Hi there,

if I'm not completely mistaken here, this has nothing to do with glade.
The thing just is, that you need to return to the main loop from the
callback for the widgets to be drawn properly. 
That is prolly why you put in your gtk_main_iteration though I doubt
there is a guaranteed way to make this work.

So the complicated version would probably involve having hooking up a
callback to the configure event for the second window that starts smth.
and then automatically deregisters itself after the first run.

The other thing I've found to work is use a GTK_DIALOG rather than a
generic window and then do smth. along the lines of:

    result = gtk_dialog_run (GTK_DIALOG (dialog));

    if (result == GTK_RESPONSE_OK) {
        got_file_name =
            gtk_file_chooser_get_filename (GTK_FILE_CHOOSER (dialog));

        xml = NULL;
        xml = glade_get_widget_tree (GTK_WIDGET (xvc_pref_main_window));
        g_assert (xml);

        w = NULL;
        w = glade_xml_get_widget (xml, "xvc_pref_sf_filename_entry");
        g_assert (w);

        gtk_entry_set_text (GTK_ENTRY (w), strdup (got_file_name));
    }

    gtk_widget_destroy (dialog);

Of course, if you're not really interested in the user's input you can
just ignore the result.

HTH,

Karl.
