scrolling in QTableWidget

[Ursa]

Hello!
I have two QTableWidget controls in my dialog. There are equal amount of records in the tables. I would like to synchronize scrolling in these controls - so when I scroll one table I get the same result in another one. Could you give me an idea?

Thanks in advance.

Provided that dimensions are same, it should be as simple as connecting scrollbars' valueChanged(int) signals to setValue(int) slots:

// establish connections in both directions
connect(table1->horizontalScrollBar(), SIGNAL(valueChanged(int)), table2->horizontalScrollBar(), SLOT(setValue(int)));
connect(table2->horizontalScrollBar(), SIGNAL(valueChanged(int)), table1->horizontalScrollBar(), SLOT(setValue(int)));
// ...and the same for vertical scroll bar

// establish connections in both directions
connect(table1->horizontalScrollBar(), SIGNAL(valueChanged(int)), table2->horizontalScrollBar(), SLOT(setValue(int)));
connect(table2->horizontalScrollBar(), SIGNAL(valueChanged(int)), table1->horizontalScrollBar(), SLOT(setValue(int)));
// ...and the same for vertical scroll bar

To copy to clipboard, switch view to plain text mode

Thanks for help. But I get another problem
It seems to me everything should be all right but I use this construction and get an error:
C2664: 'bool QObject::connect(const QObject *,const char *,const QObject *,const char *,Qt::ConnectionType)' : cannot convert parameter 1 from 'QScrollBar *' to 'const QObject *'
I use Win XP, QT 4.3.

Perhaps a missing #include <QScrollBar> ?
