The doc.execCommand('copy'), while deprecated, still works. Eg:
@UiField TextBox myTextBox;
myTextBox.setFocus(true);
myTextBox.selectAll();
boolean success = copyToClipboard();
private static native boolean copyToClipboard() /*-{
return $doc.execCommand('copy');
}-*/;
If you run your site over HTTPS, the user grants permissions, and you jump
though lots of hoops, you can also use the $wnd.clipboardData.readText()
and $wnd.clipboardData.writeText(myText).
