Question

我想完成以下代码，以便在单击窗口小部件关闭窗口时销毁窗口。

#!/usr/bin/env python

from gi.repository import Gtk, Gio
import sys

class MyWindow(Gtk.ApplicationWindow):
    def __init__(self, app):
        Gtk.Window.__init__(self, title="Menubutton Example", application=app)
        self.set_default_size(600, 400)

        grid = Gtk.Grid()

        menubutton = Gtk.MenuButton()
        menubutton.set_size_request(80, 35)
        grid.attach(menubutton, 0, 0, 1, 1)

        menumodel = Gio.Menu()
        menubutton.set_menu_model(menumodel)
        menumodel.append("New", "app.new")
        menumodel.append("Quit", "app.quit")

        self.add(grid)

class MyApplication(Gtk.Application):
    def __init__(self):
        Gtk.Application.__init__(self)

    def do_activate(self):
        win = MyWindow(self)
        win.show_all()

    def do_startup(self):
        Gtk.Application.do_startup(self)

        new_action = Gio.SimpleAction.new("new", None)
        new_action.connect("activate", self.new_callback)
        self.add_action(new_action)

        quit_action = Gio.SimpleAction.new("quit", None)
        quit_action.connect("activate", self.quit_callback)
        self.add_action(quit_action)

    def new_callback(self, action, parameter):
        print("You clicked \"New\"")

    def quit_callback(self, action, parameter):
        print("You clicked \"Quit\"")
        self.quit()

app = MyApplication()
exit_status = app.run(sys.argv)
sys.exit(exit_status)

如果此处有任何问题代码 http://learngtk.org/tutorials/python_gtk3_tutorial/html/application.html

当我点击窗口的左上方以销毁它时，它会阻止它，并且在我收到消息之后：是否要强制应用程序离开或期待任何答案？
