Question

我在尝试退出多窗口程序时遇到了一些问题，确切地说是2。有一个连接窗口和一个主窗口。如果用户单击连接窗口的本机X按钮，它将关闭，程序结束，一切正常。

但是如果用户连接并且主窗口打开，那么如果用户点击主窗口的X按钮，则窗口将关闭但该过程不会终止。

我尝试了不同的方法，但似乎都没有用，所以这是代码的当前状态：

连接窗口（self.window.connect('delete-event', gtk.main_quit)行被注释，因为delete-event被绑定到我的.glade文件中的quit方法）：

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


class ConnectWinHandler(object):
    def __init__(self, window, builder, gtk):
        self.window = window
        self.builder = builder
        self.gtk = gtk
        # self.window.connect('delete-event', self.gtk.main_quit)

    def connect_button_clicked(self, widget):
        ip, port = self.ip_port_entry.get_text().split(':')
        try:
            # some irrelevant connection logic
        except IOError as ex:
            # irrelevant error handling
        else:
            main_window = MainWin(self.window, self.gtk)
            self.window.close()
            main_window.show_all()

    def quit(self, widget, data=None):
        self.gtk.main_quit()


class ConnectWin(object):
    def __init__(self, gtk):
        self.gtk = gtk
        self.builder = self.gtk.Builder()
        self.builder.add_from_file(r'some_path_to_glade_file')
        self.window = self.builder.get_object('main')
        self.builder.connect_signals(ConnectWinHandler(self.window, self.builder, self.gtk))

    def show_all(self):
        self.window.show_all()
        self.gtk.main()

主窗口（同样，self.window.connect('delete-event', self.gtk.main_quit)被注释，因为delete-event被绑定到我的.glade文件中的quit方法）：

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

class MainWinHandler(object):
    def __init__(self, connect_win, window, builder, gtk):
        self.connect_win = connect_win
        self.window = window
        self.builder = builder
        self.gtk = gtk
        # self.window.connect('delete-event', self.gtk.main_quit)

    def quit(self, widget, data=None):
        self.gtk.main_quit()


class MainWin(object):
    def __init__(self, connect_win, gtk, krpc_handler):
        self.gtk = gtk
        self.builder = self.gtk.Builder()
        self.builder.add_from_file(r'path_to_glade_file')
        self.window = self.builder.get_object('main')
        self.builder.connect_signals(MainWinHandler(connect_win, self.window, self.builder, self.gtk, krpc_handler))

    def show_all(self):
        self.window.show_all()
        self.gtk.main()

我认为这不重要，但每个窗口都在它自己的.py文件中，程序从第三个文件启动：

from gui.connect_win import ConnectWin
from gi.repository import Gtk

connect_win = ConnectWin(Gtk)
connect_win.show_all()

Gtk - 退出多窗口程序
