatible. + + Fixed the deferencing of a null pointer when the source object of a text + widget is not initialized. I noticed this problem when recompiling xcolorsel. + + Added a new type converter to Converters.c, that is Short -> String. + + Added a new compile time option, called NO_BIN_COMPAT_HACK. If defined, + it will break some programs that access private data. It only works with + programs that access private data structures, but don't subclassify any + widget. It fixed old binaries of chimera1, the Offix editor and xxgdb. + There is no way to fix old binaries of chimera2, xcolorsel and xmh, these + programs need to be recompiled. I would like to know of other programs that + became broken, to try to fix them with the NO_BIN_COMPAT_HACK option. + + Fixed some compile warnings, with shadowed, uninitialized and unused + variables. + + Fixed a inifite loop problem that could happen when the text widget window + was resized to a very small width. + + Reverted some of the text widget translations, to avoid conflicts when + setting the input focus and programs that do so. + +-- xedit -- + + Fixed a problem in the file-completion code, that would insert the partial + match in the incorrect position, if the cursor was not at the end of the + string. + + Changed ispell.c to use only one hash for ignored and added words. Also + changed the IspellSend function to not call itself recursively, what is + a big problem when spell checking big files that are correct or have too + few errors. + +-- editres -- + + Changed Editres.ad in several places, to try to avoid resource setting + problems. Most of them were changed to address more directly the resource, + and avoid confusion. Also, added some new resource settings to configure + the code I added to widgets.c. + + Changed widgets.c to make sure the resource setting dialog is allways + entirely in the screen, and if it does not fit, scrollbars will be created. + + +#2793 15 May 1999 +-- Xaw -- + + Changed AsciiSrc.c:LoadPieces to load the file incrementally, instead of + allocating a big buffer. + + Added several new functions to DisplayList.c. Almost all gc and painting + related functions were mapped to displayList functions. There are + several optimizations that can yet be done to the displayList code, and + I'm working on it. That code is clearly not finished yet, but is stable. + Also, changed some functions to be more exigent with it's parameters, + because it is better to receive a warning message than see the program + core dumping. The functions are documented in Xaw.man. + + Corrected a problem in the SimpleMenu code, to make the sub menus popup + more 'visually' correct, when popping up in the left side. + + Added a optimization in Text.c, to avoid unnecessarily recalculating + the line and column number when scrolling text. A big speed up should + be seen when scrolling large files. + + Modified all code that expected TAB_SIZE to be equal to 8, to read the + TextSink resources, and work properly with whatever value the program + had set to the tab stops. + + Fixed a very bad bug in the form-paragraph function. It was very hard + to find because I was looking at the wrong places. If the text was + allready formatted, or did not need formatting, the code was not + reenabling undo, making the undo/redo behaviour imprevisible. + +-- xedit -- + + Added Xedit-color.ad file, to show some of the new features of Xaw. + Tried to keep it simple, but since it uses gradients, maybe it should + better be called Xedit-TrueColor. The better way to see the functionality + of this file is (if you don't have it already) add to your .Xdefaults: +#ifdef COLOR +*customization: -color +#endif + and make sure xrdb parses it. + + Changed a bit Xedit.ad, to work properly when Caps Lock is pressed. + + Several changes to ispell.c. It should run very faster now, because + the code keeps information about words already ignored or correct + in the xedit side, instead of asking ispell every time. Added also + a terseMode resource, and made the interface ask for user interaction + allways ispell does not say the word is completely correct; the + terseMode resource makes ispell itself decide what words are correct + or not. + +-- editres -- + + Small patch to Edit-col.ad, to use a default text cursor color of 'Azure' + in text fields, instead of the default 'black'. + + +#2811 22 