pyqt如何监听对话框关闭?我的方法也能实现，有没有更好的方法?

Question

self.dialog = LinkManagerDialog(self.event, self.c)    
self.dialog.setWindowFlags(Qt.WindowType.WindowStaysOnTopHint)    
self.dialog.window_closed_listener = lambda :print('隐藏了')

from PyQt5.QtWidgets import QDialog, QMessageBox

from Config import Config
from LinkManagerDialogBase import Ui_Dialog


class LinkManagerDialog(QDialog, Ui_Dialog):
    def __init__(self, event, config: Config):
        super(LinkManagerDialog, self).__init__()
        self.setupUi(self)
        self.window_closed_listener = None
        self.event = event

    def closeEvent(self, a0) -> None:
        if self.window_closed_listener is not None:
            self.window_closed_listener()
