clear all overlays about gwt-maps-v3-api HOT 2 CLOSED

bhamid,

There is no method like that. The methods on the Maps Javascript API have no such method. The issue here is that you add overlay items to a map using the setMap() method of the overlay, rather than something like map.addOverlay(overlay). So, even it we added a list of non-removed overlays inside the MapWidget class, we would not know what is on the map, since they are not added that way.

Typically you would work around this by keeping a tracking array, list, or map of the things you've added to the map and adding/removing them from the tracking list as you add/remove them from the map. This way you can write a clear() method that just runs down this list and clears everything off the map. That is how I've done this in my apps.
