thanks for link to infoq article about dart - so... it seems my guess

If you want to pass objects between to separately compiled gwt modules
via javascript it can only be object that extend JavaScriptObject or
primitives.
but these can also be your custom overlay objects defined on both

chart.js script uses document.write() to write chart markup. in case
you put this dynamically in your HTML Widget's it would reload the
page (document.write behaviour).
the only possibility to create it on runtime in gwt is to put it into

hi,
look at this thread:

if you want to create custom widget that treats its node's content in
the way HTMLPanel does you probably need to write ElementParser.
in this case look at this post:
http://cafebab3.
hi,
as far as gwt 2.1. HTMLPanel was treated somohow special by uibinder.
(i'm not sure if it hasn't changed in newer versions)
normally a widget in ui binder could contain text or html when
implemented hasText and hasHTML interfaces. then the content of the
node in ui.xml was parsed as text or htm
If you work with spring you probably have a spring controller that
extends RemoteServiceServlet implementation. (look at this topic

you can stick interceptor on handleRequest method as normally in
Spring you would do :).
or if you need to get some piece of information from decoded payloa
and the example without a line of JSNI :)
but be aware of same-domain restriction when retrieving reference
iframe's content.
public class IframeStyleExample implements EntryPoint {
public static StyleElement addStyleSheet(FrameElement frameElement,
String cssText)
as to gwt-rpc simply make your RemoteServiceServlet implementation
also implement Spring's Controller interface. The rest goes
straightforward. Simply call doPost in your handleRequest
implementation and return null (no ModelAndView needed as doPost from
RemoteServiceServlet writes all needed direc
1. But Animation class in gwt seems to be quite handy. All you need is
bunch of custom interpolation functions. But these are easy to be
taken from MooTools (i did take se below :)) - (easing functions in
jquery behave slightly different so simple rewriting it in java drops
off).
2. Manuel - great
I used to implement every more complex widget as pair Presenter-View
(view as inner class).

use @UiTemplate annotation to point where the ui.xml file exists.
ui template can accept relative path or full package JNDI path
(however eclipse plugin sometimes behaves quirky with custom paths)

but to the original question ;)
you don,t need markup at all :).
ui:text element has been introduced because you could not use
{messages.messageKey} in plain text not as attribute. as title is an

Alex, But if your widgets are to be inserted at runtime what you
expect to define in uibinder template? a list or an array? it's not
the right place because these are visiual templates, and a visual
container for widgets is just a panel (or a div if u use htmlpanel as
root container),

still nobody mentioned gwt-query - which btw is truely a framework.
while i dont like it's jquery-like naming convention - i stay
impressed with the code itself, especially selector engine ;).
as to gxt and smart gwt - it was not sth i was looking for so i
abandoned using it.
gwt itself is a frame
Yes, you're right. It's a mistake. I copied your method signature and
forgot to remove void after adding FocusPanel as a return type.

so in java you have sth like that:

return slot;
}
in ui.xml:

Assuming you do not use FocusPanel in other cases in this Widget just
anototate addSlot with @UiFactory and return newly created slot from
it:
@UiFactory FocusPanel void addSlot() {
final FocusPanel fp = new FocusPanel();
vp.add(fp);
return fp;

@Alex,
When you extend Composite not Widget/UiObject, you "init it" with
initWidget() not setElement - you cannot provide UI implementations
that takes use of existing DOM Nodes in html page. without this
exception thera no other differences.
