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 :(.

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.

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.

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 3.31 1999/08/15 13:00:31 dawes Exp $ diff --git a/nx-X11/lib/Xaw/Command.c b/nx-X11/lib/Xaw/Command.c new file mode 100644 index 000000000..fdab1b1ba --- /dev/null +++ b/nx-X11/lib/Xaw/Command.c @@ -0,0 +1,660 @@ +/* $Xorg: Command.c,v 1.5 2001/02/09 02:03:43 xorgcvs Exp $ */ + +/*********************************************************** + +Copyright 1987, 1988, 1994, 1998 The Open Group + +Permission to use, copy, modify, distribute, and sell this software and its +documentation for any purpose is hereby granted without fee, provided that +the above copyright notice appear in all copies and that both that +copyright notice and this permission notice appear in supporting +documentation. + +The above copyright notice and this permission notice shall be included in +all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

This +release by the X.org Foundation includes additions and modifications +originally made for The XFree86 Project, Inc. This manual page describes +these changes as well as some of the common interfaces between its version +and the previous X Consortium release (Xaw6). +.SH ACTIONS +All of the \fIXaw\fR widgets now have the additional translations +.B call-proc, declare, get-values +and \fBset-values\fP. The syntax for these actions is: +.PP +.I action-name \fP(\fIboolean-expression\fP, \fIarguments\fP) +.PP +\fBAction-name\fP is one of \fIcall-proc\fP, \fIdeclare\fP, +\fIget-values\fP or \fIset-values\fP. +.PP +\fBBoolean-expression\fP is composed with the operators \fI|\fR (or), \fI&\fR +(and), \fI^\fR (xor), and \fI~\fR (not). The operands can be a variable name, +which starts with a \fI$\fR; a resource name without the bindings \fI.\fP +or \fI*\fP; or a constant name, including \fImine\fP (event->xany.window +== XtWindow(widget)), \fIfaked\fP (event->xany.send_event != 0), \fItrue\fP (1) +and \fIfalse\fP (0). +.PP +\fBArguments\fP are self-explanatory; when starting with a \fI$\fP they name +a variable, otherwise, they indicate a resource name. +.TP 8 +.B call-proc \fP(\fIboolean-expression\fP, \fIprocedure-name\fP) +This action allows the evaluation of a boolean expression in the first +parameter before calling a action procedure. The procedure is only called +if the expression evaluates as true. Example: +.br +.I call-proc("$inside & $pressed", notify) +.TP 8 +.B declare \fP(\fIboolean-expression\fP, \fIvariable\fP, \fIvalue\fP, ...) +This action is used to create new variables or change their values. Any +number of variable-value tuples may be specified. Example: +.br +.I declare(1, $pressed, 1) +.TP 8 +.B get-values \fP(\fIboolean-expression\fP, \fIvariable\fP, \fIvalue\fP, ...) +This action reads a widget resource value into a variable. Any number of +variable-value tuples may be specified. Example: +.br +.I get-values(1, $fg, foreground, $bg, background) +.TP 8 +.B set-values \fP(\fIboolean-expression\fP, \fIvariable\fP, \fIvalue\fP, ...) +This action sets a widget resource to the given value, which may be a +variable. Any number of variable-value tuples may be specified. Example: +.br +.I set-values(1, foreground, $bg, background, $fg) +.PP +Here is a sample translation to make a label widget behave like a button: +.PP +.nf +<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) +.fi +.SH DISPLAY LISTS +All of the \fBXaw\fP widgets have now the additional resource +\fIdisplayList\fP. This resource allows drawing the widget decorations +using commands embedded in a resource string. The displayList resource has +the syntax: +.PP +\fI[class-name:]function-name arguments[[{;\\n}]...]