Not sure it's better (actually I just took a small glance at the link),
but there are other solutions.
First, the one used by gconf-editor [1], that consist of a custom cell
renderer that provides the appropriate editable depending on the type of
the value it holds. This is not necessarily the easier way, but it's
quite interesting IMHO.
The other solution I know is to pack all CellRenderer that might be used
for editing, and only make one visible/sensitive, depending on the row's
value type. This is what we current use in the implementation of
Geany's stash editor [2], [3].
IMHO the second solution is the easier one, nut sure it's the bast
though. Hope it helps.
