How to make text Bold of the Item selected with Checkbox in QT?

[Aviral 0]

I want to make checked Items in Bold Format in QT DOM Model.

QVariant DomModel::data(const QModelIndex &index, int role) const
{
    if (!index.isValid())
        return QVariant();

    DomItem *item = static_cast<DomItem*>(index.internalPointer());
    const QDomNode node = item->node();
    if ( role == Qt::CheckStateRole && (index.column() == 0) && hasChildren(index) )
        return static_cast< int >( item->isChecked() ? Qt::Checked : Qt::Unchecked );
    if (role != Qt::DisplayRole)
        return QVariant();

    switch (index.column()) {
        case 0:
            return node.nodeName();
        case 1:
        {
            const QDomNamedNodeMap attributeMap = node.attributes();
            QStringList attributes;
            for (int i = 0; i < attributeMap.count(); ++i) {
                QDomNode attribute = attributeMap.item(i);
                attributes << attribute.nodeName() + "=\""
                              + attribute.nodeValue() + '"';
            }
            return attributes.join(' ');
        }
        case 2:
            return node.nodeValue().split('\n').join(' ');
        default:
            break;
    }
    return item->data(index.column());
}

Flag Function

Qt::ItemFlags DomModel::flags(const QModelIndex &index) const
{
    if (!index.isValid())
        return Qt::NoItemFlags;
    Qt::ItemFlags flags = Qt::ItemIsEnabled | Qt::ItemIsSelectable;
    if ( index.column() == 0 )
        flags |= Qt::ItemIsUserCheckable;
    return flags;
}

setData Function

bool DomModel::setData(const QModelIndex &index, const QVariant &value, int role) {
    DomItem *item = static_cast<DomItem*>(index.internalPointer());

    if (index.column() == 0 ){
        if (role == Qt::EditRole) {
            return false;
        }
        if (role == Qt::CheckStateRole) {
            item->setChecked(value.toBool());
            emit dataChanged(index, index);
            return true;
        }
    }
    return QAbstractItemModel::setData(index, value, role);
}

@Aviral-0 said in How to Insert checkbox in root of Qtreeview. Treeview is created by using QDOMDocument reading XML file.:

@JonB You don't know anything, just arrogant rude. I didn't find any solutions to my problem from you!

So precisely what I explained to you to do.
