[WJG] (19/05/09) The 2.10 release of [Gtk] saw the introduction of a number of new [widget]s and features into the core widget set. One of these is a preplacement for the deprecated GnomeDruid. The assistant widget allows the programmer to guide a user through a number of interactive steps in order to determine an outcome. Whilst at the time of writing this widget is still pre-release, here's a glimpse of the [gnocl]::assistant test script and how it can be used. As always, comments and feedback always welcome.
