QTabWidget: How to add a layout to a tab?

[Mohammad_Aqajani]

setCurrentIndex method of QTabWidget class takes a QWidget object as an argument so:
all you have to do is create a new QWidget object and use the setLayout method to set your layout to that object:
yourLayout = QVBoxLayout() #or whatever else
w = QWidget()
w.setLayout( yourLayout )
addTab(w)
