Class AbstractSelect.CaptionChangeListener

java.lang.Object

com.vaadin.ui.AbstractSelect.CaptionChangeListener

All Implemented Interfaces:

Item.PropertySetChangeListener, Property.ValueChangeListener, Serializable

Enclosing class:

AbstractSelect

protected class AbstractSelect.CaptionChangeListener
extends Object
implements Item.PropertySetChangeListener, Property.ValueChangeListener

This is a listener helper for Item and Property changes that should cause a repaint. It should be attached to all items that are displayed, and the default implementation does this in paintContent(). Especially "lazyloading" components should take care to add and remove listeners as appropriate. Call addNotifierForItem() for each painted item (and remember to clear). NOTE: singleton, use getCaptionChangeListener().
