python实现的文本编辑器

wxpython实现的文本编辑器

效果如下：

主要功能：

1.编辑保存文本，打开修改文本

2.常用快捷键，复制，粘贴，全选等

3.支持撤销功能

代码如下：

#encoding=utf-8

import wx
import os

class MyFrame(wx.Frame):
    def __init__(self):
        self.file=''
        self.content=[]
        self.count=0
        self.width=700
        self.height=500
        wx.Frame.__init__(self,None,-1,u'记事本',size=(self.width,self.height))
        self.panel=wx.Panel(self,-1)
        menubar=wx.MenuBar()
        menu1=wx.Menu()
        menubar.Append(menu1,u'文件')
        menu1.Append(1001,u'打开')
        menu1.Append(1002,u'保存')
        menu1.Append(1003,u'另存为')
        menu1.Append(1004,u'退出')
        menu2=wx.Menu()
        menubar.Append(menu2,u'编辑')
        menu2.Append(2001,u'撤销')
        menu2.Append(2002,u'清空')
        menu2.Append(2003,u'剪切')
        menu2.Append(2004,u'复制')
        menu2.Append(2005,u'粘贴')
        menu2.Append(2006,u'全选',)
