Qt4 QTableView and checkbox click event

Question

I have created QTableView and add an QStandardItem checkbox into with this code:

....
QStandardItem *chkItem = new QStandardItem(true);
chkItem->setCheckable(true);
chkItem->setData(Qt::AlignCenter, Qt::TextAlignmentRole);
tblModel->appendRow(chkItem);
...

where tblModel is QStandardItemModel.

Now i wonder how can i catch the checkbox changed state event?

I have tryed catch the table click event but this is triggered every times user click on a cell (i have no idea to know whether the checkbox state has changed or not). Please give me a way to solve this problem.

Try QStandardItem::checkState() to retrieve the Qt::CheckState of the checkbox. If you need to know, if the state changed, then save the old state somewhere and check if the state changed on the click event.
