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. > If you do not have a well-defined range, you should use a plain > entry.

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 context. > X-Tigert-Header: Eek! > X-perience: what you needed right before obtaining it You guys crack me up. :-) -- Michael J.
