 ==== Motion hints ====
-According to the laconic [[file:///usr/share/gtk-doc/html/pygtk/class-gdkevent.html#description-gdkevent|official documentation]] and on the [[http://www.pygtk.org/pygtk2tutorial/sec-EventHandling.html|tutorial]], the goal of gtk.gdk.POINTER_MOTION_HINT_MASK is to send you a motion event and then not send another until you call mywidget.get_pointer(), so that events don't keep queuing waiting for you to handle them.

+        GtkTreeView::expander-size = 30
+    }
+    class "GtkTreeView" style "expander-big"
