问题描述
快速WPF的问题 - 在Win 7（相信Vista的）WPF中，默认的进度条做一个可爱的小彤彤嗖-y动画
我展示了约48个东西在一个屏幕上的进步，它的一点点铺天盖地地拥有所有这些东西呼呼的你 - 你可以仅禁用这些动画没有在应用程序影响默认的动画其余
解决方案
我会同意与马修的评论，但无论如何，你的答案是应用自定义样式没有动画。这里的原始风貌（通过反射器），你可以删除/调整/什么：

Quick WPF question - on Win 7 (and I assume Vista) in WPF, the default progress bar does a nice little glowing "whoosh"-y animation.
I'm showing progress of about 48 things on one screen, and it's a tad overwhelming to have all of these things whooshing on you - can you disable just these animations without affecting the rest of the default animations in the application?
解决方案
I'd agree with Matthew's comment, but anyway, your answer is to apply a custom style without the animation. Here's the original style (via reflector), you can remove/tweak/whatever:
<Style x:Key="{x:Type ProgressBar}" TargetType="{x:Type ProgressBar}">
<Style.Triggers>
<Trigger Property="Orientation" Value="Vertical">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ProgressBar}">
<Border Background="{TemplateBinding Background}" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}" CornerRadius="3" SnapsToDevicePixels="true">
<Border BorderThickness="1,1,1,0" BorderBrush="#BEBEBE" CornerRadius="2">
<Border BorderThickness="1" BorderBrush="#EFEFEF" CornerRadius="1">
<DockPanel Name="PART_Track" Margin="0,0,0,1" LastChildFill="false">
<Decorator Name="PART_Indicator" Dock="Bottom">
<Rectangle LayoutTransform="{RotateTransform Angle=-90}">
<Rectangle.Fill>
<MultiBinding Converter="{theme:ProgressBarBrushConverter}">
<Binding Path="Foreground" RelativeSource="{RelativeSource TemplatedParent}" />
<Binding Path="IsIndeterminate" RelativeSource="{RelativeSource TemplatedParent}" />
<Binding Path="ActualHeight" ElementName="PART_Indicator" />
<Binding Path="ActualWidth" ElementName="PART_Indicator" />
<Binding Path="ActualHeight" ElementName="PART_Track" />
</MultiBinding>
</Rectangle.Fill>
</Rectangle>
</Decorator>
</DockPanel>
</Border>
</Border>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
<Setter Property="Foreground" Value="{StaticResource [0] Ñ}" />
<Setter Property="Background" Value="{DynamicResource {x:Static WindowBrush}}" />
<Setter Property="BorderBrush" Value="#686868" />
<Setter Property="BorderThickness" Value="1" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ProgressBar}">
<Border Background="{TemplateBinding Background}" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}" CornerRadius="3" SnapsToDevicePixels="true">
<Border BorderThickness="1,1,1,0" BorderBrush="#BEBEBE" CornerRadius="2">
<Border BorderThickness="1" BorderBrush="#EFEFEF" CornerRadius="1">
<DockPanel Name="PART_Track" Margin="1,0,0,1" LastChildFill="false">
<Rectangle Name="PART_Indicator">
<Rectangle.Fill>
<MultiBinding Converter="{theme:ProgressBarBrushConverter}">
<Binding Path="Foreground" RelativeSource="{RelativeSource TemplatedParent}" />
<Binding Path="IsIndeterminate" RelativeSource="{RelativeSource TemplatedParent}" />
<Binding Path="ActualWidth" ElementName="PART_Indicator" />
<Binding Path="ActualHeight" ElementName="PART_Indicator" />
<Binding Path="ActualWidth" ElementName="PART_Track" />
</MultiBinding>
</Rectangle.Fill>
</Rectangle>
</DockPanel>
</Border>
</Border>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
And the converter class:
public class ProgressBarBrushConverter : IMultiValueConverter
{
// Methods
public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
{
Type type = typeof(double);
if (((((values == null) || (values.Length != 5)) || ((values[0] == null) || (values[1] == null))) || (((values[2] == null) || (values[3] == null)) || ((values[4] == null) || !typeof(Brush).IsAssignableFrom(values[0].GetType())))) || ((!typeof(bool).IsAssignableFrom(values[1].GetType()) || !type.IsAssignableFrom(values[2].GetType())) || (!type.IsAssignableFrom(values[3].GetType()) || !type.IsAssignableFrom(values[4].GetType()))))
{
return null;
}
Brush brush = (Brush) values[0];
bool flag = (bool) values[1];
double d = (double) values[2];
double num2 = (double) values[3];
double num3 = (double) values[4];
if ((((d <= 0.0) || double.IsInfinity(d)) || (double.IsNaN(d) || (num2 <= 0.0))) || (double.IsInfinity(num2) || double.IsNaN(num2)))
{
return null;
}
DrawingBrush brush2 = new DrawingBrush();
brush2.Viewport = brush2.Viewbox = new Rect(0.0, 0.0, d, num2);
brush2.ViewportUnits = brush2.ViewboxUnits = BrushMappingMode.Absolute;
brush2.TileMode = TileMode.None;
brush2.Stretch = Stretch.None;
DrawingGroup group = new DrawingGroup();
DrawingContext context = group.Open();
double x = 0.0;
double width = 6.0;
double num6 = 2.0;
double num7 = width + num6;
if (flag)
{
int num8 = (int) Math.Ceiling((double) (d / num7));
double num9 = -num8 * num7;
double num10 = d * 0.3;
brush2.Viewport = brush2.Viewbox = new Rect(num9, 0.0, num10 - num9, num2);
TranslateTransform transform = new TranslateTransform();
double num11 = num8 * 100;
DoubleAnimationUsingKeyFrames animation = new DoubleAnimationUsingKeyFrames();
animation.Duration = new Duration(TimeSpan.FromMilliseconds(num11));
animation.RepeatBehavior = RepeatBehavior.Forever;
for (int i = 1; i <= num8; i++)
{
double num13 = i * num7;
animation.KeyFrames.Add(new DiscreteDoubleKeyFrame(num13, KeyTime.Uniform));
}
transform.BeginAnimation(TranslateTransform.XProperty, animation);
brush2.Transform = transform;
while ((x + width) < num10)
{
context.DrawRectangle(brush, null, new Rect(num9 + x, 0.0, width, num2));
x += num7;
}
d = num10;
x = 0.0;
}
while ((x + width) < d)
{
context.DrawRectangle(brush, null, new Rect(x, 0.0, width, num2));
x += num7;
}
double num14 = d - x;
if ((!flag && (num14 > 0.0)) && (Math.Abs((double) (d - num3)) < 1E-05))
{
context.DrawRectangle(brush, null, new Rect(x, 0.0, num14, num2));
}
context.Close();
brush2.Drawing = group;
return brush2;
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture)
{
return null;
}
}
