我想要将WPF ProgressBar装饰成下面这张图片的样子:
当前状态:
装饰后:
此外,那些空白对角线应该从左到右以跑马灯动画移动。目前我只有这个简单的样式来呈现当前的外观:
<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>
有人可以帮我获取它吗?我搜索了一下,但可能错过了正确的关键字以查找类似这样的内容,至少我通常会看到(例如在OS X进度条上)通常使用这种“装饰”。
提前感谢;).
具有答案代码的解决方案模板稍作修改:
<Style x:Key="{x:Type ProgressBar}" TargetType="{x:Type ProgressBar}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ProgressBar}">

<Border x:Name="PART_Track" Margin="2" BorderThickness="1" CornerRadius="2" />
