It's been a while since my last post on GraphicsBuilder, but with the recent builder sightings and SwingBuilder news I knew I had to get back to work, fast. So the good news are that Swing components can now be embedded into a GraphicsPanel (or any Component that supports GraphicsOperations) through an special GraphicsBuilder node named 'swingView', here is a sample
rect( x: 10, y: 10, width: 290, height: 130, arcWidth: 20, arcHeight: 20, color: 'black', strokeWidth: 2 ) swingView { label( 'Groovy & Java2D', x: 20, y: 20 ) button( 'Click me', actionPerformed: { evt -> // do something cool with Groovy! }) }
The trick to arrange components is that GraphicsPanel has a null layout, so each component must define its bounds [x,y,width,height], both width and height will come from the components preferred size so only [x,y] should be specified, but if you recall the Swing/AWT API x and y are read-only properties, how can we solve this problem? thanks to Danno's efforts on SwingBuilder/FactoryBuilderSupport its now possible to register a closure (as many as you like as a matter of fact) to handle a node's attributes before the factories get first pick, the other piece of the puzzle is settings the bounds when the node has finished being built, and yes, it will also use a closure (as the attribute delegates) to handle postNodeCompletion (there are other improvements on FactoryBuilderSupport that warrant a post of their own).

But the goodies don't stop here, swingView will use a "standard" SwingBuilder by default, but you may pass a reference to any SwingBuilder subclass as well, for example SwingXBuilder or JideBuilder, enabling more nodes and more components with a single change as
rect( x: 10, y: 10, width: 290, height: 130, arcWidth: 20, arcHeight: 20, color: 'black', strokeWidth: 2 ) swingView( new JideBuilder() ){ label( 'Groovy & Java2D', x: 20, y: 20 ) jideButton( 'Click me', actionPerformed: { evt -> // do something cool with Groovy! }) }
The code should be up in a couple of days, once the demo app has been updated and retested.

Keep on Groovying!
