Thanks again,
In below method - how to get "event " ? so as to use
event.clipboard.setData("text/plain", data), if I can get event handle then
I may achieve desired results.
public static native String setClipboardData(String data)/*-{
if($wnd.clipboardData && clipboardData.setData){
return $wnd.clipboardData.setData('Text',Data);
}
}
}-
