you should call the gda_server_error_make, which in turn adds the error
to the list of errors for that connection, and then, this list is sent
to the client, so you don't have to deal with the dialog box directly.
This is done in the client-ui library.

yes, that was the idea on making the Gda_ServerImpl a GtkObject. We can
use callbacks for some things, but I don't understand very well what you
mean.

You must pass a valid Gda_ServerError object to the
gda_server_error_make function. If not, it will cowardly return from the
function.

Stephan? are you here?

you must first contribute with code. As soon as you do so, I'll ask for
one for you
