Well it's the event "copy" as in my example. You need an eventHandler and then the event is passed as argument to your handler.
Hope that helps.

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);}}}-On Thu, Oct 20, 2022 at 5:17 PM Vassilis Virvilis <vasvir2@gmail.com> wrote:I believe I didIt's this snippet for copyevent.clipboardData.setData("text/plain", data);On Thu, Oct 20, 2022 at 1:52 PM Pramod Patil <patil.pramod63@gmail.com> wrote:Thank you again, I understand security implications but objective is to make it work for Edge, I have control over native methods, getClipBoardata and setClipboardData(String data) which are native methods in java. The code which I have pasted above is working fine with IE browser, but not with modern browsers. So can you help me with the code/pointers which can replace above code and work for Edge,Chrome. Thanks.--On Thursday, 20 October 2022 at 14:52:22 UTC+5:30 vas...@gmail.com wrote:Well if I remember correctly it is not supposed to access the clipboard directly because that would be a huge security issue.Consider the following scenario. You copy / paste your password for your bank somewhere. Then you go to a random webpage. If the javascript of this webpage that runs on your computer/browser could access (getClipboardData()) your clipboard your bank password would be compromised.So you can only access the clipboard from inside an event handler that handles the "copy" event aka Ctrl+C.The necessary details to access the data differ from IE and so I have posted examples.I do not know why your code does not compile. I think native methods are not checked so they tend to give NULL errors during runtime. If that is your case then caniuse is your friend.VassilisOn Thu, Oct 20, 2022 at 11:12 AM Pramod Patil <patil.p...@gmail.com> wrote:Hi Thanks for your response,on both front at GWT and Javascript I am at beginners level, will it be possible to have modification in below function, which will support copyclipboard functionality with Microsoft Edge.

I know this is not GWT specific question, but I don't have much knowledge with Javascript, so anyone who knows Javascript, please help here.
