I've done something similiar with GTK_SELECTION_MULTIPLE - I use
shift-click to select from the last selected row all the way to the
current row.  I call gtk_signal_emit_by_name with each row I want to
select to force a call to the callback for each row.  There may be a
better way to do this, but I didn't look into it once I got this to
work.
