QTreeView: selection behavior upon selected item removal

[Pieter from Belgium]

I have solved it this way in my QTreeView subclass, but there must/ought to be a way for doing this by configuring Qt objects.

void TreeView::rowsAboutToBeRemoved ( const QModelIndex & parent, int start, int end )
{
   if (selectionMode() == QAbstractItemView::SingleSelection)
   {
      QModelIndexList selectedRows = selectionModel()->selectedRows();
      if (selectedRows.size() == 1 && selectedRows[0].parent() == parent && selectedRows[0].row() >= start && selectedRows[0].row() <= end)
      {
         // the rows about to be removed contain the single selected item
         selectionModel()->clear();
      }
   }
   QTreeView::rowsAboutToBeRemoved (parent, start, end);
}

void TreeView::rowsAboutToBeRemoved ( const QModelIndex & parent, int start, int end )
{
   if (selectionMode() == QAbstractItemView::SingleSelection)
   {
      QModelIndexList selectedRows = selectionModel()->selectedRows();
      if (selectedRows.size() == 1 && selectedRows[0].parent() == parent && selectedRows[0].row() >= start && selectedRows[0].row() <= end)
      {
         // the rows about to be removed contain the single selected item
         selectionModel()->clear();
      }
   }
   QTreeView::rowsAboutToBeRemoved (parent, start, end);
}
