for listening on events on your widget you can define UiHandler or Attach /
Add handlers
for example, if you have a button defined in your UIBinder

now if you want to listen on click event of this button, you can do either
of these two operations
@UiHandler("button1")
public void OnButton

Nicolas,
The first this I can think of is in your module definition you have not
included the path
Your UserServiceImpl is defined in your server package but you don't have
that included in the module.
Try adding that.

did you look at EntityProxyChange.registerForProxyType ? You can use this
and register for any changes to your entities with the eventBus. The Handler
method is called on change of entities (especially version changes).

you should be able to dynamically populate a drop list using requestFactory.
Once you fetch the data from the server, you can update your list.
The only instance where you would have to build a custom widget is when you
want to dynamically populate a SelectionCell with your dynamic data. For
that
you have not specified the events you want your cell to consume. You will
have to add a constructor and specify the events you want to consume
AbstractButtonCell() {

Victor,
based on what I read, your flowpanel is part of a view which is mapped to a
presenter. You are dynamically adding buttons to the flowpanel. You can
setup click handlers for each of your buttons. if the button is present and
clicked, its handler would be invoked. Inside the handler call the

look at the source code, the initialize method shows how to add new tabs.
You can add a button in one of these tab panels and on click of it create
new tabs.

Mark,
I think you should be able to achieve it using places. Try to have an
additional property in your place, lets say location which would tell you
which tab the user clicked. Now pass this value to the activity/ Delegate
which drives your view. Based on the location render the contents.

Very good.
if you are doing more than one image then placing them relative to each
other would be difficult using a HTMLPanel and table combination. In those
instances you can use an absolute panel

you are having this problem because your page is not able to resize

the problem is not with your TabLayout panel. what you have there would work
fine. The issue is with the Grid.
Its best to use LayoutPanels inside other layoutpanels. In your case if all
that you are doing is rendering two TabLayoutPanels, you don't have to
necessarily use a grid.
i would instead

best would be to do a place change, call the same activity, but re-use the

easiest way to clear a canvas is to use the context clearRect function and
pass the canvas co-ordinate space width & height. This would clear the
entire canvas. And you can redraw the shapes you want to remain on screen.
You can also clear portion of a screen, using the above function by passing
