在一个过程中，用标头键移动Python GTK3窗口

Question

我喜欢GTK标头。但是当我使用它时，我无法在过程中移动窗口。阻止标题冻结我的窗户的好方法是什么？

问候

示例代码：

#!/usr/bin/env python
#-*- coding: utf-8 -*-
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
import time

class MyWindow(Gtk.Window):
    def __init__(self):
        Gtk.Window.__init__(self, title="HeaderBarTest")
        self.connect("destroy", lambda w: Gtk.main_quit())
        self.set_position(Gtk.WindowPosition.CENTER)
        self.set_default_size(300, 300)
        self.set_border_width(20)
        # header bar
        if True:
            hb = Gtk.HeaderBar()
            hb.set_show_close_button(True)
            hb.props.title = "HeaderBarTest"
            self.set_titlebar(hb)
        self.box = Gtk.Box(spacing=6)
        self.add(self.box)
        self.button = Gtk.Button(label="Sleep")
        self.box.pack_start(self.button, True, True, 0)
        self.button.connect("clicked", self.sleep_function)
        self.show_all()
        Gtk.main()
    def sleep_function(self, widget=None):
        time.sleep(10)

if __name__ == "__main__":
    app = MyWindow()

编辑：单击Python GTK3中的按钮后窗口冻结

一个解决方法是使用多处理：

#!/usr/bin/env python
#-*- coding: utf-8 -*-
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
import time
from multiprocessing import Process

class MyWindow(Gtk.Window):
    def __init__(self):
        Gtk.Window.__init__(self, title="HeaderBarTest")
        self.connect("destroy", lambda w: Gtk.main_quit())
        self.set_position(Gtk.WindowPosition.CENTER)
        self.set_default_size(300, 300)
        self.set_border_width(20)
        # header bar
        if True:
            hb = Gtk.HeaderBar()
            hb.set_show_close_button(True)
            hb.props.title = "Convert2Html"
            self.set_titlebar(hb)
        self.box = Gtk.Box(spacing=6)
        self.add(self.box)
        self.button = Gtk.Button(label="Sleep")
        self.box.pack_start(self.button, True, True, 0)
        self.button.connect("clicked", self.on_sleep_button_clicked)
        self.show_all()
        Gtk.main()
    def on_sleep_button_clicked(self, widget):
        p = Process(target=self.sleep_function)
        p.start()
    def sleep_function(self, widget=None):
        print "start"
        time.sleep(6)
        print "end"
if __name__ == "__main__":
    app = MyWindow()
