Class Description

Class ZoomingButton is a variant of the special button. Zooming buttons have targets. When a zooming button is touched, a box zooms from the button to its target.

Programming information

Subclass: often
Call its methods: rarely

You'll subclass class ZoomingButton when the basic special button behavior doesn't meet your needs, such as when you need the button's action to do more than just call a particular operation, or when your button must update itself. See the chapter on class SpecialButton for details.
