How to inform a QTableView about changes in the underlying QAbstractTablemodel?

[olidem]

Hi!

I'm developing a customer library. I have a model and a view class:

class CustomerLibrary : public QAbstractTableModel
{
//...
public slots:
    void setSeachString (const QString & str){
        _vec_restricted.clear();
        foreach(Customer * c, _vec_all)
            if(c->contains(str)) _vec_restricted.append(c);
    }
private:
    QVector<Customer*> _vec_all;
    QVector<Customer*> _vec_restricted;
}
class CustomerTableView : public QTableView
{
//...
}

class CustomerLibrary : public QAbstractTableModel
{
//...
public slots:
    void setSeachString (const QString & str){
        _vec_restricted.clear();
        foreach(Customer * c, _vec_all)
            if(c->contains(str)) _vec_restricted.append(c);
    }
private:
    QVector<Customer*> _vec_all;
    QVector<Customer*> _vec_restricted;
}
class CustomerTableView : public QTableView
{
//...
}

To copy to clipboard, switch view to plain text mode 

Ok, in order to find quickly an entry, I have a LineEdit whose textChanged signal is connected to the setSearchString(...) method.

So anytime the text changes, drastic changes happen to my model.

How can I inform the view that an update is necessary?
Also I do not want to remove the rows one by one.

Thnaks in advance,
