Hi David, I wrote a widget for OpenMoko that replaces GtkScrolledWindow, with very similar API, that allows you to do finger-scrolling instead of scroll-bar scrolling - The SVN repository is at http://svn.openmoko.org/trunk/src/target/OM-2007.2/libraries/libmokoui2/ and you can find debian packaging at https://edge.launchpad.net/~cwiiis/+archive , although I'll warn you that that's a bit out of date and I think the Intel MID project have more recent packaging (they have collaborated with me and kept me informed on this, it's my fault that my own packaging is out-of-date).
There are caveats with using this widget, as the GTK event system wasn't really designed with this interaction in mind. The widget works by intercepting mouse events and re-synthesising new events for the underlying widgets - This usually works fine, but certain things don't work, such as mouse-over (this is easy to fix, but was unnecessary given it's aimed at touch-screens) and double-clicking (harder to fix). You might also have some fun problems if you grab the cursor too. Hope that helps some - depending on your users, you may find that it's more efficient to write your own custom-purpose finger-scrolling widget. If you find that and you want some code to use as an example (and you don't find any better code than mine (which I'm sure there's a lot of ;)), I'd recommend you take a look at the finger-scrolling widget I've written for tidy - http://svn.o-hand.com/repos/tidy/trunk/tidy/tidy-finger-scroll.c - The code is much cleaner as clutter has a more advanced events system and I wrote it after having learnt a lot with MokoFingerScroll.
