Re: send event (click) to an external html page

ARRRGGG !

Thank you all for your search and help.

I don't know how to workaround my problem.

So, I'll search (alone, again, ;-)
If I find anything, I'll tell you

Best,

Laurent

Thanks Thomas for clarification of messaging api. I believed that it is working only on same domain and that it is build just to standardize communication.

Best,

On the other hand, if you are loading iframe from the same domain, and have full control of iframe content you can use window.postMessage api for child - parent communication.

If it's from the same origin, you don't need postMessage. postMessage was specifically made for cross-origin communications.

See http://dev.w3.org/html5/postmsg/#web-messaging and http://www.whatwg.org/specs/web-apps/current-work/multipage/web-messaging.html#web-messaging for the spec, and http://html5demos.com/postmessage2 for a demo.

You will need to implement some JSNI methods in order to accomplish this in GWT.

or use Elemental.

I doubt it'll solve Laurent's use case though: he was talking about loading a third-party site, and never mentioned that site was "friendly" to the "calling GWT app" (he used Google as an example)
