Class Scrollbar

    com.sas.visuals.Scrollbar

All Implemented Interfaces:
  CompositeInterface, ContainerInterface, com.sas.awt.print.PrintableInterface, VisualInterface, com.sas.beans.PropertyChangeSource, com.sas.beans.VetoableChangeSource, ComponentInterface, DesignTimeDropTargetInterface, LinkPropertiesInterface, ModelInterface, IncrementInterface, ValidatorInterface, ViewInterface, MultipleValueEventSourceInterface, java.awt.Adjustable, java.awt.event.ActionListener, java.awt.event.AdjustmentListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.beans.PropertyChangeListener, java.io.ObjectInputValidation, java.io.Serializable, java.util.EventListener

    public class Scrollbar

implements java.awt.event.ActionListener, java.awt.Adjustable, java.awt.event.AdjustmentListener, IncrementInterface

Scrollbar is a class that creates a lightweight scrollbar. This scrollbar has default behavior similar to the java.awt.Scrollbar. It supports a com.sas.models.BoundedNumberInterface model, and uses a com.sas.models.BoundedLong model by default.
Notes:

- Setting the maximumReachable property currently allows the thumb to be dragged until the value of the scrollbar is the maximum. The value may continue to change until it reaches the maximum even if the mouse is past the end of the scrollbar when this property is on.
