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

[Julian Missig <julian jabber org>]

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.

With gnomemm2, a Gnome::UI::FileEntry has a gtk_entry() accessor 
directly, so the same call would work.

It would of course be better if this problem were fixed on gnomemm's 
side, but for the time being you can do things like check for a length 
greater than 0 and use things like g_file_exists (g_file_test(str, 
G_FILE_TEST_EXISTS) in glib2) to make sure the path is decent before 
getting it.
