public class Bar

extends SApplet

implements edu.davidson.tools.SDataListener

Bar is part of the Davidson College Physlets project. It is a subclass of SApplet and implements inter-applet communication using the SDataListener interface.

The following embedding parameters are defined:

Parameter	Value	Description
Value	10	The initial height of the bar.
Min	0	The minimum value.
Max	100.0	The full scale value.
Vertical	true	Vertical or horizontal display.
ShowControls	true	Show a text field below the bar.
