When I wrote Groodle #3 I mentioned that JavaFX had a better syntax to enable and handle dragging of a shape, GraphicsBuilder's version is definitely more verbose but allows you to drag shapes, images and groups. Well not anymore, now all displayable nodes have a new property autoDrag, that when set to true will allow dragging of said displayable. The actual code is exactly the same but it allows you to set additional behavior and react to a displayable being dragged. Groodle #3 can be updated as follows
// goatee triangle( x: 60, y: 210, w: 40, angle: 180, f: 'brown', id: 'goatee', autoDrag: yes ){ filters { dropShadow( name: 'shadow', enabled: no ) } } ... def startDrag = { e -> def shape = e.target shape.borderWidth = 3 shape.borderColor = 'red' shape.filters['shadow'].enabled = true } def endDrag = { e -> def shape = e.target shape.borderWidth = 1 shape.borderColor = 'black' shape.filters['shadow'].enabled = false }
I also updated the code to follow Joshy's version, now that dropShadow and reflection (from Swingx) are also available as filters, I can finally render a shadow whenever a piece of clothing is dragged. Instead of creating a new filter each time (as in the jfx version) the shadow filter's enabled state changes according to the situation.

Screencasts of all Groodles are available too (thanks to vnc2swf, I love being back to Linux)

Keep on Groovying!
