If we allowed mouse events to be applied to both a photo and the underlying desktop, we d get two sets of actions at once. With some applications this might be desirable, but in our (0,0) (200,0) (0,0) case it is not; the event should go to either an individual photo or the desktop, but not both!

The OpenJFX project is an open source initiative, sponsored by Sun Microsystems, to create the JavaFX Script compiler. This is where JavaFX Script, as a technology, is being engineered and experimented on; future versions of the language will spring from this project. Presumably in the future the API will be covered by an open source project too. The project site contains the latest compiler releases and their source code, although not necessarily an accompanying API release. If you want to play an active role in shaping the future of JavaFX itself, this is a good place to start. However, if you prefer to leave the nuances of language design to more experienced compiler engineers, you can ignore this site.
