Gtk::MozEmbed - how to submit forms on pages rendered with it?

[Vlad Harchev <hvv hippo ru>]

 Hi,

 I desperately need to be able to submit forms on pages rendered with
Gtk::MozEmbed. Is there any information on how to do it? It it sufficient
to make hooks to some combination of signals (with proper return values) or
it will require extending XS code?

 Please reply if you know anything on this topic.

 Thanks in advance!

 Best regards,
