Wizards are used to guide the user through a sequenced set of tasks. Your plug-in can contribute wizards at predefined extension points in the workbench. It can also create and launch its own wizards.
When you contribute to a workbench wizard extension point, the actions that launch the wizard are already set up by the workbench. You need only supply the wizard that will be used.
If you need to launch other wizards that are not already defined in workbench wizard extension points, you must launch them yourself. You can launch your own wizards by adding an action to a view, editor, popup, or an action set.

The wizard dialog performs the enabling and disabling of the Next, Back, and Finish buttons based on information it obtains from the wizard and the current wizard page.
The wizard (IWizard) controls the overall appearance and behavior of the wizard, such as title bar text, image, and the availability of a help button. Wizards often use a corresponding DialogSettings to obtain (and store) the default values for the settings of controls on the wizard pages.

Your wizard page typically extends the WizardPage class. The primary responsibilities of your wizard page will include:
