Thomas, Thanks. I think I might be missing something very obvious, because I'm looking at the APIs, and I have no idea how to do what you're suggesting. Code-wise, how do I get the document within the frame, so that I can add the new Elements to it? - Joe On Jun 5, 6:24 pm, Thomas Broyer t.bro...@gmail.com wrote: You're adding your elements as children of the frame, which is used as a fallback in case the browser does support frames.

Thanks, that helped a lot, works as expected now! - Joe On Jun 6, 12:46 pm, Thomas Broyer t.bro...@gmail.com wrote: On Wednesday, June 6, 2012 6:13:04 PM UTC+2, King_V wrote: Thomas, Thanks.

Using the Frame class, and adding Elements to it directly - doesn't display?
All,
I've got this very short program, and I don't understand why it's not
working. I am creating a Frame object, trying to append element
children to it, and while the Frame instance seems to be aware of its
children, they do not get displayed.
Here is what I have. What am I doing wrong? When I attach to the
RootPanel, I get a blank rectangular square with nothing in it.
Inspection with Firebug also shows that the head and body elements are
empty.
public class TestFrameAndElement implements EntryPoint {
public void onModuleLoad() {
Frame frame = new Frame();
Element html = DOM.createElement(html);
Element head = DOM.createElement(head);
Element body = DOM.createElement(body);
Element element = DOM.createElement(div);
element.setInnerHTML(spanhello/spanspan style=\color: blue;
\goodbye/span);
html.appendChild(head);
html.appendChild(body);
body.appendChild(element);
frame.getElement().appendChild(html);
RootPanel.get().add(frame);
System.out.println(Frame children: +
frame.getElement().getChildCount());
System.out.println(HTML children : +
frame.getElement().getChild(0).getChildCount());
System.out.println(HEAD children : +
frame.getElement().getChild(0).getChild(0).getChildCount());
System.out.println(BODY children : +
frame.getElement().getChild(0).getChild(1).getChildCount());
System.out.println(DIV children : +
frame.getElement().getChild(0).getChild(1).getChild(0).getChildCount());
}
}
I've also noticed that if I do NOT add any elements, there is still an
html/head/body in the Frame section when I inspect with Firebug, but
in the code, the first sysout returns 0 and of course I have to
comment out the rest of the sysout statements.
How do I correctly work with this?
Thanks.

You're adding your elements as children of the frame, which is used as a fallback in case the browser does support frames. You should add them to the document that's displayed within the frame. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
