wpf - 带有对角线装饰器的 ProgressBar 主题

Question

我想像下图一样装饰 WPF ProgressBar:

当前 :



装修 :



此外，那些空白的对角线应该在选取框动画中从左到右移动。目前我有这个简单的当前外观样式:

<Style x:Key="{x:Type ProgressBar}" TargetType="{x:Type ProgressBar}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ProgressBar}">
                <Border x:Name="BorderBackground" CornerRadius="3" BorderThickness="1" BorderBrush="{StaticResource ProgressBarBorderBrush}" Background="{StaticResource ProgressBarBackgroundBrush}">
                    <Grid>
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="CommonStates">
                                <VisualState x:Name="Determinate" />
                                <VisualState x:Name="Indeterminate" />
                            </VisualStateGroup>
                        </VisualStateManager.VisualStateGroups>
                        <Border x:Name="PART_Track" Margin="2" BorderThickness="1" CornerRadius="2" />
                        <Border x:Name="PART_Indicator" Margin="2" BorderThickness="1" CornerRadius="2" HorizontalAlignment="Left" Background="{StaticResource ProgressBarTrackBackgroundBrush}"/>
                    </Grid>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

任何人都可以帮我得到它吗？我搜索了它，但也许我错过了正确的关键字来找到这样的东西，至少我通常看到(如在 OS X 进度条上)通常使用这种“装饰”。

提前致谢 ;)。

答案代码稍加修改的解决方案模板:

<Style x:Key="{x:Type ProgressBar}" TargetType="{x:Type ProgressBar}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ProgressBar}">
                <Border x:Name="BorderBackground" CornerRadius="3" BorderThickness="1" BorderBrush="{StaticResource ProgressBarBorderBrush}" Background="{StaticResource ProgressBarBackgroundBrush}" Effect="{StaticResource LightStrongDownLinearShadowEffect}">
                    <Grid>
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="CommonStates">
                                <VisualState x:Name="Determinate" />
                                <VisualState x:Name="Indeterminate" />
                            </VisualStateGroup>
                        </VisualStateManager.VisualStateGroups>

Answer 1

编辑:

This来自 codeproject.com 的文章有一个“理发杆”进度条的工作版本。在文章中搜索“CandyCaneProgressPainter”。

上一个答案:

This几乎完全符合您的要求。您所要做的就是将矩形的可见性限制为您想要的百分比并更改高度/宽度比。

您想要的关键字是“ Storyboard”、“动画”和“触发器”

这是链接中的 xaml 以及链接中关于使动画平滑的一些评论:

 <Rectangle x:Name="pole" Width="100" Height="20" Stroke="Black" StrokeThickness="1">
  <Rectangle.Fill>
   <DrawingBrush TileMode="Tile" Stretch="None" Viewbox="0,0,1,1" Viewport="0,0,25,25" ViewportUnits="Absolute">
    <DrawingBrush.RelativeTransform>
     <TranslateTransform X="0" Y="0" />
    </DrawingBrush.RelativeTransform>
    <DrawingBrush.Drawing>
     <GeometryDrawing Brush="Red" Geometry="M10,0 25,0 15,25 0,25 Z" />    </DrawingBrush.Drawing>
   </DrawingBrush>
  </Rectangle.Fill>
  <Rectangle.Triggers>
   <EventTrigger RoutedEvent="FrameworkElement.Loaded">
    <BeginStoryboard>
     <Storyboard>
      <DoubleAnimation Storyboard.TargetProperty="(Rectangle.Fill).(DrawingBrush.RelativeTransform).(TranslateTransform.X)" From="0" To=".25" RepeatBehavior="Forever" Duration="0:0:1" />
     </Storyboard>
    </BeginStoryboard>
   </EventTrigger>
  </Rectangle.Triggers>
 </Rectangle>

I guess the jerking happens if you remove the "width" value, but if the value is put back it runs smooth. Weird.

Yup, indeed it basically needed a few adjustments with the multiples of the number rules the width in this case the animation can be a .1 or a .05 if for instance you have a 5000 width.... now it work great!
