hi
In JavaScript, in order to get the login status using the Facebook SDK, one
has to call the FB.getLoginStatus like so:
FB.getLoginStatus(function(response) {
if (response.status === 'connected') // DO SOMETHING
});
notice the *function(response) { ... } *that is passed as a parameter to
getLoginStatus.
I am able to map the FB object in GWT with the proper JSMethods like so:
@JsType(isNative = true)
public static interface FB {
void init(FBParamObj fbParamObj);
void getLoginStatus(CustomCallbackFunction callbackFunction);
}
However, I'm not sure how to define the *CustomCallbackFunction *
*callbackFunction* that I need to provide as a parameter to FB.getLoginStatus.
FB.getLoginStatus is provided by the Facebook SDK so I can not change it.
How do I create this JavaScript callback function in GWT so I can pass it
to the FB SDK as a parameter?
I'm sure I'm missing something very basic but I can't seem to find it in
the documentation.
Thank you for the help!
Tony
