All Implemented Interfaces:

com.sun.kjava.ScrollOwner

public class BasicScrollTextBox

extends com.sun.kjava.TextBox

implements com.sun.kjava.ScrollOwner

A scrolling TextBox object. This is basically the com.sun.kjava.ScrollTextBox object with the bugs ironed out. I was unable to subclass ScrollTextBox and still get access to the bugs, so this is my interim solution. You need to control this class from a registered Spotlet. In the Spotlet class, implement penDown(), penMove() and keyDown() to call the handlePenDown(), handlePenMove() and handleKeyDown() methods of this class.
