Finding out when a GWT module has loaded

Question

I am exporting a GWT method to native javascript in the following manner:

public class FaceBookGalleryEntryPoint implements EntryPoint {

    @Override
    p         


        

Answer 1

I would try to define a callback function in the hostpage and call it from GWT at the end of the onModuleLoad() method.

Hostpage function:

<script type="text/javascript">
  function onGwtReady() {
    loadGallery('blargh');              
  };
</script>

GWT:

public void onModuleLoad() {
  FacebookGallery facebookGallery = new FacebookGallery();
  RootPanel.get().add(facebookGallery);

  initLoadGallery(facebookGallery);

  // Using a deferred command ensures that notifyHostpage() is called after
  // GWT initialisation is finished.
  Scheduler.get().scheduleDeferred(new Command() {
    public void execute() {
      notifyHostpage();
    }
  }
}

private native void notifyHostpage() /*-{
  $wnd.onGwtReady();
}-*/;
