Question

我想将回调连接到标签文本

例如在以下代码中

import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk as gtk
from gi.repository import Gdk as gdk

def hello(*args):
    print "hello, this is most used text editor for pyton"

def wellcome(*args):
    print "wellcome to the our program please update to premium version"


w = gtk.Window(title = "example", type = gtk.WindowType.TOPLEVEL)
w.resize(300, 200)

mylabel = gtk.Label()
mylabel.set_markup("""please read """
                   """<span underline = "single" command = "hello">hello</span> or """
                   """<span underline = "single" command = "wellcome">wellcome</span>""")


w.add(mylabel)
w.show_all()
gtk.main()

我知道，pango span属性不包含命令选项，好的。还有另一种方法吗？

您可以通过将处理程序连接到activate-link信号来实现此目的。请注意，回调的签名与按钮单击不同，您应该返回True以停止进一步处理。

import gi

gi.require_version('Gtk', '3.0')
from gi.repository import Gtk

class MyWindow(Gtk.Window):

    def __init__(self):
        Gtk.Window.__init__(self, title="Hello World")

        label = Gtk.Label()
        label.set_markup('<a href="mylink">Click Here</a> but not here.')
        label.connect("activate-link", self.on_link_clicked)
        self.add(label)

    def on_link_clicked(self, label, uri):
        print("%s clicked" % uri)
        return True

win = MyWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()

import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk

class MyWindow(Gtk.Window):

    def __init__(self):
        Gtk.Window.__init__(self, title="Hello World")

        label = Gtk.Label()
        label.set_markup('please read <a href="hello">Hello</a> or <a href="wellcome">wellcome</a>')
        label.connect("activate-link", self.on_link_clicked)
        self.add(label)

    def hello(self):
        print "hello, this is most used text editor for pyton"

    def wellcome(self):
        print "wellcome to the our program please update to premium version"

    def on_link_clicked(self, label, uri):
        print("%s clicked" % uri)

        if uri == "hello":
            self.hello()
        elif uri == "wellcome":
            self.wellcome()

        return True

win = MyWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()

PyGTK如何将不同的回调绑定到标签上的每个可点击文本？
