Refreshing QTableView selection manually

[Lefix2]

Hello,
I have a probleme with a qTableview.
I have two widgets, a qCustomPlot and a qTableView between wich selections signals are sent.
For the uses of my application, i was forced to blockSignal on my SelectionModel's TableView and modify the selection manually.
But, when i select my indexes, if there is no scroll, the olds selected lines doesn't deselect until user get focus on qTableView or until the QTableView is resized/scrolled.
I tried update(), repaint() and show() on mys tableView but nothing changed! :/

Here is the code:

void OSGM::onGraphSelectionChanged(int index)
{
    auto selectionModel = m_TableView.selectionModel();
    QItemSelection selection;
    selectionModel->blockSignals(true);

        // if it's a selection
        if (index != OSGEH::ELEMENT_DESELECTED) {
            // create the selection manually
            auto keys = m_TabRectMap.keys(index);

            for (auto key : keys) {
                auto row = m_TableView.model()->index(key, 0);
                selection.append(QItemSelectionRange(row, row));
            }
        }
        selectionModel->select(selection, QItemSelectionModel::Current | QItemSelectionModel::Rows);
    
     selectionModel->blockSignals(false);

    if (selection.size() != 0) 
    {
        // scroll qtableview to the first item
        m_TableView.scrollTo(selection.at(0).bottomRight(),QAbstractItemView::PositionAtTop);
    }
    m_TableView.show();
}

Hi and welcome to devnet,

Why do you need to call blockSignals ?
