- dialogs, where two widgets (typically GtkTreeViews) contain a list
- of variables, and the variables may be selected by the user and
- transfered to between the widgets, in preparation for some
- operation.
-
- Currently it assumes that the first widget is GtkTreeView and the
- second is a GtkEntry (as required for the Weight Cases dialog).
- It needs to be generalized further to make it useful.
