如何删除 WPF 按钮上的默认鼠标悬停效果?

发布于 2024-09-25 15:49:27 字数 102 浏览 7 评论 0原文

我的问题是,在 WPF 中,每当我尝试使用触发器或动画更改按钮背景的颜色时,默认的鼠标悬停效果(带有橙色光芒的灰色)似乎优先。

经过大量搜索后,我对如何消除这种影响一无所知。

My problem is that in WPF, whenever I try and change the colour of a button's background using triggers or animations, the default mouseover effect (of being grey with that orange glow) seems to take priority.

After extensive searches I'm clueless as to how to remove this effect.

这与 Mark Heath 提到的解决方案类似,但没有那么多代码来创建一个非常基本的按钮,没有内置的鼠标悬停动画效果。它保留了简单的鼠标悬停效果,以黑色显示按钮边框。

例如,可以将样式插入到 Window.Resources 或 UserControl.Resources 部分(如图所示)。

<UserControl.Resources>
    <!-- This style is used for buttons, to remove the WPF default 'animated' mouse over effect -->
    <Style x:Key="MyButtonStyle" TargetType="Button">
        <Setter Property="OverridesDefaultStyle" Value="True"/>
        <Setter Property="Margin" Value="5"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border Name="border" 
                        BorderThickness="1"
                        Padding="4,2" 
                        BorderBrush="DarkGray" 
                        CornerRadius="3" 
                        Background="{TemplateBinding Background}">
                        <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter TargetName="border" Property="BorderBrush" Value="Black" />
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</UserControl.Resources>

<!-- usage in xaml -->
<Button Style="{StaticResource MyButtonStyle}">Hello!</Button>

This is similar to the solution referred by Mark Heath but with not as much code to just create a very basic button, without the built-in mouse over animation effect. It preserves a simple mouse over effect of showing the button border in black.

The style can be inserted into the Window.Resources or UserControl.Resources section for example (as shown).

<UserControl.Resources>
    <!-- This style is used for buttons, to remove the WPF default 'animated' mouse over effect -->
    <Style x:Key="MyButtonStyle" TargetType="Button">
        <Setter Property="OverridesDefaultStyle" Value="True"/>
        <Setter Property="Margin" Value="5"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border Name="border" 
                        BorderThickness="1"
                        Padding="4,2" 
                        BorderBrush="DarkGray" 
                        CornerRadius="3" 
                        Background="{TemplateBinding Background}">
                        <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter TargetName="border" Property="BorderBrush" Value="Black" />
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</UserControl.Resources>

<!-- usage in xaml -->
<Button Style="{StaticResource MyButtonStyle}">Hello!</Button>

只需添加一个非常简单的解决方案,这对我来说就足够了,我认为解决了OP的问题。我在这个答案中使用了解决方案,除了使用常规的背景值而不是图像。

<Style x:Key="SomeButtonStyle" TargetType="Button">
    <Setter Property="Background" Value="Transparent" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Grid Background="{TemplateBinding Background}">
                    <ContentPresenter />
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

除了强制 Background 始终为模板化按钮的 Transparent 背景之外,无需重新模板 - 完成此操作后,鼠标悬停将不再影响背景。显然将 Transparent 替换为任何首选值。

Just to add a very simple solution, that was good enough for me, and I think addresses the OP's issue. I used the solution in this answer except with a regular Background value instead of an image.

<Style x:Key="SomeButtonStyle" TargetType="Button">
    <Setter Property="Background" Value="Transparent" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Grid Background="{TemplateBinding Background}">
                    <ContentPresenter />
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

No re-templating beyond forcing the Background to always be the Transparent background from the templated button - mouseover no longer affects the background once this is done. Obviously replace Transparent with any preferred value.

您需要创建自己的自定义按钮模板才能完全控制所有状态下的外观。这是教程

You need to create your own custom button template to have full control over the appearance in all states. Here's a tutorial.

松饼人有一个非常简单的答案,对我有用。

要添加更具体的方向,至少对于 VS 2013:

  • 右键单击控件
  • 选择编辑模板 =>编辑副本...
  • 我选择了“应用程序”作为保存样式的位置
    • 从这里您可以直接编辑 App.xaml 并查看直观命名的属性。出于我的目的,我只是设置 RenderMouseOver="False"
  • 然后,在 MainWindow.xaml 中或 GUI 所在的任何位置,您可以将新样式粘贴到 Button 标记的末尾,例如 ... Style="{ DynamicResource MouseOverNonDefault}"/>

The Muffin Man had a very simple answer which worked for me.

