    本demo是一个简单的记事本软件,可以打开文件,修改并保存。

    import wx
    
    app = wx.App()
    win = wx.Frame(
        None,
        title="simple editor",
        size=(410, 335))
    
    bkg = wx.Panel(win)
    
    
    def openFile(evt):
        dlg = wx.FileDialog(
            win,
            "Open",
            "",
            "",
            "All files (*.*)|*.*",
            wx.FD_OPEN | wx.FD_FILE_MUST_EXIST)
        filepath = ''
        if dlg.ShowModal() == wx.ID_OK:
            filepath = dlg.GetPath()
        else:
            return
        filename.SetValue(filepath)
        fopen = open(filepath)
        fcontent = fopen.read()
        contents.SetValue(fcontent)
        fopen.close()
    
    
    def saveFile(evt):
        fcontent = contents.GetValue()
        fopen = open(filename.GetValue(), 'w')
        fopen.write(fcontent)
        fopen.close()
    
    openBtn = wx.Button(bkg, label='open')
    openBtn.Bind(wx.EVT_BUTTON, openFile)
    
    saveBtn = wx.Button(bkg, label='save')
    saveBtn.Bind(wx.EVT_BUTTON, saveFile)
    
    filename = wx.TextCtrl(bkg, style=wx.TE_READONLY)
    contents = wx.TextCtrl(bkg, style=wx.TE_MULTILINE)
    
    hbox = wx.BoxSizer()
    hbox.Add(openBtn, proportion=0, flag=wx.LEFT | wx.ALL, border=5)
    hbox.Add(filename, proportion=1, flag=wx.EXPAND | wx.TOP | wx.BOTTOM, border=5)
    hbox.Add(saveBtn, proportion=0, flag=wx.LEFT | wx.ALL, border=5)
    
    bbox = wx.BoxSizer(wx.VERTICAL)
    bbox.Add(hbox, proportion=0, flag=wx.EXPAND | wx.ALL)
    bbox.Add(
        contents,
        proportion=1,
        flag=wx.EXPAND | wx.LEFT | wx.BOTTOM | wx.RIGHT,
        border=5)
    
    bkg.SetSizer(bbox)
    win.Show()
    app.MainLoop()
