如何避免在PySide中同时获得多个焦点？

from PySide2.QtWidgets import QApplication, QWidget, QLineEdit

class MyWidget(QWidget):
    def __init__(self):
        super().__init__()
        self.setFocusPolicy(Qt.ClickFocus)  # 设置焦点策略为点击获取焦点

    def focusInEvent(self, event):
        # 控件获得焦点时的处理逻辑
        print("Focus in")
        super().focusInEvent(event)

    def focusOutEvent(self, event):
        # 控件失去焦点时的处理逻辑
        print("Focus out")
        super().focusOutEvent(event)

if __name__ == "__main__":
    app = QApplication([])
    widget = MyWidget()
    widget.show()
    app.exec_()
