Re: [GObject Introspection] Getting style colors using GTK and Python

[John Palmieri <johnp redhat com>]

I talked to Colin.  Current plans are that PyGI will only be fully supported on Gtk3 where Gdk style functionality is going away.  See http://blogs.gnome.org/carlosg/2010/08/23/css-like-styling-for-gtk/ for an idea of where the styling code is headed.  Supporting arbitrary C structs won't be fixed and there are plans to prevent access to these potential segfault prone constructs.
