3 * This code renders the Gtk tree into a set of Gtk elements.
4 * principle = one NodeToGtk wraps around the original 'node'
6 * it's called by the view element with
7 * var x = new JsRender.NodeToGtk(file.tree);
8 var obj = x.munge() as Gtk.Widget;
12 * The idea behind the Javascript tools stuff is that we can
13 * transform what is actually being requested to be rendered
14 * -- eg. an AboutBox, and turn that into load of real widgets..
15 * that could be displayed..
17 * we could go on the theory that we send the whole tree to the 'plugin'
18 * and that would do all the transformations before rendering..
19 * -- this would make more sense...
20 * -- otherwise we would call it on each element, and might get really confused
