這篇文章主要介紹了如何基于WPF實(shí)現(xiàn)簡(jiǎn)單的3D導(dǎo)航欄控件效果,文中的示例代碼講解詳細(xì),對(duì)我們的學(xué)習(xí)或工作有一定幫助,需要的小伙伴可以參考一下

WPF實(shí)現(xiàn)3D導(dǎo)航

框架支持.NET4 至 .NET8；

Visual Studio 2022;

AnimationNavigationBar3D 帶有 3D 效果的導(dǎo)航欄控件的樣式。包含多個(gè) AnimationNavigationBar3DItem ，通過(guò) UniformGrid 進(jìn)行排列，超出顯示區(qū)域的項(xiàng)可以滾動(dòng)查看。

AnimationNavigationBar3DItem 繼承 ListBboxItem 是 3D 導(dǎo)航欄中的每個(gè)項(xiàng)。使用 Viewport3D 來(lái)創(chuàng)建一個(gè)具有 3D 效果的容器，當(dāng)鼠標(biāo)移入或移出時(shí)，旋轉(zhuǎn)動(dòng)畫(huà)來(lái)改變項(xiàng)的外觀。它包含一個(gè)正面 Background 和一個(gè)背面 ContentBack ，可以顯示不同的內(nèi)容。使用可以根據(jù)需要自定義內(nèi)容，如果在每個(gè)項(xiàng)中只設(shè)置了正面內(nèi)容而沒(méi)有設(shè)置背面內(nèi)容，那么背面會(huì)自動(dòng)克隆 GetXmlReader 并顯示與正面相同的內(nèi)容。

GetXmlReader 用于通過(guò)將 UIElement 對(duì)象轉(zhuǎn)換為 XML 字符串，再將其轉(zhuǎn)換回 UIElement 對(duì)象，實(shí)現(xiàn)對(duì) UIElement 對(duì)象的克隆。

實(shí)現(xiàn)代碼

1）新增 AnimationNavigationBar3D.cs 代碼如下:

    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 代碼如下:

    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 代碼如下:

</ResourceDictionary>

4）新增 GetXmlReader.cs 代碼如下:

 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;

5）新增 AnimationNavigationBar3D.xaml 示例代碼如下:

    <wd:AnimationNavigationBar3DItem Background="#E21854" Fill="#FD3574">
        <StackPanel VerticalAlignment="Center">
            <Path

            <TextBlock HorizontalAlignment="Center" Text="Emoji" />
        </StackPanel>
    </wd:AnimationNavigationBar3DItem>
    <wd:AnimationNavigationBar3DItem Background="#41A545" Fill="#5EECA6">
        <StackPanel VerticalAlignment="Center">
            <Path
