Re: Getting type/arg info without running a GUI?

[Lauris Kaplinski <lauris helixcode com>]

You should call gtk_object_get_type () and gtk_window_get_type (),
before
you can use corresponding gtk_type_from_name ()

The idea is, that in first invocation gtk_xxx_get_type () initializes
corresponding type class, including registering its name, and only after
that you can query that class by its name.
