EXPERIMENTAL coconut backend for awt/swing.

This backend allows using all subclasses of java.awt.Component. This includes swing (please do note that in Haxe the javax package is presented as java.javax at compile time).

Any pair of get${CamelCaseOp} / set${CamelCaseOp} and is${CamelCaseOp} / set${CamelCaseOp} with the right arities is considered an attribute. So this works:

<java.awt.Button label="You cannot click me!" enabled=${false} />

Anything that is a subclass of java.awt.Container is allowed to have children, which are added/removed via the corresponding API.

For any methods of the form add${EventType}Listener, coconut.awt will scan all the required methods for the listener and expose them as attributes, prefixed with on. A button with a click listener would look like so:

<java.awt.Button label="Click Me!" onMouseClicked=${Sys.println("yeah!")} />

If the handler you provide is not a function, it is implicitly wrapped in event -> $handlerBody. The event is the regular Java object, wrapped in a special abstract that forwards the full underlying API while adding a source property that is typed to the specific component type. E.g.:

<java.awt.TextInput onTextValueChanged=${Sys.println(event.source.getText())}/>
