GWT: add Widget to new Window browser

I have a GWT application with links to services by clicking on a link,a blank window is opened which I have to insert a progressBar (widget I created myself) until generation of service return url so I redirect the new window to that url. So my question how to inject a new widget into new window browser. Note: I used JSNI to open new window this way win =$wnd.open = $ (url, name, ""); and when servi开发者_Python百科ce is generated i use this:wnd.location = url;

Any help would be appreciated. Thanks in advance for your helps

In your case win is a handler to new window DOM's window property.

Try creating a new GWT module that contains only your progressbar and inject it in the new window via window.document:

win.document.write("<script type="text/javascript" language="javascript" 
    src="gwtmodule/gwtmodule.nocache.js"</script>");
