Shaped and managed tk toplevels

Here is a starkit with sources included for creating non-rectangular toplevels in tk, but allowing the window manager see (manage) your window as well. The alternative, to use the shape extension and "wm overrideredirect" is not very friendly. If you are going to write something like Xmms in tk, this is the ultimate solution of your problems. You only need to have a image supported by tk or the Img extension, with transparent areas as required. It is not needed to create any other bitmap, as the command "setXwinshape" will extract the mask for you and use it to set the shape. Yes, it is really simple!

Microterminal

Here is a design of a somewhat complex Altera FPGA, that we used to manufacture some years ago. The last revision was made in 1995 and you will need Altera Corporation software to compile it, because it is written in AHDL (not the same as VHDL). But if you are curious to find out how a FPGA is defined for a not so trivial design, study this code. You may find the results of the compilation in the *.rpt file, the sources are the *.tdf files. At last, pleeeease don't ask me to resurrect this design again. I will not do the same as it happened with TinyCobol :-) Never more! Simply, I have no time.

You can also find here (front) and here (back) pictures of the manufactured device based on this FPGA.

Webmail

Take this little webmail program to serve your customers, if you're a internet service provider, or even if you prefer to use your browser to read all your mails. It's a good way to learn the principles of web programming with tcl/tk. There is a script (in tcl, of course!) to install, but some setup info must be edited on the main script (webmail). It will be installed in your apache cgi-bin and will create a cgi-bin/html directory.

LsBrowse

This little utility is useful if you catalog your cdroms or backups with the well known ls -lR /cdrom | gzip >catalog.gz
Is very annoying to look at the unstructured text of such catalogs, but not with this tiny program. There is no manpage: just enter the catalog name (that must be gzipped), or choose with the file button, then press browse. To look at the contents of a directory, just click on it at the left hierbox. To expand directory hierachies, double click or click at the "+" symbol. Well, you know the remaining operations...

To run lsbrowse (2 Kbytes), you will need tcl/tk 8.0 or newer and BLT, a nice tcl/tk extension.

Gscan

Driver for the KeenView

Quadronegro

A client/server teaching tool with a blackboard, irc-like chat, and a remote-execution tcl/tk facility. The latest version is quadronegro-0.0.3.tar.gz. You need tcl-dp and tcl/tk8.0 or better.

pppliga.tcl

This is a tiny script in tcl for ppp configuration and connection. Just make it executable (chmod +x) and don't forget to fill all fields, or it will not work.
You can have some clues by looking at the source ( use the source, Luke :)
