title: Eclipse RCP, adding a new View to Editor
body: <p>How is it possible to put a View into an Editor. Something like: </p>
  
  <pre><code>public class Perspective implements IPerspectiveFactory {
  public static final String ID = "com.example.gui.perspective";
  public void createInitialLayout(IPageLayout layout) {
      layout.setEditorAreaVisible(true);
      String editorArea = layout.getEditorArea(); 
      layout.addView(View.ID, IPageLayout.TOP, 0.6f, IPageLayout.ID_EDITOR_AREA);    
  ... 
  }
  </code></pre>
  
  <p>But there are only IPageLayout.TOP, IPageLayout.BOTTOM, IPageLayout.LEFT and IPageLayout.RIGHT options. I want to put it inside. How is it possible?</p>
