I decided to also post them to a github repo in the end.. (backups are always good).

git clone https://harryhaaren@github.com/harryhaaren/Gtkmm-Custom-Widgets.git

should give you a folder called Gtkmm-Custom-Widgets in your ~/

Cheers, -Harry

PS: I have at least one more widget to add in there, and probably more from various little
other projects I have here... will probably be done in the next few days. (They'll need some
small changes to compile without OSC libraries etc..)
