No.  That's intented behaviour.  (hint: accessibility -- the current
selection should always be clearly visible)

As I understand it, you probably want to handle rows with subnodes as a
whole (like e.g. copying a directory).  That's OK, and should be easy
enough to handle programatically.

See Gtk::TreeView::get_path_at_pos() (you need to pass the coordinates
from the event struct to this method).
