public class MainButton
extends VCanvas

The MainButton class displays a flat button that responds to mouse over and mouse pressed events by changing its 3D appearance.

Icons can be added from vipratech.awt.ButtonIcon that also respond to these events.

The button can be wired to vipratech.beans.LanguageChoice at design time to display a locale senstive label.

By setting the boolean clickable variable to true, the button becomes toggled so that it stays recessed when clicked once and then snaps back to its normal enabled appearance after a second mouse release.

On mouse release the button generates an action event object which is sent to any registered action listeners.
