io.guise.framework.component.layout.AbstractLayout.ConstraintsPropertyChangeListener

All Implemented Interfaces:

com.globalmentor.beans.GenericPropertyChangeListener<Object>, PropertyChangeListener, EventListener

Enclosing class:

AbstractLayout<T extends Constraints>

protected class AbstractLayout.ConstraintsPropertyChangeListener
extends com.globalmentor.beans.AbstractGenericPropertyChangeListener<Object>

A property change listener that listens for changes in a constraint object's properties and fires a layout constraints property change event in response. A LayoutConstraintsPropertyChangeEvent will be fired for each component associated with the constraints for which a property changed. Events are only fired for constraints of a type recognized by this layout.
