Listeners for zoom and pan on an openlayers map

Hello everyone,

I’d like to listen to the OL events, which are fired, when I zoom or pan on an OL map.
I want to add extra functionalities, if the user zooms or pans. So I need a listener for these events.
Is there any way with the OpenLayers Wrapper Addon for Vaadin or do I have to implement this on myself?

I’ve seen an approach with

but I don’t think it’s implemented in the Addon, is it?

Thanks a lot!

Regards
Axel
