    I have two treeview, in a one I do "copy" and in the other I do "paste", but when I click "paste" QVariant definitivo = _treeView->model()->data(index) , data results invalid, beacuse I don't click in a row, so How can I write? if (data == invalid) results there is an error

      Hi,

      QVariant has a method for that: QVariant::isValid.
