HTMLArea widget for Interchange


  [display type=fck name=foo height=NN width=NNN]




The C<fck> widget makes calls to FCKeditor, an excellent rich-text
editor that replaces a C<TEXTAREA> component on supported browsers. It
operates as a normal textarea otherwise.

Supported browsers include at least Mozilla 1.3.1 and higher, including
Firefox, and MSIE 6 and higher.


To install, get FCKeditor 2.1 or later and install in the C<fckeditor>
directory of your DocumentRoot. (That means that routines can be accessed
with a base HREF of C</fckeditor/>.

Alternatively, you can set the Interchange Variable FCKEDITOR_PATH to
the appropriate path.

This widget requires Interchange 5.0 and higher.

If you are planning on using it outside of the Interchange UI, you must
either have the output-style of layout (the "mike" demo) with a 
[scratch meta_header] call in the <HEAD> area, or you must place the
equivalent of the following in the header of any page to use this widget:

    [tmp tmp_hpath][either]__FCKEDITOR_PATH__[or]/fckeditor/[/either][/tmp]
	<script type="text/javascript">
	   _editor_url = "[scratch tmp_hpath]";
	<script type="text/javascript" src="[scratch tmp_hpath]fckeditor.js"></script>

The "en" is the language locale to use. If you use the output-style
layout, this is automatically determined from the Interchange locale.
You can also override this with the Variable FCKEDITOR_LANG.

=head1 BUGS

A bug in MSIE doesn't allow initialization of a textarea until the
complete document is loaded. This means that the editor toolbox will not
show up until the mouse enters the C<TEXTAREA>.
