The TCL (Tool Command Language) provides a powerful platform for creating integration applications that tie together diverse applications, protocols, devices, and frameworks. When paired with the Tk toolkit, TCL provides a fastest and powerful way to create cross-platform GUI applications. TCL can also be used for a variety of web-related tasks and for creating powerful command languages for applications.

This software is distributed in two modes:
  • as compressed package that you have to download and manually install; if prerequisites are required, you will have to manually install them too;
  • as RPM package; you can install it using your favorite rpm package manager, that will take care to download and install both the software and its prerequisites.
Choose the installation mode that you prefer. Please note that not all the versions are available in both the installation modes.

Tcl7.6/Tk 4.2 for OS/2 PM, 2nd release (executables) Last update: 27 July 1999 Illya Vaes Martin Luther Kingstate 23 6716 NA Ede The Netherlands ivaes@hr.nl (work; this was/is a free time project) Welcome to release 2 of Tcl 7.6p2/Tk 4.2p2 for OS/2 PM. Installation: Unzip the archive, making sure directories are preserved (PKzip needs -d). As long as the binaries (tclsh76.exe, tclshpm76.exe and wish42.exe) are started in the same directory as their DLLs (tcl76.dll and tk42.dll), you don't need to do anything else. If you want to be able to start them from anywhere, you have to put the directory in your path or put the executables in a directory that already is in your PATH (and the DLLs in your LIBPATH). In such a case, it becomes quite likely that Tcl will not be able to find out the location of its library by itself, so you're recommended to add environment variables for those to your CONFIG.SYS (if you want them to persist, that is), e.g. SET TCL_LIBRARY=E:/TclTk/lib/tcl7.6 and TK_LIBRARY=E:/TclTk/lib/tk4.2. Paths in Tcl/Tk use _forward_ slashes, in this port too! You can change to a different drive (and, if you like to a different directory there at the same time) by saying e.g. "cd e:/tk4.2/os2". Tcl uses the environment variable TEMP (native OS/2 format, backslashes) to determine the directory in which to make temporary files (eg. for use with pipelines). This port has been compiled with EMX 0.9c, and requires its EMXLIBCM.DLL and EMX.DLL (or those of a higher version). Kudos to Eberhard Mattes for EMX. Compiling: To compile the source yourself, you need the Tcl and Tk source from Sun. After extracting it (gzip -c -d tcl7.6p2.tar.gz | tar xvf -) on your drive, unzip the source-zip of Tcl/Tk for OS/2 on the same drive, go to tcl7.6\os2 and execute 'gmake'. Obviously, you need gzip, tar, unzip and gmake for this, as well as EMX. Also, \OS2\RC.EXE was used. Using the DLLs in other applications: To make use of tcl76.dll and/or tk42.dll in other applications, you have to link the executables of those with tcl76.lib and/or tk42.lib (the import libraries corresponding to the DLLs), and include code in your EXE to initialize and use Tcl/Tk (or initializing your own package, depending on how you look at it), as is shown in the file tclAppInit.c and tkAppInit.c. See the Makefile for files to link with your executable, taking note of the way a command-line Tcl-application is built (eg. always with tclOS2Main.c with or without defining CLI_VERSION, tclOS2Console.c only when building a PM-based Tcl application). If, for some reason, you only have tcl76.dll and/or tk42.dll and not the .lib files, then you can generate the latter by using emxexp and emximp (2x). See the Makefile (targets $(TKBASE).def, $(TKBASE).imp and $(TKLIB)) for how to. NOTES ===== - When you are in TclshPM, you can say "load <full-path-to-tk42.dll>" and you have gotten all of Tk at your disposal (without wish's console). Eg. "load E:/TclTk/bin/tk42.dll". - The native File Dialogs don't really support a "default extension" (like in Windows), probably because OS/2 has *real* file types not related to the filename. The code around the File dialogs will however add any given default extension to any given initial file if that has no extension yet. If the user then types in a file without an extension or choose one, then _no_ extension is added (since the file dialog gives no such control). This could probably be added after the dialog (adding the extension then), but who am I to second-guess the user... Anyway, the Mac ignores extensions. - Because of difference in fonts and such, layout of scripts may turn out wrong. This includes the test script hscale.tcl for instance, where the arrow that follows the scale starts further to the left than the scale. Changing the "-wraplength" option to the label $w.msg from 3.5i to 300 makes it (approx.) correct. - Fonts need to be specified in the