Thank you for your reply. I am using the former approach.

I also want to keep a track of which column of the row is clicked. For
the slot connected to TreeView::signal_row_activated() which had
arguments (const Gtk::TreeModel::Path& path, Gtk::TreeViewColumn*
col), I was able to get the column clicked using 'col' here.

Taking TreeSelection::signal_changed(), since the associated slot does
not take any arguments, what can be the method to get the column of
the selected row on which mouse was clicked?
