GWT + SmartGWT + Javascript：外部脚本集成

Question

I am building a web application using GWT and SMartGWT and I need to integrate an external script for a Photo Gallery: http://slideshow.triptracker.net/ . My current attempt is:

ScriptInjector.fromUrl("http://slideshow.triptracker.net/slide.js").setCallback(
              new Callback<Void, Exception>() {
                     public void onFailure(Exception reason) {
                       Window.alert("Script load failed.");
                     }
                    public void onSuccess(Void result) {
                      Window.alert("Script load success.");
                     }
                  }).inject();

Afterwards, I call this method:

Code:

native static void example(String p) /*-{

     $wnd.viewer = new $wnd.PhotoViewer();
             $wnd.viewer.add(p)
     $wnd.viewer.show(0);

}-*/;

This does not give any error, but the photogallery appears BEHIND my Entry Point Layout, so it's not possible to use it.

So, I am trying to find a workaround and I would like to refer to the main layout from Javasript, to run the script on that. Is this possible? I've tried with

 foo.getElement().getId();

but it returns me something like

 isc_VLayout_0_wrapper

However, Javascript doesn't like it.

Then I tried

  foo.getDOM.getId();

  isc_1

But the result doesn't change.

Can someone help me fix this issue? Thank You.

I think here are two things, that are possibly wrong:

1. You have an onSuccess() callback you can call the jsni call from within.

    //1 ScriptInjector.fromUrl("http://slideshow.triptracker.net/slide.js").setCallback( new Callback<Void, Exception>() { public void onFailure(Exception reason) { //3a } public void onSuccess(Void result) { example("works"); //3b } }).inject(); //2 example("not loaded"); 

2. You may also try to call .setWindow(ScriptInjector.TOP_WINDOW) before calling .inject()
