wxpython记事本

下面是一个简单的wxPython记事本的示例代码：

import wx

class MyFrame(wx.Frame):
    def __init__(self, parent, title):
        wx.Frame.__init__(self, parent, title=title, size=(400, 400))
        self.control = wx.TextCtrl(self, style=wx.TE_MULTILINE)
        self.CreateStatusBar() 
        filemenu = wx.Menu()
        menuOpen = filemenu.Append(wx.ID_OPEN, "&Open", "Open a file")
        menuSave = filemenu.Append(wx.ID_SAVE, "&Save", "Save file")
        menuAbout = filemenu.Append(wx.ID_ABOUT, "&About", "Information about this program")
        filemenu.AppendSeparator()
        menuExit = filemenu.Append(wx.ID_EXIT, "E&xit", "Terminate the program")
        menuBar = wx.MenuBar()
        menuBar.Append(filemenu, "&File")
        self.SetMenuBar(menuBar)
        self.Bind(wx.EVT_MENU, self.OnOpen, menuOpen)
        self.Bind(wx.EVT_MENU, self.OnSave, menuSave)
        self.Bind(wx.EVT_MENU, self.OnAbout, menuAbout)
        self.Bind(wx.EVT_MENU, self.OnExit, menuExit)
        self.Show(True)

    def OnAbout(self,e):
        dlg = wx.MessageDialog(self, " A simple text editor", "About Sample Editor", wx.OK)
        dlg.ShowModal()
        dlg.Destroy()

    def OnExit(self,e):
        self.Close(True)

    def OnOpen(self,e):
        """ Open a file"""
        dlg = wx.FileDialog(self, "Choose a file", self.dirname, "", "*.*", wx.OPEN)
        if dlg.ShowModal() == wx.ID_OK:
            self.filename = dlg.GetFilename()
            self.dirname = dlg.GetDirectory()
            f = open(os.path.join(self.dirname, self.filename), 'r')
            self.control.SetValue(f.read())
            f.close()
        dlg.Destroy()

    def OnSave(self,e):
        """ Save a file"""
        dlg = wx.FileDialog(self, "Save file", self.dirname, "", "*.*", wx.SAVE | wx.OVERWRITE_PROMPT)
        if dlg.ShowModal() == wx.ID_OK:
            self.filename = dlg.GetFilename()
            self.dirname = dlg.GetDirectory()
            f = open(os.path.join(self.dirname, self.filename), 'w')
            f.write(self.control.GetValue())
            f.close()
        dlg.Destroy()

app = wx.App(False)
frame = MyFrame(None, 'Simple Editor')
app.MainLoop()

这个记事本具有基本的文件打开、保存、退出和关于等功能。你可以根据需要进行修改和扩展。