\fP +.PP +\fBClass-name\fP is any registered set of functions to draw in the widget. +Currently the only existing class is \fIxlib\fP, which provides access to +the Xlib drawing primitives. +.PP +\fBFunction-name\fP is the drawing or configuration function to be called, +described bellow. +.PP +\fBArguments\fP may be anything suitable to the displayList function being +called. When the function requires a coordinate, the syntax is +\fI{+-}<integer>\fP or \fI<integer>/<integer>\fP. Examples: +.nf + +0,+0 top, left + -0,-0 bottom, right + -+10,-+10 bottom+10, right+10 + +0,1/2 left, vertical-center +.fi +.TP 8 +.B arc-mode \fPmode +Sets the arc mode. Accepted \fImode\fPs are "pieslice" and "chord", which +set the arc to ArcPieSlice or ArcChord, respectively. Example: +.br +.I arc-mode chord +.TP 8 +.B bg \fPcolor-spec +.TQ +.B background \fPcolor-spec +Sets the background color. \fIcolor-spec\fP must a valid color +specification. Example: +.br +.I background red +.TP 8 +.B cap-style \fPstyle +Sets the cap style. Accepted \fIstyle\fPs are "notlast", "butt", "round", +and "projecting", which set the cap style to CapNotLast, CapBut, CapRound +or CapProjecting, respectively. Example: +.br +.I cap-style round +.TP 8 +.B clip-mask \fPpixmap-spec +Sets the pixmap for the clip mask. Requires a pixmap parameter, as +described in the \fBPIXMAPS\fP section below. Example: +.br +.I clip-mask xlogo11 +.TP 8 +.B clip-origin \fPx,y +Sets the clip x and y origin. Requires two arguments, the x and y +coordinates. Example: +.br +.I clip-origin 10,10 +.TP 8 +.B clip-rects \fPx1,y1,x2,y2 [...,xn,yn] +.TQ +.B clip-rectangles \fPx1,y1,x2,y2 [...,xn,yn] +Sets a list of rectangles to the clip mask. The number of arguments must +be a multiple of four. The arguments are coordinates. The parser +calculates the width and height of the rectangles. Example: +.br +.I clip-rects 0,0,10,20, 20,10,30,30 +.TP 8 +.B coord-mode \fPmode +Changes the coord mode for \fIfill-polygon\fP, \fIdraw-lines\fP, and +\fIdraw-points\fP. Accepted parameters are "modeorigin" and "previous", +that sets the coord mode to CoordModeOrigin or CoordModePrevious, +respectively. Example: +.br +.I coord-mode previous +.TP 8 +.B copy-area \fP{pixmap-spec|.},dstx,dsty[,x2,y2,srcx,srcy] +Calls XCopyArea. The character \fI.\fP means copy the window contents; +pixmap-spec is as defined in the \fBPIXMAPS\fP section below. \fIX2\fP and +\fIy2\fP are the coordinates of the end copy, not the width and height; if +not defined, the parser calculates them. \fIsrc_x\fP and \fIsrc_y\fP +default to zero. Example: +.br +.I copy-area Term,10,10 +.TP 8 +.B copy-plane \fP{pixmap-spec|.},dstx,dsty[,x2,y2,srcx,srcy,plane] +Calls XCopyPlane. The character \fI.\fP means copy the window contents; +pixmap-spec is as defined in the \fBPIXMAPS\fP section below. \fIX2\fP and +\fIy2\fP are the coordinates of the end copy, not the width and height; if +not defined, the parser calculates them. \fIsrc_x\fP and \fIsrc_y\fP +default to zero. \fIPlane\fP defaults to one. Example: +.br +.I copy-plane star,10,10 +.TP 8 +.B dashes \fPi1[...,in] +Sets the dashes for line drawing. Accepts up to 127 arguments. Example: +.br +.I dashes 3,7 9,10 +.TP 8 +.B draw-arc \fPx1,y1,x2,y2[,start-angle,end-angle] +Draws an arc. The four first arguments are the rectangle enclosing the +arc. The two remaining arguments, if specified, are the start and end +angle, in degrees. Example: +.br +.I draw-arc +0,+0,-1,-1,0,90 +.TP 8 +.B draw-rect \fPx1,y1,x2,y2 +.TQ +.B draw-rectangle \fPx1,y1,x2,y2 +Draws a rectangle. Requires four arguments, which are the start and end +coordinate pairs. Example: +.br +.I draw-rect +1,+1,-5,-5 +.TP 8 +.B draw-string \fPx,y,"string" +Draws a text string. Requires three arguments, a x coordinate, a y +coordinate, and a string. Strings that have white space can be quoted with +the \fI"\fP character; the backslash character \fI\\\fP can also be used, +but it will be necessary escape it twice. Example: +.br +\fI draw-string 10,10, "Hello world!"