The document provides an overview of the Griffon framework, which is a desktop application framework for building Swing-based applications in Groovy using the MVC pattern. It discusses why Griffon was created due to limitations in Swing, and covers topics like installation, project structure, configuration, application lifecycle, MVC implementation, testing, threading and plugins.

- 1. The Griffon Framework An Investigation by Jim Kirkbride
- 2. What is this Griffon thing anyway?
- 3. What Is Griffon? ● Desktop Application Framework ● Takes after Grails ● MVC-based ● Groovy-based ● Vastly simplifies writing Swing-based applications
- 4. Why Not Just Use Swing? ● Complex widget hierarchy ● Difficult to separate out business logic from view logic ● Difficult to properly manage threading ● Difficult to test ● Wouldn’t you rather write Groovy?
- 5. Getting Started ● gvm install griffon <version> ● set GRIFFON_HOME ● add GRIFFON_HOME/bin to path ● griffon create-app <app name> ● You’re in business!
- 7. ● Application.groovy ○ App title ○ Start-up Groups ○ MVC Groups ● BuildConfig.groovy ○ Environment settings ○ Jar Signing ○ Dependency resolution Configuration
- 8. Configuration Cont. ● Builder.groovy ○ SwingBuilder configuration ● Config.groovy ○ Log4j configuration ○ Global configuration
- 9. Application LifeCycle ● Initialize ● Startup ● Ready ● Shutdown ● Stop
- 10. About MVC...
- 11. MVC
- 12. Griffon MVC
- 13. ● Nothing more than beans with “bindable” properties ● Uses the @Bindable AST transformation ● Model != “Domain”! ● PropertyChange listeners Model
- 14. View ● Uses the SwingBuilder library to create layouts ● Uses model properties for two-way binding ● Converters ● Validators
- 15. Controller ● Actions defined as closures ● Manipulates model values ● Used to define threading
- 16. Services ● Just like Grails services ● Injectable ● No transactional capabilities
- 17. Application Events ● Built-in events ● Custom Events
- 18. What About Testing? ● GriffonUnitTestCase ● Access to Mock objects ● Integration and Unit testing ● Decidedly lacking in Acceptance Testing ○ FEST Plugin
- 19. Lets talk about everyone’s favorite topic…
- 20. Threading!
- 21. Threading ● Swing uses the “Event Dispatch Thread” ● Makes you write ugly code using SwingWorker ● Is completely simplified in Griffon!
- 22. Threading Cont. ● On the EDT: ○ execInsideUISync ○ execInsideUIAsync ● Outside the EDT: ○ execOutsideUI ● isUIThread ● execFuture
- 23. Eco System ● Griffon still in development ● Documentation is spotty at best, downright wrong at worst ● Andres is very active ● Griffon team is really responsive ● Tons of plugins (very hit or miss)
- 24. Thanks!
