Example 1 with ISourceViewerExtension3

use of org.eclipse.jface.text.source.ISourceViewerExtension3 in project eclipse.platform.text by eclipse.

the class AbstractTextEditor method createPartControl.

/**
 * The <code>AbstractTextEditor</code> implementation of this
 * <code>IWorkbenchPart</code> method creates the vertical ruler and
 * source viewer.
 * <p>
 * Subclasses may extend this method. Besides extending this method, the
 * behavior of <code>createPartControl</code> may be customized by
 * calling, extending or replacing the following methods: <br>
 * Subclasses may supply customized implementations for some members using
 * the following methods before <code>createPartControl</code> is invoked:
 * <ul>
 * <li>
 * {@linkplain #setSourceViewerConfiguration(SourceViewerConfiguration) setSourceViewerConfiguration}
 * to supply a custom source viewer configuration,</li>
 * <li>{@linkplain #setRangeIndicator(Annotation) setRangeIndicator} to
 * provide a range indicator,</li>
 * <li>{@linkplain #setHelpContextId(String) setHelpContextId} to provide a
 * help context id,</li>
 * <li>{@linkplain #setEditorContextMenuId(String) setEditorContextMenuId}
 * to set a custom context menu id,</li>
 * <li>{@linkplain #setRulerContextMenuId(String) setRulerContextMenuId} to
 * set a custom ruler context menu id.</li>
 * </ul>
 * <br>
 * Subclasses may replace the following methods called from within
 * <code>createPartControl</code>:
 * <ul>
 * <li>{@linkplain #createVerticalRuler() createVerticalRuler} to supply a
 * custom vertical ruler,</li>
 * <li>{@linkplain #createSourceViewer(Composite, IVerticalRuler, int) createSourceViewer}
 * to supply a custom source viewer,</li>
 * <li>{@linkplain #getSelectionProvider() getSelectionProvider} to supply
 * a custom selection provider.</li>
 * </ul>
 * <br>
 * Subclasses may extend the following methods called from within
 * <code>createPartControl</code>:
 * <ul>
 * <li>
 * {@linkplain #initializeViewerColors(ISourceViewer) initializeViewerColors}
 * to customize the viewer color scheme (may also be replaced),</li>
 * <li>
 * {@linkplain #initializeDragAndDrop(ISourceViewer) initializeDragAndDrop}
 * to customize drag and drop (may also be replaced),</li>
 * <li>{@linkplain #createNavigationActions() createNavigationActions} to
 * add navigation actions,</li>