same case as Presentation Manager knows, eg. Helvetica (not helvetica), Times New Roman (not times), ... - Mouse buttons are those known to OS/2, ie. Button 2 is the *right* button, not the middle one as in X. Of course, for consistent lefties (I only write left-handed) Button 2 is the left button ;-) Programs that are known to run (with or without minor modification) ------------------------------------------------------------------- Some apps seem to get into an infinite loop upon closing the main window with double clicking the window menu button (the icon topleft). At least Paradigm Visual Make does this. Visual Tcl and XF correctly intercept the WM_DELETE_WINDOW and/or other WM_PROTOCOLS. - TkCon 1.03 The switch statement setting the envHome variable ("Determine what directory the resource file should be in") must be augmented with an "os2" pattern: "windows - os2 - unix { set envHome HOME }" instead of "windows - unix { set envHome HOME }" And set the HOME environment variable in CONFIG.SYS ofcourse... - SpecTcl 1.1 Several tcl_platform checks need to have OS/2 added, which is easiest in case statements by adding a line with "os2 -" before the "windows" case, thereby making the Windows code pertinent to OS/2 too. - Visual Tcl 1.08 A smaller font must be specified to get the texts to show in their entirety in the "Geometry Information" dialog, eg {8.Helv}. - Paradigm Visual Make (pvm_12). Needs to have the testing for the platform to be augmented with OS/2, with the same actions as for Windows. - XF 4.0pl1. Needs to have "exec command.com..." changed to "exec cmd.exe" in src/xfglobals.tcl and src/xfmisc.tcl (failure to do this will crash the program), and the scripts xfhardcopy/xfhardcopy.tcl and xfappdef/xfappdef.tcl need to have their wish modified to wish42.exe. TESTS THAT FAIL =============== Tk: - Some tests fail because a default font is chosen instead of returning an error. - Some tests fail because the fontname isn't capitalized (eg. helvetica instead of Helvetica) and so a default font is chosen. - Tests in winfo.test with winfo interps fail since X Properties are not supported (future implementation via Prf... ?). - Some tests fail because font sizes / rounding may vary between X and PM (eg. entry xview or entry index @nr with a proportional font). - imgPPM.test fails because the file isn't written in a cross-platform manner. Supposedly fixed in 8.0. - canvPsText.tcl: fails to select the correct fonts because they are specifief in lower case, while OS/2 font names start with a capital (eg. Helvetica), while 'times' should be 'Times New Roman'. Tcl: - The Tcl env.test fails (after hacking it to use printenv.exe and a path separator of ';' instead of ':') because EMX insert a variable _emx_sig, after the the contents of the environment that Tcl gets have been determined, so all results are "off" by that variable. - Format: values that would get truncated to 0 seem to be rounded upwards by EMX to the nearest non-0 value. This makes two format tests fail (ie. %3.1f and 0.01 gives 0.1 instead of 0.0, but %3.1f and 0.001 gives 0.0). Two other formats that fail concern "%#.0g" and "%#.4g", where EMX seems to take the number of digits after the decimal point more literally than the tests expect, rendering 0.0000 and 0. respectively (0.000 and 0.0 expected). Other than this, all Tcl tests work correctly. HISTORICAL CHANGES ================== Release 2 of the OS/2 port ========================== - Binary distribution (and Makefile): with maximum packing with LXLITE and icons correctly as default icons. - The CLI-version doesn't set Focus to the desktop anymore (necessitating one to explicitly change focus again to type something else in the window in which tclsh76 ran). - Error message (WinMessageBox) when the evalutation of a script that was given as an argument doesn't return TCL_OK (taken from forthcoming 8.0.5 version). - Fixed operating system version in $tcl_platform(osVersion). - Environment variable LANG set to DE_DE doesn't cause a syntex expression for eg. "expr 3.14" anymore. 7.6p2/4.2p2 =========== - Tclsh76.exe is now a command line interface (CLI) version of tclsh.exe. In this version you can*NOT* say "load tk42" and have Tk at your disposal, since this version has PM usage switched off (mutually exclusive). The previous PM implementation is now called tclshpm76.exe. Note: the CLI version has a nasty side effect of making the window in which it is run lose focus; under FeelX the window even has the active titlebar so FeelX must think the focus is there, but typing in the window has no effect. You must move your mouse out of the window and back in. - Native File Open/Save Dialog. If you use object types names as known to the WPS, you can select files based purely on their type (not extension). Note: for