| /** |
| * Main class for the Property Sheet View. |
| * <p> |
| * This standard view has id <code>"org.eclipse.ui.views.PropertySheet"</code>. |
| * </p> |
| * <p> |
| * Note that property <it>sheets</it> and property sheet pages are not the |
| * same thing as property <it>dialogs</it> and their property pages (the property |
| * pages extension point is for contributing property pages to property dialogs). |
| * Within the property sheet view, all pages are <code>IPropertySheetPage</code>s. |
| * </p> |
| * <p> |
| * Property sheet pages are discovered by the property sheet view automatically |
| * when a part is first activated. The property sheet view asks the active part |
| * for its property sheet page; this is done by invoking |
| * <code>getAdapter(IPropertySheetPage.class)</code> on the part. If the part |
| * returns a page, the property sheet view then creates the controls for that |
| * property sheet page (using <code>createControl</code>), and adds the page to |
| * the property sheet view. Whenever this part becomes active, its corresponding |
| * property sheet page is shown in the property sheet view (which may or may not |
| * be visible at the time). A part's property sheet page is discarded when the |
| * part closes. The property sheet view has a default page (an instance of |
| * <code>PropertySheetPage</code>) which services all parts without a property |
| * sheet page of their own. |
| * </p> |
| * <p> |
| * The workbench will automatically instantiates this class when a Property |
| * Sheet view is needed for a workbench window. This class is not intended |
| * to be instantiated or subclassed by clients. |
| * </p> |
| * |
| * @see IPropertySheetPage |
