well, it should work, but I don' think it's the best way, since this
will duplicate data in memory, and
make very difficult the synchronization of all the widgets.

you should be using Gda_ConnectionPool's, which do exactly this. The
Gda_ConnectionPool object is
a bit incomplete, so please comment on what you think it's missing, and
I'll add it.
I think that's the best way, so that all widgets share the same
connections, and get proper notifications all of them at the same time
(for example, if you close the database, all widgets connected to that
database could get a notification so that they refresh themselves).
