You are just missing the
_DEFS(gstreamermm,gst)
line in the .hg file.

Hand-writing signal wrappers is unpleasant. I would use gmmproc where possible.

Time is running out. There's a slim chance that this could be considered before
the API freeze if you could reply.

------- Comment #10 from Murray Cumming  2009-03-04 23:16 UTC -------
So, if I understand it, this is based on these ideas:

1.
You know what slot (signal handler) type to expect for the specified signal, by
using the sigc::slot<>::SlotType tyepdef. The dynamic_cast<> checks that it's
the correct slot type. For instance:

void connect(T_sig sig, const Glib::ustring& name)
{
  sig.connect(get_slot<typename T_sig::SlotType>(name));
}

That's nice.

2.
You can't connect to any signal. Your libglademm hard-codes checks for each
signal for each widget, so it can have the specific signal accessor (and type
information) to call connect() in 1.

That doesn't seem acceptable. I can't imagine how we would document its
limitations without including a big ugly list of signals.

3.
You have to parse the glade XML file because libglade doesn't give you any API
to get these signal handler names (and their widgets) for you. That's
unacceptable, but maybe you can check if GtkBuilder (which replaces libglade)
has API for it, and maybe you could request that if necessary.


By the way, this patch would be more readable if it did not use macros.
