python - PyGTK弃用警告 : What am I missing?

Question

我的代码工作正常，但当我运行脚本时，我在终端中收到此警告。我错过了什么？

abc.py:10: PyGTKDeprecationWarning: Using positional arguments with the GObject constructor has been deprecated. Please specify keyword(s) for "label" or use a class specific constructor. See: https://wiki.gnome.org/PyGObject/InitializerDeprecations
actor_act = Gtk.Button("Click Here")

脚本名称:abc.py

实际代码:

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

def actor(button):
    print('Simple Button')

boxy = Gtk.Window(title="Hello")
boxy.set_default_size(500,500)
actor_act = Gtk.Button("Click Here")
boxy.add(actor_act)

actor_act.connect("clicked", actor)
boxy.connect("destroy", Gtk.main_quit)

boxy.show_all()
Gtk.main()
