5. Programming the User Interface

Designing the User Interface (UI) of your application has serious implications for your whole system. Applying a right design pattern such as Model-View-Presenter (MVP) makes for highly testable, well-layered implementations. The minimalistic view programming we apply is further reduced by using UiBinder (a GWT 2 novelty), which enables you to create the view layer by using XML, with practically no Java code at all. In this chapter we’ll work at developing the UI, applying all the mentioned tools and methods.^[1]
