[Qt-interest] TableWidget cellChanged(r,c) of nonexistend item ??

[Matthias Pospiech]

I have the following slot, called at cellChanged(int row, int column ).



void DialogGratingPeriodVariation::On_tableWidgetDevices_cellChanged(int 
row, int column )
{
    if (CouplerSetupList.size() == 0)
        return;
    if (column = 1)
    {
        QTableWidgetItem * item = tableWidgetDevices->item(row, column);
        CouplerSetupList[row].Description = item->text();
...

This is called at startup at the creation

        newItem = new QTableWidgetItem(buffer);
        tableWidgetDevices->setItem(i, 0, newItem);

However it crashes because the item pointer is 0.

What am I doing wrong?
