For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
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:

So - how did I get the difference in colour and text labels?

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 ...

*top.text: White Hill
*bottom.text: Hastings
*background: Orange
