| org.zkoss.zk.ui.ext.render.Cropper
Cropper | public interface Cropper (Code) | | Implemented by the object returned by
org.zkoss.zk.ui.sys.ComponentCtrl.getExtraCtrl if not all of the children of a component are available at the client.
In other word, the component support 'cropping'.
Example: only children of the active page of ZUL's grid are available
at the client, if it is in the paging mold.
ZK Update Engine detects this interface and then ignores any update to
components that don't have counterpart at the client.
