ScrollSlider (SAS AppDevStudio API Developer Documentation for Java)

ScrollSlider creates an object that functions as the track area on a Scrollbar. The ScrollSlider has three main areas: an increment portion, a decrement portion and a draggable thumb portion separating the other two portions. There are individual ButtonModelInterface objects used for each of the three areas. One single ButtonListenerInterface object listens for user events and modifies the ButtonModelInterface objects accordingly. The increment and decrement areas button models are AlarmButtonModel to implement power scrolling while the mouse button is held down. The thumb uses a DefaultButtonModel. The listener is a SliderListener.

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 ScrollSlider when this property is on.
The requiredInterface is the com.sas.models.BoundedNumberInterface.
The default model is the com.sas.models.BoundedLong.
