Re: libseed-list GTK+3 example?

["Alan Knowles" <alan akbkhome com>]

Gtk3 docs have been generated now, 

At the bottom of my rant about unity, there are some details on the major changes in Gtk3 that affect seed.
http://roojs.com/index.php/View/236/.html

In this case,
http://www.roojs.com/seed/gir-1.2-gtk-3.0/seed/Gtk.DrawingArea.html

The signal signature is this,
draw (Widget self, Context cr) : gboolean
function draw_arc(ctx,cr){
	print(cr); // should output [object CairoContext]
}
