[Chameleon] What does chameleon do?

[Julien-Samuel Lacroix]

Hi,

The Table widget can be what you need. Instead of showing the restairant 
name in the map, where they have a chance to overlap, you put them into 
a table below the map. Look at the documentation 
(http://www.maptools.org/chameleon/wiki/Table). Plus, I'm not sure its 
in the documentation, but the Table widget create a SharedResource 
containing all the element included in it's body. This shared resource 
is called from the named of the one used in the Table and add "_IMAGE" 
at the end. So if your shared resource is called "MyResult", the shared 
resource outputed from the Table will be "MyResult_IMAGE". If you use 
this one in the MapImageSharedResource, you will be sure that your map 
don't show more information than the table show. And in the table you 
will be able to show all the fields you want from the table. However if 
you want to match each record i the table its dot in the map you can use 
number in your table and in your map.

Hope this will help.

Best regards,
Julien
