How to create a Combo box in a Tablview Model

[uzairsaeed702]

Finally problem solved after reading again n again about MVC and thanks "All" for the support !!

I have configured the model with Combo box delegate with openPersistentEditor in combo box enabled columns (4,5) .

In ComboBoxDelegate.cpp

]QWidget *ComboBoxDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem & option , const QModelIndex &index ) const
{
 
 
    if(index.column() == 3 || index.column() == 4) 
{
 
        // Create the combobox and populate it
        QComboBox *cb = new QComboBox(parent);	
        cb->addItem(QString("Please Select"));
        cb->addItem(QString("1"));
        cb->addItem(QString("2"));
        cb->addItem(QString("3"));
        connect(cb, SIGNAL(currentIndexChanged(QString)), this, SLOT(print(QString)));
        return cb;
    } else
        return QStyledItemDelegate::createEditor(parent, option, index);
}

]QWidget *ComboBoxDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem & option , const QModelIndex &index ) const
{


    if(index.column() == 3 || index.column() == 4) 
{
      
        // Create the combobox and populate it
        QComboBox *cb = new QComboBox(parent);	
        cb->addItem(QString("Please Select"));
        cb->addItem(QString("1"));
        cb->addItem(QString("2"));
        cb->addItem(QString("3"));
        connect(cb, SIGNAL(currentIndexChanged(QString)), this, SLOT(print(QString)));
        return cb;
    } else
        return QStyledItemDelegate::createEditor(parent, option, index);
}

And in my TableModel.cpp Class

]
bool TableModel::setData(const QModelIndex & index, const QVariant &value, int role)
{
	int row = index.row();
	int col = index.column();
	QMap<QString, QString> qMapPair = listOfItems.at(index.row());
 
 
	if(index.isValid() && role == Qt::EditRole)
	{
		switch(col) {			
		case 3 :
			{
				qDebug() << "Value From Table Model = " <<value.toString() << "Row" <<row << "xCol"<< col ;
				return true;
			}
			break;
			case 4 :
			{
				qDebug() << "Value From Table Model = " <<value.toString() << "Row" <<row << "xCol"<< col ;
				return true;
			}
			break;
		default :
			break;}}return false;}

]
bool TableModel::setData(const QModelIndex & index, const QVariant &value, int role)
{
	int row = index.row();
	int col = index.column();
	QMap<QString, QString> qMapPair = listOfItems.at(index.row());


	if(index.isValid() && role == Qt::EditRole)
	{
		switch(col) {			
		case 3 :
			{
				qDebug() << "Value From Table Model = " <<value.toString() << "Row" <<row << "xCol"<< col ;
				return true;
			}
			break;
			case 4 :
			{
				qDebug() << "Value From Table Model = " <<value.toString() << "Row" <<row << "xCol"<< col ;
				return true;
			}
			break;
		default :
			break;}}return false;}

and things are working perfectly , now i am working on a event that when i will select any index value in combo box it will populate a dialog which configure the data on my Map. I will ask later for further question .
