Re: unable to call a method reference with an argument

I think the $self->{contents} IS being passed, but is not consumed in the anon sub.

Try:

$self->{txt_box}=txt_box->new(
   $self->{frm}, 
   sub {$self->updt(@_)} # Pass incoming parms along.
);

The (@_) in "sub {$self->updt(@_)}" worked perfectly. I did try () and ('') to try to force recognition of a single parameter prototype but that didn't work at all and I "solved" the problem by just getting hold of self->(txt_box)->{contents} but wanted to know how to do this for when I can't get at things that way. Thank you very much indeed.	[reply]
