How to set tableView headers with QStandardItemModel ?

imene

Hello;
I want to set tableView header with QStandardItemModel ?

mModel->setColumnCount(3);
    mModel->setHeaderData(0, Qt::Horizontal, "Header 1", Qt::DisplayRole);
    mModel->setHeaderData(1, Qt::Horizontal, "Header 2", Qt::DisplayRole);
    mModel->setHeaderData(2, Qt::Horizontal, "Header 3", Qt::DisplayRole);
    QHeaderView * p = new QHeaderView(Qt::Orientation orientation,(m_ui->Table_CSV));
    p->setModel(mModel);
    m_ui->Table_CSV->setHorizontalHeader(p);
    m_ui->Table_CSV->show();
    m_ui->Table_CSV->horizontalHeader()->setModel(mModel);

The problem is here:

 QHeaderView * p = new QHeaderView(Qt::Orientation orientation,(m_ui->Table_CSV));

If the model returns data for the headers then the default QTableView will use those and there is no need to create your own QHeaderView, just set the model on the view. In most cases this is adequate.

    QStandardItemModel *model = new QStandardItemModel(3, 3, this);
    model->setHeaderData(0, Qt::Horizontal, "C 1", Qt::DisplayRole);
    model->setHeaderData(1, Qt::Horizontal, "C 2", Qt::DisplayRole);
    model->setHeaderData(2, Qt::Horizontal, "C 3", Qt::DisplayRole);
    model->setHeaderData(0, Qt::Vertical, "Row 1", Qt::DisplayRole);
    model->setHeaderData(1, Qt::Vertical, "Row 2", Qt::DisplayRole);
    model->setHeaderData(2, Qt::Vertical, "Row 3", Qt::DisplayRole);
    for (int r = 0; r < 3; ++r ) {
        for (int c = 0; c < 3; ++c) {
            model->setData(model->index(r, c), QString("R%0C%1").arg(r).arg(c));
        }
    }
    ui->tableView->setModel(model);

You may subclass QHeaderView if you need some custom rendering. In that case you just set the customised header view on the table view and it inherits the correct model.

    CustomHeaderView *hv = new CustomHeaderView(Qt::Horizontal, this);
    ui->tableView->setHorizontalHeader(hv);
