Eclipse Platform
Release 3.5

org.eclipse.jface.wizard
Class Wizard

java.lang.Object
  extended by 
org.eclipse.jface.wizard.Wizard
All Implemented Interfaces:
IWizard
Direct Known Subclasses:
BasicNewResourceWizard, ExternalProjectImportWizard, FileSystemExportWizard, FileSystemImportWizard, ParticipantSynchronizeWizard, RefactoringHistoryWizard, RefactoringWizard, ZipFileExportWizard, ZipFileImportWizard

public abstract class Wizard
extends Object
implements IWizard

An abstract base implementation of a wizard. A typical client subclasses Wizard to implement a particular wizard.

Subclasses may call the following methods to configure the wizard:

  • addPage
  • setHelpAvailable
  • setDefaultPageImageDescriptor
  • setDialogSettings
  • setNeedsProgressMonitor
  • setTitleBarColor
  • setWindowTitle

Subclasses may override these methods if required:

  • reimplement createPageControls
  • reimplement performCancel
  • extend addPages
  • reimplement performFinish
  • extend dispose

Note that clients are free to implement IWizard from scratch instead of subclassing Wizard. Correct implementations of IWizard will work with any correct implementation of IWizardPage.
