Question

I working on a MVP designed application and have some design questions. When writing code in the presenter-layer how should the communication go between different presenters/views? Lets say I have a WindowPresenter with its WindowView and I want to set the window title on a window from another window. I have a title-setter on the window view that wraps the actual gui title. Should I call the title-setter directly on the view (windowPresenter.View.Title = "Title") or should I wrap the view title as a presenter title setter (windowPresenter.Title = "Title") ?

Answer 1

Ask yourself how would you test it? If you do windowPresenter.View.Title = "Title", how can you test that presenter is setting the title?

Answer 2

There is a nice article that focuses quite a lot on similar things in MSDN magazine this month:
