有一个类QWidget不应该作为第二个窗口打开，因此我使用Qt.WindowType.Popup。
一切工作正常，直到您单击应用程序窗口。Event它说
在应用程序窗口外进行了点击，但是当将焦点转移到另一个应用程序或桌面时，我的小部件会关闭，这不是我想要的。所以我尝试重新定义event焦点变化，但
print("The focus is lost, but the window remains open.")根本不起作用。

class AddFriendWidget(QWidget):
    def __init__(self, main_window):
        super().__init__()
        self.main_window = main_window
        self.init_ui()

    def init_ui(self):
        # Layout and widgets
        self.setFixedSize(300, 150)
        add_friend_layout = QVBoxLayout(self)

        self.info_label = QLabel("Enter friend's username:")
        add_friend_layout.addWidget(self.info_label)

        self.friend_input = QLineEdit()
        self.friend_input.setPlaceholderText("Friend's username")
        add_friend_layout.addWidget(self.friend_input)

        self.add_button = QPushButton("Add Friend")
        self.add_button.clicked.connect(self.add_friend)
        add_friend_layout.addWidget(self.add_button)

        self.cancel_button = QPushButton("Cancel")
        self.cancel_button.clicked.connect(self.close)  # Закрываем виджет
        add_friend_layout.addWidget(self.cancel_button)

        self.setWindowFlags(Qt.WindowType.FramelessWindowHint | Qt.WindowType.Popup)
        self.installEventFilter(self)

        return self

    def add_friend(self):
        """Handle adding friend logic here."""
        friend_name = self.friend_input.text().strip()
        if friend_name:
            print(f"Friend '{friend_name}' added.")
        else:
            self.info_label.setText("Please enter a valid username.")


    def eventFilter(self, source, event):
        if event.type() == QEvent.Type.MouseButtonPress:
            global_pos = event.globalPosition().toPoint()  # Получаем координаты клика в глобальном пространстве

            if not self.main_window.geometry().contains(global_pos):
                print("Clicked OUTSIDE the entire application!")
            elif not self.geometry().contains(global_pos):
                print("Clicked outside the widget, but inside the main window.")
            else:
                print("Clicked inside the widget!")

            print(self.isVisible())
            return True
        
        # Проверяем, является ли событие фокусировки QFocusEvent, прежде чем обращаться к `reason()`
        if event.type() == QEvent.Type.FocusOut and isinstance(event, QEvent.FocusOut):
            if event.reason() == Qt.FocusReason.ActiveWindowFocusReason:
                print("The focus is lost, but the window remains open.")
                event.ignore()  
                return True  

        return super().eventFilter(source, event)
