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

[Jeremy Dinsel <jeremy gunix net>]

Thanks for the reply, Julian. However, with the supplied code, I am
still getting errors:

printf("trans_log_file: %s\n",
   pbox->transaction_log_file->gtk_entry().get_text());

results in:

propertybox.cc: In method `void Gtivo_Prefs::Set_Configuration(propertybox *)':
propertybox.cc:500: request for member `get_text' in `pbox->propertybox::transaction_log_file->Gnome::FileEntry::gtk_entry()', which is of non-aggregate type `Gtk::Widget *'

:  From the Gnome::FileEntry object you can call
: fentry->gtk_entry().get_text() -- since a Gnome::FileEntry is a
: Gnome::Entry, which has the gtk_entry() accessor.

: G_FILE_TEST_EXISTS) in glib2) to make sure the path is decent before
