Re: [Vala] How to implement the get_type method of Gst.URIHandler interface in vala?

[Lei Miao <leimiao09 gmail com>]

Adding the CCode to the vala code solved the problem. Thank you!

I generated two bug reports for this discussion: *Bug
726744*<https://bugzilla.gnome.org/show_bug.cgi?id=726744>and
*Bug 726745* <https://bugzilla.gnome.org/show_bug.cgi?id=726745> .
