Is there any property for qwidget subclassing tableview to ensure cells visivilty?

[tonnot]

I have a Widget subclassing tableview and I dont know what is happen but when navigate troughout the cells with the arrows the cell is not sincronized, that is , there is a ensurevisible fault.
I have set the same properties of the addressbook example.
Maybe I'm forgetting to set any 'rowcount' 'columncount' property or a function to reimplement ?
Thanks.
