public class AniCheckbox

extends Component

implements Runnable

The AniCheckbox class has the same functionality as the java.awt.Checkbox class.

It creates a series of images from a "film strip" image, where the frames are laid out from left to right. The images are animated to reflect the "true" state and the first image is displayed, statically, to represent the "false" state.

It provides its own mouse listener to control the state change and can be used in a group configuration using the AniCheckboxGroup.
