Tcl/Tk Extensions for Windows

Applications developers working the Tcl/Tk programming language under the Microsoft Windows operating system environment can find a number of extensions for the latest, stubs enabled, versions of Tcl/Tk 8.x

• The DDE 2.0 package provides a comprehensive DDEML interface to Tcl/Tk using a persistent connection model. This package allows rapid development of DDE servers entirely in Tcl/Tk.
• The Animate 1.0 package is an extension that aids the development of image animation applications. Frame rates suitable for scientific animations can be achieved using native Windows format images.
• The Sound 1.0 package is a very basic extension to Tcl/Tk that allows the playing of .WAV format files. This package is useful for simple sound annotation of Tcl/Tk applications.
• The TkPrint 1.1 package is an enhanced version of the TkPrint extension. The package permits the capture of widget windows to local files, and the printing to local printers of displayed widget contents using the native Windows printing facilities.
• The Image 1.2 package is a Tcl extension that is useful for doing image processing on images in indexed color formats, such as the BMP format. This package enables the construction of image processing pipelines in Tcl that can perform a variety of functions.
• The Help 2.0 package is an extension to Tcl that provides an interface to Window help system database files. Using this extension Tcl scripts can implement access to help topics in standard Help files.
• The Containers 1.2 package is an extension to Tcl that provides a number of commands that implement container objects. The bag, stack, queue, tree, priority queue and the random queue are implemented.
• The Tcl Fltk 0.4 package is an extension to Tcl/Tk that implements a binding to widgets supported by the Fast Light Toolkit.

Application developers using Tcl/Tk under the Linux operating system on INTEL hardware can find the following extensions at this site. These extensions are supplied as binary shared libraries in ELF format for use with Linux 2.0 and later releases.

• The GDBM 0.6 package is an enhanced version of the earlier GDBM 0.4 package for Tcl. This package provides an interface to the GNU version of the DBM database file system. Added features include basic record encryption and both key and record string searching.
• The Image 1.2 package is a Tcl extension that is useful for doing image processing on images in indexed colour formats, such as the BMP format. This package enables the construction of image processing pipelines in Tcl that can perform a variety of functions.
• The Containers 1.2 package is an extension to Tcl that provides a number of commands that implement container objects. The bag, stack, queue, tree, priority queue and random queue are implemented.
• The Tcl Fltk 0.4 package is an extension to Tcl/Tk that implements a binding to widgets supported by the Fast Light Toolkit.

Application Developers that use Borland (Inprise) development tools can find pre-compiled binaries of the Tcl/Tk 8.2.x stub libraries on this site. These libraries are needed to replace the standard libraries shipped with the binary releases which are useful to users of Microsoft development tools. These stub libraries work just fine with BC++ 4.5, BC++ 5.0 and BC++ 5.5 compilers.

Tcl Scripts

These are demonstration scripts that are of interest to Tcl/Tk users who are interested in meteorology. They make use of the extension packages that can also be found on this site.

• WXMAP.BAT is a script that will acquire a plotted, analysed surface chart from the Canadian Meteorological Centre and make it your wall paper. You can set it up to run at timed intervals using the Windows Task Scheduler, of with the WinCron application available on this site.

These applications are of use within Tcl scripts and perform functions that are not native to Tcl.

• setroot.exe is a Windows 9x/NT application that will set the wallpaper file. This program is similar to the UNIX xsetroot application.
• WinCron 1.0 is a clone of the popular UNIX cron application. WinCron is a replacement for the Windows Task Scheduler application. WinCron includes a DDE interface that allows it to be controlled by Tcl scripts.
• grab.exe is a program for Windows 9x/NT that can be used to capture images of displayed windows and their child windows to the clipboard or a file. This program is adapted for use within Tcl scripts.
• utils.zip is a small set of utility packages used by some of my scripts. It has a HTTP based file down load code and some convenient procedures for testing things. This is the TclUtils package. Linux users should remember to unzip this archive with the -L option.
