Creating Google gadgets with GWT - tutorial part 2

You should read part one before you continue here.


First lesson learned: you cannot get the HOST name of you gadget

String hostHost = Location.getHost().toLowerCase();

String hostName = Location.getHostName();

So I will be using URL parameters to set up my widget:

String gadget = Location.getParameter("gadget"); 

facebook4GWT API:

Creating Facebook gadgets in Google OpenSocial container does not work too well since you register the page on which Facebook app lives and in our case it is a Google server (e.g. 1.blogger.gmodules.com)

Facebook.init("7e52b37f9cc369XYZ1232");

Facebook.addLoginHandler(new FacebookLoginHandler()

{

    public void loginStatusChanged(FacebookLoginEvent event)

    {

if (event.isLoggedIn())

{

    facebookStatus.setText("Logged in");

    Facebook.APIClient().users_getLoggedInUser(new AsyncCallback()

    {

public void onSuccess(FacebookUser result)

{

    userName.setText(result.getName());

    userImage.setUrl(result.getPic());

    facebookStatus.setText(result.getStatus());

Solution for all this problems?

Use iFrame, I will investigate the best solutions in part 3 soon.
