QLineEdit readOnly disables clear button as well

Question

Essentially this post describes the problem however the answers are for c++ and I'd like to know if there is a way to do this in python.

Turning a lineedit into readOnly mode also disables the clearButton and I wondered if it is possible to keep the clearButton functionality active. Is it possible to extend the action that gets triggered on a clearButton click with some custom functionality (if it is possible to access the clearbutton at all)?

When readOnly is set to QLineEdit it disables QToolButton (clear button), so the solution is to enable it, and for this you must obtain the button using the findChild() method:

from PySide2 import QtWidgets


if __name__ == "__main__":
    import sys

    app = QtWidgets.QApplication(sys.argv)
    le = QtWidgets.QLineEdit(
        text="Stack Overflow", readOnly=True, clearButtonEnabled=True
    )
    le.findChild(QtWidgets.QToolButton).setEnabled(True)
    le.show()
    sys.exit(app.exec_())