May 1999 +-- Xaw -- + + Removed the 'NO_NUMERIC_HACK' preprocessor definition, and renamed the + 'doing_numeric_hack' field of the text widget to 'numeric'. + + Changed the code to always create the horizontal scrollbar, if requested. + + Small changes to TextPop.c, to automatically scroll horizontally the + text window when the text found in a search/replace action is not visible. + + Added a optimization when editting large files, to rebuild the line table + if the region containing the text being added/replaced overlaps the lt.top + field of the text widget. + + Changed the undo code to also merge text typed when overwrite mode is + active. The new behaviour is not like emacs (that generates a undo step + for every character), but uses less memory, making only one undo/redo step. + +-- xedit -- + + Added a new file, hook.c that is intended to be used for the addition of + some new features to xedit, like auto indentation of program files. The + first feature added is the 'autoReplace' resource, described in the xedit + man page. + + Corrected a bug in ispell.c, that would make the code alocate lots of + memory unnecessarily, due to an uninitialized variable. Thanks to David + Dawes that found the bug. The bug was not in 3.9Pn, but the solution in + the later release was not completely correct. + + +#2834 29 May 1999 +-- Xaw -- + + Added a ChangeSensitive function to Command.c, to avoid it creating an + incorrect insensitive border if the button is set. This is a side effect of + the function XawCommandToggle I added some time ago. The solution for the + problem is not very elegant, since it copies almost verbatim the code from + Simple.c, but it works as expected. + + Moved some calls to _XawTextSetLineAndColumnNumber in Text.c to other places, + to make sure it is safe to change the text when the positionCallback is + called (like what is done by the new xedit file hook.c). + + Another optimization was added to the undo/redo code. Now it also merge + erases, needing yet less memory for undo, and this way, generating less + undo/redo steps. + + Removed the default translation to call the toggle-overwrite action from + TextTr.c. Only the xedit edit windows calls this translation now, instead of + every text widget. + +-- xedit -- + + Changed the auto replace feature to be a bit more easier to use. The new + behaviour is almost identical, but if the user types some text, and it is + auto replaced, only one undo step is enough to correct it. Example: + 1) user types 'nto.' + 2) text is auto replaced by 'not.' + 3) user call undo action + 4) text is converted to 'nto.' + It should be a very infrequent problem, but makes the xedit behaviour + identical to a "well known text editor", from where this feature was borrowed. + + Added a 'Check' button to the ispell interface. This button allows + checking the word in the text field. This feature was borrowed from the spell + checking interface of the Netscape html editor. + + The ispell checking interface now also asks for user interaction if there are + two identical words togheter. + + Added a status bar to the ispell interface, to give feedback to the user + about what is happening. + + Added some new resources, to let easier customization of the ispell status + bar strings. The new resources are documented in xedit.man. + +#2849 5 Jun 1999 +-- Xaw -- + + Add a OLDXAW define, to enable building a binary compatible version with + 6.1, and changes to the Imakefile, to try to keep the changes only in Xaw. + I hope it can be removed in the future. + + Add a XawVendor define, with the value "XFree86". If this is not a good + idea, please correct it an let me know. + + Add a XawVersion define. The value for the new xaw is 7000L, and for the + compatible one is 6700L (same comments as for the XawVendor define). + + Bug fixes to the undo/redo code, and code to merge erases generated by + ^H and ^D. Also, if the cursor is moved, it stops merging the text typped + in the undo buffer. + + Bug fixes to the Form widget geometry management code, to work correctly + when child widgets are removed or added at run time. + + Xaw now links with XPM by default, and the config files where changed to + enable newly compiled programs to do so. + + Added 16 pad bytes to every widget, to try to avoid binary compatability + problems in the future. + + Added a displayList resource to