基于WPF实现3D导航栏控件_开发_开发者_运维开发者技术经验分享

wpF实现3D导航

框架支持.NET4 至 .NET8；

Visual Studio 2022;

AnimationNavigationBar3D 带有 3D 效果的导航栏控件的样式。包含多个 AnimationNavigationBar3DItem ，通过 UniformGrid 进行排列，超出显示区域的项可以滚动查看。

AnimationNavigationBar3DItem 继承 ListBboxItem 是&nbpythonsp;3D 导航栏中的每个项。使用 Viewport3D 来创建一个具有 3D 效果的容器，当鼠标移入或移出时，旋转动画来改变项的外观。它包含一个正面 Background 和一个背面 ContentBack ，可以显示不同的内容。使用可以根据需要自定义内容，如果在每个项中只设置了正面内容而没有设置背面内容，那么背面会自动克隆 GetXMLReader 并显示与正面相同的内容。

GetXmlReader 用于通过将 UIElement 对象转换为 XML 字符串，再将其转换回 UIElement 对象，实现对 UIElement 对象的克隆。

实现代码

1）新增 AnimationNavigationBar3D.cs 代码如下:

    public class AnimationNavigationBar3D : ListBox
    {
        static AnimationNavigationBar3D()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(AnimationNavigationBar3D),
                new FrameworkPropertyMetadata(typeof(AnimationNavigationBar3D)));
        }
        protected override bool IsItemItsOwnContainerOverride(object item)
        {
            return item is AnimationNavigationBar3DItem;
        }
        protected override DependencyObject GetContainerForItemOverride()
        {
            return new AnimationNavigationBar3DItem();
        }
    }

2）新增 AnimationNavigationBar3DItem.cs 代码如下:

    public class AnimationNavigationBar3DItem : ListBoxItem
    {
        public static readonly DependencyProperty FillProperty =
            DependencyProperty.Register("Fill", typeof(Brush), typeof(AnimationNavigationBar3DItem),
                new PropertyMetadata(null));

        public static readonly DependencyProperty ContentBackProperty =
            DependencyProperty.Register("ContentBack", typeof(object), typeof(AnimationNavigationBar3DItem),
                new PropertyMetadata(null));

        static AnimationNavigationBar3DItem()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(AnimationNavigationBar3DItem),
                new FrameworkPropertyMetadata(typeof(AnimationNavigationBar3DItem)));
        }

        public override void OnApplyTemplate()
        {
            base.OnApplyTemplate();
            if (ContentBack == null) 
                ContentBack = ControlsHelper.GetXmlReader(Content);
        }

        /// <summary>
        ///  Color fore
        /// </summary>
        public Brush Fill
        {
            get => (Brush)GetValue(FillProperty);
            set => SetValue(FillProperty, value);
        }

        /// <summary>
        ///  The content after the mouse is moved in
        /// </summary>
        public object ContentBack
        {
            get => (object)GetValue(ContentBackProperty);
            set => SetValue(ContentBackProperty, value);
        }
    }

3）新增 AnimationNavigationBar3D.xaml 代码如下:

4）新增 GetXmlReader.cs 代码如下:

 public static object GetXmlReader(object Content)
 {
     var originalContent = Content as UIElement;
     string contentXaml = XamlWriter.Save(originalContent);
     using (StringReader stringReader = new StringReader(contentXaml))

         using (XmlReader xmlReader = XmlReader.Create(stringReader))
         {
             object clonedContent = XamlReader.Load(xmlReader);

             if (clonedContent is UIElement clonedElement)
             {
                 return clonedElement;
             }
         }
     }
     return null;
