本文实例讲述了wxPython窗口的继承机制，分享给大家供大家参考。具体分析如下：

示例代码如下：

import wx  
 
class MyApp(wx.App): 
  def OnInit(self): 
    self.frame = MyFrame(None, title = "My Main Frame jb51.net") 
    self.SetTopWindow(self.frame) 
    self.frame.Show() 
 
    return True 
 
class MyFrame(wx.Frame): 
  def __init__(self, parent, id=wx.ID_ANY, title=""): 
    super(MyFrame, self).__init__(parent, id , title)  
 
      # Attributes  
    self.panel = wx.Panel(self) 
    self.panel.SetBackgroundColour(wx.BLACK)#设置面板的背景色为黑色，wx.BLACK为大写，在此犯过错 
    self.button = wx.Button(self.panel, label="push me", pos=(50, 50))#一个按钮的属性,按钮的父窗口为panel 
 
if __name__ == "__main__": 
  app = MyApp() 
  app.MainLoop()

其中的wx.Button函数介绍如下：

wx.Button (wxWindow *parent, wxWindowID id, const wxString &label=wxEmptyString, const wxPoint &pos=wxDefaultPosition, const wxSize &size=wxDefaultSize, long style=0, const wxValidator &validator=wxDefaultValidator, const wxString &name=wxButtonNameStr)
Constructor, creating and showing a button.

三层窗口框架：

1. frame或dialog
2. panel或notebooks...
3. controls
