  Builder Basics Buildersare a form of a DSL Focused on Hierarchical Structures SwingBuilder is not the only Builder in G r oo v y XMLBuilder AntBuilder ObjectGraphBuilder Still Others… Swing applications follow a hierarchical model: Window Panel Button Builders are a perfect fit for making Swing UIs

  A Quick HelloWorldExample groovy.swing.SwingBuilder.build { frame( id: 'root', title:'Hello World', show:true, pack:true) { flowLayout()‏ label('Enter a message:')‏ textField(id:'name', columns:20)‏ button('Click', actionPerformed: { ActionEvent e -> if (name.text)‏ optionPane().showMessageDialog( root, name.text)‏ })‏ } }

  What's going on?Each node is syntactically a method call All of these method calls are dynamically dispatched Most don’t actually exist in bytecode Child closures create hierarchical relations Child widgets are added to parent containers SwingBuilder node names are derived from Swing classes Remove the leading ‘J’ from a Swing class when present SwingBuilder also supports some AWT classes like layouts

  GraphicsBuilder - BasicsGraphicsBuilder is to Java2D what SwingBuilder is to Swing It produces a hierarchy of GraphicsOperations (or nodes)‏ A specialized component is required to render graphicsOperations and handle input events: GraphicsPanel

  GraphicsBuilder - Featuresshapes - shape, outline, areas regular Java2D shapes from java.wt.geom additional shapes from jSilhouette paints - solid, gradients, composite strokes - from jhlabs filters - from swingx, jhlabs grouping, transfortmations , images svg - import/export via Batik swf - partial export (still experimental)‏

  Mixing Swing &Graphics Use SwingBuilder to build the UI Use GraphicsBuilder to draw anywhere you need in a GraphicsPanel in JLayeredPane in SwingX layered components in Jide’s overlay support
• 14.
  Tips & HintsUse SwingBuilder.build()‏ Use Expando for quick prototyping of beans Use ObservableMap for quick binding tests Reuse shapes as must as you can Group operations that may have the same settings applied (color, borderWidth, fill, transformations)‏
