com.vaadin.ui.AbstractSelect.CaptionChangeListener API 7.7.46 | Vaadin

You're viewing an older version of Framework JavaDoc. Please see version 7.7.47 for the latest.

com.vaadin.ui.

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().
