Charlie,
Both of these fail:
Composer.register(AffineTransform.class.java_class,
TransformComposer.class.java_class)
error:
C:/Users/paulAdmin/Documents/NetbeansProjects/scene_graph_work/lib/scene_graph.rb:79:
undefined method `java_class' for Class:Class (NoMethodError)
Composer.register(AffineTransform.java_class,
TransformComposer.java_class)
error runtime:
com/sun/scenario/animation/Composer.java:162:in `register':
java.lang.IllegalArgumentException: Problem constructing appropriate
Composer for type class java.awt.geom.AffineTransform: (NativeException)
What form should the call take?
Thanks
Paul Fraser
