In fact it does not work :-/
I don't understand. In my debug i see the correct element but the wrap
fail. I suppose the wrap fail because the element is not attached to the
main DOM.
Is it possible in gwt to wrap an element from an iframe as widget attached
to the main module ?
Element currentElement = this.getElement();
IFrameElement iframe = IFrameElement.as(currentElement);
Document iframeDocument = iframe.getContentDocument();
Element el= (Element) iframeDocument.getElementById("testiframe");
final Anchor testButton = Anchor.wrap(el);
testButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
Window.alert("CLIIIICKKK ");
}
});
