        self.SetCellValue(6, 0, "one")
        self.SetCellEditor(7, 0, grid.GridCellBoolEditor())
        self.SetCellValue(7, 0, "True")

class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, -1, u"单元格的设置", size=(450,250))
        self.grid = SimpleGrid(self)

class MyApp(wx.App):
    def OnInit(self):
        self.frame = MyFrame()
        self.frame.Show()
        return True

app = MyApp()
app.MainLoop()

结合这些，读者应该可以写出一个比较高级的单元格程序了
