Black Cat

I've try to create an event to detect if the arrow up key was pressed but it don't work. Someone know whats wrong if the script?

File 1

import sys
from PySide2 import QtCore, QtGui, QtWidgets
from podedeletar import Ui_MainWindow

class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()
        self.setupUi(self)
        
    
if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec_())

File 2

from PySide2.QtCore import *
from PySide2.QtGui import *
from PySide2.QtWidgets import *
from PySide2 import QtCore, QtWidgets

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        if not MainWindow.objectName():
            MainWindow.setObjectName(u"MainWindow")
        MainWindow.resize(800, 600)
        self.centralwidget = QWidget(MainWindow)
        self.centralwidget.setObjectName(u"centralwidget")
        self.lineEdit = QLineEdit(self.centralwidget)
        self.lineEdit.setObjectName(u"lineEdit")
        self.lineEdit.setGeometry(QRect(330, 250, 113, 20))
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QMenuBar(MainWindow)
        self.menubar.setObjectName(u"menubar")
        self.menubar.setGeometry(QRect(0, 0, 800, 21))
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QStatusBar(MainWindow)
        self.statusbar.setObjectName(u"statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)

        QMetaObject.connectSlotsByName(MainWindow)

        lay = QtWidgets.QVBoxLayout(self)
        lay.addWidget(self.lineEdit)
        lay.addStretch()

        self.lineEdit.installEventFilter(self)

    def eventFilter(self, obj, event):
        if obj is self.lineedit and event.type() == QtCore.QEvent.KeyPress:
            if event.key() == QtCore.Qt.Key_Up:
                self.call_sc()
        return super().eventFilter(obj, event)

    def call_sc(self):
        print("working")

    def retranslateUi(self, MainWindow):
        MainWindow.setWindowTitle(QCoreApplication.translate("MainWindow", u"MainWindow", None))

Hi,

Ui_MainWindow is not a QObject nor a QWidget. You should not modify it as it is generated code.

You should implement your logic in MainWindow.
