How to know if selection is valid

8 years 6 months ago #1 by Pascal
How to know if selection is valid was created by Pascal
I have below code:
    Qtitan::GridTableView* view = ui->gridSites->view<Qtitan::GridTableView>();
    GridSelection* selection = view->selection();

    if (selection) {
        QModelIndex idIndex = m_pSiteTableModel->index(selection->row()->modelRowIndex(),SiteTableModel::id);
        .... 
   }
In some cases selection->row() causes an exception (eg empty grid model, grid is filtered and no rows)

How can I verify selection is valid ?

Thanks
