Which signal to use when table item is checked

[zolookas]

Hi, I am using QTableWidget and I am creating table items like this:

QTableWidgetItem *cgname = new QTableWidgetItem(desc);

QTableWidgetItem *cgname = new QTableWidgetItem(desc);

To copy to clipboard, switch view to plain text mode 

then i set it checked:

cgname->setCheckState(Qt::Checked);

cgname->setCheckState(Qt::Checked);

To copy to clipboard, switch view to plain text mode 

and intset to table

cgTableWidget->setItem(row, 0, cgname);

cgTableWidget->setItem(row, 0, cgname);

To copy to clipboard, switch view to plain text mode 

I want to modify some data when checkbox becomes checked/unchecked, so i probably need to use some signal for this, but which one? I have looked at QTableWidgetItem documentation and have not found it Hope you can help me.
