Well, if it works good for you...
But if you created a ScriptElement with the function test equal to i.e.
"function clickMe { window.alert("Click")}"
and then on the ButtonElement you set the value i.e.
setValue("clickMe()") it worked as well....
anyway
you're welcome!!!!

Just to let you know i tried something like that :
The wrap work perfectly with an element of the current dom but with an
element i get from the iframe it does not work
Code sample :
IFrameElement iframe = IFrameElement.as(this.getElement());
Document iframeDocument = iframe.getContentDocument();
Element el = (Element) iframeDocument.getElementById("myhrefElement");
Anchor testButton = Anchor.wrap(el);
testButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
Window.alert("CLIIIICKKK ");
}
});
By the way , thanks for your help

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
