Reactive Dialogs and Alerts

[thomasnield]

I discovered a factory to implement reactive dialogs and alerts is quite simple.

Implementation

public static <T> Observable<T> fromDialogSource(final Dialog<T> dialog) {
    return Observable.fromCallable(dialog::showAndWait)
            .subscribeOn(JavaFxScheduler.getInstance())
            .filter(Optional::isPresent)
            .map(Optional::get);
}

Usage

JavaFxObservable.fromDialog(alert)
    .filter(response -> response.equals(ButtonType.OK))
    .subscribe(System.out::println,Throwable::printStackTrace);

I think I'm going to do a release with this and the fix for #36. Did I oversimplify this factory? Is there anything else that needs to be added?

Dang it, Travis build is failing due to its usage of Java version "1.8.0_31". Dialogs are only supported in 1.8.0_40 upwards. I can't find any current information beyond fall of 2015, but it seems Travis doesn't support beyond 1.8.0_31. I may have to turn off Travis unless anybody has ideas.

Never mind fixed it. This modification to YML did the trick.
