注解

FrameworkElement 是 WPF 框架级别的元素类与 WPF core 级别的 UIElement 表示服务之间的连接点。FrameworkElement is the connecting point between WPF framework-level element classes and the WPF core-level set of UIElement presentation services. 有关这些概念的详细信息,请参阅WPF 体系结构For more information about these concepts, see WPF Architecture.

FrameworkElement 扩展 UIElement 并添加以下功能:FrameworkElement extends UIElement and adds the following capabilities:

  • 布局系统定义FrameworkElement 为在 UIElement中定义为虚拟成员的某些方法提供特定的 WPF 框架级实现。Layout system definition: FrameworkElement provides specific WPF framework-level implementations for certain methods that were defined as virtual members in UIElement. 最值得注意的是,FrameworkElement 密封了某些 WPF 核心级别的布局重写,而是提供了一个 WPF 框架级别等效项,派生类应改为重写。Most notably, FrameworkElement seals certain WPF core-level layout overrides, and instead provides a WPF framework-level equivalent that derived classes should override instead. 例如,FrameworkElement 密封 ArrangeCore 但提供 ArrangeOverrideFor example, FrameworkElement seals ArrangeCore but provides ArrangeOverride. 这些更改反映了这样一个事实:在 WPF 框架级别,有一个完全布局系统可呈现任何 FrameworkElement 派生类。These changes reflect the fact that at the WPF framework-level there is a full layout system in place that can render any FrameworkElement derived class. 在 WPF 核心级别,将构造基于常规 WPFWPF 的布局解决方案的某些成员是就地的,但布局系统的实际引擎并未定义。At the WPF core level, certain members that will structure a general WPFWPF based layout solution are in place, but the actual engine of the layout system is not defined. 请参阅布局以了解详细信息。For more information, see Layout.

  • 逻辑树: 一般的 WPFWPF 编程模型通常以元素树的形式表示。The logical tree: The general WPFWPF programming model is often expressed in terms of being a tree of elements. 支持将元素树表示为逻辑树,并支持在标记中定义该树在 FrameworkElement 级别实现。Support for expressing the tree of elements as a logical tree, and accompanying support for defining that tree in markup is implemented at the FrameworkElement level. 但请注意,FrameworkElement 特意不定义内容模型,而是将此责任留给派生类。Note however that FrameworkElement deliberately does not define a content model, and leaves that responsibility to derived classes. 有关详细信息,请参见 WPF 中的树For more information, see Trees in WPF.

  • 对象生存期事件: 通常,知道何时初始化元素(调用构造函数)或将元素首次加载到逻辑树中。Object lifetime events: It is often useful to know when an element is initialized (the constructor is called) or when the element is first loaded into a logical tree. FrameworkElement 定义了一些与对象生存期相关的事件,这些事件为涉及元素的代码隐藏操作提供有用的挂钩,如添加更多的子元素。FrameworkElement defines several events related to object lifetime that provide useful hooks for code-behind operations that involve elements, such as adding more child elements. 有关详细信息,请参阅对象生存期事件For more information, see Object Lifetime Events.

  • 数据绑定和动态资源引用支持: 数据绑定和资源的属性级别支持由 DependencyProperty 类实现并在属性系统中体现,但能够解析存储为 Expression 的成员值(这两种数据绑定的编程构造)和动态资源)是通过 FrameworkElement实现的。Support for data binding and dynamic resource references: The property-level support for data binding and resources is implemented by the DependencyProperty class and embodied in the property system, but the ability to resolve a member value that is stored as an Expression (the programming construct that underlies both data binding and dynamic resources) is implemented by FrameworkElement. 有关详细信息,请参阅数据绑定概述XAML 资源For more information, see Data Binding Overview and XAML Resources.

  • 样式: FrameworkElement 定义 Style 属性。Styles: FrameworkElement defines the Style property. 但是,FrameworkElement 尚未定义对模板的支持,或不支持修饰器。However, FrameworkElement does not yet define support for templates, or support decorators. 这些功能由控件类(如 ControlContentControl)引入。These features are introduced by control classes such as Control and ContentControl.

  • 更多动画支持: 某些动画支持已在 WPF 核心级别进行了定义,但 FrameworkElement 通过实现 BeginStoryboard 和相关成员对此进行了扩展。More animation support: Some animation support was already defined at the WPF core level, but FrameworkElement extends this by implementing BeginStoryboard and related members.

从类层次结构中可以看出,许多 WPFWPF 类直接或通过中间基类(如 PanelControl)派生自 FrameworkElementAs can be seen from the class hierarchy, many WPFWPF classes derive from FrameworkElement, either directly or through intermediate base classes such as Panel or Control.

如果要使用 FrameworkElement 作为基类,则可能需要首先检查现有的派生类。If you intend to use FrameworkElement as a base class, you might want to first examine the existing derived classes. FrameworkElement 提供了对许多基本方案的支持,但对于在 可扩展应用程序标记语言 (XAML)Extensible Application Markup Language (XAML)中创建 用户界面 (UI)user interface (UI) 的构建基块而言,还缺少一些需要用于 "元素" 的功能。FrameworkElement provides support for a number of basic scenarios, but also lacks a number of features that are desirable for an "element" in the sense of a building block that you use to create 用户界面 (UI)user interface (UI) in 可扩展应用程序标记语言 (XAML)Extensible Application Markup Language (XAML). 例如,FrameworkElement 不定义任何真正的内容模型;作为基类 FrameworkElement 不定义可创建 XAMLXAML 子元素的属性。For instance, a FrameworkElement does not define any true content model; FrameworkElement as a base class does not define a property that can create XAMLXAML child elements. 特别是,您可能需要查看 ControlContentControlIn particular, you might want to look at Control and ContentControl.
