Re: [gnomemm] Gnome::FileEntry -- get_full_path causes crash

[Jeremy Dinsel <jeremy gunix net>]

I ended up wrapping things like so:

        Gtk::Entry *g-entry;
        g-entry =  (Gtk::Entry*)pbox->transaction_log_file->gtk_entry();

        Stuff = g-entry->get_text();
        printf("trans_log_file: %s\n",Stuff.data());

It returns the string that I had entered. My method seems kind of
hookie.
