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 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero"> <Style x:Key="ButtonFocusVisual"> <Setter Property="Control.Template"> <Setter.Value> <ControlTemplate> <Rectangle Margin="2" SnapsToDevicePixels="true" stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" strokeThickness="0" strokeDashArray="1 2"/> </ControlTemplate> </Setter.Value> </Setter> </Style> <!-- Resource dictionary entries should be defined here. --> <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}"> <Microsoft_Windows_Themes:ButtonChrome x:Name="Chrome" Background="{TemplateBinding Background}" RenderMouSEOver="False" Renderpressed="{TemplateBinding Ispressed}" RenderDefaulted="False" SnapsToDevicePixels="true" Style="{DynamicResource ButtonChromeStyle_noborder}"> <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/> </Microsoft_Windows_Themes:ButtonChrome> <ControlTemplate.Triggers> <Trigger Property="IsKeyboardFocused" Value="true"> <Setter Property="RenderDefaulted" TargetName="Chrome" Value="true"/> </Trigger> <Trigger Property="ToggleButton.IsChecked" Value="true"> <Setter Property="Renderpressed" TargetName="Chrome" Value="true"/> </Trigger> <Trigger Property="IsEnabled" Value="false"> <Setter Property="Foreground" Value="#ADADAD"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> <Style x:Key="RepeatButtonStyle_noflash" BasedOn="{StaticResource BaseButtonStyle}" targettype="{x:Type RepeatButton}"> <Setter Property="Stylus.IsPressAndHoldEnabled" Value="false"/> </Style> </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> </ControlTemplate> </Setter.Value> </Setter> </Style>
