this looks pretty interesting in a number of ways. i would be quite
interesting in merging this code with a Gtk-- object that I have
called a Gtkmmext::MotionFeedback. Its a lot more general than a knob,
and has a number of nice features that yours does not (such as the use
of shaped windows). It can then be used as a slider, a knob or others
kinds of control widgets where mouse motion is used to control an
adjustment in combination with widgets.

i'll see what i can do. i try to stay away from GTK+ widget creation
when i can, because its so painful compared to doing it in C++, but
now that you've offered up the framework, perhaps i can get around to
this :)
