    def __init__(self, parent, title):
        super(Example, self).__init__(parent, title=title, size=(300, 200))

        self.InitUI()

        for i in range(1, 17):
            subp = wx.Panel(p)
            subp.SetBackgroundColour("red")
            gs.Add(subp, 0, wx.EXPAND)

            p.SetSizer(gs)


app = wx.App()
Example(None, title='Grid Demo')
app.MainLoop()

`gs = wx.GridSizer(4, 4, 5, 10)`，其中間距大小`5`為vgap，`10`為hgap
