.net - 更改wpf中的按钮边框厚度？

Question

为什么Button的边框粗细没有改变？

如果我将边框厚度更改为 1 或 100，则没有关系。一样的。我想使用样式来更改它，而不是自定义模板。

 <Window x:Class="GUI.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    Title="MainWindow" Height="350" Width="525">
<Window.Resources>
    <Style x:Key="newYellowButton" TargetType="{x:Type Button}">
        <Setter Property="Width" Value="100"/>
        <Setter Property="Height" Value="100"/>
        <Setter Property="Background">
            <Setter.Value>
                <RadialGradientBrush Center="0.5,0.5" GradientOrigin="0.5,0.5" RadiusX="0.5" RadiusY="0.5" SpreadMethod="Pad" ColorInterpolationMode="SRgbLinearInterpolation">
                    <GradientStop Color="#FFEEEE3B" Offset="0.5" />
                    <GradientStop Color="#FFF0E49A" Offset="1" />
                </RadialGradientBrush>
            </Setter.Value>
        </Setter>
        <Setter Property="BorderThickness" Value="9"/>
        <Setter Property="BorderBrush" Value="Blue" />
        <Setter Property="Padding" Value="-4"/>
    </Style>
</Window.Resources>
<Grid>
    <Button Style="{StaticResource newYellowButton}" Content="Ok"/>
</Grid>

您可以通过更改Button's ControlTemplate来做到这一点。将这些样式、画笔等复制到您的资源字典中，然后更改您想要的值。

要更改边框粗细，请找到以下代码并进行所需的更改:

...
<Border 
      x:Name="Border"  
      CornerRadius="2" 
      BorderThickness="1"                             //CHANGE THIS VALUE
      Background="{StaticResource NormalBrush}"
      BorderBrush="{StaticResource NormalBorderBrush}">
      <ContentPresenter 
        Margin="2"
        HorizontalAlignment="Center"
        VerticalAlignment="Center"
        RecognizesAccessKey="True"/>
</Border>
...
