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);
}

The QAbstractItemModel::rowsAboutToBeRemoved() signal gives you in parameter the parent index and the row of removed object.
So you can connect that to your proper slot outside the treeview and decide to call clearSelection() (it is a public slot) or not following tests on removed rows.

No ?

But I'm not afraid about subclassing QTreeView, anyway...
