+=== Sugar toolbar version ===
+Sugar toolbars changed in Sucrose v0.86. You can detect which version you are running by checking for an ImportError:
+ try: # 0.86 toolbar widgets
+     from sugar.bundle.activitybundle import ActivityBundle
+     from sugar.activity.widgets import ActivityToolbarButton
+     from sugar.activity.widgets import StopButton
+     from sugar.graphics.toolbarbox import ToolbarBox
+     from sugar.graphics.toolbarbox import ToolbarButton
+     _new_sugar_system = True
+ except ImportError:
+     _new_sugar_system = False
+Use the flag to determine whether to create old-style or new toolbars:
+ if _new_sugar_system:
+     # Use 0.86+ toolbar design
+     toolbar_box = ToolbarBox()
+     ...
+ else:
+     # Use pre-0.86 toolbar design
+     self.toolbox = activity.ActivityToolbox(self)
+     ...
+You can share callbacks between versions, but take care to make sure you are using the proper context:
+ # 0.86+
+ fullscreen_button.connect('clicked', self._do_fullscreen_cb)
+or
+ # pre-0.86
+ self.viewToolbar = ViewToolbar(self)
+ class ViewToolbar(gtk.Toolbar):
+     def __init__(self, pc):
+         self.activity = pc
+         self.activity.fullscreen_button.connect('clicked', self.activity._do_fullscreen_cb)
