Subj : ANNOUNCE: CGI::Explorer V 1.10
To   : All
From : Ron Savage
Date : Mon Mar 12 2001 01:51 pm

From: "Ron Savage" <ron@savage.net.au>

This pure Perl module is available from CPAN and from my web site.

What it is:
CGI::Explorer is a support module for CGI scripts. It manages a tree of data, 
so that the script can display the tree, and: 1) the user can click on a node 
in the tree to open or close that node, and which selects the node and submits 
the form, and which toggles the open/closed status of that node, or 2) the user 
can click on the text beside the node, which selects the node and submits the 
form, but does not change the open/closed status of that node.

A demo, ce.pl, is provided.

Changes (V 1.00 to 1.10):

1.10  Sat Mar 11 14:00:00 2001
 - Change
  use CGI qw/fieldset legend/;
  to
  use CGI;
  in Explorer.pm. These methods are only used by ce.pl.
 - Add method image($icon_id, $new_image) to allow setting the image file name
  of any icon. See POD for a list of icon ids.
 - Add constructor option css to set the style-sheet for submit buttons.
  A default style-sheet is provided. Yes, I know the submit button text,
  using the style-sheet, is really too wide, but as you'll see from the source,
  I cannot find a style-sheet command to make it narrower.
 - Add method css() to set or retrieve the style-sheet. As with other new()
options,
  you can also use method set(css => $new_css) to set the style-sheet after
  construction.
 - Rename constructor option from 'a_href' to 'click_text', since I now use
  submit buttons and not a hrefs. The default for click_text is 1,
  whereas for a_href it was 0.
  Specifically, new(click_text => 1) has the effect of making the text
  (node id and/or name) [to the right of the node] into a submit button,
  formatted nicely via the css option. Clicking this text submits the form
  and sets the current node. But, if the node has children, it does not change
  the open/closed status of the node, whereas clicking on the node icon toggles
  the status.
 - Remove restriction that there had to be a node id == 1.
 - Ship explorer_server.gif and explorer_server.png for variety, and for use
  within ce.pl.
 - Various minor changes to the docs.
