WPF MVVM取消窗口关闭 [英] WPF MVVM cancel window closing

问题描述

我是新来WPF和MVVM。我想最小化窗口关闭它代替。换句话说，我想取消关闭窗口事件，并尽量减少此窗口。

I am new to WPF and MVVM. I would like to minimize the window instead of closing it. In other words, I would like to cancel Closing event of window and minimize this window.

我应该怎么做的MVVM方式？

How should I do that MVVM way?

如果是相关的，最后我将设置 ShowInTaskbar 到假和使用的WinForms盘组件。

If it's relevant, at the end I will set ShowInTaskbar to false and use WinForms tray component.

推荐答案

常见的误解MVVM是，有可能永远，永远是code隐藏在视图中。这是不正确的。

The common misunderstanding with MVVM is that there can never, ever be code-behind in a view. That is simply not true.

MVVM的目标是减少的的code在code-落后，但事情直接与视图本身（如Windows事件）进行交互，<强>这是可以接受的把一些code-背后。在code-后面会处理取消，并可以做到最小化，或者叫在视图模型的命令，或其他类似的东西。

The goal of MVVM is to minimize the code in the code-behind, but for things that directly interact with the view itself (such as Windows events), it is acceptable to put in some code-behind. The code-behind would handle the Cancel, and may do the minimize, or call a command in the ViewModel, or some other such thing.

否则，你将不得不拿出处理事件的视图模型，它通过具有视图模型打破MVVM模式一个令人费解的系统有一个参考视图（而不是周围的其他方法）。

Otherwise, you are going to have to come up with a convoluted system of handling the event in the ViewModel, which breaks the MVVM pattern by having the ViewModel have a reference to the View (instead of the other way around).
