PropertySheet view a
* graph database access twist. It presents a property view based the active
* workbench part and the active part's current selection.
*
* * To get a property page for your own view or editor part you can do one of the * following: * *
* Object getAdapter(Class c) {
* if (c == IPropertyPage.class) {
* // Get the browse contexts to use from somewhere
* Set<String> browseContexts = Collections.singleton("...");
* return new StandardPropertyPage(getSite(), browseContexts);
* }
* return super.getAdapter(c);
* }
*
*
* This method also allows customization of the actual property page control
* that gets created. PropertyPage serves as a good starting point
* for your own version.IStandardPropertyPage which will make this view do the above
* automatically without implementing getAdapter.null if no editor contributed the current page