compatibility with existing (non-WPS aware) scripts, the initial selection is with "type" <All Files>, so the name is significant. - Sockets are now handled (in/by code) like in the Unix version, making the reliance on EMX more obvious (it was already present) because it makes the use of sockets transparent, like on Unix. - NotifyVisibility events are now only generated for windows that are showing according to PM (WinIsWindowShowing) and Tk considers mapped (TK_MAPPED). Previously, the Windows port of generating it for every TK_MAPPED child (because Windows has no equivalent of WinIsWindowShowing, only of WinIsWindowVisible, which returns true for windows that are completely obscured too) was used unchanged. Any event still has a state of VisibilityUnobscured. More accurate transition info could be generated, but in my opinion would be too expensive (both in computation and memory) compared to its use. Some changes from the 8.0 Windows version have been incorporated to fix the double Map/Unmap binding triggering in two tests in textWind.test. - The names for temporary files are now determined with tempnam(), which made eg. "exec cat << {Sample text}" work correctly. This, however, left the temporary behind since that is closed (and tried to be deleted) before the program that is reading from it (cat) exits, giving a sharing violation. Therefore, when a temp file cannot be deleted, it is added to a list of temp files as yet undeleted, to be deleted on exit. An exit procedure is registered for that, which tries to close and delete every file in the list, ignoring any errors. If that doesn't do it.... you're out of luck :-). Oh... and EMX 0.9c has TMP_MAX defined as 1000, so after so many temp files it starts over, so make sure you don't make that much at the same time... ;-) - Winfo rooty and winfo containing gave incorrect results, fixed. - Bug in XCopyPlane fixed. - Moving rectangles left spurious lines to the right (eg. widget demo, arrowhead for canvas lines editor); fixed. - Optional compiling of key-handling fixes suggested by Ilya Zakharevich (break e.g. Ctrl-X). - Fixes suggested by Ilya Zakharevich (fonts): + Consider the "10" in e.g. "10.Courier" to be pixels, not points. + Use lMaxBaselineExt as height indicator for pixmap fonts instead of emHeight. + Compile option for "display resolution correction" (ignoring what PM tells us and using a given resolution, default 72 dpi. + Default text font "10.Courier" when that "correction" is used. - The format of $tcl_platform(platform) has been changed to "os2" to make it more consistent with those of other platforms ("unix", "macintosh", "windows"). $tcl_platform(os) still returns "OS/2". - The Tclsh console now shows output sent to "stdout" or "stderr" when running interactively. The tests make use of these explicit channel names. - Transients now get a dialogborder. 7.5/4.1 ======= Fix 1 ----- - Opening files for appending truncated them. Fixed. - Bitmaps got reversed (again). XCopyPlane has to do the colours "reversed" like the Windows port, contrary to what the PM Guide and Reference states. Release ------- - Execs (usually with pretty much output) gave an OS/2 error message that the process tried to write to a non-existent pipe. Fixed by not using a named pipe but an unnamed pipe. - The socket code works. - The Tclsh console tries its best to add all output to the end, no matter where the cursor happens to be. Insert output from commands with MLM_IMPORT instead of via the clipboard, thereby not being limited to 64K. Control-C can be used to (try to) break off a script (like is necessary to regain control in the test-script remote.tcl). - Traced a (not-so) subtle bug in TclSetSystemEnv that reared its ugly head later, by running Visual Tcl 1.08 (malloc-ing space for VARIABLE=VARIABLE instead of VARIABLE=VALUE, for a lengthy value, ergo using memory that wasn't malloc-ed). Stoooopid. - Use of the command processor in environment variable COMSPEC instead of always using CMD for things not in the path (ie. likely internal commands like DIR). Still uses CMD.EXE when this can't be determined. - Array subscripts in determining system values were one off, rendering OS/2 Warp 4 as major version 4, minor version 0, revision <some-number> instead of the (documented) required 20, 40 and 0. Fixed, but "hacked" in the same way as CMD.EXE, ie. returning version 4.0 for 20.40.0. - Globbing was broken for non-current directory searches. It accepts volume-relative specs like "e:*.tk" and fills in the current directory on the drive between the ':' and '*'. It now also determines case (in)sensitivity and case (non)preservation from the file system that the directory resides on. FAT, VINES and anything it doesn't recognize are taken to be insensitive and non-preserving. NFS and EXT2FS (Linux) are