=head1 NAME

  DBIx::HTMLView::Text - A multi line string filed



=head1 SYNOPSIS

  $fld=$post->fld('testf');
  print $fld->view_html;

=head1 DESCRIPTION

This is a subclass of DBIx::HTMLView::Str used to represent larger
texts. The main difference from a Str is that the default edit_html
editor uses a <textarea>...</textarea> construct instead of an 
<input ...> tag.

This fld also has two parameters that are specified in the $data hash
passed to the constructor (see the DBIx::HTMLView::Fld manpage). They
are 'width', the width of the <textarea> editor in characters
(defaults is 80) and 'height', the height of the <textarea> editor in
characters (default is 50).

Except for the methods described in the superclasses
(DBIx::HTMLView::Fld, DBIx::HTMLView::Field, DBIx::HTMLView::Str)
there are also the following methods.
