  2. It’s planned to port this great component to Gtk 3 and Goocanvas?, i forked via github and i’m trying to port it to these frameworks but has some issues because are Gnomecanvas an Goocanvas are very different, in things like classes and names.


  3. Hi. It seems I need libgvc to install this, but after crawling the web for an hour I haven’t managed to find the source code. Any links to source greatly appreciated. Note that I need source, not an RPM or similar package.