taken to be sensitive and preserving, HPFS and NTFS insensitive and preserving. - Fixed "put" with a channelId in the Tclsh console. - Flashing of a new window in the corner (being displayed there and then immediately moved) fixed. Was caused by a superfluous WS_VISIBLE in the Window Style). By default windows start in upper left corner. - Overzealous looking at VK_ALTGRAF in tkOS2X.c removed. This caused any key pressed with Alt Gr (German, Dutch keyboards) to be ignored. - First code for a CLI (Command Line Interface) version of tclsh put in, but not pursued further. #ifdef-ed with CLI_VERSION. Beta 5 - 11 sept.1997 ------ - Unlike the Windows port ;-), the functionality of stippling for ARCs is implemented. - Fixed inconsistency and typo in tkOS2Pointer.c wrt. Y coordinate lastMousePos. - The format of $tcl_platform(os) has been modified again to make them more logical though now the array elements for platform and OS return the same, ie. "OS/2"; Other values: osVersion e.g. "4.0", machine "intel". Similarly, "winfo server ." returns e.g. "OS/2 4.0". No marketing names (Warp) allowed here... - Menus appear at the correct height (aligned with bottom of button). - Binding to ALT works. NB: A binding is case-sensitive: Control-Shift-x will not match anything while Control-Shift-X will. The latter is equivalent to Control-X, since you will only get X (not x) by pressing Shift. - Withdrawn windows completely disappear, ie. from the task list. - Stippling works (apart from stippled ARCs, which don't get stippled in the Windows port either). - Windows port did not look at GC values for CapStyle, JoinStyle, LineStyle. This port does. - Lines have (specified) width. This needs the "geometric line width" in OS/2, which is only used by GpiStrokePath (and GpiModifyPath), so use that. - Ctrl-X and the likes work. - Focus problem after grab fixed. I was too correct in following the "Results" section for XGrabPointer, which says to return AlreadyGrabbed if the grab didn't succeed. This should be ignored, like in the Windows version, and GrabSuccess should always be returned. (Font patch by Ilya Zakharevich assimilated) - Fonts (sigh ;-}): calculation of size was wrong. Furthermore, because of unclear / confusing GPI programming info, the check of the sizes of the available fonts wasn't done on the right value. It turns out you have to *request* the size via the lMaxBaselineExt member, while the actually used value is in lEmHeight. Am I dense or what?? Actually, the returned nominal pointsize is OK. Compile-time option (via #define) provided for ignoring a PM-provided font resolution of 120dpi, taking 96dpi instead, which is the resolution in VGA and upto ?800x600?; requested by Ilya Zakharevich. - Color images now work, including those that get split up into several before drawing (LCOLF_RGB instead of LCOLF_CONSECRGB in GpiCreateLogColorTable; LCOLF_CONSECRGB should (only) be used with Palette Manager). - Width calculation of fonts improved by using TXTBOX_BOTTOMRIGHT instead of TXTBOX_CONCAT. - Tcl: File globbing was broken because DosQueryPathInfo doesn't like ".\" for the file/directory argument. Similarly, directories weren't seen. - "option readfile" wasn't succesful with OS/2 files, but was with an .Xdefaults copied from Linux. Choked on the Return&Newline being replaced by just the Newline, yielding a "nr.of chars read" smaller than the file size, aborting the entire process. Fix necessitated changing the generic file tkOption.c, function ReadOptionFile with the corresponding (fixed) code of Tk 4.2. - Compile time option (set in makefile.emx) to use "9.WarpSans" as default font. Beta 4 ------ - A "wm withdraw" now also works when running or sourcing a script (i.e. mapping/creating in withdrawn state). Switching to a withdrawn window (eg. by using the task list) works okay. Previously only a "wm deiconify" would do the trick of exposing the client area (restoring contents). - Resizing in vertical direction fixed. When resizing to a smaller height with a menu bar involved, the menu bar disappeared (partly or entirely, depending on the size). Cause was the use of CS_SIZEREDRAW for child windows. - The default screen name is determined from the DISPLAY environment variable, if available, so scripts asking for toplevels with -screen <name> don't abort (and any toplevels without specifying a screen in an invocation of wish with the -screen <name> argument). - Double-clicking now works correctly, OS/2 PM's WM_BUTTONxDBLCLK messages get changed to both a ButtonDown and a ButtonUp event. - Fonts changed again. Presentation Parameter-style specification now fully supported: PointSize.FontName[.Attribute][.Attribute]... where Attribute is one of bold, italic, outline, strikeout, underline. Some fonts (eg. -*-Helvetica-Bold-R-Normal-*-240-*-*-*-*-*-*) didn't