Re: libseed-list seed - GVariant /GDBus

["Alan Knowles" <alan akbkhome com>]

This should get you going there.

http://www.roojs.org/seed/gir-1.2-gtk-2.0/seed/GLib.Variant.html

Looking at the introspection for the array, It does not look like it will work at present

The introspection gir looks like [below]. - the second parameter should be an array (however it's not picked up at present)

The fix will be adding a section to 

gobject-introspection/gir/glib-2.0.c 

something like this.
/**
 * g_variant_new_array:
 * @child_type:
 * @children: (array length=n_children) (element-type GVariantType*):
 */

Then rebuilding gobject-introspection, and hence the Glib gir.

Once you have it working file a bug against gobject-introspection (it's a subproject of glib) with the patch

Alan
