/**
The {@link org.havi.ui.HAnimation HAnimation} class is a user
interface component used to display animated graphical content (as
{@link org.havi.ui.HStaticAnimation HStaticAnimation}) which
additionally enables a user to navigate to it, i.e. it can have the
input focus. By default it uses the {@link org.havi.ui.HAnimateLook
HAnimateLook} to render itself.
The {@link org.havi.ui.HAnimation HAnimation} class supports
animating images in exactly the same way as the {@link
org.havi.ui.HStaticAnimation HStaticAnimation} class, with the
following exception:
- If the {@link org.havi.ui.HAnimation HAnimation} has different
content set for the supported states a change in
interaction state may cause an implementation-specific change to
the animation position to deal with animation content of different
length.
The parameters to the constructors are as follows, in cases where
parameters are not used, then the constructor should use the default
values.
