QObjectList porting problem

[batileon]

From QT3 to QT4, QObjectList should have changed.
How can I convert the following QT3 code to QT4?

QObjectList *l = this->queryList( "TableButton" );    // get all its children which is TableButton
        QObjectListIt it( *l ); // iterate over the buttons
 
        while ( it.current() != 0 )
        {
            // for each found button...
            ((TableButton *)(it.current()))->close( TRUE );
            ++it;
        }
        delete l;

QObjectList *l = this->queryList( "TableButton" );    // get all its children which is TableButton
        QObjectListIt it( *l ); // iterate over the buttons

        while ( it.current() != 0 )
        {
            // for each found button...
            ((TableButton *)(it.current()))->close( TRUE );
            ++it;
        }
        delete l;

To copy to clipboard, switch view to plain text mode 

Thanks!

foreach(TableButton *tb, findChildren<TableButton*>())
    tb->close(TRUE);

foreach(TableButton *tb, findChildren<TableButton*>())
    tb->close(TRUE);

Shorter than before, right?
