Pyqt 打开外部链接的几种方法

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))