\fP +.TP 8 +.B exposures \fPboolean +Sets graphics exposures in the GC. Allowed parameters are a integer or the +strings "true", "false", "on" and "off". Example: +.br +.I exposures true +.TP 8 +.B fill-arc \fPx1,y1,x2,y2[,start-angle,end-angle] +Like \fIdraw-arc\fP, but fills the contents of the arc with the currently +selected foreground. Example: +.br +.I fill-arc +0,+0,-1,-1,0,180 +.TP 8 +.B fill-poly \fPx1,y1 [...,xn,yn] +.TQ +.B fill-polygon \fPx1,y1 [...,xn,yn] +Like \fIdraw-lines\fP, but fills the enclosed polygon and joins the first +and last point, if they are not at the same position. Example: +.br +.I fill-poly +0,+10, +10,+20, +30,+0 +.TP +.B fill-rect \fPx1,y1,x2,y2 +.TQ +.B fill-rectangle \fPx1,y1,x2,y2 +Like \fIdraw-rect\fP, but fills the contents of the rectangle with the +selected foreground color. Example: +.br +.I fill-rect +10,+10,-20,-20 +.TP 8 +.B fill-rule \fPrule +Sets the fill rule. Accepted parameters are "evenodd" and "winding", which +set the fill rule to EvenOddRule or WindingRule, respectively. Example: +.br +.I +fill-rule winding +.TP 8 +.B fill-style \fPstyle +Sets the fill style. Allowed parameters are "solid", "tiled", "stippled" and +"opaquestippled", which set the fill style to FillSolid, FillTiled, +FillStippled or FillOpaqueStippled, respectively. Example: +.br +.I fill-style tiled +.TP 8 +.B font \fPfont-spec +Sets the font for text functions. Example: +.br +.I font -*-*-*-R-*-*-*-120-*-*-*-*-ISO8859-1 +.TP 8 +.B fg \fPcolor-spec +.TQ +.B foreground \fPcolor-spec +Like \fIbackground\fP, but sets the current foreground color. Example: +.br +.I foreground blue +.TP 8 +.B mask +This command is useful when you want to draw only in the region that really +needs to be repainted. Requires no arguments. +.TP 8 +.B function \fPfunction-spec +Sets the specific GC function. Allowed parameters are "set", "clear", "and", +"andreverse", "copy", "andinverted", "noop", "xor", "or", "nor", "equiv", +"invert", "orreverse", "copyinverted" and "nand", which set the function to +GXset, GXclear, GXand, GXandReverse, GXcopy, GXandInverted, GXnoop, GXxor, +GXor, GXnor, GXequiv, GXinvert, GXorReverse, GXcopyInverted or GXnand, +respectively. Example: +.br +.I function xor +.TP 8 +.B join-style \fPstyle +Sets the join style. Allowed parameters are "miter", "round" and "bevel", +which set the join style to JoinMiter, JoinRound and JoinBevel, +respectively. Example: +.br +.I join-style round +.TP 8 +.B image \fP{pixmap-spec},xs,ys,[xe,ye] +This function is implemented as a way to quickly compose complex +decorations in widgets. \fIPixmap-spec\fP is as defined in the +\fBPIXMAPS\fP section below. \fIxs\fP and \fIys\fP are the coordinates from +where to start copying the pixmap; \fIxe\fP and \fIye\fP are optional (they +default to xs + pixmap.width and ys + pixmap.height, respectively). If the +pixmap has a mask, the copy is masked accordingly. Example: +.br +.I image pixmap.xpm,0,0,20,20 +.TP 8 +.B line \fPx1,y1,x2,y2 +.TQ +.B draw-line \fPx1,y1,x2,y2 +Draws a line with the current foreground color. Requires four arguments, +the starting and ending coordinate pairs. Example: +.br +.I line +0,+0, -1,-1 +.TP 8 +.B line-width \fPinteger +Selects a line width for drawing. Example: +.br +.I line-width 2 +.TP 8 +.B line-style \fPstyle +Sets the line style. Accepted parameters are "solid", "onoffdash" and +"doubledash", which set the line style to LineSolid, LineOnOffDash or +LineDoubleDash, respectively.

