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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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

Even a widget as simple as a label has some 20 different settings (also known as properties) that can affect its look and feel. Typically, the author of a Tk program will alter a minimum of these, as all resources have a default or "fallback" value. Users can override fallbacks through general setting files, and through files that include settings for specific applications. Programmers can give users the option of loading sets of resources from file as well. Resource setting is useful for applications which may be used by people with poor sight or who are colour blind, and also for giving a consistent look and feel to a group of related windows or applications.
