[Mapserver-users] Mapserver and flash

[Yewondwossen Assefa]

The way to do it is to use at a layer level a metadata called 
SWFDUMPATTRIBUTES. The value used for this metadata are the names of the 
attributes you want to export to the swf file. Please refer to section 
"How to configure the map file to export attributes"  and "Events and 
Highlights" in the document 
http://www2.dmsolutions.ca/mapserver/dl/FlashMapserverUserDoc.html

  Once the attributes are exported to the swf file, when the user clicks 
on these objects, there is a mouse event which is triggered and makes an 
Action Script call to: _root.ElementSelecetd(LayerId, ShapeId, Event). 
The Flash application who want to receive these events should define the 
function ElementSelected and use the information receive to do actions 
like retrieving the attribute values from the specific SWF for the 
specified shape and display it.