The number of parameters must be multiple +of 4. Example: +.br +.I segments +1,+2,+1,-3, +2,-2,-3,-2 +.TP 8 +.B shape-mode \fPmode +Sets the shape mode used in \fIfill-polygon\fP. Accepted parameters are +"complex", "convex" or "nonconvex", which set the shape mode to Complex, +Convex or Nonconvex, accordingly. Example: +.br +.I shape-mode convex +.TP 8 +.B stipple \fPpixmap-spec +Sets the pixmap for a stipple. Requires a pixmap parameter, as described +in the \fBPIXMAPS\fP section below.

Example: +.br +.I tile xlogo11?foreground=red&background=gray80 +.TP 8 +.B ts-origin \fPx,y +Sets the tile stipple x and y origin. Requires two arguments, a x and y +coordinate. Example: +.br +.I ts-origin 10,10 +.TP 8 +.B umask +Disables the GC mask, if it has been set with the command \fImask\fP. +Requires no arguments. +.PP +Example for drawing a shadow effect in a widget: +.nf +foreground gray30;\\ +draw-lines +1,-1,-1,-1,-1,+1;\\ +foreground gray85;\\ +draw-lines -1,+0,+0,+0,+0,-1 +.fi +.SH PIXMAPS +A String to Pixmap converter has been added to \fBXaw\fP. This converter +is meant to be extended, and has enough abstraction to allow loading +several image formats. It uses a format that resembles a \fIURL\fP, with +the syntax: +.PP +.I [type:]name[?arg=val[{&}...]] +.PP +\fBType\fP can be one of \fIbitmap\fP, \fIgradient\fP or \fIxpm\fP. +.PP +\fBName\fP may be a file name, or, in the case of type \fIgradient\fP, may be +either \fIvertical\fP or \fIhorizontal\fP. +.PP +\fBArg=val\fP is a list of arguments to the converter. An argument list is +preceded by a question mark, and multiple arguments are separated by +ampersands. The most common arguments are \fIforeground\fP and +\fIbackground\fP. Gradients also support the arguments \fIstart\fP and +\fIend\fP (colors with which to start and end the gradient); the +\fPsteps\fP argument, to allow using less colors; and the \fIdimension\fP +argument to specify the size of the gradient. The \fIxpm\fP converter +understands the \fIcloseness\fP argument, which aids in using fewer colors +(useful if you have a limited colormap). +.SH TEXT WIDGET +Most of the changes to this version of the Xaw library were done in the +TextWidget, TextSrcObject, TextSinkObject and related files. +.PP +A couple of highly visible changes in the Text widget are due to many bugs +in the Xaw6 implementation involving scrollbars and auto-resizing. +Scrollbars being added or removed caused several problems in keeping the +text cursor visible, and in Xaw6 it was very easy to have a widget thinking +the cursor was visible, when it was not. Also, permitting automatic +resizing of the widget to a larger geometry created other problems, making +it difficult to have a consistent layout in the application, and, if the +window manager did not interfere, windows larger than the screen could +result. Therefore, some functionality involving scrollbars and +auto-resizing has been disabled; see the section on new and modified +Text widget resources below. +.PP +The Text widget's default key bindings were originally based on the Emacs +text editor. In this release, even more operations familiar to Emacs users +have been added. New text actions include: +.TP 8 +.B indent +Indents text blocks. Not bound by default. The Text widget also does not +attempt to perform auto-indentation of its source object by default. +.TP 8 +.B keyboard-reset +Resets the keyboard state. Reverts the action multiplier to 1, and if undo +is enabled, toggles between undo and redo. Bound by default to +\fIControl<Key>G\fP. +.TP 8 +.B kill-ring-yank +In this version of Xaw, text killed in any text field is kept in memory, +allowing cut and paste operations internally to the program between text +fields. Bound by default to \fIMeta<Key>Y\fP. +.TP 8 +.B numeric +Listed here only for purposes of documentation. Called by default when one +of the characters \fI1, 2, 3, 4, 5, 6, 7, 8, 9, 0,\fP or \fI-\fP is typed, +allowing composition of the multiplication number of text actions. +.TP 8 +.B set-keyboard-focus +Sets the input focus of the top level widget to the text field. Not +enabled by default, but bound to the \fI<Btn1Down>\fP event. +.TP 8 +.B toggle-overwrite +Toggles overwrite mode. In overwrite mode, any text inserted in a text +field will replace existing text. Bound by default to \fI<Key>Insert\fP. +.TP 8 +.B undo +Sets the \fIenableUndo\fP resource of the textSrcObject. Not enabled by +default, but bound to \fIControl<Key>_\fP. +.PP +New and