I'm using QTableView and QStandardItemModel to show some data.

For each row, there is a column which has a check Box, this check box is inserted by setItem, the code is as follows:

int rowNum;
QStandardItemModel *tableModel;
QStandardItem* __tmpItem = new QStandardItem();

__tmpItem->setCheckable(true);
__tmpItem->setCheckState(Qt::Unchecked);

tableModel->setItem(rowNum,0,__tmpItem);

Now I want to interact with the check box. If a check box changes its state by user (from checked to unchecked or vice versa), I want to do something on the corresponding data row.

I know I can use signal-slot to catch the change of checkbox, but since there are lots of data row, I don't want to connect each row one by one.

Is there anyway to interact with the check action more effectively? Thanks :)
