c# – 当画笔用作背景时,如何从WPF重复按钮中删除边框和效果

我正在使用 WPF中的repeatbutton对象,该按钮需要基于图形(图像画笔背景,没有边框或其他多余的效果).

我遇到的问题是,无论我尝试什么,按钮周围仍然有一个白色矩形,而且,我不确定现在看了几个小时之后,我确信我理解为什么或如何删除它.

我在XAML中使用以下内容创建了按钮

<RepeatButton Content="" BorderThickness="0" HorizontalAlignment="Left" Margin="334,265,0" VerticalAlignment="Top" Width="149" Height="100" Background="{DynamicResource ImageBrush_Decrement}" Style="{DynamicResource RepeatButtonStyle_noflash}" d:LayoutOverrides="HorizontalAlignment"/>

你会注意到我引用了一个“RepeatButtonNoFlash”样式,我用它来删除defaultrender(因为它引起了闪烁效果,这种样式在共享字典中定义如下

<ResourceDictionary

解决方法

它来自Microsoft_Windows_Themes：ButtonChrome尝试用边框或其他东西替换它,应该摆脱它.

<Style x:Key="BaseButtonStyle" targettype="{x:Type ButtonBase}">
        <Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/>
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="BorderBrush" Value="Transparent"/>
        <Setter Property="BorderThickness" Value="0"/>
        <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
        <Setter Property="HorizontalContentAlignment" Value="Center"/>
        <Setter Property="VerticalContentAlignment" Value="Center"/>
        <Setter Property="Padding" Value="0"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate targettype="{x:Type ButtonBase}">
                    <Border Background="{TemplateBinding Background}">
                        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsEnabled" Value="false">
                            <Setter Property="Foreground" Value="#ADADAD"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
