Accessing check state of CheckBox in QTableWidget

[faldzip]

the program halts on a signal at that line

you mean you get segmentation fault? So check which of these many function calls in this line causes this seg fault. What item->column() returns?

[lnxusr]

Not a segfault, I get this:

ASSERT failure in QList<T>::operator[]: "index out of range", file /usr/include/qt4/QtCore/qlist.h, line 403

ASSERT failure in QList<T>::operator[]: "index out of range", file /usr/include/qt4/QtCore/qlist.h, line 403

when I try to use sender[6] to get the row and/or column.

This looks to me that ther is no sixth column in the table, but there is. I can force it to get column six by hardcodeing in a 6,

QCheckBox *mcb = qobject_cast<QCheckBox*>(m_ui->tableWidget->cellWidget(item->row(), 6));

QCheckBox *mcb = qobject_cast<QCheckBox*>(m_ui->tableWidget->cellWidget(item->row(), 6));

To copy to clipboard, switch view to plain text mode 

but I can't get column six using

QCheckBox *mcb = qobject_cast<QCheckBox*>(m_ui->tableWidget->cellWidget(item->row(), selected[6]->column()));

QCheckBox *mcb = qobject_cast<QCheckBox*>(m_ui->tableWidget->cellWidget(item->row(), selected[6]->column()));

To copy to clipboard, switch view to plain text mode 

Why!?

Had to wrap the Assert in code or the second colon after QList<T> showed up as a smilie..
