Re: GWT history with push state

addEventListener indeed is an option (and I'd say possibly a better option), but AFAICT you could also have done:

DomGlobal.window.onpopstate = new OnpopstateFn() {

    @Override

    public onInvoke(Event event) {

        // do something

    }

});

I'm finally getting around to replacing these calls with Elemental2.

To replace the JSNI method:

public static native void initialise() /*-{

$wnd.onpopstate = $entry(function(e) {

@com.blah.YourClass::yourMethodThatListensForUrlChange()();

});

}-*/;

I would have thought it would be:

public static void initialise() {
DomGlobal.window.onpopstate.onInvoke(event -> {
// Do something
});
}

However, that doesn't compile, as onInvoke takes a @JsFunction, not a @FunctionalInterface.  So, I have to do something like this:

public static void initialise() {
DomGlobal.window.addEventListener("popstate", event -> {
// Do something
});
}

Is this correct?

As Tomas said, not directly with History.  It's simple JSNI though:

public static native void updateURL(String newUrl) /*-{

    $wnd.history.pushState(newUrl, "", newUrl);

}-*/;

public static native void initialise() /*-{

$wnd.onpopstate = $entry(function(e) {

@com.blah.YourClass::yourMethodThatListensForUrlChange()();

});

}-*/;