show up. This was because they were scaled to pointsize 0 because the 240 is in the "pixels" spot, which should be a substitute for the point size (or at least was in the Windows version), but wasn't implemented identically. An explicit point size will override it. The ascenders and descenders of scalable fonts are fixed, so they won't get progressively larger when enlarging the font. - Double ckfree because of WM_DESTROY message (caused by WinDestroyWindow in XDestroyWindow, tkOS2Window.c) fixed, care of sleuthing by Ilya Zakharevich. - Resizing works, wm minsize and wm maxsize likewise. Beta 3 ------ - Merged resources for additional pointers into the DLL. - Clicking in the console gets the focus now too (previously, only clicking the titlebar worked). - Fonts work a little bit more correct. ;-) Height, width and actually used pointsize are correct now. Without special handling, every scalable font is of point size 12! Code by Ilya Zakharevich (ilya@math.ohio-state.edu) incorporated into tkOS2Font.c, enabling the use of e.g. "10.Courier". - Images work. Funnily, they are (exquisite) greyscale on a 64K display but color on a 256 palette management. The OS/2 part is doing what Tk tells it to with regard to color though, it just gets handed grey values, so I have to assume it is working as advertised. - 'exec' was broken in Beta 2. Fixed. PM apps should be exec-ed with '&' unless they are very short-lived. Tclsh will be "listening" for output from the app and this will "lock up the queue" because of the single-threadedness. - The format of $tcl_platform(os) has been modified slightly; return values are now "Warp 3" and "Warp 4" instead of "Warp v3" and "Warp 4 (Merlin)". Other values: platform "OS/2", osVersion e.g. "4.0", machine "intel". - Temporary files are cleaned up when closed by specifying a DosClose wrapper to be called on file closure. - Humongous memory leak in TkOS2SelectPalette fixed. Beta 2 ------ - Font selection works correctly now, so that any font available through the font dialog is available. It first determines all fonts in the system (#ifdef DEBUG) / all fonts with the specified facename (#ifndef DEBUG) via GpiQueryFonts and then determines the most suitable font based on the size. Preference is given to bitmap fonts over outline (scalable) fonts for purposes of performance in using the font. When many fonts of the same facename exist, the scalable one is at the start of the "list" and the correctly sized bitmap font is at the end of the "list", this may exact a performance penalty at the time of determining the font. This is a small one-time penalty though. Fonts with a '-' in their name have to be specified by length-3-array (eg. "Conga-Normal 180 normal"). To not get stuck with a default font (ie Courier), you will need to use font names that OS/2 knows *and* use the right case: helvetica -> Helvetica or Helv Times -> Times New Roman or Tms Rmn (eg: ... -font "-Adobe-Times New Roman-medium-r-normal-*-180-*-*-*-*-*-*" ) - Colors on non-Palette management system work. Not tested on VGA but you will not get any better there... - Choosing "Close" (Alt-F4) on a torn-off menu or otherwise non-"main" window will only close that particular window, not the whole application. Beta 1 ------ No record has been maintained for bugfixes previous to this. THANKS TO ========= - Ilya Zakharevich for his critical testing. - Anna Chiara Bellini for putting an FTP server at my disposal. - Anyone not named that has assisted by beta testing and/or doing suggestions. BUGS ==== TO DO (?) (Extending port) ========================== - Accept Drag-and-Drop of files to be sourced into the console. - Have TraversalCopy and TclpCopyFile also copy Extended Attributes (EAs). - Have Shift-Insert, Shift-Delete and Ctrl-Insert act on clipboard. This means extending the "Tk Clipboard" only approach to use PRIMARY and/or SECONDARY too. Just replacing CLIPBOARD with PRIMARY has Shift-Insert working. - Global Grab doesn't turn pointer into clock outside of dialog. Possible?? - Make button 2 and 3 of the mouse switchable. To OS/2, button 2 is the right mouse button and generates a WM_BUTTON2* message, 3 is an optional middle mouse button (WM_BUTTON3*). For X, and thus XFree86 in an OS/2 Full Screen session, button 2 is the ("always available") middle button and 3 the right. - Implement a "send", either via DDE or via Pipes/Queues? - Multithreading (dual-threading: one extra thread for the message queue to stay responding to the system, coomunicating with the one that now exists which might be computing for a longer time). - The list of occupied logical font IDs is a straight array. This method will leave "holes" when freeing another font than the last one. Solution: convert to a linked list or use Tcl's hash table mechanism.

