我正在尝试重新创建材料设计外观和感觉一个按钮。对于聚焦(悬停)状态,指南说要在按钮上产生12%#000000的阴影。我想知道如何在WPF中实现这一目标。
我一直在寻找一个好的选择,就是在按钮上添加一个不可打印的矩形,其不透明度为12%,颜色为#000000。我想把它作为一种风格实现,但我不知道该怎么做。
我的风格现在看起来像这样:
<Style x:Key="MaterialRaisedButton" TargetType="ToggleButton">
<Setter Property="Padding" Value="8 0"/>
<Setter Property="Margin" Value="8 6 8 6"/>
<Setter Property="Height" Value="36"/>
<Setter Property="MinWidth" Value="64"/>
<Setter Property="Foreground" Value="Black"/>
<Setter Property="Background" Value="{StaticResource MaterialSecondaryColorBrush}"/>
<Setter Property="Effect" Value="{StaticResource z-depth2}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ToggleButton">
<Grid>
<Rectangle RadiusX="4" RadiusY="4" Fill="#000000" Opacity="0.12"/>
<Border CornerRadius="4" Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="{StaticResource Material12Black}"/>
</Trigger>
</Style.Triggers>
</Style>
如果还有其他方法可以做到这一点,我也很满意:)

在矩形的填充中,您可以指定十六进制颜色的不透明度,如#00000000,前两个值是不透明度。所以12%将是#1e000000。当鼠标悬停在其他明智的不透明度为0时,以下将显示.5不透明度矩形。
<Rectangle.Style>
<Style TargetType="{x:Type Rectangle}">
<Setter Property="Opacity" Value="0"/>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Opacity" Value=".5"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="false">
<Setter Property="Opacity" Value="0"/>
</Trigger>
</Style.Triggers>
</Style>
</Rectangle.Style>
</Rectangle>

如果有人想要将代码重用于类似材料的按钮,则代码如下所示。我使用this stackoverflower的涟漪效果和this source的阴影。希望这可以帮助其他人在没有工具包的情况下重新创建材料设计:)
