Hi Tom,

Not sure I follow... so, the following function is defined inside a
javascript file and not in a JRuby script.  I can=C2=B4t do this implicit
coercion.  I think I should load the ChangeListener interface and make it
available to javascript.  I=C2=B4m still learning all this, so I might just=
 be
confused.  If this is any help, I=C2=B4m just trying to follow the blog:
https://blogs.oracle.com/nashorn/entry/porting_from_the_browser_to, but
instead of using jjs, I=C2=B4m driving nashorn through JRuby.


function WebViewWrapper(onload) {
    var This =3D this;
    var WebView =3D Java.type("javafx.scene.web.WebView");
    var webview =3D new WebView();

    This.webview =3D webview;
    This.engine =3D webview.engine;
    This.window =3D undefined;
    This.document =3D undefined;

    // Make sure the JavaScript is enabled.
    This.engine.javaScriptEnabled =3D true;

    // Complete initialization when page is loaded.
    This.engine.loadWorker.stateProperty().addListener(new ChangeListener()
{
        changed: function(value, oldState, newState) {
            if (newState =3D=3D Worker.State.SUCCEEDED) {
                This.document =3D wrap(This.engine.executeScript("document"=
));
                This.window =3D wrap(This.engine.executeScript("window"));

                // Call users onload function.
                if (onload) {
                    onload(This);
                }
            }
        }
    });


Thanks....
