[mapguide-users] Modify layout and layer on map

[Kenneth Skovhede, GEOGRAF A/S]

Take a look at this page, it shows how to modify the map before it loads:
http://trac.osgeo.org/mapguide/wiki/maestro/MaestroAPI/samples/AddInitialLayer

I think it's pretty close to what you want.
It is using the MaestroAPI, which is a bit different from the official 
API, but the general idea is the same.

On this page you can see how to modify the layer filter, after the map 
has loaded:
http://trac.osgeo.org/mapguide/wiki/maestro/MaestroAPI/samples/ModifyLayerFilter

General documentation for the MaestroAPI is here:
http://trac.osgeo.org/mapguide/wiki/maestro/MaestroAPI
