python2上的Wxpython GUI不一样

Question

我正在尝试将用python3编写的代码更改为python2.4。 Python3版本代码在窗口上运行良好，但在python2.4和Centos5.11中，即使运行相同的代码，GUI也不相同。

窗口中的

，python3

in centos，python2.4

gui代码如下：

class Panel(wx.Panel):
global WTIME
def __init__(self, parent, site):
    wx.Panel.__init__(self, parent,wx.ID_ANY, pos=wx.DefaultPosition, size=wx.Size(600,100), style=wx.TAB_TRAVERSAL)
    self.site = site
    bSizer = wx.BoxSizer(wx.VERTICAL)
    self.canvas = PlotCanvas(self, 0)
    self.canvas.SetYSpec("none")
    self.canvas.Draw(drawBarGraph(self.site), xAxis=(0,12), yAxis=(0,1))
    bSizer.Add(self.canvas, 1, wx.EXPAND)
    self.SetSizer(bSizer)
    self.canvas.SetEnableGrid(False)
    self.Layout()

def updateGraph(self, site_log):
    self.canvas.Draw(drawBarGraph(self.site, site_log), xAxis=(0,WTIME), yAxis=(0,1))

class MainFrame(wx.Frame):
def __init__(self):
    """Constructor"""
    wx.Frame.__init__(self, None, title="NoName", size=(1250,500))
    self.scroll = wx.ScrolledWindow(self, -1, size=(1250,500))
    self.scroll.SetScrollbars(1,1,1400,1600)

    topSizer = wx.BoxSizer(wx.VERTICAL)

    panelSizer1 = wx.BoxSizer(wx.HORIZONTAL)
    panelSizer2 = wx.BoxSizer(wx.HORIZONTAL)
    panelSizer3 = wx.BoxSizer(wx.HORIZONTAL)
    panelSizer4 = wx.BoxSizer(wx.HORIZONTAL)
    self.p1 = Panel(self.scroll, "SITE1")
    self.p2 = Panel(self.scroll, "SITE2")
    self.p3 = Panel(self.scroll, "SITE3")
    self.p4 = Panel(self.scroll, "SITE4")
    self.p5 = Panel(self.scroll, "SITE5")
    self.p6 = Panel(self.scroll, "SITE6")
    self.p7 = Panel(self.scroll, "SITE7")
    self.p8 = Panel(self.scroll, "SITE8")
    self.panels = [self.p1, self.p2, self.p3, self.p4, self.p5, self.p6, self.p7, self.p8]

    panelSizer1.Add(self.p1, 0, wx.ALL|wx.EXPAND,5)
    panelSizer1.Add(self.p2, 0, wx.ALL|wx.EXPAND,5)
    panelSizer2.Add(self.p3, 0, wx.ALL|wx.EXPAND,5)
    panelSizer2.Add(self.p4, 0, wx.ALL|wx.EXPAND,5)
    panelSizer3.Add(self.p5, 0, wx.ALL|wx.EXPAND,5)
    panelSizer3.Add(self.p6, 0, wx.ALL|wx.EXPAND,5)
    panelSizer4.Add(self.p7, 0, wx.ALL|wx.EXPAND,5)
    panelSizer4.Add(self.p8, 0, wx.ALL|wx.EXPAND,5)

    topSizer.Add(panelSizer1, 0, wx.ALL|wx.EXPAND, 5)
    topSizer.Add(panelSizer2, 0, wx.ALL|wx.EXPAND, 5)
    topSizer.Add(panelSizer3, 0, wx.ALL|wx.EXPAND, 5)
    topSizer.Add(panelSizer4, 0, wx.ALL|wx.EXPAND, 5)
    self.scroll.SetSizer(topSizer)
    topSizer.Fit(self.scroll)



    menu = wx.Menu()
    windowtimemenu = menu.Append(101, "Set Window Time", "Minute")
    self.Bind(wx.EVT_MENU, self.OnSetWtime, windowtimemenu)
    menu.Append(wx.ID_ABOUT, "About", "About")
    exitmenu = menu.Append(wx.ID_EXIT, "EXIT", "Close")
    self.Bind(wx.EVT_MENU, self.OnExit, exitmenu)
    menubar = wx.MenuBar()
    menubar.Append(menu, "Menu")
    self.Bind(wx.EVT_CLOSE, self.OnCloseWindow)
    self.e = threading.Event()
    self.SetMenuBar(menubar)

    self.Show()

我的问题......

1. wxpython在py2，py3上的运行方式是否有所不同？
2. 如何在像windows这样的centos上显示相同的GUI。
