Scott already created a class "SideBar.vala", which can be found here:
http://bazaar.launchpad.net/~beatbox-team/beat-box/trunk/view/head:/src/Widgets/SideBar.vala
That class draws the triangles (expanders) on the right. We have to create our own instance, and add the Gtk.TreeView (tree_view) to it.
On Beat-Box they also use their custom Tree View, this might also be useful:
