public double ArrowTipToArrowTriangleBaseDistance { get { return (double)GetValue(ArrowTipToArrowTriangleBaseDistanceProperty); } set { SetValue(ArrowTipToArrowTriangleBaseDistanceProperty, value); } } </code></pre> 然后您需要重写 <pre><code>ArrangeOverride</code></pre>、<pre><code>MeasureOverride</code></pre> 和 <pre><code>OnRender</code></pre> 方法。前两个来自 Decorator 类，第三个来自 UIElement 类。 这里有一个很好的<a href="https://stackoverflow.com/questions/66818340/measureoverride-and-arrangeoverride-what-is-really-availablesize-desiredsize">链接</a>来理解前两个。在 <pre><code>OnRender</code></pre> 中，您有一个 DrawingContext，可以使用 DependenyProperties 绘制所需的形状。 在这些之后，您可以像这样在 xaml 中使用装饰器： <pre><code><localdecorators:ArrowBorderDecorator ArrowBaseHalfSegment="0" FillColor="{DynamicResource MahApps.Brushes.Accent3}" StrokeColor="{DynamicResource MahApps.Brushes.ThemeForeground}" ArrowBorderThickness="1" ArrowTipToArrowTriangleBaseDistance="10"> <TextBlock Text="{Binding Path=Title}" Foreground="{DynamicResource MahApps.Brushes.IdealForeground}" Padding="10 1 10 1" VerticalAlignment="Center" FontWeight="Bold"> </TextBlock></localdecorators:ArrowBorderDecorator> </code></pre> <a href="https://i.stack.imgur.com/bETwO.png" target="_blank"><img src="https://cdn.imgupio.com/i/AWkuc3RhY2suaW1ndXIuY29tL2JFVHdPLnBuZw==" alt=""/></a> <a href="https://i.stack.imgur.com/njfyp.png" target="_blank"><img src="https://cdn.imgupio.com/i/AWkuc3RhY2suaW1ndXIuY29tL25qZnlwLnBuZw==" alt=""/></a> </answer> </body></html>
