| For 2023 (and 2024 ...) - 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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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)) |

A new Tcl/tk example - a window to show system status  From today's Tcl course - where we have also added a GUI on the front using Tk to give a window in which we display system information.The code is divided into a number of sections 1. Definition of pieces of code to be run in the event of a button being pushed, or some other action 2. Creation of the widgets (components) to be shown 3. Packing those components into a geometry 4. Processing the event code initially (to pretend that initial buttons had been pressed) 5. Finally, the code enters a main loop to wait for events and process them as it receives them. Source code [here].
