Can anyone help me to copy the text to clipboard in a simple way and which works on all browsers

[Dhinakar Reddy Pothireddi]

Can anyone help me to copy the text to clipboard in a simple way and which works on all browsers especially on Safari, Chrome and IE and with out the need of flash or any other apps. Thanks in advance

        public static native void copyFrom(com.google.gwt.user.client.Element element) /*-{

  $wnd.window.clipboardData.setData('text', element.innerText);

}-*/;

public static native void pasteTo(com.google.gwt.user.client.Element element) /*-{

  $wnd.window.clipboardData.getData(element);

}-*/;

This code only works on IE and returns an exception on Chrome.

I need to process this event on a button click.

Hi,

Try this:
                                 

                             final HTML CopyIcon = new HTML("Copy");
                                    CopyIcon.setStyleName("gwt-HTMLGreen");
                                    CopyIcon.setTitle("Drag and Drop");
                                    CopyIcon.getElement().setDraggable(Element.DRAGGABLE_TRUE);

                                    CopyIcon.addDomHandler(new DragStartHandler() {

                                        @Override
                                        public void onDragStart(DragStartEvent event) {

                                            event.setData("text/plain", YOURDATATOCOPY);

                                            event.getDataTransfer().setDragImage(CopyIcon.getElement(), 10, 10);

                                        }

                                    }, DragStartEvent.getType());

Hope this helps

Ed

Sorry Ed, I didn't work and even this is not what I need. I want to access the clipboard in the Chrome with some appropriate JSNI. The code I posted previously works for IE but fails on Chrome. Thanks.

I'm using an implementation based on http://zeroclipboard.org/ [1]. ZeroClipboard is used by GitHub and should work on all modern browsers. My implementation is built using JsInterop and provides a subset of ZeroClipboard's API. It should be pretty easy to add more methods if you need them. 

Here's a sample how to use it:

Element button = Browser.getDocument().createButtonElement();
Clipboard clipboard = new Clipboard(button);
clipboard.onCopy(event -> event.client.setText("This text gets copied to the clipboard"));
