------- Comment #12 from Paul Pogonyshev  2007-02-16 23:25 UTC -------
I also took the latest version of the files from my program.  No idea if they
differ from what I posted before.

A nice idea that would make usage simpler is to implement something like
C-level function gtk_binding_set_by_class ().  So, user-derived classes
wouldn't have to define specific on_key_press/on_key_release handlers, but just
add bindings to result of Gtk::BindingSet <...>::by_class().  Then all Gtkmm
classes would call by_class() itself in default handlers and if it returns an
existing object, would call activate_event() on it.  I'm not sure if that is
difficult to implement, but since it requires changing existing Gtkmm code, I
don't volunteer.

Make Glib::Value<> register custom types dynamically

I had a go at this and changed the Glib::Value<> implementation to register
custom types dynamically, using a custom GTypeModule.  Unfortunately, I hit a
bug in GLib (#409043) which prevents this from working.  The non-working patch
is attached for reference.

The fix plus some cleanup

Here's the patch.  It turns out that a TypeTraits<bool> specialization is in
fact necessary, though of course it has to look quite different:

template <>
struct TypeTraits<bool>
{
  typedef bool     CppType;
  typedef gboolean CType;
  typedef gboolean CTypeNonConst;

  static CType   to_c_type      (CppType item) { return
static_cast<CType>(item); }
  static CType   to_c_type      (CType   item) { return item; }
  static CppType to_cpp_type    (CType   item) { return (item != 0); }
  static void    release_c_type (CType) {}
};

Essentially a bunch of no-ops, and no pointers appearing out of nowhere
anymore.  The patch also includes some moderate cleanup of keyfile.ccg. 
Unfortunately, I noticed another API bug:

  void set_boolean_list(const Glib::ustring& group_name,
                        const Glib::ustring& key,
                        Glib::ArrayHandle<bool>& list);

  void set_integer_list(const Glib::ustring& group_name,
                        const Glib::ustring& key,
                        Glib::ArrayHandle<int>& list);

The 'list' parameters should obviously be 'const' here.  The patch makes them
const, though of course doing so breaks the ABI.  However, I'd argue that this
is in fact an ABI fix and not an ABI break.  Our documented policy is that the
various *Handle<> types should never be instantiated directly in user code.  If
you follow that rule, using set_boolean_list() and set_integer_list() becomes
impossible without the 'const'.  Also, set_boolean_list() was broken anyway to
begin with.

It is possible to leave the old methods with the non-const parameters in the
library, and enclose them within #ifndef GLIBMM_DISABLE_DEPRECATED conditions
in the header file.  But given the overall brokenness of the array interface
before this patch, I'm not sure it's actually worth the hassle.

------- Comment #3 from Murray Cumming  2007-02-17 23:07 UTC -------
I know it's tedious, but I think we need to prove (with a test) that each
existing method cannot work, and therefore cannot be in use, before we change
it. At least the test will prove that this does work.
