  and there are some examples, but documentation is sorely lacking.

  but it's pretty simple if you are used to glade; you just give the
signal handler as "erl". when the signal is triggered the erlang process
will receive a message. the widgets are represented as erlang processes
with registered names (in the c-node), so you send GTK primitives as
messages.

 the code is here;
