I like to use $ev->{button} == 1 to insure that the double click was a
left mouse button double click.

sub select_data {
        my ($clist, $ev) = @_;

        if ($ev->{button} == 1 and $ev->{type} eq '2button_press') {
                my ($row, $col) =
                        $clist->get_selection_info($ev->{x},$ev->{y});
                #do stuff with that row/column.
        }
}
