title: How to double click the item to open the default editor with the content by using ResourceNavigator in RCP?
body: <p>This is my navigator view.</p>
  
  
  
  <pre class="lang-java prettyprint-override"><code>public class myNavigatorView extends ResourceNavigator {
  
  private NavigatorActionGroup navigatorActionGroup;
  private CollapseAllHandler collapseAllHandler;
  public myNavigatorView() {
      // TODO Auto-generated constructor stub
  }
  protected void makeActions() {
  
      navigatorActionGroup = new NavigatorActionGroup( this );
      setActionGroup(navigatorActionGroup);
  
      IHandlerService service = (IHandlerService) getSite().getService(IHandlerService.class);
      service.activateHandler(IWorkbenchCommandConstants.NAVIGATE_TOGGLE_LINK_WITH_EDITOR,
              new ActionHandler(navigatorActionGroup.toggleLinkingAction));
      collapseAllHandler = new CollapseAllHandler(this.getViewer());
      service.activateHandler(CollapseAllHandler.COMMAND_ID,
              collapseAllHandler);
  }
  }
  </code></pre>
  
  <p>And when I double clicked the item I selected,the content didn't show in the editor.</p>
  
  <pre class="lang-java prettyprint-override"><code>layout.setEditorAreaVisible(true);
  leftFolder.addView("BIT_DEC.myNavigator");
  </code></pre>
