Interface IWizardStep

All Superinterfaces:

IClusterable, Serializable

All Known Subinterfaces:

IDynamicWizardStep

All Known Implementing Classes:

DynamicWizardStep, StaticContentStep, WizardStep

public interface IWizardStep
extends IClusterable

Models one step in a wizard, and is the equivalent of one panel in a wizard from an end-user's perspective.

Typically, you would extend panel based wizard steps and provide a custom panel for the step instead of directly implementing this interface.

Swing Wizard Framework served as a valuable source of inspiration.
