Thats the traditional solution, but from a UI design perspective I've never
really been happy with it. I saw dials implemented on an SGI once and
thought that was a pretty good idea, since end users are familiar with them
in the "real world". The problem remains how you make a dial context
sensitive, where its range is variable depending on other configurations.
BTW, does GNOME have a dial widget? I don't think GTK does, but maybe I've
just not heard anyone talk about it.

In this case (although I've forgotten the specific case we're talking
about) the range is defined, but varies according to the resolution
setting. So its a question of whether this is considered "well defined" or
not. To me, it is well defined. The input mechanism doesn't need to
change, but the range allowed does. However, you do have the problem of
added precision when the range changes from a 72DPI context to a 300DPI

You guys crack me up. :-)
