如何在按QPushButton时查找动态创建的QLineEdit

from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QPushButton, QLineEdit

class MyWidget(QWidget):
    def __init__(self):
        super().__init__()
        self.layout = QVBoxLayout()
        self.setLayout(self.layout)

        self.button = QPushButton("查找QLineEdit")
        self.button.clicked.connect(self.findLineEdits)
        self.layout.addWidget(self.button)

    def findLineEdits(self):
        lineEdits = self.findChildren(QLineEdit)
        for lineEdit in lineEdits:
            # 对每个找到的QLineEdit进行操作
            text = lineEdit.text()
            print("找到的QLineEdit文本内容：", text)

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