Examples of org.eclipse.jface.viewers.StructuredViewer

org.eclipse.jface.viewers.StructuredViewer
Abstract base implementation for structure-oriented viewers (trees, lists, tables). Supports custom sorting, filtering, and rendering.
Any number of viewer filters can be added to this viewer (using addFilter). When the viewer receives an update, it asks each of its filters if it is out of date, and refilters elements as required.