the Tree Widget. + + Added the functions XawTextGetSink and XawTextLastPosition, to enable a + public way to get the <TextWidget>->text.sink and <TextWidget>->text.lastPos, + since these are the most commonly private fields the programs access in + the text widget. + + Added the actions 'capitalize-word', 'donwcase-word' and 'upcase-word' to + TextAction.c. The bindings are the same as of Emacs (and the way it works). + + Corrected some problems with negative values of the <TextWidget>->text.mult. + +-- xedit -- + + Correct possible problem in the file hook.c, when interpreting the auto + replace list, that is, it was not checking the buffer size when finding + the '\' character. + + Updates for the configuration files. + + Added a 'Look' button the the ispell interface, that will by default run + "/usr/bin/bin/egrep -i '^<VALUE OF TEXT FIELD>.*$' /usr/share/dict/words" + and put up to 256 returned words in the ispell list. The behavior is + almost identical to the one in the terminal interface of ispell. + + The ispell interface works correctly with aspell now. + + Added some resources and a popup to enable changing the dictionaries in + run time. + + Added a toggle button to the ispell interface to allow changing the terse + mode in run-time. + + Added a 'Uncap' button, to allow adding an uncapitalized word to the + private dictionary, and enough code to do the capitalization checks inside + of xedit (to enable undo actions). + + Added a "text mode" and a "html mode". The html mode is not yet completely + finished. It must work correctly with some html specific things like + converting internally "á" to "á" and so on. I'm planning also, at + least a nroff mode too. + + The wordChars resource is set by dictionary now. + To set the word chars for the br dictionary, write something like: + *ispell*options.dictionaries.br.wordChars: <VALUE> + or + *ispell*br.wordChars: <VALUE> + or simply + *ispell*wordChars: <VALUE> + + The skipLines resource is set only for the text mode now. + To set it, write something like: + *ispell*options.formats.text.skipLines: <VALUE> + or + *ispell*options*text.skipLines: <VALUE> + or simply + *ispell*skipLines: <VALUE> + + +#2877 12 Jun 1999 +-- Xaw -- + + Note: The compatible old version of Xaw is not fully compatible. There + a few things that are not equal to the standard old Xaw. These are: + + The cursor code in the *Sink.c files is not identical, and the + field insertCursorOn (type Pixmap) was replaced by the field + cursor_position (type XawTextPosition). + + There are some changes in TextP.h, that include changes to the fields: + options -> left_margin + unrealize_callbacks -> pad1 + updateFrom -> update + updateTo -> pad2 + numranges -> pad3 + maxranges -> from_left + copy_area_offsets -> pad4 + + The text window does not increase its size when text is typed past + the end of the window, instead of it, it is automatically scrolled + horizontally, but this may not be enough to every usage of this + feature; xmh uses that code to make the text widget auto resize + warning popup widgets. I dont know what is better in this case, + if re-enabling the auto resize code of changing xmh to use label + widgets in the warning popups. + It is very unlikely that exists code that will have problems with these + changes in the fields of the TextWidget and the *SinkObject, but if any + code that has trouble with it exists, I will promptly make the required + changes to correct it (at least for the compatible version of Xaw). + + Several optimizations for the code to redisplay the text window in the + TextWidget. Including fixes for bugs in the XawTextScroll function, and + making it really works. Previous versions of the library have made this + function ineffective, because it was always redrawing everything when + the text window was scrolled. The optimizations should be more noticeable + when running some application that uses the TextWidget (like xedit) on + slow hardware, or over slow connections. + + Corrections for the FormWidget geometry management code, to work correctly + in the old version of Xaw, and some bug fixes for the new Xaw. Also added + 8 pad bytes to the FormConstraintsPart structure, to have space for extra + information on possible future optimizations for the FormWidget geometry + management code. + + Some fixes for the OLDXAW define in the SimpleMenuWidget