更改窗口内容时的资源管理 [英] Resource management when changing window content

问题描述

首先，我对如何在一个窗口的多个页面"之间导航没有完全了解.

First of all, I do not feel completely educated on how to navigate between multiple "pages" of a window.

例如，我有一个名为 MainWindow 的窗口.在这里面，我有一个页眉和一个页脚.中间是一个包含内容的面板.该面板最初将包含内容 A.单击 A 中的某些内容后，我想从视图中删除 A 并显示一个包含内容 B 的新面板.但是，我希望 B 显示在同一窗口中(即，不隐藏窗口和打开一个新的).隐藏/显示这些面板是正确的方法吗?

For example, I have a Window called MainWindow. Inside of this, I have a header and a footer. In the middle is a panel which contains content. This panel will originally contain content A. Upon clicking something in A, I want to remove A from view and show a new panel with content B. However, I want B to be shown in the same window (i.e., not hide the window and open a new one). Is hiding/showing these panels the correct way to go about it?

如果使用面板切换机制是正确的方式，那么我担心资源管理.如果我将面板 A 设置为不可见，而将面板 B 设置为可见，我是否仍会加载来自两个面板的资源?如果我有大量面板要在它们之间切换，我不想为所有面板加载内容，而是要加载活动面板.我将如何确保正确处理这些不同视图之间的资源和内存?

If using the panel switching mechanism is the correct way, then I am worried about resource management. If I set panel A to not be visible, and panel B to be visible, will I still have resources from both panels loaded? If I have a large number of panels to switch between, I would not want to load content for all of them, but rather the active one. How would I go about making sure that I am correctly handling resources and memory between these different views?

如果我对如何在单个窗口内切换视图有完全错误的想法，请告诉我.谢谢.

If I have the completely wrong idea about how to switch views within a single window, please let me know. Thanks.

推荐答案

另一种选择是只使用一个 ContentPresenter，并将您的个人面板"放入其中，但一次只能放置一个.

One alternative is to just use a single ContentPresenter, and put your individual "panels" in there, but only one at a time.

您可以使用数据绑定来更改 ContentPresenter 中的绑定内容，而不是翻转可见性.这一次只会留下一个视图"，从而防止需要加载大量"面板.

Instead of flipping visibility, you could use Data Binding to change the bound content within the ContentPresenter. This would only leave a single "view" in place at a time, preventing the neeed for "a large number" of panels to be loaded.
