How to move OpenLayers Vector programmatically?

Question

The API documentation for OpenLayers.Feature.Vector says that Vector itself has no methods at all.

I know how to let user move the Vector by adding OpenLayers.Control.DragFeature control to map. So if the user can move the Vector then there has to ba a way to move it programmatically too. But I can't figure out how to do it.

Answer 1

You move an OpenLayers.Feature.Vector object by calling methods on its geometry object, not the vector itself. These methods include move, rotate, resize, and transform.

Note that you will not find any of the methods defined on the OpenLayers.Geometry base object but only on the appropriate child object (note that there are multiple level of inheritance within OpenLayers geometries). OpenLayers.Geometry.Collection is a good example.

You can find a great example of programmatically moving OpenLayers vectors here .