code, that was + not hiding some of the new fields introduced in the new Xaw code. + + Some corrections for the code handling the necessity of having scrollbars + in the text widget, and bug fixes for cases where the scrollbars were not + being updated when the text window contents were changed. + + Re-enabled code to also process GraphicsExpose events in the text code. It + became required due to the optimizations in the text redisplay code. + + Several fixes in TextAction.c, for symbols that were not being included + in the compatible version of the library, and for symbols that were being + included with no need. + + Fixes for the form-paragraph action, in the old Xaw code. + +-- xedit -- + + Some bug fixes for the ispell undo code, to avoid deferencing a NULL pointer + in the function IspellCheckUndo. + + Added code to handle correctly &<VALUE>; in ispell.c, when using the html + mode. + + Fixed some compile time warnings, and updated the code for setting the + scrollbars in options.c. + + +#2899 19 Jun 1999 +-- Xaw -- + + Changed all the 'char pad[<number>]' to 'XtPointer pad[<number>/4]' to + make sure 64 bit machines will not have binary compatibility problems before + the 32 bit ones. + + Added a new static function 'WritePiecesToFile' to AsciiSrc.c, to avoid + allocation of temporary memory. This is useful when editing very large + files (I have some people using xedit on text files that can have up to + 80,000 lines). + + Added more some optimizations to AsciiSrc.c:Scan, to try to get the maximum + speed of this function. + + Added a new function to the displayList's, called 'image', that will tile + pixmaps on the widget. It is documented in Xaw.man. + + Several widget classes did not have a 'extension' field. I added it to them. + The first usage of this field that I'm planning is to extend the *Src and + *Sink objects to handle formatted text, and add text properties, like + foreground, background, font and so on. + + Fixed a bug in MultiSrc.c, that was crashing Xaw after the first character + was typed, or if text was removed. + + Some minor changes to SimpleMenu.c, to work properly with very large menus. + + Fixed some bugs that were caused by my previous optimizations of the text + redisplay code. + + Bug fixes and optimizations to TextPop.c, there were some cases that the + function XawTextDisableRediplay was being called, but XawTextEnableRedisplay + was not being called later because of a error condition (the error + conditions were only warnings). ++ Updates to Xaw.man. + +-- xedit -- + + Fixed a memory leak when freeing list widget strings. The code was not + releasing the memory of the string at offset 0, in the list. + + Changed the way the ispell undo code handles the terse mode, to not need + to make the toggle button insensitive. + + Updated xedit.man. + + +#2932 26 Jun 1999 +-- Xaw -- + + Added a new tip resource to the SimpleWidget. This may also be seen as + a test of the binary compatibility issues. Besides of being a new feature, + it cannot cause problems with old binaries, because the code is only + called if the tip resource is set to any SimpleWidget subclass. If the + tip resource is set or reset, the SimpleWidget code will call one of the + two new functions XawTipEnable or XawTipDisable. + + Added 3 new files: Tip.c, Tip.h and TipP.h. These files are used only + by the new Xaw. + + Updates to Xaw.man, including a problem with accented characters on SunOS. + +-- xedit -- + + Added resource configurations to show the new tip code in Xaw. + + Some fixes to ispell.c, to make it more previsible/user-friendly. + + Fixes xedit.man to avoid problems with accented characters. + + +#2964 3 Jul 1999 +-- Xaw -- + + Fix for problem found in the search/replace dialog when using splitted + windows in xedit. + + Added initialization for the display_list field of the Tree widget. + +-- xedit -- + + Fixed some problems in the undo code of ispell interface. + + +#2999 10 Jul 1999 +-- Xaw -- + + Added code to check the return value of XAllocColor and XAllocNamedColor in + Pixmap.c. + + Reverted back some code, and did a carefull review of the code in TextPop.c + to avoid the possibility of calling XawTextDisableRedisplay, and not calling + XawTextEnableRedisplay later (due to errors or end of file reached). + + Added code to TextSrc.c, to use two static variables, that represent a new + line in 8 bits and wchar_t, to avoid allocating memory in the undo buffers + to store only a new line. + + Small change in the behavior of the Tip widget, to not unmap the tip window + when the cursor is moved. + +-- Xmu -- + + Fixed a bug and a typo in the XmuToupper macro. + +-- xedit -- + + Small update to the Xedit-sample file. + + Fixed a bug in the ispell code that checks for repeated words. + + +#3122 14 Aug 1999 +-- Xaw -- + + Mixed fonts and colors can be used in the text widget (currently only + in the Ascii*Object). + + Added the XawTextAnchor, XawTextEntity, XawTextProperty, XawTextPropertyList, + XawTextPaintStruct, XawTextPaintList and XawTextPropertyInfo structures to + Xaw, to be used in the new text code. + + Added the functions XawTextSourceAddAnchor, XawTextSourceNextAnchor, + XawTextSourcePrevAnchor, XawTextSourceRemoveAnchor and + XawTextSinkConvertPropertyList, that probably should not be used outside of + Xaw. + + Added the functions XawTextSourceFindAnchor, XawTextSourceAnchorAndEntity, + XawTextSourceAddEntity, XawTextSourceClearEntities and XawTextSinkGetProperty + that are probably the ones that should be most used in programs. + + Italic fonts should be always displayed correctly. + + The text widget cursor is now displayed with a gc with the Xor function, to + avoid unnecessary computation/redrawing. + + Most changes were done in the {Ascii,Text}{Src,Sink}Object, but the text + widget was also a bit modified for things like automatically changing the + number of lines in the line table when needed. + +-- Xmu -- + + Fixed bug in Clip.c, that could cause a SEGV. + +-- xedit -- + + Added the file c-mode.c, to interface with the new Xaw text code, and show + what can be done when interfacing that new code. + + Added the necessary code to util.c and options.c to let the user select + if he or she wants to use the color/font syntax highlight in the C/C++ mode. + + +# 26 Aug 1999 + +--Xaw-- + + Added initial support for two new XawTextEntity attributes, that enable + hidden text and replaced text. This initial support was the minimum + required to get the new html mode in xedit working. A lot of code does + math with text positions, and became broken with the addition of these + two attributes. Since only code that knows about these two attributes + should use it, it is only a question to fix the remaining code in + Xaw/xedit. + + Bug fixes to AsciiSink.c:PreparePaint to work correctly with tabs and + the two new entity attributes. + + Disabled the translation "c<Key>q,<Key>Tab" of the search/replace popup. + This action is already done by the translation "<Ctrl>Q,<Key>" that I added + to TextTr.c. Disabling that translation has the advantage that now it + is possible to replace ^Ms by nothing. + + Added some new functions to TextSink.c. The functions XawTextSinkCopyProperty, + XawTextSinkAddProperty and XawTextSinkCombineProperty are candidates to being + public in the future, but, there is a problem when using + XawTextSinkCombineProperty, that requires the AsciiSinkObject having the + correct XawTextPropertyList, what can generate a "chicken and egg" like + problem (I did some hacks in xedit to have the first html-mode version + working). + + Added several new flags to the XawTextProperty attributes, and a new field, + called xlfd_mask. + + Some bug fixes to XawTextSourceReplace and to the code to manage the + XawTextAnchor e XawTextEntity structures. The form-paragraph, called with + M-Q does several consecutive text changes, and was very useful to find bugs. + + The flag XAW_TENTF_REPLACE is a hack for XawTextSourceAddEntity currently. + The function XawTextSourceAddEntity will probably change its parameters + to receive a structure pointer, or a pointer parameter. + +--xedit-- + + Fixed some bugs in c-mode.c. Again, this patch fixes all the bugs I have + found. + + Added the html-mode.c file to xedit. The html-mode is in its initial steps. + It is not usable yet, but should not core-dump or leak memory (unless you + try to edit the file, then, I cannot say what will happen). The html mode + should be used only to see a rendered version of the file, but, there are + several markups not implemented. To be usable, it must yet understand at + least <ul>, <ol>, <li>, <dl>, <dd>, <hr> and the table tags. + + + +$XFree86: xc/lib/Xaw/Changelog,v 3.32 1999/08/28 09:00:26 dawes Exp $ |
