Nested Presenters Framework GWTP

August 8, 2010 at 9:40 pm Leave a comment

A complete model-view-presenter framework to simplify your next GWT project is GWTP.

As compared with with gwt-presenter , GWTP mainly is known for solving the nested presenters drawback where the child presenters get injected with the constructor:

Most web applications use a consistent layout across all their pages, sharing elements such as the header or a menu bar. In an MVP architecture this is achieved by nesting presenters into one another. In gwt-presenter, WidgetContainerPresenter is the base class for nested presenters. However, its implementation requires you to pass all the subpresenters within the constructor. This goes against the principle of weak coupling, and practically defeats the purpose of using an event bus. In contrast, GWTP is entirely built around the idea of nested presenters. Revealing a presenter triggers a precise string of events that ripples up to the parent presenters, lazily instantiating any presenter that is needed in the process. GWTP’s presenters also have a clearly defined lifecycle on which you can easily hook custom behaviors.

It uses a program that operates at the command line to easily download GWTP, and get the samples.

C:\> hg clone gwt-platform
