title: How to render Gtk.DrawingArea() in a Gtk.Treeview()?
body: <p>I'm having some problems to render a <code>Gtk.DrawingArea()</code> in to a <code>Gtk.TreeView()</code>. Is this possible?</p>
  
  <p>So far I have this code:</p>
  
  <pre><code>window = Gtk.Window()
  window.connect("destroy", lambda q: Gtk.main_quit())
  
  darea=Gtk.DrawingArea()
  darea.modify_bg(Gtk.StateFlags.NORMAL, Gdk.Color(1,1,1))
  
  liststore = Gtk.ListStore(Gtk.DrawingArea)
  liststore.append([darea])
  liststore.append([darea])
  treeview = Gtk.TreeView(model=liststore)
  window.add(treeview)
  
  treeviewcolumn = Gtk.TreeViewColumn("Drawing Areas")
  treeview.append_column(treeviewcolumn)
  
  cellrenderer = Gtk.CellRendererPixbuf() #Gtk.Drawable() #Gtk.CellRendererText()
  treeviewcolumn.pack_start(cellrenderer, True)
  treeviewcolumn.add_attribute(cellrenderer, "d areas", 0)
  
  window.show_all()
  
  Gtk.main()
  </code></pre>
  
  <p>But ofcourse it doesn't works because I'm trying to render it with a <code>Gtk.CellRendererPixbuf()</code>. Is there any kind of<code>Gtk.CellRendererDrawingArea()</code> ?</p>
