在这张来 self 手机上 Spotify 应用程序的屏幕截图中,您可以看到他们在左下角和右下角做了一些看起来像部分边框的事情。我找不到任何特定的属性来模拟它,所以有人可以向我解释他们是如何做到的吗?

我试过使用边界半径,但除非我做错了什么,否则我认为这不是那么简单。他们只是在它下面有一个自定义形状吗?

最佳答案

更好的方法是重新设置 TextBox 的样式,使其在侧面有两个左右 Rectangle,在底部有一个以模仿半边框外观。

<Rectangle x:Name="BottomLine" Grid.ColumnSpan="2" Grid.Row="1" Grid.RowSpan="1" VerticalAlignment="Bottom" Height="2" Fill="{TemplateBinding BorderBrush}" />
<Rectangle x:Name="LeftVerticalLine" HorizontalAlignment="Left" Height="4" Margin="0,0,0,2" Grid.Row="1" Stretch="Fill" UseLayoutRounding="True" VerticalAlignment="Bottom" Width="2" RenderTransformOrigin="0.5,1" Fill="{TemplateBinding BorderBrush}">
<Rectangle.RenderTransform>
<CompositeTransform />
</Rectangle.RenderTransform>
</Rectangle>
<Rectangle x:Name="RightVerticalLine" HorizontalAlignment="Right" Height="4" Margin="0,0,0,2" Grid.Row="1" Stretch="Fill" UseLayoutRounding="True" VerticalAlignment="Bottom" Width="2" RenderTransformOrigin="0.5,1" Grid.ColumnSpan="2" Fill="{TemplateBinding BorderBrush}">
<Rectangle.RenderTransform>
<CompositeTransform />
</Rectangle.RenderTransform>
</Rectangle>

为什么更好?因为它们现在是 TextBox 模板的组件,所以您可以将动画应用于视觉状态以获得更好的用户体验。

例如,当TextBox处于Focused时,我想使用ScaleTransform放大左右Rectangle 模式告诉用户他们当前正在与此控件进行交互。

这是完整的样式。 :)