Programs that are known to run (with or without minor modification) ------------------------------------------------------------------- Some apps seem to get into an infinite loop upon closing the main window with double clicking the window menu button (the icon topleft). At least Paradigm Visual Make does this. Visual Tcl and XF correctly intercept the WM_DELETE_WINDOW and/ort other WM_PROTOCOLS. - Paradigm Visual Make (pvm_12). Needs to have the testing for the platform to be augmented with OS/2, with the same actions as for Windows. - Visual Tcl 1.08 A smaller font must be specified to get the texts to show in their entirety in the "Geometry Information" dialog, eg {8.Helv}. - XF 4.0pl1. Needs to have "exec command.com..." changed to "exec cmd.exe" in src/xfglobals.tcl and src/xfmisc.tcl (failure to do this will crash the program), and the scripts xfhardcopy/xfhardcopy.tcl and xfappdef/xfappdef.tcl need to have their wish modified to wish41.exe. HISTORICAL CHANGES ================== Fix 1 ----- - Bitmaps got reversed (again). XCopyPlane has to do the colours "reversed" like the Windows port, contrary to what the PM Guide and Reference states. Release ------- - Execs (usually with pretty much output) gave an OS/2 error message that the process tried to write to a non-existent pipe. Fixed by not using a named pipe but an unnamed pipe. - The socket code works. - The Tclsh console tries its best to add all output to the end, no matter where the cursor happens to be. Insert output from commands with MLM_IMPORT instead of via the clipboard, thereby not being limited to 64K. Control-C can be used to (try to) break off a script (like is necessary to regain control in the test-script remote.tcl). - Traced a (not-so) subtle bug in TclSetSystemEnv that reared its ugly head later, by running Visual Tcl 1.08 (malloc-ing space for VARIABLE=VARIABLE instead of VARIABLE=VALUE, for a lengthy value, ergo using memory that wasn't malloc-ed). Stoooopid. - Use of the command processor in environment variable COMSPEC instead of always using CMD for things not in the path (ie. likely internal commands like DIR). Still uses CMD.EXE when this can't be determined. - Array subscripts in determining system values were one off, rendering OS/2 Warp 4 as major version 4, minor version 0, revision <some-number> instead of the (documented) required 20, 40 and 0. Fixed, but "hacked" in the same way as CMD.EXE, ie. returning version 4.0 for 20.40.0. - Globbing was broken for non-current directory searches. It accepts volume-relative specs like "e:*.tk" and fills in the current directory on the drive between the ':' and '*'. It now also determines case (in)sensitivity and case (non)preservation from the file system that the directory resides on. FAT, VINES and anything it doesn't recognize are taken to be insensitive and non-preserving. NFS and EXT2FS (Linux) are taken to be sensitive and preserving, HPFS and NTFS insensitive and preserving. - Fixed "put" with a channelId in the Tclsh console. - Flashing of a new window in the corner (being displayed there and then immediately moved) fixed. Was caused by a superfluous WS_VISIBLE in the Window Style). By default windows start in upper left corner. - Overzealous looking at VK_ALTGRAF in tkOS2X.c removed. This caused any key pressed with Alt Gr (German, Dutch keyboards) to be ignored. - First code for a CLI (Command Line Interface) version of tclsh put in, but not pursued further. #ifdef-ed with CLI_VERSION. Beta 5 - 11 sept.1997 ------ - Unlike the Windows port ;-), the functionality of stippling for ARCs is implemented. - Fixed inconsistency and typo in tkOS2Pointer.c wrt. Y coordinate lastMousePos. - The format of $tcl_platform(os) has been modified again to make them more logical though now the array elements for platform and OS return the same, ie. "OS/2"; Other values: osVersion e.g. "4.0", machine "intel". Similarly, "winfo server ." returns e.g. "OS/2 4.0". No marketing names (Warp) allowed here... - Menus appear at the correct height (aligned with bottom of button). - Binding to ALT works. NB: A binding is case-sensitive: Control-Shift-x will not match anything while