public class ImageButton
extends Canvas
An Image painted in a Canvas, bordered by a ThreeDRectangle.

ImageButtons have two constructors, both of which take an Image. The Image passed to the constructor must not be null; this is enforced by an assertion.

Default border thickness is 2 pixels - thickness may be set at construction time only.

Event handling is delegated to an ImageButtonController. By default, all ImageButtons are fitted with an instance of SpringyImageButtonController, however, setController(ImageButtonController) may be used to fit an ImageButton with a different derivation of ImageButtonController after construction.

ImageButtons ensure that their Images are completely loaded before they are displayed.

Drawn either raised or inset, current state may be queried via the isRaised() method.

disable() disables response to input and repaints the image with a bleached version. enable() restores the original image and enables response to input. The intensity of the bleaching effect may be controlled (for all ImageButtons) via the static setBleachPercent(int) method.
