One more thing.
I get my widgets as follows and all the name's are 0x0.
if(!gtk_builder_add_from_file(builder, filename, &error)) {
g_warning("Couldn't load builder file: %s", error->message);
g_error_free(error);
}
gtk_builder_connect_signals(builder, NULL);
w=GTK_WIDGET(gtk_builder_get_object(builder, "rxNb"));
All w->name's are 0x0. This never use to be the case. So this seems to
be the root of the problem. Is this a bug in Gtk Builder?
Thanks,
dhk
