[Gtk-sharp-list] Gtk.Timeout parameters

[Jonathan Pryor]

No.  ``CheckButton()'' is a function invocation, not a delegate creation
expression, and thus will not work either.

It should be noted that the next version of C# (v2) will support the
implicit conversion from a function into a delegate type.  This would
allow the original code to work:

	Gtk.Timeout.Add (2000, CheckButton);

As the C# compiler could infer the appropriate delegate type, and ensure
that CheckButton has the appropriate signature.

But that's for v2 (as part of the anonymous methods extension), not now.