Control-Shift-X will. The latter is equivalent to Control-X, since you will only get X (not x) by pressing Shift. - Withdrawn windows completely disappear, ie. from the task list. - Stippling works (apart from stippled ARCs, which don't get stippled in the Windows port either). - Windows port did not look at GC values for CapStyle, JoinStyle, LineStyle. This port does. - Lines have (specified) width. This needs the "geometric line width" in OS/2, which is only used by GpiStrokePath (and GpiModifyPath), so use that. - Ctrl-X and the likes work. - Focus problem after grab fixed. I was too correct in following the "Results" section for XGrabPointer, which says to return AlreadyGrabbed if the grab didn't succeed. This should be ignored, like in the Windows version, and GrabSuccess should always be returned. (Font patch by Ilya Zakharevich assimilated) - Fonts (sigh ;-}): calculation of size was wrong. Furthermore, because of unclear / confusing GPI programming info, the check of the sizes of the available fonts wasn't done on the right value. It turns out you have to *request* the size via the lMaxBaselineExt member, while the actually used value is in lEmHeight. Am I dense or what?? Actually, the returned nominal pointsize is OK. Compile-time option (via #define) provided for ignoring a PM-provided font resolution of 120dpi, taking 96dpi instead, which is the resolution in VGA and upto ?800x600?; requested by Ilya Zakharevich. - Color images now work, including those that get split up into several before drawing (LCOLF_RGB instead of LCOLF_CONSECRGB in GpiCreateLogColorTable; LCOLF_CONSECRGB should (only) be used with Palette Manager). - Width calculation of fonts improved by using TXTBOX_BOTTOMRIGHT instead of TXTBOX_CONCAT. - Tcl: File globbing was broken because DosQueryPathInfo doesn't like ".\" for the file/directory argument. Similarly, directories weren't seen. - "option readfile" wasn't succesful with OS/2 files, but was with an .Xdefaults copied from Linux. Choked on the Return&Newline being replaced by just the Newline, yielding a "nr.of chars read" smaller than the file size, aborting the entire process. Fix necessitated changing the generic file tkOption.c, function ReadOptionFile with the corresponding (fixed) code of Tk 4.2. - Compile time option (set in makefile.emx) to use "9.WarpSans" as default font. Beta 4 ------ - A "wm withdraw" now also works when running or sourcing a script (i.e. mapping/creating in withdrawn state). Switching to a withdrawn window (eg. by using the task list) works okay. Previously only a "wm deiconify" would do the trick of exposing the client area (restoring contents). - Resizing in vertical direction fixed. When resizing to a smaller height with a menu bar involved, the menu bar disappeared (partly or entirely, depending on the size). Cause was the use of CS_SIZEREDRAW for child windows. - The default screen name is determined from the DISPLAY environment variable, if available, so scripts asking for toplevels with -screen <name> don't abort (and any toplevels without specifying a screen in an invocation of wish with the -screen <name> argument). - Double-clicking now works correctly, OS/2 PM's WM_BUTTONxDBLCLK messages get changed to both a ButtonDown and a ButtonUp event. - Fonts changed again. Presentation Parameter-style specification now fully supported: PointSize.FontName[.Attribute][.Attribute]... where Attribute is one of bold, italic, outline, strikeout, underline. Some fonts (eg. -*-Helvetica-Bold-R-Normal-*-240-*-*-*-*-*-*) didn't show up. This was because they were scaled to pointsize 0 because the 240 is in the "pixels" spot, which should be a substitute for the point size (or at least was in the Windows version), but wasn't implemented identically. An explicit point size will override it. The ascenders and descenders of scalable fonts are fixed, so they won't get progressively larger when enlarging the font. - Double ckfree because of WM_DESTROY message (caused by WinDestroyWindow in XDestroyWindow, tkOS2Window.c) fixed, care of sleuthing by Ilya Zakharevich. - Resizing works, wm minsize and wm maxsize likewise. Beta 3 ------ - Merged resources for