例子

代码：

#!/usr/bin/env python3# Created by xiaosanyu at 16/6/14# section 009TITLE = "LinkButton"DESCRIPTION = """A Gtk.LinkButton is a Gtk.Button with a hyperlink, similar to the one used by web browsers,which triggers an action when clicked.It is useful to show quick links to resources.The ::activate-link signal is emitted each time the Gtk.LinkButton has been clicked.The default handler will call Gtk.show_uri() with the URI stored inside the Gtk.LinkButton :uri property.To override the default behavior, you can connect to the ::activate-link signaland stop the propagation of the signal by returning True from your handler.you need to install gvfs to get support for uri schemes such as http:// or ftp://,as only local files are handled by GIO itself"""import giimport webbrowsergi.require_version('Gtk', '3.0')from gi.repository import Gtkclass LinkButtonWindow(Gtk.Window):    def __init__(self):        Gtk.Window.__init__(self, title="LinkButton Demo")        self.set_border_width(10)        # button = Gtk.LinkButton(uri="file:///Users/xiaosanyu/mydocbook/docbook.html", label="Visit GTK+ Homepage")        button = Gtk.LinkButton(uri="http://www.gnome.org", label="Visit GTK+ Homepage")        button.connect("activate-link", self.visit)        self.add(button)    def visit(self, btn):        webbrowser.open(btn.get_uri())        return Truedef main():    win = LinkButtonWindow()    win.connect("delete-event", Gtk.main_quit)    win.show_all()    Gtk.main()if __name__ == "__main__":    main()

创建一个Gtk.LinkButton，绑定“activate-link”信号到visit方法

button = Gtk.LinkButton(uri="http://www.gnome.org", label="Visit GTK+ Homepage")        button.connect("activate-link", self.visit)        self.add(button)def visit(self, btn):    webbrowser.open(btn.get_uri())    return True

当点击链接时，执行visit方法，使用Python自带webbrowser模块打开URI。并且返回True。

说明：默认点击时如果报错
Unable to show ‘http://www.gnome.org‘: 不支持该操作
需要安装“gvfs”

安装gvfs

jhbuild build gvfs

这个模块装起来比较麻烦，遇到各种各样的问题，最后装上后，点击链接依然报这个错，遂放弃。
如有在MAC上直接能打开此链接的同学，还请告知方法~~
