wxPython example代码笔记

一份示例代码，备用查阅。

import wx
import wx.html
import wx.adv
from wx.lib.wordwrap import wordwrap
import webbrowser  
# webbrowser是python自带的模块，用于操作浏览器。
# 可以看这个网页：https://blog.csdn.net/ichocolatekapa/article/details/23941165
# webbrowser.open(url[, new=0[, autoraise=1]])
# 如果new = 0, 那么url会在同一个浏览器窗口下打开，如果new = 1, 会打开一个新的窗口，如果new = 2, 会打开一个新的tab, 如果autoraise ＝ true, 窗口会自动增长。
# webbrowser.open_new(url) or webbrowser.open_new_tab(url) 
# 输入的 url 不要丢掉“http://”
