WPF：创建动态进度指示器

发布于 2024-09-16 09:48:16 字数 847 浏览 8 评论 0原文

我目前正在尝试使用 WPF 在 C# 中编写带有进度指示器的应用程序：

<Path Canvas.Left="15" Canvas.Top="50" Stroke="Red" StrokeThickness="6" Data=" M 700,100 L 620,100 C 620,100 600,100 600,80 L 600,50 C 600,50 600,30 580,30 L 50,30 L 50,340 L 580,340 C 580,340 600,340 600,320 L 600,290 C 600,290 600,270 620,270 L 700,270" Name="Progress" StrokeDashCap="Flat" StrokeEndLineCap="Round" StrokeLineJoin="Round" StrokeStartLineCap="Round" StrokeMiterLimit="30">

至此指标就完成了。但是我还没有任何可能降低指示器的长度。我可以使用其他坐标重新绘制指示器，但这会有点复杂（考虑圆形部分）。另外，我无法用白色覆盖它，因为由于背景图像它必须是透明的。

有人知道如何实现我想要的吗？或者指出另一种可能的解决方案？

最好的问候，乔纳斯

I'm currently trying to write an application with a progress indicator in C# using WPF:

<Path Canvas.Left="15" Canvas.Top="50" Stroke="Red" StrokeThickness="6" Data=" M 700,100 L 620,100 C 620,100 600,100 600,80 L 600,50 C 600,50 600,30 580,30 L 50,30 L 50,340 L 580,340 C 580,340 600,340 600,320 L 600,290 C 600,290 600,270 620,270 L 700,270" Name="Progress" StrokeDashCap="Flat" StrokeEndLineCap="Round" StrokeLineJoin="Round" StrokeStartLineCap="Round" StrokeMiterLimit="30">

So far the indicator is finished. However I don't have any possibility to lower the length of the indicator yet. I could redraw the indicator using other coordinates but that would be kind of complicated (think about the rounded parts). Also I can't overlay it with white color as it must be transparent due to a background image.

Does anyone have an idea on how to achieve what I want? Or point me to another possible solution?

Best greetings,
