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

[Jeremy Dinsel <jeremy gunix net>]

I can't seem to find out how to use this widget after reading all the
docs that I can find. Any assistance would be appreciated.

If I'm going the following:

// Create
this->transaction_log_file = manage(new class Gnome::FileEntry());

...

// Read from in a callback
pbox->transaction_log_file->get_full_path(true);


... and the value that the user supplied is either NULL or does not match
what the method expects (a directory when looking for a file, for
example), how can I prevent the routine from crashing? It returns an
improperly formed STL String class. Is there a way that I can get the
entry from the Gnome::FileEntry without using the get_full_path() method
-- similar to Gtk::Entry's or Gtk::SpinButton's get_text()? Gnome::Entry
is a mystery, too.

If anyone would like to comment on adding history to the selected values
of Gnome::FileEntry and Gnome::Entry, I'd appreciate that, too.

I've been reading documents here:

http://gtkmm.sourceforge.net/gtkmm2/
http://david.hedbor.org/pikeman/pigtk/

There don't seem to be many example Gnome::FileEntry programs available,
either. I've tried downloading code form sourceforge or items linked off
of the gnome.org page and reading the code, but haven't had success
there either.

Thanks,
