Chip,

I've got a set of DHTML tools I created using VML on IE.  My whole
application is IE-centric at the moment so I'm not even sure if other
browsers support VML.  I assume I'll have to scrap it all when I try to make
this thing cross-browseable.  VML was just so easy.

I looked at your site and I had a hard time pulling out the DHTML stuff that
actually makes the boxes.  Could you give me a hint on what mechanisms
you're using to do this.  And, are you trying to develop one set of tools to
use with both mapserv and mapscript applications?  I'm not using mapscript
(yet) but need to develop cross-browser dhtml stuff.

Thanks,

Adam Ryan

Subject: [Mapserver-users] DHTML Navigation Tools for MapScript

I'm interested in working with folks to develop a set of DHTML based
navigation tools for use (mainly) with MapScript. Sort of a DHTML version of
Rosa. I've done some preliminary work on this, and posted an example
application that uses it at the following URL:

http://www.gasai.com/gisapps/world/

The chief features are:

 - works in IE and Mozilla/Netscape
 - 'rubber band' style zoom controls
 - click-n-drag panning

This initial effort is a combination of some code I borrowed from Puneet
Kishor, and ideas gained from looking at Steve Lime's DHTML Land View
application. Basically, the application relies pretty heavily on the CBE
tools to bridge the differing IE<->Mozilla event models.

I started down this path b/c I was running into Java issues in various
browsers... and thought maybe the DHTML route might simplify things. I'm not
entirely convinced that this is true.

Anyway... my idea, if anyone thinks this is a worthwhile endeavor, is to try
to refine this into a more simplistic 'plug-in' that can be used in
MapServer applications. However, I have absolutely no experience working
'collectively' with others to develop software (like with CVS). 

Is this the sort of thing that would be amenable to working collectively on?
Is anyone interested? How would we set it up?

TIA!

Chip Hankley
