Pyqt5 - Set an Inputmask on a Qlineedit to type only the "F10" key

Question

I have an app that contains a Qlineedit that when active the user has the option to press the "F10" key and thus open another window.

But I’d like to block that Qlineedit for editing, leaving only available the "F10"

With the property inputMask can do that?

from sys import argv, exit
from PyQt5.QtCore import Qt
from PyQt5.QtWidgets import QApplication, QLineEdit, QVBoxLayout, QWidget, QShortcut, QLabel

class Tela_1(QWidget):
    def __init__(self):
        super(Tela_1, self).__init__()
        self.setWindowTitle("Tela 1 - TESTE")
        self.setGeometry(50, 50, 400, 400) 

        # ADD WIDGETS
        self.lineEdit = QLineEdit()

        # ADD LAYOUT
        mainLayout = QVBoxLayout()
        mainLayout.addWidget(self.lineEdit)
        self.setLayout(mainLayout)

        # AO PRESSIONAR A TECLA "F10" CONECTAR COM A FUNÇÃO "abrir_janela2"
        QShortcut(Qt.Key_F10, self.lineEdit,  self.abrir_janela2, context=Qt.WidgetShortcut)

    def abrir_janela2(self):
        self.janela2 = Tela_2()
        self.janela2.show()

class Tela_2(QWidget):
    def __init__(self):
        super(Tela_2, self).__init__()
        self.setWindowTitle("Tela 2 - TESTE")
        self.setGeometry(50, 50, 300, 300)   
        self.label = QLabel()
        mainLayout = QVBoxLayout()
        mainLayout.addWidget(self.label)
        self.setLayout(mainLayout)
        self.label.setText("TELA 2")    

app = QApplication(argv)
w = Tela_1()
w.show()
exit(app.exec_())

Answer 1

Just apply setReadyOnly(true)

So in Pyqt5:

self.lineEdit.setReadOnly(True)
