Answer 1

处理delete-event信号。返回False关闭，True返回取消。

Answer 2

以下是我如何使用它：

# in constructor:
        self.connect('destroy', gtk.main_quit)
        self.connect('delete-event', self.on_destroy)

    def on_destroy(self, widget=None, *data):
        # return True --> no, don't close

        messagedialog = gtk.MessageDialog(parent=self, flags= gtk.DIALOG_MODAL & gtk.DIALOG_DESTROY_WITH_PARENT, 
                                          type=gtk.MESSAGE_QUESTION, buttons=gtk.BUTTONS_OK_CANCEL, message_format="Click on 'Cancel' to leave the application open.")
        messagedialog.show_all()
        result=messagedialog.run()
        messagedialog.destroy()
        if result==gtk.RESPONSE_CANCEL:
            return True
        return False
