You probably don't want to use setVisible. It's used in relation to having
Setting objects around to manipulate the database but without the
assocaited UI. setEnabled should be the way to go, although it may not be
fully implemented on all UI objects. (it's used quite a bit within the
videosource.* stuff and it was also used within the channel editor,
The way I got around this kind of thing before was by using a
TriggeredConfigurationGroup (also see videosource.* and scanwizardhelpers.*)
AFIAK it's hard to do this neatly any other way.
