QAbstractItemModel / QStyledItemDelegate howto update data on value changed?

[moviemax]

Ups, some post get lost somewhere ???
Thanks Santosh, but I dosn`t connect anything it goes autmaticaly by

mapper_r1.addMapping

mapper_r1.addMapping

To copy to clipboard, switch view to plain text mode 

Maybe I have to derive QTableView and QDataWidgetMapper to force some signals

I improved the code to

mapper_r2 = QtGui.QDataWidgetMapper(this)                
        mapper_r2.setModel(otpmodel)
        mapper_r2.addMapping(label_row2, 0, "text")
        mapper_r2.addMapping(spinbox_row2, 1)        
        mapper_r2.setCurrentIndex(1)
        connect(
                spinbox_row2, SIGNAL(valueChanged(),  otpmodel, SLOT(dataChanged()))
         )
       mapper_r2.setSubmitPolicy(QtGui.QDataWidgetMapper.AutoSubmit)

mapper_r2 = QtGui.QDataWidgetMapper(this)                
        mapper_r2.setModel(otpmodel)
        mapper_r2.addMapping(label_row2, 0, "text")
        mapper_r2.addMapping(spinbox_row2, 1)        
        mapper_r2.setCurrentIndex(1)
        connect(
                spinbox_row2, SIGNAL(valueChanged(),  otpmodel, SLOT(dataChanged()))
         )
       mapper_r2.setSubmitPolicy(QtGui.QDataWidgetMapper.AutoSubmit)

To copy to clipboard, switch view to plain text mode 

But as expected, the value isn`t set to the model already , so an dataChanged() isn`t enough

There is no such SLOT in QAbstractItemModel
