That's right, GraphicsBuilder 0.4.1 is out. It is almost a complete rework from the previous version, the reason being that handling input events in the correct place required that the core assumptions be redesigned. Here is a list of what's new and what has been changed:

• Shapes have been separated in Shapes and Outlines, because outlines do not support filling (they are not closed shapes).
• path() is available in core, it is no longer provided by ext-jdk6.
• all shape operations support mouse events (though mouseEntered/mouseExited are temporally disabled).
• all Shape operations will honor the clip (following Chet's advice) with the exception of morph(), seems that Morph2D doesn't implement Shape.intersect() so I'll have to look for a workaround.
• Shapes and Outlines no longer support nesting of other Shapes and Outlines, use group() instead.
• color attribute changed to borderColor.
• strokeWidth attribute changed to borderWidth.
• group() will apply borderColor, borderWidth and fill into its children if defined at top level, any child may override those settings.
• Area operations now behave as expected if asShape is set to true.
• Area operations support a shape() placeholder than can reference a java.awt.Shape or a previous Shape operation.
• image() and paint operations are currently disabled (I'll update them as soon I finish chapter 5 of FRC).
• All operations support binding out of the box because their properties are bound (meaning that they will trigger a PropertyChangeEvent whenever their value changes).

There is still much work to be done, feedback is always appreciated.

Keep on Groovying!
