QTableWidget - problem when editing multiple items

[xportation]

Thanks norobro, it works fine and I'm using it.
I have tested another way by making this little "good blood" hack:

class MyTableWidgetItem : public QTableWidgetItem
{
public:
	explicit MyTableWidgetItem(const QString & text, int type = Type) : QTableWidgetItem(text, type) {}
 
	virtual void setData(int role, const QVariant &value)
	{
		if (QAbstractTableModel *model = (this->tableWidget() ? qobject_cast<QAbstractTableModel*>(this->tableWidget()->model()) : 0)) {
			model->blockSignals(true);
			QVariant nullValue;
			QTableWidgetItem::setData(role,nullValue);
			model->blockSignals(false);
		}		
		QTableWidgetItem::setData(role,value);
	}
};
 
//--
 
QTableWidgetTest::QTableWidgetTest(QWidget *parent, Qt::WFlags flags)
	: QDialog(parent, flags)
{
	ui.setupUi(this);
 
	int value= 0;
	for (int row= 0; row < table->rowCount(); row++) {
		for (int col= 0; col < table->columnCount(); col++) {
			QTableWidgetItem *item= new MyTableWidgetItem(QString::number(value));
			table->setItem(row,col,item);
			value++;
		}
	}	
 
	connect(ui.tableWidget,  SIGNAL(itemChanged(QTableWidgetItem*)), this,  SLOT(multipleItemsChanged(QTableWidgetItem*)));
}

class MyTableWidgetItem : public QTableWidgetItem
{
public:
	explicit MyTableWidgetItem(const QString & text, int type = Type) : QTableWidgetItem(text, type) {}
	
	virtual void setData(int role, const QVariant &value)
	{
		if (QAbstractTableModel *model = (this->tableWidget() ? qobject_cast<QAbstractTableModel*>(this->tableWidget()->model()) : 0)) {
			model->blockSignals(true);
			QVariant nullValue;
			QTableWidgetItem::setData(role,nullValue);
			model->blockSignals(false);
		}		
		QTableWidgetItem::setData(role,value);
	}
};

//--

QTableWidgetTest::QTableWidgetTest(QWidget *parent, Qt::WFlags flags)
	: QDialog(parent, flags)
{
	ui.setupUi(this);
	
	int value= 0;
	for (int row= 0; row < table->rowCount(); row++) {
		for (int col= 0; col < table->columnCount(); col++) {
			QTableWidgetItem *item= new MyTableWidgetItem(QString::number(value));
			table->setItem(row,col,item);
			value++;
		}
	}	
	
	connect(ui.tableWidget,  SIGNAL(itemChanged(QTableWidgetItem*)), this,  SLOT(multipleItemsChanged(QTableWidgetItem*)));
}
