Creating Observable from normal Java events

Question

What is the best way to create an Rx-Java Observable from the classical Java event pattern? That is, given

class FooEvent { ... }

interface Foo         


        

Answer 1

I don't think there's a way to create a generic observable for every possible event, but you can certainly use them wherever you need.

The RxJava source has some handy examples of how to create observables from mouse events, button events, etc. Take a look at this class, which creates them from KeyEvents: KeyEventSource.java.
