Python中使用wxPython开发的一个简易笔记本程序实例

import wx

app = wx.App()
win = wx.Frame(
  None,
  title="simple editor",
  size=(410, 335))

bkg = wx.Panel(win)


def openFile(evt):

    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)
