[fusion-users] Fusion + MapServer Function/Look Like MapGuide

[Paul Spencer]

It should be possible :)  You will need to spend some quality time  
with firebug probably, but in essence you can get access to the  
OpenLayers.Map instance and then do whatever you want.  I would  
probably approach it like this:

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

function fusionError(eventId, error) {
   console.log('Fusion Error: '+error.toString();
}

function fusionInitialized(eventId) {
     var map = Fusion.getWidgetById('Map'); // the id of the div  
containing the map
     var olMap = map.oMapOL;
     var wms = new OpenLayers.Layer.WMS(/* parameters */);
     olMap.addLayer(wms);
}

You will probably run into difficulty with the whole baseLayer thing  
in OpenLayers.  By default, most tile-based layers want to be base  
layers and you need to add isBaseLayer: false to the layer options  
(4th arg to WMS layer, might be different in other layer types).

You can also start Fusion without a map loaded and inject a baseLayer  
using this method, but then a whole bunch of things won't really work  
- for instance a lot of widgets only get enabled after a map has loaded.

Some feedback on *how* this should work would be appreciated.  If you  
have a particular use case and would like to be able to set things up  
in a particular way, that would be very useful to the developers as we  
plan out exposing more OpenLayers stuff.

Cheers

Paul
