For 2023 - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.
Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!
I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Using Tcl/Tk resource files for flexible applications
If you're looking to write a Tcl/Tk application that can be flexibly configured, don't forget to use named resources. Here are two displays from the same program:

1. I drew the buttons WITHOUT ANY TEXT AT ALL, and I did NOT specify a background colour either.
2. I specified an option readfile
in my code to bring in a file of resources ... to complete those definitions.
3. I actually created the resource file .... which is simply edited when I want to make changes, but don't want to pay for the expense of getting my program changed!
Here's the resource file - for the Orange, White Hill, Hastings example ...
