  • You mean like the content of a panel showing in your browser and programmatically in you gwt application take a screenshot and send it to the server? – Hilbrand Bouwkamp Jul 31 '13 at 18:58
  • Ya, Either send it to the server or save it to the desktop of the clients computer – lufthansa747 Jul 31 '13 at 19:10
  • I don't think that it's possible, as it would be a major security leak, because it would allow to make a malicious injected program that would take a screenshot of some sensitive data on your web page. – Hilbrand Bouwkamp Jul 31 '13 at 19:15

Try using html2canvas. GWT Panel is just a html element with some javascript to handle the layout.

You can find html2canvas here: http://html2canvas.hertzen.com/
