    i have a tree view and wanna know whether the first index is selected.
    if i do

    auto lst = TreeView->selectionModel()->selectedIndexes();
    if (lst.front() == TreeView->model()->index(0, 0))
    {
         // doesn't reach here because operator== of QModelndex compares the corresponding models too
    }
    

    what can i do?

      Does this work?

      TreeView->selectionModel()->isSelected( TreeView->model()->index(0, 0) )
