Pyqt 触发一个事件，打开外部链接，我找到了这个方法，供大家参考
1. QDesktopServices 的openUrl 方法
1 QtGui.QDesktopServices.openUrl(QtCore.QUrl(‘http://www.hao123.com‘))
2.Python 自带的webbrowser 浏览器控制模块
webbrowser提供了三种方法
1 import webbrowser 2 webbrowser.open(url, new=0, autoraise=True) 3 webbrowser.open_new(url) 4 webbrowser.open_new_tab(url)
3.部分控件的Link属性链接
Pyqt有几个控件带有 setOpenExternalLinks ， 如 QTextLabel 、 QTextBrowser 等
当 setOpenExternalLinks 值为TURE 表示可通过html 添加 A 标签打开外部链接, 如设置：
self.label.setOpenExternalLinks(True)
1 self.label.setText(_translate("MainWindow", "<html><head/><body><p><a href=\"http://www.baidu.com\"><span style=\" text-decoration: underline; color:#0000ff;\">百度首页</span></a></p></body></html>", None))
