一、简介

wxPython是Python语言的一套优秀的GUI图形库，允许Python程序员很方便的创建完整的、功能键全的GUI用户界面。 wxPython是作为优秀的跨平台GUI库wxWidgets的Python封装和Python模块的方式提供给用户的。

二、安装

参考官方网站：http://www.wxpython.org/download.php

三、DEMO

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()

运行效果：
