“IsMouseOver”wpf Mahapps时更改按钮颜色
当鼠标移到mahapp按钮上时,我试图改变它的背景色。问题是,如果我使用以下代码:“IsMouseOver”wpf Mahapps时更改按钮颜色,wpf,xaml,mahapps.metro,Wpf,Xaml,Mahapps.metro,当鼠标移到mahapp按钮上时,我试图改变它的背景色。问题是,如果我使用以下代码: <Button Content="Button" HorizontalAlignment="Left" VerticalAlignment="Bottom" Width="50" Height="50" HorizontalContentAlignment="Left" BorderBrush="{x:Null}" Foreground="{x:Null}" Margin="50,0,0,0">
<Button Content="Button" HorizontalAlignment="Left" VerticalAlignment="Bottom" Width="50" Height="50" HorizontalContentAlignment="Left" BorderBrush="{x:Null}" Foreground="{x:Null}" Margin="50,0,0,0">
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="Green"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="DarkGoldenrod"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
发现颜色确实改变,但我的按钮忘记是mahapp按钮,即它失去了样式。
如何在不丢失样式的情况下更改颜色?
谢谢请尝试以下操作:
<Button Content="Button" HorizontalAlignment="Left" VerticalAlignment="Bottom" Width="50" Height="50" HorizontalContentAlignment="Left" BorderBrush="{x:Null}" Foreground="{x:Null}" Margin="50,0,0,0">
<Button.Style>
<Style BasedOn="{StaticResource {x:Type Button}}" TargetType="Button">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Aqua"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
如何在不丢失样式的情况下更改颜色
您需要重新定义整个模板:
<Button Content="Button" HorizontalAlignment="Left" VerticalAlignment="Bottom" Width="50" Height="50"
HorizontalContentAlignment="Left" BorderBrush="{x:Null}" Margin="50,0,0,0">
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="{DynamicResource FlatButtonBackgroundBrush}" />
<Setter Property="BorderThickness" Value="0" />
<Setter Property="FontSize" Value="{DynamicResource FlatButtonFontSize}" />
<Setter Property="Foreground" Value="{DynamicResource FlatButtonForegroundBrush}" />
<Setter Property="Padding" Value="10 5 10 5" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}" xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro">
<Border x:Name="Border"
Margin="0"
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}">
<Controls:ContentControlEx x:Name="PART_ContentPresenter"
Padding="{TemplateBinding Padding}"
HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}"
VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"
Content="{TemplateBinding Content}"
ContentCharacterCasing="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=(Controls:ControlsHelper.ContentCharacterCasing)}"
ContentStringFormat="{TemplateBinding ContentStringFormat}"
ContentTemplate="{TemplateBinding ContentTemplate}"
ContentTemplateSelector="{TemplateBinding ContentTemplateSelector}"
RecognizesAccessKey="True"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="DarkGoldenrod" />
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Background" Value="{DynamicResource FlatButtonPressedBackgroundBrush}" />
<Setter Property="Foreground" Value="{DynamicResource FlatButtonPressedForegroundBrush}" />
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Foreground" Value="{DynamicResource GrayBrush2}" />
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
您不能仅覆盖ControlTemplate的一部分:
尝试提供基本样式:当我修改其他属性(如字体系列)时,防止了此类问题,时间不起作用。样式保持不变,但颜色不变,这是我使用模板的方式。这是问题的正确答案,比重新定义模板简单得多。我不知道为什么人们对我不感兴趣@但mm8的解决方案起了作用。