additional pointers into the DLL. - Clicking in the console gets the focus now too (previously, only clicking the titlebar worked). - Fonts work a little bit more correct. ;-) Height, width and actually used pointsize are correct now. Without special handling, every scalable font is of point size 12! Code by Ilya Zakharevich (ilya@math.ohio-state.edu) incorporated into tkOS2Font.c, enabling the use of e.g. "10.Courier". - Images work. Funnily, they are (exquisite) greyscale on a 64K display but color on a 256 palette management. The OS/2 part is doing what Tk tells it to with regard to color though, it just gets handed grey values, so I have to assume it is working as advertised. - 'exec' was broken in Beta 2. Fixed. PM apps should be exec-ed with '&' unless they are very short-lived. Tclsh will be "listening" for output from the app and this will "lock up the queue" because of the single-threadedness. - The format of $tcl_platform(os) has been modified slightly; return values are now "Warp 3" and "Warp 4" instead of "Warp v3" and "Warp 4 (Merlin)". Other values: platform "OS/2", osVersion e.g. "4.0", machine "intel". - Temporary files are cleaned up when closed by specifying a DosClose wrapper to be called on file closure. - Humongous memory leak in TkOS2SelectPalette fixed. Beta 2 ------ - Font selection works correctly now, so that any font available through the font dialog is available. It first determines all fonts in the system (#ifdef DEBUG) / all fonts with the specified facename (#ifndef DEBUG) via GpiQueryFonts and then determines the most suitable font based on the size. Preference is given to bitmap fonts over outline (scalable) fonts for purposes of performance in using the font. When many fonts of the same facename exist, the scalable one is at the start of the "list" and the correctly sized bitmap font is at the end of the "list", this may exact a performance penalty at the time of determining the font. This is a small one-time penalty though. Fonts with a '-' in their name have to be specified by length-3-array (eg. "Conga-Normal 180 normal"). To not get stuck with a default font (ie Courier), you will need to use font names that OS/2 knows *and* use the right case: helvetica -> Helvetica or Helv Times -> Times New Roman or Tms Rmn (eg: ... -font "-Adobe-Times New Roman-medium-r-normal-*-180-*-*-*-*-*-*" ) - Colors on non-Palette management system work. Not tested on VGA but you will not get any better there... - Choosing "Close" (Alt-F4) on a torn-off menu or otherwise non-"main" window will only close that particular window, not the whole application. Beta 1 ------ No record has been maintained for bugfixes previous to this. THANKS TO ========= - Ilya Zakharevich for his critical testing. - Anna Chiara Bellini for putting an FTP server at my disposal. - Anyone not named that has assisted by beta testing and/or doing suggestions. BUGS ==== TO DO (?) (Extending port) ========================== - Have Shift-Insert, Shift-Delete and Ctrl-Insert act on clipboard. This means extending the "Tk Clipboard" only approach to use PRIMARY and/or SECONDARY too. Just replacing CLIPBOARD with PRIMARY has Shift-Insert working. - Global Grab doesn't turn pointer into clock outside of dialog. Possible?? - Make button 2 and 3 of the mouse switchable. To OS/2, button 2 is the right mouse button and generates a WM_BUTTON2* message, 3 is an optional middle mouse button (WM_BUTTON3*). For X, and thus XFree86 in an OS/2 Full Screen session, button 2 is the ("always available") middle button and 3 the right. - Implement a "send", either via DDE or via Pipes/Queues? - Multithreading (dual-threading: one extra thread for the message queue to stay responding to the system, coomunicating with the one that now exists which might be computing for a longer time). - The list of occupied logical font IDs is a straight array. This method will leave "holes" when freeing another font than the last one. Solution: convert to a linked list or use Tcl's hash table mechanism.

The domain http://www.vaeshiep.demon.nl/ is defunct since 2007. I had to switch to Windows with that move so I had to abandon the OS/2 port of Tcl/Tk.
