本文介绍了使用Python和wxPython库开发一个简单的截屏专家应用的步骤，包括创建菜单、添加功能以及基本的用户界面设计。

1、main.py

#!/usr/bin/env python
#Boa:App:BoaApp

import wx

import mainFrame

modules ={'mainFrame': [1, 'Main frame of Application', 'mainFrame.py']}

class BoaApp(wx.App):
    def OnInit(self):
        self.main = mainFrame.create(None)
        self.main.Show()
        self.SetTopWindow(self.main)
        return True

def main():
    application = BoaApp(0)
    application.MainLoop()

if __name__ == '__main__':
    main()

2、mainFrame.py
关键：
1、wx.MenuItem才有菜单事件
2、self.Bind( wx.EVT_MENU, self.dostart, id = self.oper_start_item.GetId() )


# -*- coding: utf-8 -*- 

import wx

def create(parent):
    return mainFrame(parent)

class mainFrame ( wx.Frame ):

	def __init__( self, parent ):
		wx.Frame.__init__ ( self, parent, id = wx.ID_ANY, title = u"截屏专家", pos = wx.DefaultPosition, size = wx.Size( 508,319 ), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL )

		self.SetSizeHintsSz( wx.DefaultSize, wx.DefaultSize )

		self.mf_menubar = wx.MenuBar( 0 )
		self.oper_menu = wx.Menu()
		self.oper_start_item = wx.MenuItem( self.oper_menu, wx.ID_ANY, u"启动", wx.EmptyString, wx.ITEM_NORMAL )
		self.oper_menu.AppendItem( self.oper_start_item )

		self.oper_stop_item = wx.MenuItem( self.oper_menu, wx.ID_ANY, u"终止", wx.EmptyString, wx.ITEM_NORMAL )
		self.oper_menu.AppendItem( self.oper_stop_item )

		self.mf_menubar.Append( self.oper_menu, u"操作" ) 

		self.set_menu = wx.Menu()
		self.set_sys_item = wx.MenuItem( self.set_menu, wx.ID_ANY, u"系统设置", wx.EmptyString, wx.ITEM_NORMAL )
		self.set_menu.AppendItem( self.set_sys_item )

		self.mf_menubar.Append( self.set_menu, u"设置" ) 

		self.help_menu = wx.Menu()
		self.mf_menubar.Append( self.help_menu, u"帮助" ) 

		self.SetMenuBar( self.mf_menubar )

		self.mf_statusBar = self.CreateStatusBar( 1, wx.ST_SIZEGRIP, wx.ID_ANY )
		mf_sizer = wx.BoxSizer( wx.HORIZONTAL )

		self.SetSizer( mf_sizer )
		self.Layout()

		self.Centre( wx.BOTH )

		# Connect Events
		self.Bind( wx.EVT_MENU, self.dostart, id = self.oper_start_item.GetId() )

	def __del__( self ):
		pass


	# Virtual event handlers, overide them in your derived class
	def dostart( self, event ):
		print 'sdfsdf'