To add a little more specific direction, at least for VS 2013:

  • Right-click the control
  • Select Edit Template => Edit a copy...
  • I selected 'Application' for where to save the style
    • From here you can directly edit App.xaml and see the intuitively named properties. For my purposes, I just set RenderMouseOver="False"
  • Then, in the MainWindow.xaml or wherever your GUI is, you can paste the new style at the end of the Button tag, e.g. ... Style="{DynamicResource MouseOverNonDefault}"/>

这个链接对我帮助很大
http://www.codescratcher.com/ wpf/remove-default-mouse-over-effect-on-wpf-buttons/

UserControl.ResourcesWindow.Resources 中定义样式

 <Window.Resources>
        <Style x:Key="MyButton" TargetType="Button">
            <Setter Property="OverridesDefaultStyle" Value="True" />
            <Setter Property="Cursor" Value="Hand" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="Button">
                        <Border Name="border" BorderThickness="0" BorderBrush="Black" Background="{TemplateBinding Background}">
                            <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
                        </Border>
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsMouseOver" Value="True">
                                <Setter Property="Opacity" Value="0.8" />
                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Window.Resources>

,然后添加以这种方式为您的按钮设置样式 Style="{StaticResource MyButton}"

<Button Name="btnSecond" Width="350" Height="120" Margin="15" Style="{StaticResource MyButton}">
    <Button.Background>
        <ImageBrush ImageSource="/Remove_Default_Button_Effect;component/Images/WithStyle.jpg"></ImageBrush>
    </Button.Background>
</Button>

This Link helped me alot
http://www.codescratcher.com/wpf/remove-default-mouse-over-effect-on-wpf-buttons/

Define a style in UserControl.Resources or Window.Resources

 <Window.Resources>
        <Style x:Key="MyButton" TargetType="Button">
            <Setter Property="OverridesDefaultStyle" Value="True" />
            <Setter Property="Cursor" Value="Hand" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="Button">
                        <Border Name="border" BorderThickness="0" BorderBrush="Black" Background="{TemplateBinding Background}">
                            <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
                        </Border>
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsMouseOver" Value="True">
                                <Setter Property="Opacity" Value="0.8" />
                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Window.Resources>

Then add the style to your button this way Style="{StaticResource MyButton}"

<Button Name="btnSecond" Width="350" Height="120" Margin="15" Style="{StaticResource MyButton}">
    <Button.Background>
        <ImageBrush ImageSource="/Remove_Default_Button_Effect;component/Images/WithStyle.jpg"></ImageBrush>
    </Button.Background>
</Button>

如果有人不想覆盖默认的控制模板,那么这里是解决方案。

您可以为可以具有 TextBlock 的按钮创建 DataTemplate,然后您可以在 IsMouseOver 属性上编写属性触发器以禁用鼠标悬停效果。 TextBlock 和 Button 的高度应该相同。

<Button Background="Black" Margin="0" Padding="0" BorderThickness="0" Cursor="Hand" Height="20">
    <Button.ContentTemplate>
        <DataTemplate>
            <TextBlock Text="GO" Foreground="White" HorizontalAlignment="Center" VerticalAlignment="Center" TextDecorations="Underline" Margin="0" Padding="0" Height="20">
                <TextBlock.Style>
                    <Style TargetType="TextBlock">
                        <Style.Triggers>
                            <Trigger Property ="IsMouseOver" Value="True">
                                <Setter Property= "Background" Value="Black"/>
                            </Trigger>
                        </Style.Triggers>
                    </Style>
                </TextBlock.Style>
            </TextBlock>
        </DataTemplate>
    </Button.ContentTemplate>
</Button>

If someone doesn't want to override default Control Template then here is the solution.

You can create DataTemplate for button which can have TextBlock and then you can write Property trigger on IsMouseOver property to disable mouse over effect. Height of TextBlock and Button should be same.

<Button Background="Black" Margin="0" Padding="0" BorderThickness="0" Cursor="Hand" Height="20">
    <Button.ContentTemplate>
        <DataTemplate>
            <TextBlock Text="GO" Foreground="White" HorizontalAlignment="Center" VerticalAlignment="Center" TextDecorations="Underline" Margin="0" Padding="0" Height="20">
                <TextBlock.Style>
                    <Style TargetType="TextBlock">
                        <Style.Triggers>
                            <Trigger Property ="IsMouseOver" Value="True">
                                <Setter Property= "Background" Value="Black"/>
                            </Trigger>
                        </Style.Triggers>
                    </Style>
                </TextBlock.Style>
            </TextBlock>
        </DataTemplate>
    </Button.ContentTemplate>
</Button>

dodgy_coder 答案的扩展,添加了对..

  • 维护 WPF 按钮样式
  • 添加对 IsSelected 和悬停(即切换按钮)的支持

     
    

示例。

An extension on dodgy_coder's answer which adds support for..

  • Maintaining WPF button style
  • Adds support for IsSelected and hover, i.e. a toggled button

        <Style x:Key="Button.Hoverless" TargetType="{x:Type ButtonBase}">
            <Setter Property="Template">

使用模板触发器:

<Style x:Key="ButtonStyle" TargetType="{x:Type Button}">
    <Setter Property="Background" Value="White"></Setter>
    ...
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Border Background="{TemplateBinding Background}">
                    <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
                </Border>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsMouseOver" Value="True">
                        <Setter Property="Background" Value="White"/>
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Using a template trigger:

<Style x:Key="ButtonStyle" TargetType="{x:Type Button}">
    <Setter Property="Background" Value="White"></Setter>
    ...
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Border Background="{TemplateBinding Background}">
                    <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
                </Border>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsMouseOver" Value="True">
                        <Setter Property="Background" Value="White"/>
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
