What you should do is create a signal and output it as shown below:

class ClickableQTabWidget(QTabWidget):
    clicked = pyqtSignal()
    def mousePressEvent(self, event):
        self.clicked.emit()

class Widget(QWidget):
    def __init__(self, parent=None):
        QWidget.__init__(self, parent)
        self.setLayout(QVBoxLayout())
        self.cw = ClickableQTabWidget(self)
        self.layout().addWidget(self.cw)
        self.cw.clicked.connect(self.onClicked)

    def onClicked(self):
        print("clicked")

app = QApplication(sys.argv)

widget = Widget()
widget.show()

app.exec_()
