How do I add an IFrameElement inside a widget in GWT?

You can use the widget Frame

provided by GWT. GWT wraps IFrameElement

in a widget Frame

. You can use it like any other widget. Next, you can do all the manipulations for the IFrameElement

Frame widget. for example

FlowPanel fp = new FlowPanel();
Frame frame = new Frame("http://www.google.com/");
fp.add(frame);

      

        
        
        
      

    

You can read more about the frame wrapper here: http://www.gwtproject.org/javadoc/latest/com/google/gwt/user/client/ui/Frame.html
