Reading Value from a QTablewidget

deleted543

I have a Qtable widget where I want to extract the value in one of the cells, and then make a series of calculations. I will then enter the result of that calculation in another cell.

I cannot seem to find any way to extract a value from the table.

I use thefollowing:

QTableWidgetItem *madeItem = ui->tableWidget->item(0,4);

The program then stops at this point in qtablewidget.h.

inline QString text() const
    { return data(Qt::DisplayRole).toString(); }
inline void setText(const QString &text);

What am I missing?

Hi and welcome

madeItem

and its not NULL ?

And everything is setup correctly ? with row,col count ?

If you reference invalid cell ( empty as no item assigned) that would result in something like that.

ui->tableWidget->model()->index(0,4).data(); this returns a QVariant
