TreeView::set_cursor() should do this. There are three versions of that
method, depending on how precise you want to be:

This should be possible, and I guess someone has achieved it. I might like
the same feature in Glom.

But do remember that this might interfer with the standard keyboard
navigation used for acccessibility.
