复选框路径别名

Question

我在WPF中创建了一个复选框，但它看起来非常难看，框中的刻度非常粗糙。我试图将RenderOptions.EdgeMode设置为别名，但是没有修复它，我错过了什么？

代码如下：

<Style x:Key="{x:Type CheckBox}" TargetType="CheckBox">
        <Setter Property="SnapsToDevicePixels" Value="true"/>
        <Setter Property="OverridesDefaultStyle" Value="true"/>
        <Setter Property="FocusVisualStyle" Value="{DynamicResource CheckBoxFocusVisual}" />        
        <Setter Property="Foreground" Value="{StaticResource FGBrush}"/>
        <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
        <Setter Property="VerticalContentAlignment" Value="Stretch"/>
        <Setter Property="RenderOptions.EdgeMode" Value="Aliased"/>        
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="CheckBox">
                    <BulletDecorator Background="Transparent">
                        <BulletDecorator.Bullet>
                            <Grid Width="12" Height="12" MinHeight="{DynamicResource ResourceKey=MinimumIteractSizeDips}"
                                        MinWidth="{DynamicResource ResourceKey=MinimumIteractSizeDips}" 
                                  SnapsToDevicePixels="True" RenderOptions.EdgeMode="Aliased">

                                <Border x:Name="Border" 
                                        BitmapEffect="{StaticResource DropShadow}"
                                        MinHeight="{DynamicResource ResourceKey=MinimumIteractSizeDips}"
                                        MinWidth="{DynamicResource ResourceKey=MinimumIteractSizeDips}"

                                        BorderBrush="{StaticResource NormalBorderBrush}" RenderOptions.EdgeMode="Aliased">

Answer 1

如果我不得不猜测我会说它与Path对象中的所有小数有关，或者可能是Stretch=Fill

这是默认的CheckBox Path

<Path Visibility="Collapsed"
      Width="7"
      Height="7"
      x:Name="CheckMark"
      SnapsToDevicePixels="False"
      StrokeThickness="2"
      Data="M 0 0 L 7 7 M 0 7 L 7 0">
      <Path.Stroke>
           <SolidColorBrush Color="{DynamicResource GlyphColor}" />
      </Path.Stroke>
 </Path>

这是你的Path

<Path Stretch="Fill"
      Margin="3"
      x:Name="CheckMark"
      SnapsToDevicePixels="False" 
      Stroke="{StaticResource GlyphBrush}"
      StrokeThickness="3"
      Fill="{DynamicResource GlyphBrush}"
      RenderOptions.EdgeMode="Aliased"
      Data="M103.78572,598.96112 L105.09846,597.5661 L107.00806,600.16229 C107.00806,600.16229 109.91004,592.74463 109.91004,592.74463 C109.91004,592.74463 111.74678,593.79761 111.74678,593.79761 C111.74678,593.79761 107.88566,602.75848 107.88566,602.75848 L106.60118,602.75848 z" />

我建议一次更改一个属性，将您的版本更改为MSDN版本，并查看哪个修复了该问题。我猜它是Path.Data，但也可能是其他属性之一。
