have you considered using a delegate instead? Most of the

delegate for something.

Yes, that sort of works.  I told IB to delegate from the TableView
to MyWindowController and tried the following test code:

  sub tableViewSelectionDidChange
  {
    my ($self) = @_;

    NSLog('row selected');
    NSLog($self->selectedRow());

    return $self;
  }

The "row selected" message shows up when I click on a row, but then
I see the following:

2003-01-29 18:26:58.313 Morinfo[16919] Perl error: Can't locate object
  method "selectedRow" via package "MyWindowController" at
  .../MyWindowController.pm line 68.

Right, because you get back self as the first parameter to the sub, since it's being done as a method call. The second parameter should be the tableview, so the code would look like:

sub tableViewSelectionDidChange {
my ($self, $tableview) = @_;
NSLog("Row selected " . $tableview->selectedRow());
return $self;
}
