All Implemented Interfaces:

extends Object
implements ElementEnabler

A specialized implementation of the ElementEnabler interface that can change the enabled state of action groups.

An instance of this class is initialized with the name of the action group it should manipulate. The implementation of the setEnabledState() method obtains the current ActionStore object from the BeanContext managed by the passed in ComponentBuilderData object. This object is then used to change the enabled state of the action group in question accordingly.
