Extract QStandardItemModel from QTableView

[patrik08]

I make 20 QTableView table from QStandardItemModel
only by table -> setModel ( QAbstractItemModel * model )

At end to print table i wand back the model

QAbstractItemModel * QAbstractItemView::model () const

now how i can convert QAbstractItemModel to QStandardItemModel without subclass the model?

Text and color i set on QStandardItemModel , i want only back my data how?

I can extract only from QStandardItemModel :-( and print on this way.....

now how i can convert QAbstractItemModel to QStandardItemModel without subclass the model?

If I understood your question properly then the answer is "qobject_cast" or "dynamic_cast". And please stop posting code that is irrelevant to the question.
