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.
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.

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

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
