MVP4g is an extended / enhanced version of MVP which removes the boilerplated code by using annotations to bind the Model-View-Presenter along with EventBus.

GWT is a very powerful framework that allows you to build efficient applications, especially if you follow the Best Practices described by Ray Ryan at Google IO 2009:

  • Event Bus
  • Dependency Injection
  • Model View Presenter
  • Place Service

See http://code.google.com/events/io/2009/sessions/GoogleWebToolkitBestPractices.html

Mvp4g provides the tools to efficiently without masses of boilerplate code, achieve these Best Practices.