modified Text widget resources include: +.TP 8 +.B justify (\fPClass\fB Justify) +Sets the text justification. Can be one of \fIleft, right, center\fP, or +\fIfull\fP. Only enabled when the \fIautoFill\fP resource is set, and the +resources \fIleftColumn\fP and \fIrightColumn\fP are correctly set. +.TP 8 +.B leftColumn (\fPClass\fB Column) +Specifies the left column at which to break text. Text lines started with +an alphanumeric character will automatically start at this column. +.TP 8 +.B positionCallback (\fPClass\fB Callback) +Allows installation of a callback to be called every time the cursor is +moved, and/or the file changes its size. The callback is called with a +pointer to a structure containing the following data: +.nf +typedef struct { + int line_number; + int column_number; + XawTextPosition insert_position; + XawTextPosition last_position; + Boolean overwrite_mode; +} XawTextPositionInfo; +.fi +This callback is intended to help programmers write text editors based +on the Xaw widget set. +.TP 8 +.B resize (\fPClass\fB Resize) +No longer supported, but recognized for backward compatibility with +resource specifications written for the Xaw6 Text widget. +.TP 8 +.B rightColumn (\fPClass\fB Column) +Specifies the right column at which to break text. Text lines started with +an alphanumeric character will automatically end at this column. +.TP 8 +.B scrollHorizontal (\fPClass\fB Scroll) +.TQ +.B scrollVertical (\fPClass\fB Scroll) +These resources control the placement of scrollbars on the left and bottom +edges of the Text widget. They accept the values \fIXawtextScrollAlways\fP +and \fIXawtextScrollNever\fP. A converter is registered for this resource +that will convert the following strings: \fIalways\fP and \fInever\fP. The +value \fIXawtextScrollWhenNeeded\fP (and \fIwhenNeeded\fP, recognized by +the converter), is accepted for backwards compatibility with resource +specifications written for the Xaw6 Text widget, but ignored (effectively +treated as \fIXawtextScrollNever\fP). +.SH TEXT SOURCE OBJECT +The textSrcObject allows display of its contents to more than one window, +and also stores undo information. The new resources for the textSrcObject +are: +.TP 8 +.B callback (\fPClass\fB Callback) +Previous versions of Xaw had this resource in subclasses of the TextSource +object. This was changed to make it possible to tell the callback the +state of the text when undo is enabled. +.TP 8 +.B enableUndo (\fPClass\fB Undo) +A boolean resource that enables or disables the undo function. The default +value is False. +.TP 8 +.B sourceChanged (\fPClass\fB Changed) +Like the callback resource, this resource was previously in subclasses of +the TextSource object. It is now in the textSrcObject to control the +changed/unchanged state when undo is enabled. +.SH TEXT SINK OBJECT +The textSinkObject subclasses asciiSinkObject and multiSinkObject have been +changed slightly to use a new cursor shape (no longer a caret at the +baseline) that indicates the input focus of the text widget, and allow +specification of the cursor color. The new resource is: +.TP 8 +.B cursorColor (\fPClass\fB Color) +Sets the cursor color of the text. This color is also used to draw +selected text. +.SH SIMPLE MENU WIDGET +The simpleMenuWidget algorithm to lay out menu entries has been changed to +enable multiple columns when a single column does not fit on the screen. +It was also modified to enable submenus. +.SH SME BSB OBJECT +A new resource has been added to the smeBSBObject to allow binding submenus +to it. The new resource is: +.TP 8 +.B menuName (\fPClass\fB MenuName) +Specifies the name of the popup widget to be popped up when the pointer is +over the menu entry, or NULL. Note that the named menu must be a child of +the popup parent of the smeBSBObject. +.SH RESTRICTIONS +.B Xaw +is actively being developed. Programs intending to be fully compatible +with future releases of the Xaw library should use only the public +interfaces. While widget subclassification is not a bad thing, and +sometimes an encouraged programming practice, programs that access private +data structures may have problems with newer releases in the current stage +of +.I Xaw +development. Efforts are being made to avoid such problems and to guarantee +that newer releases will be source and binary compatible. +.SH AUTHORS +The original X Consortium version of the Athena Widget Set and its +documentation were the work of many people, including Chris D.
