使用Caliburn MVVM干净地分离UI [英] Clean separation of UI with Caliburn MVVM

问题描述

研究SL的各种MVVM框架。在Caliburn文档中，我在调用MessageBox的控制器中看到了一个代码。这是对的还是仅用于介绍？在Caliburn中是否有像Chinch MVVM中的MessageBox服务之类的东西？

Looking into various MVVM frameworks for SL. In the Caliburn documentation I saw a code in a controller that calls MessageBox. Is this right or is this just for intro? Is there something like MessageBox service in Caliburn like in Chinch MVVM?

推荐答案

这确实是介绍性代码，只是为了演示控制器方法实际执行。但是，我同意您所指出的问题：演示者中存在原始UI代码可能会导致不适当的混合视图关注。

It's indeed introductive code, just to demonstrate that the controller method is actually executed. Yet, I agree on the issue you pointed out: the presence of raw UI code in the presenter could lead to an inappropriate mix of view concerns.

关于MessageBox服务：在Caliburn v2（树干）ShellFramework模块中，有一个Question / Answer ViewModel，它抽象了MessageBox的功能，其优点是可以为对话框设计UI。
另外，滚动您自己的IMessageBox抽象并使用默认的WPF MessageBox提供基本的实现也非常简单。

About the MessageBox service: in Caliburn v2 (trunk), ShellFramework module, there is a Question/Answer ViewModel abstracting the functionality of a MessageBox, with the advantage of letting you to design the UI for the dialog. Also, it's very straightforward to roll your own IMessageBox abstraction and provide a basic implementation using the default WPF MessageBox.
