[gtkmm] Gtk::Main::input gone?

[Eric Bourque <ericb computer org>]

I'm in the process of converting my gtkmm app to gtkmm2 and immediately
noticed that Gtk::Main::input doesn't seem to exist despite being
documented in the new manual:

http://gtkmm.sourceforge.net/gtkmm2/docs/tutorial/html/ch17s02.html

What is the current method for having a method called based on activity
on a file descriptor?

I used to use:

Gtk::Connection
connection=Gtk::Main::input.connect(SigC::slot(this,&object::received_handler),
					       file_descriptor,
					       GDK_INPUT_READ);

Any help is greatly appreciated.

Cheers,

Eric
