class Ui_ClickWindow(object):
    def setupUi(self, ClickWindow):
        ClickWindow.setObjectName("ClickWindow")
        ClickWindow.resize(800, 600)
        self.centralwidget = QtWidgets.QWidget(ClickWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.button = QtWidgets.QPushButton(self.centralwidget)
        self.button.setGeometry(QtCore.QRect(70, 90, 641, 341))
        self.button.setIconSize(QtCore.QSize(40, 40))
        self.button.setObjectName("button")
        ClickWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(ClickWindow)

        x = msg.exec_()
        
if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    ClickWindow = QtWidgets.QMainWindow()
    ui = Ui_ClickWindow()
    ui.setupUi(ClickWindow)
    ClickWindow.show()
    sys.exit(app.exec_())

The issue might be with the button connection. Add a print() inside show_popup() to confirm if the method is triggered. If it’s not triggered, check your button’s signal connection.

Here’s the modified version:

def show_popup(self):
    print("Button clicked!")  # Check if triggered
    msg = QMessageBox()
    msg.setWindowTitle("Lame")
    msg.setText("your computer is Lame. Thank you")
    msg.setIcon(QMessageBox.Warning)
    msg.exec_()

If the print shows but no popup appears, check your environment or installation. If no print appears, verify the signal-slot connection.
