Hi,

QCLDelegate::QCLDelegate(QObject *parent)
    : QItemDelegate(parent)              
{                                        
}                                        
 
QWidget *QCLDelegate::createEditor(QWidget *parent,
                                     const QStyleOptionViewItem & /* option */,
                                     const QModelIndex &index) const           
{                                                                              
    QComboBox *comboBox = new QComboBox(parent);                               
    if (index.column() == 2) {                                                 
        for(int i = 1970; i < 2014 ; i++){                                     
                QVariant v(i);                                                 
                comboBox->addItem(v.toString());                               
        }

        comboBox->addItem(tr("Blu-Ray"));
        comboBox->addItem(tr("Other"));
    } else if (index.column() == 4) {
        comboBox->addItem(tr("Yes"));
        comboBox->addItem(tr("No"));
    }
    connect(comboBox, SIGNAL(activated(int)), this, SLOT(emitCommitData()));
 
    return comboBox;
}

QCLDelegate::QCLDelegate(QObject *parent)
    : QItemDelegate(parent)              
{                                        
}                                        

QWidget *QCLDelegate::createEditor(QWidget *parent,
                                     const QStyleOptionViewItem & /* option */,
                                     const QModelIndex &index) const           
{                                                                              
    QComboBox *comboBox = new QComboBox(parent);

    } else if (index.column() == 3) {
        comboBox->addItem(tr("BRRip"));
        comboBox->addItem(tr("DVDRip"));
        comboBox->addItem(tr("Blu-Ray"));
        comboBox->addItem(tr("Other"));
    } else if (index.column() == 4) {
        comboBox->addItem(tr("Yes"));
        comboBox->addItem(tr("No"));
    }
    connect(comboBox, SIGNAL(activated(int)), this, SLOT(emitCommitData()));

    return comboBox;
}

To copy to clipboard, switch view to plain text mode 

and here is how i add to the table widget

bool QCLMovies::parseElements(QDomNode &c, int row)
{
    while(!c.isNull()){
        QDomElement k = c.toElement();
        if(k.text().isEmpty())
            return false;
        if(labels.indexOf(k.tagName()) == -1)
            return false;
       //Adding to table widget
        setItem(row, labels.indexOf(k.tagName()), new QTableWidgetItem(k.text()));
        c = c.nextSibling();
    }
 
    return true;
}

bool QCLMovies::parseElements(QDomNode &c, int row)
{
    while(!c.isNull()){
        QDomElement k = c.toElement();
        if(k.text().isEmpty())
            return false;
        if(labels.indexOf(k.tagName()) == -1)
            return false;
       //Adding to table widget
        setItem(row, labels.indexOf(k.tagName()), new QTableWidgetItem(k.text()));
        c = c.nextSibling();
    }

    return true;
}

To copy to clipboard, switch view to plain text mode 

the class declaration is QCLMovies: public QTableWidget

I am trying to read an XML file into the QTableWidget, with columns 2,3 and 4 as combo boxed and columns 0 and 1 as Qtablewidgetitem (QString), but when i start the application it shows all combo boxes..

Please help me out

Thanks
