在 WPF 中，如何使按钮处于按下状态而不是处于上方状态？

Question

我刚刚在 WPF window 中放置了一个完全正常的默认按钮，希望它有一些正常的按钮状态。但它只对鼠标悬停做出反应，而不是对鼠标按下做出反应。我只需要它有两种状态，这样我就可以不用 over 状态。我如何让它对按下的鼠标按钮做出反应？

这是我的按钮：

<Button Width="380"
        Height="80"
        FontSize="30"
        FontFamily="VAG Rounded"
        Background="#337A05"
        Foreground="White"
        Margin="0,15"
        Content="BACK TO GAMES" />

Answer 1

您必须更改它 style / template. You'll need to get acquainted with ControlTemplates and VisualStates. Here's a tutorial。

Answer 2

您可以在 Visual Studio 的设计模式下右键单击 Button 并选择编辑模板->编辑副本，然后根据您的要求修改默认控件模板，例如删除IsMouseOver 触发器并更改 IsPressed 触发器中 Background 属性 setter 的值：

<Window...>
<Window.Resources>
<Style x:Key="FocusVisual">
    <Setter Property="Control.Template">
        <Setter.Value>
            <ControlTemplate>
                <Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
<SolidColorBrush x:Key="Button.Static.Background" Color="#FFDDDDDD"/>
<SolidColorBrush x:Key="Button.Static.Border" Color="#FF707070"/>
<SolidColorBrush x:Key="Button.MouseOver.Background" Color="#FFBEE6FD"/>
<SolidColorBrush x:Key="Button.MouseOver.Border" Color="#FF3C7FB1"/>
<SolidColorBrush x:Key="Button.Pressed.Background" Color="Red"/>
<SolidColorBrush x:Key="Button.Pressed.Border" Color="#FF2C628B"/>
<SolidColorBrush x:Key="Button.Disabled.Background" Color="#FFF4F4F4"/>
<SolidColorBrush x:Key="Button.Disabled.Border" Color="#FFADB2B5"/>
<SolidColorBrush x:Key="Button.Disabled.Foreground" Color="#FF838383"/>
<Style x:Key="ButtonStyle1" TargetType="{x:Type Button}">
    <Setter Property="FocusVisualStyle" Value="{StaticResource FocusVisual}"/>
    <Setter Property="Background" Value="{StaticResource Button.Static.Background}"/>
    <Setter Property="BorderBrush" Value="{StaticResource Button.Static.Border}"/>
    <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
    <Setter Property="BorderThickness" Value="1"/>
    <Setter Property="HorizontalContentAlignment" Value="Center"/>
    <Setter Property="VerticalContentAlignment" Value="Center"/>
    <Setter Property="Padding" Value="1"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="true">
                    <ContentPresenter x:Name="contentPresenter" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                </Border>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsDefaulted" Value="true">
                        <Setter Property="BorderBrush" TargetName="border" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
                    </Trigger>
                    <!--<Trigger Property="IsMouseOver" Value="true">
                                <Setter Property="Background" TargetName="border" Value="{StaticResource Button.MouseOver.Background}"/>
                                <Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.MouseOver.Border}"/>
                            </Trigger>-->
                    <Trigger Property="IsPressed" Value="true">
                        <Setter Property="Background" TargetName="border" Value="{StaticResource Button.Pressed.Background}"/>
                        <Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Pressed.Border}"/>
                    </Trigger>
                    <Trigger Property="IsEnabled" Value="false">
                        <Setter Property="Background" TargetName="border" Value="{StaticResource Button.Disabled.Background}"/>
                        <Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Disabled.Border}"/>
                        <Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="{StaticResource Button.Disabled.Foreground}"/>
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
</Window.Resources>
<Grid>
    <Button Width="380"
    Height="80"
    FontSize="30"
    FontFamily="VAG Rounded"
    Background="#337A05"
    Foreground="White"
    Margin="0,15"
    Content="BACK TO GAMES"
    Style="{StaticResource ButtonStyle1}"/>
</Grid>
</Window>

不，没有属性您可以简单地设置来执行此操作 :) 您必须覆盖模板。
