wxPython 面板现在显示颜色

Question

我正在用 wxPython 编写一个应用程序，当我转到运行该应用程序时，我希望看到 2 个不同颜色的面板，但我没有。谁能告诉我为什么？

import wx



class Frame(wx.Frame):
    def __init__(self, *args, **kwargs):
        super(Frame, self).__init__(*args, **kwargs)
        self.Center()
        self.Show()

        panel1 = Panel1(self,-1,size=(200,200),pos=(0,0))
        panel2 = Panel2(self,-1,size=(200,200),pos=(210,0))        



class Panel1(wx.Panel):
    def __init__(self, *args, **kwargs):
        super(Panel1,self).__init__(*args, **kwargs)
        self.SetBackgroundColour("PURPLE")

class Panel2(wx.Panel):
    def __init__(self, *args, **kwargs):
        super(Panel2,self).__init__(*args, **kwargs)
        self.SetBackgroundColour("RED")        


if __name__ == "__main__":
    app = wx.App()
    Frame(None,title="MY_PROJECT",size=(500,600))
    app.MainLoop()

import wx



class Frame(wx.Frame):
    def __init__(self, *args, **kwargs):
        super(Frame, self).__init__(*args, **kwargs)
        self.Center()


        panel1 = Panel1(self,-1,size=(200,200),pos=(0,0))
        panel2 = Panel2(self,-1,size=(200,200),pos=(210,0))        

        self.Show()

class Panel1(wx.Panel):
    def __init__(self, *args, **kwargs):
        super(Panel1,self).__init__(*args, **kwargs)
        self.SetBackgroundColour("PURPLE")

class Panel2(wx.Panel):
    def __init__(self, *args, **kwargs):
        super(Panel2,self).__init__(*args, **kwargs)
        self.SetBackgroundColour("RED")        


if __name__ == "__main__":
    app = wx.App()
    Frame(None,title="MY_PROJECT",size=(500,600))
    app.MainLoop()
