Filter in QListView

[derilshows]

I do the query and show that in QListView.

    QSqlQueryModel * model = new QSqlQueryModel(0);
    model->setQuery("select ......");

How to make a filter? When I will write smth in QLineEdit, the QListView will refresh with that filter? If I'll make QLineEdit clear, the QListView will show model, that shows basically.
