Page Service

The page service provides information about the page in which the application is running, and enables you to perform the following tasks:

• Getting a list of the atomic names of the visible iViews in the page.

  You may want to use this method to avoid updating the user interface of an iView when it is not visible.

  IPageService pageService = (IPageService)
      WDPortalUtils.getService(IPageService.KEY);
  
  // String array receives iView names
  String[] iViews = pageService.getVisibleIViews();
  
                 

• Hiding/showing iViews in the page

  IPageService pageService = (IPageService)
      WDPortalUtils.getService(IPageService.KEY);
  
  // display iView Search
  pageService.showIView("Search");
  
  // hide iView Details
  pageService.hideIView("Details");
  
                 

  Note

  Changes to the visibility of iViews are not saved. When a user refreshes the page, the original settings are restored.
