[ka-Map-users] cellSize

[Paul Spencer]

Brent,

these values are available after ka-Map completes initialization.   
Initialization starts when you call

myKaMap.initialize();

and completes when you receive the KAMAP_INITIALIZED event or the  
KAMAP_MAP_INITIALIZED event.  This is because initialization happens  
asynchronously using an XmlHttpRequest call to a server side script,  
init.php, to perform initialization.

so to get the cellsize, you would do the following:

myKaMap = new kaMap( 'viewport' );
myKaMap.registerForEvent( KAMAP_INITIALIZED, null, myInitialized );

function myInitialized( )
{
     alert( myKaMap.cellSize );
}

Cheers

Paul
