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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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

Posted by samblake (samblake), 7 December 2003
Hey, can someone tell me how to make a button in tcl/tk with a bitmap on it that changes to another bitmap when clicked and then changes back when the mouse button is released. Thanks.

-Sam

You'll need to bind the ButtonPress and ButtonRelease methods on the button to configure the button to change the bitmap. Something like:

Code:
bind .sample ButtonPress {
           .sample configure bitmap xxxxx}
bind .sample ButtonRelease {
           .sample configure bitmap yyyyy}


I don't have Tk running on the machine I'm posting from, so the syntax above may not be 100% perfect - but it should point you in the right direction
