* TextBoolean is the text implementation of the Boolean
* interactor. The boolean interactor like a checkbox, power button is

*
* All interactors extend the TextWidget class. *
*
* Created on:April 19, 2006
* Known bugs: None
* Thread safe: Yes
*
doChange() is the overridden method defined in the
* TextWidget to perform the necessary functions for an interactor.
