问题 I'm starting to develop a large GWT application, and after reading a lot of articles and blog posts, I'm trying to understand what is the difference between the 2.2 Model-View-Presenter and the 2.1 Activities-Places design patterns? Which pattern do you recommend and why? Should I use MVP simply because it is "newer"? On the other hand Places-Activities seems to be more "intuitive"... Or am i totally missing the point and MVP is just an improved version of Activities-Places? Thanks to all GWT

问题 I am and android developer and I have worked on all of these three architecture patterns in my applications. Also I have gone through several post's on stackoverflow about the difference of each. My understanding might not be 100% correct but this is what I know so far in brief. MVC - User input is received by controller. Controller updates the model then tells the view to update itself. MVP - View gets the user input and notify the Presenter. Presenter gets the data from Model and then sends

问题 I am currently trying to implement the MVP pattern on Android. However, I came to think about memory leaks (since the presenter holds a reference to the activity - the view). My question is, should I set the view of the presenter to null say onDestroy of the activity? This is my main activity: public class MainActivity extends AppCompatActivity implements MainView { private Button loadUser; private TextView mTextView; @Inject IMainPresenter mPresenter; @Override protected void onCreate(Bundle

问题 I'm not clear about this.... When having a gridview on the View, is the controller who has to set up the Data source, columns, etc? or I just have to expose the DataBinding stuff, fire it from the controller and let the html/codebehind on the view handle all the rendering and wiring up? To be more precise: on the view should I have private GridView _gv public _IList<Poco> Source { get {_gv.DataSource;} set {_gv.DataSource = value; _gv.DataBind();} } Or should it be (from MVP pattern - Passive

问题 I am a fan of Martin Fowler's (deprecated) model-view-presenter pattern. I am writing a Scala view class containing several button classes. I would like to include methods to set the action properties of the buttons, to be called by the presenter. A typical code fragment looks like this: private val aButton = new JButton def setAButtonAction(action: Action): Unit = { aButton.setAction(action) } This code is repeated for each button. If Java/Scala had the C preprocessor, I would create a macro

问题 I'm new to MVP . can I use tutorials created for asp.net MVC to learn MVP pattern foundations and basics? or differences are too much ? 回答1: The 2 patterns are pretty different. The MVP pattern could be used with classic WebForms whereas ASP.NET MVC already integrates lots of the MVC pattern's parts in the framework itself. The separation of concerns is already present. If you want to use MVP with classic WebForms you will have much more work because the pattern is non-existent in the

问题 I am using the Model-View-Presenter pattern in my project web and now I am with a doubt. How I do to treat session and cookie this scenario? How I do to write file using "Response.WriteFile" for example? 回答1: I think the most typical approach (and, in fact, the one used by ASP.Net MVC) is to wrap the HttpContext in an abstraction (like IContext or something) which exposes whatever subset of context functionality you need to get access to. If your using an IoC container, then you can pretty
