org.eclipse.ui.views.contentoutline
Class ContentOutlinePage


java.lang.Object
  extended by 

org.eclipse.ui.part.Page
      extended by 
org.eclipse.ui.views.contentoutline.ContentOutlinePage
All Implemented Interfaces:
ISelectionChangedListener, ISelectionProvider, IPage, IPageBookViewPage, IContentOutlinePage 
public abstract class ContentOutlinePage

extends 
Page

implements 
IContentOutlinePage, 
ISelectionChangedListener

An abstract base class for content outline pages.

Clients who are defining an editor may elect to provide a corresponding content outline page. This content outline page will be presented to the user via the standard Content Outline View (the user decides whether their workbench window contains this view) whenever that editor is active. This class should be subclassed.

Internally, each content outline page consists of a standard tree viewer; selections made in the tree viewer are reported as selection change events by the page (which is a selection provider). The tree viewer is not created until createPage is called; consequently, subclasses must extend createControl to configure the tree viewer with a proper content provider, label provider, and input element.

Note that those wanting to use a control other than internally created TreeViewer will need to implement IContentOutlinePage directly rather than subclassing this class.
