Class HttpPane

java.lang.Object
  nextapp.echo.app.Component
      echopoint.internal.AbstractContainer
          echopoint.HttpPane

All Implemented Interfaces:

Serializable, RenderIdSupport

public class HttpPane
extends AbstractContainer

A component that uses a iframe to dislay the contents of a user specified URI. Note that unlike the EPNG HttpPaneEx component, this component is not a subclass of ContentPane and hence may be embedded anywhere within your application component hierarchy.

The following code sample shows usage of this component:

   import echopoint.HttpPane;
   import nextapp.echo.app.Column;

     ...
     final Column column = new Column();
     final String uri = "https://echopoint.dev.java.net/";
     final HttpPane pane = new HttpPane( uri );
     column.add( pane );
