[fusion-users] Mapguide Eventhandling with Fusion.

[Paul Deschamps]

Did you add this in map.js or your supporting application JS file in the
template? doing so would probably fire it in the manor of which you
described. 


In the application template the supporting JS should have: 

window.onload = function(){
  Fusion.initialize();
  Fusion.registerForEvent(Fusion.Event.FUSION_INITIALIZED,
onInitialize);
}

// funsion initialized fire listeners. 
function onInitialize() {
    // get the mapwidget via ID
    var map = Fusion.getMapById('mapArea'); 
    map.registerForEvent(Fusion.Event.MAP_LOADING, mapLoading);
    map.registerForEvent(Fusion.Event.MAP_LOADED, mapIsLoaded);
    map.registerForEvent(Fusion.Event.MAP_RELOADED, mapReloaded);
    map.registerForEvent(Fusion.Event.MAP_ACTIVE_LAYER_CHANGED,
activeLayerChanged);
    map.registerForEvent(Fusion.Event.MAP_SELECTION_ON, selectionOn);
}

// console.log requires  firebug. see. http://www.getfirebug.com/
function mapLoading(){
  console.log("MAP_LOADING");


function mapIsLoaded(){
  console.log("MAP_LOADED");
}

function mapReloaded(){
  console.log("MAP_RELOADED");
}

function activeLayerChanged(){
  console.log("MAP_ACTIVE_LAYER_CHANGED");
}

function selectionOn(){
  console.log("MAP_SELECTION_ON");
}

Hope this helps

Cheers
