Re: native JsType with constants

Awesome. Thank you. @JsOverlay did the trick.

From https://groups.google.com/d/msg/google-web-toolkit-contributors/q_GY4SxGQ7I/KrExmCQ9EgAJ I think you need to annotate those constant fields with @JsOverlay.

Or maybe you could declare them non-final and have them mapped to the native constants ($wnd.Node.ELEMENT_NODE, etc.)

Hi

How can I add constants to a native @JsType?

I was trying to add support for constants to my WebIDL to JsInterop generator but I have a problem with constants.

Here is a snippet of the definition of Node


[Exposed=Window]
interface Node : EventTarget {
  const unsigned short ELEMENT_NODE = 1;
  const unsigned short ATTRIBUTE_NODE = 2; // historical
  const unsigned short TEXT_NODE = 3;
  ...
  readonly attribute unsigned short nodeType;
  readonly attribute DOMString nodeName;


And here is the corresponding Java that I generate


@JsType(isNative = true, namespace = JsPackage.GLOBAL)
public interface Node extends EventTarget {
  public static final short ELEMENT_NODE = 1;
  public static final short ATTRIBUTE_NODE = 2;
  public static final short TEXT_NODE = 3;
  ...
  @JsProperty(name = "nodeType") short getNodeType();
  @JsProperty(name = "nodeName") String getNodeName();


But GWT complains about it

[ERROR] Line 10: Native JsType field 'short Node.ELEMENT_NODE' cannot have initializer.

I tried adding @JsIgnore to the fields but was also illegal

Best regards
