public class SwingReportView extends JPanel implements ReportView
The Swing implementation of ReportView, a container for a NavigationView, a ReportScrollView, and a StatusBar. By default, the SwingReportView consists of a SwingNavigationView containing a group tree, search view, etc., on the left, a SwingReportScrollView on the right, and a SwingStatusBar below both. It offers various methods of page navigation and settings
To obtain an instance of a SwingReportView, use the methods SwingReportViewer.addNewReportView(RenderData) and SwingReportViewer.createReportView(RenderData).
Also, similarly to SwingReportViewer, a SwingReportView object is highly customizable. It is possible to hide components or place your own components in place of the navigation view or status bar. Here are a couple of examples of what could be done with a SwingReportView:

Hide the navigation view

If your report view does not have a group tree, or does not need a navigation view, you might want to hide the navigation view. To do this, simply extract it with extractNavigationView(). This will cause the navigation view to be hidden. If you should later still want to get a reference to the navigation view object, this is possible using getNavigationView().

"Wrap" the status bar in an own component

Using the methods "extractStatusBar" and "insertAtStatusBarPosition" this is quite simple: 

StatusBar oldStatusBar = myView.extractStatusBar();

// We have now extracted the old status bar from the view - it should now no longer be
// visible in the report view. Now, we place this status bar into our own component.
// Let's say our own component has a green button called "TestGreen".

JPanel newStatusBar = new JPanel( new FlowLayout() );
JButton test = new JButton( "TestGreen" );
test.setBackground( Color.GREEN );
newStatusBar.add( woohoo );
newStatusBar.add( oldStatusBar );

// Now we take advantage of the "insertAtStatusBarPosition" method, which places the component
// we pass into the old status bar position.

myView.insertAtStatusBarPosition( newStatusBar );

Export the report to a file

Once again, this is quite simple using the given "export" method, combined with the various export constants from the interface ReportView: 

myView.export( ReportView.EXPORT_PDF, "C:/test.pdf" );

Cause the report to be re-rendered and refreshed 

myView.refresh();
