QTableView header invisible

[squidge]

I assume your setting columnCount? Heres a snippet from my model that works:

int TableDetailModel::columnCount(const QModelIndex &parent) const
{
    Q_UNUSED(parent);
    return 2;
}
 
QVariant TableDetailModel::headerData(int section, Qt::Orientation orientation, int role) const
{
    if (role != Qt::DisplayRole)
        return QVariant();
 
    if (orientation == Qt::Horizontal) {
        switch (section) {
            case 0:
                return tr("Id");
 
            case 1:
                return tr("Description");
 
            default:
                return "Unknown!";
        }
    }
    return QVariant();
}

int TableDetailModel::columnCount(const QModelIndex &parent) const
{
    Q_UNUSED(parent);
    return 2;
}

QVariant TableDetailModel::headerData(int section, Qt::Orientation orientation, int role) const
{
    if (role != Qt::DisplayRole)
        return QVariant();
    
    if (orientation == Qt::Horizontal) {
        switch (section) {
            case 0:
                return tr("Id");
                
            case 1:
                return tr("Description");
                
            default:
                return "Unknown!";
        }
    }
    return QVariant();
}
