简单使用下QLineEdit类中的方法。

方法	作用
setReadOnly(self, arg__1:bool)	设置只读
setText(self, arg__1:str)	设置内容
text(self)	获取内容

import sys
from PySide6.QtWidgets import QApplication, QMainWindow
from ui_test import Ui_MainWindowclass MainWindow(QMainWindow):def __init__(self):super().__init__()self.ui = Ui_MainWindow()self.ui.setupUi(self)self.ui.pushButton.clicked.connect(self.pushbuttonSlot)self.ui.lineEdit.setReadOnly(True)self.ui.lineEdit.setText("QLineEdit")def pushbuttonSlot(self):print(self.ui.lineEdit.text())if __name__ == "__main__":app = QApplication(sys.argv)mainwindow = MainWindow()mainwindow.show()sys.exit(app.exec())
