基于WPF实现3D导航栏控件
作者：WPF开发者
这篇文章主要介绍了如何基于WPF实现简单的3D导航栏控件效果,文中的示例代码讲解详细,对我们的学习或工作有一定帮助,需要的小伙伴可以参考一下
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 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:
