© 2012 Renesas Electronics America Inc. All rights reserved.18 Lab 2 Questions: 1 - How are we changing the color of the slider button? Determines the visual behavior of an associated object The usage of the scheme is dependent on object: In case of button handler – [0]: behavior in inactive state – [1]: behavior in active state In case of slider handler – [0]: appearance of the slider bar – [1]: appearance of the slider button

Completely custom behavior can be defined in the callback. A combination of custom behavior and screen object is typical. Creation of your own “Screen Objects” is encouraged. In case of “Touched” callback, no screen object is used.
