EXACTLY
get the Document, creaate a ButtonElement from the Document.
But you must also create a ScriptElement and set the text of the
function and then call click from the ButtonElement

Hi Lara
you can not replace the element with your button becasue your
Button is a Widget
while the button that you want to put in there must be a ButtonElement
why ?
because the Widget are used by GWT to translate that code into
javascript.
Once translated in javascript work is done.
In your case you download a web page with the Frame, then google
ALSO provides mechanism to manipulate html page and Javascript
so your html page now must be handled by a reverse engineering and
threat that button as a ButtonElement
is that clear ?

To be honest i don't get it at all ...
An other idea was to get the Document of the Iframe. That i got
it , i even find the element i want by parsing the html.
But i dunno how replace this Element by a GWT button attached to
my main module ( I think it's necessary to show my popup ).
Thanks,

No you can't do that, but you have to take this other way:
extending our target, you want to add a Widget, because your
button is a Widget, into a Document as javascript language
provides.
Infact you get a Document made by Elements.
So I think you have to use the method appendChild where the
child is a ButtonElement
see
http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/index.html?com/google/gwt/dom/client/ButtonElement.html
<http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/index.html?com/google/gwt/dom/client/ButtonElement.html>
so you have to simulate javascript.
The Button you mean is a Widget and use to CREATE a
javascript, in that case everything has been already
translated into javascript
is that clear ?

Hi,
My goal is to set gwt button inside my iFrame. If I do a
RootPanel.get("my id").add(myButton) , it don't work because
the id is inside the iFrame.
I find out how get the Document of the iframe and get the
Div Element but i still don't know how set a button on this div.
Thanks,

Hi,
I am actually migrate a web application to GWT. In
order to reuse the existing page i put them in frame.
However i have to develop a new popup for one of them
and i would like to let this popup attached to the main
module.
Before i was parsing the html to get the element and
with RootPanel attach a button. I can't do that anymore
because it's in an Iframe.
So i try to fire an event on click inside the iFrame to
get the current element and if it's the right button
show the popup ...
The ONLOAD event work pretty well but the ONCLICK don't
work at all
my code sample :
package com.exp.client;
import com.google.gwt.user.client.DOM;
import com.google.gwt.user.client.Event;
import com.google.gwt.user.client.ui.Frame;
import com.google.gwt.user.client.Window;
public class CustomFrame extends Frame {
public CustomFrame(){
sinkEvents(Event.ONCLICK);
sinkEvents(Event.ONLOAD);
setUrl("http://www.google.com"; <http://www.google.com>);
setSize("900px","900px");
}
public void onBrowserEvent(Event event){
super.onBrowserEvent(event);
switch (DOM.eventGetType(event))
{
case Event.ONCLICK:
Window.alert("ONCLICK : "+
event.getEventTarget().toString() );
DOM.eventPreventDefault(event);
break;
case Event.ONLOAD:
Window.alert("ONLOAD");
DOM.eventPreventDefault(event);
break;
}
}
}
Thanks for your help
