Re: [Ikvm-developers] How to pass a Java callable to C#?

[Jeroen F. <je...@su...>]

Hi Doug,

I'm probably misunderstanding the question, but in Java you'd use interfaces for this. See http://docs.oracle.com/javase/7/docs/api/java/awt/Button.html#addActionListener(java.awt.event.ActionListener) for example.

Regards,
Jeroen
