How to add multiple icons to TreeItems of QAbstractTreeModel

[summit]

This is my current code i am only able to insert only one icon to the treeItem.

How can i add both the icons to the treeItem

QVariant TreeModel::data(const QModelIndex &index, int role) const
{

    if (!index.isValid())
        return QVariant();

    TreeItem *item = getItem(index);
    if (item)
    {
        switch (role)
        {
            case Qt::DisplayRole: case Qt::EditRole:
                return QString::fromStdString(item->data().GetName());
                break;
            case Qt::DecorationRole:
            {                           
                Container *cont = item->GetContainer();
                if (cont->GetGeometry()->isValid())
                {                           
                    QString qstrIconName =  cont->GetGeometry()->GetType().c_str();
                    QString qstrIconPath = QCoreApplication::applicationDirPath();
                    QPixmap pixmap;
                    QIcon icon;                 
                    qstrIconPath = qstrIconPath + "/Icons/" + qstrIconName + ".png";
                    pixmap.load(qstrIconPath);
                    icon.addPixmap(pixmap, QIcon::Normal, QIcon::On);               
                    return icon;
                }
                 // Function returns from here since we have returned the icon
                 // How can i add next icon to the same tree item

                int numberOfFunctions = cont->getNumberOfFunctions();
                if (numberOfFunctions > 0)
                {
                    QString qstrIconName = "FUNCTION";
                    QString qstrIconPath = QCoreApplication::applicationDirPath();
                    QPixmap pixmap;
                    QIcon icon;
                    qstrIconPath = qstrIconPath + "/Icons/" + qstrIconName + ".png";
                    pixmap.load(qstrIconPath);
                    icon.addPixmap(pixmap, QIcon::Normal, QIcon::On);
                    return icon;
                }
                break;              
            }
        }       
        return QVariant();
    }
}

@summit
I assume that DecorationRole only allows for one icon? I don't know how generically you would expect multiple icons to be accepted/displayed?

[summit]

@JonB Yes lot of time i would expect multiple icons to be displayed , what are the other ways i can achieve this ?

[JonB]

@summit
I will be silent after this, to allow another who knows better than I to help you, but I would assume you must look at QStyledItemDelegate as your way of displaying non-standard things like multiple icons, instead of going via Decoration role.

@summit

1. Add one column for every icon.
2. Create a big size icon that contains several icons in a row.
3. Write custom item delegate, draw in your own way.
