@aadil50 You import the generated Python module. Create an instance of Ui_MainWindow and add it to your tab layout.

How can i do it? I have done, If you observe I have done it in comments.. It gives me error from ui file.. "AttributeError: 'First' object has no attribute 'setCentralWidget' "

@aadil50 said in How can I add Tab as UI file from qtdesigner converted file PYQT5?:

setCentralWidget

QWidget has no central widget, only QMainWindow has one.
