                                                 wx.DefaultSize,
                                                 wx.TR_HAS_BUTTONS)

        # Clear focused item
        self.tree.ClearFocusedItem()
  
        # expand tree
        self.tree.Expand(self.root)
  
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.tree, 0, wx.EXPAND)
        self.SetSizer(sizer)
