No, you're not asking nonsense. My previous answer was nonsense. But
there is also a clean way to achieve what you want using several
contexts. For the zoom/pan (called area of interest), you can use the
existing ZoomToAoi tool. If your master map (the one that controls the
viewport of the others has a context model with id "mainMap", you
would have to add the following under the <tools> section of your
other models:
<ZoomToAoi id="separateIdForEachContextHere">
<targetModel>mainMap</targetModel>
</ZoomToAoi>
This will listen to the aoi event, and will synchronize the maps
without pressing a button. If you do not want this, copy this tool and
remove the listener for the aoi event.
For synchronizing the layers, create a tool similar to the above with
a method that looks something like this:
var masterLayers = objRef.targetModel.getAllLayers();
var name, hidden;
for (var i=0; i<masterLayers) {
name = getNodeValue("wmc:Name");
hidden = objRef.targetModel.getHidden(name);
objRef.model.setHidden(name);
}.
The above assumes that you want to synchronize when you click a
button. If you want to synchronize automatically when changing layer
visibility in the master map, it is even simpler:
this.syncHidden = function(objRef);
var layer = objRef.model.getParam("hidden");
objRef.model.setHidden(layer);
}
this.targetModel.addListener("hidden", this.syncHidden, this);
Regards,
Andreas.
