[fusion-users] Mapguide Eventhandling with Fusion.

[Paul Spencer]

Tómas,

these are not the droids you are looking for!  These events only  
relate to loading the map definition from the server, not drawing the  
map.  You want Fusion.Event.MAP_BUSY_CHANGED.  This gets called when  
the map starts drawing and again when it is finished, but you need to  
check map.isBusy to see if the map is still busy or not because  
several busy states can be queued up.

Cheers

Paul
