我有一个基本的 WPF 窗口,其标记如下:
<Window x:Class="Application.SomeWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="SomeWindow"
Topmost="True" WindowStyle="None" Height="39" Width="400"
ResizeMode="NoResize" ShowInTaskbar="False"
WindowStartupLocation="Manual" Background="Transparent"
Closing="Window_Closing" AllowsTransparency="True" Opacity="0">
<Border Background="CornflowerBlue" BorderBrush="Black" BorderThickness="0,0,0,0" CornerRadius="5,5,5,5" Opacity="0.75">
<Grid>
<!-- Display bar -->
<Image Grid.Row="1" Height="24" Margin="7,7,0,0" Name="img1" Stretch="Fill" VerticalAlignment="Top" Source="/Application;component/Images/dashboard/1.png" HorizontalAlignment="Left" Width="13" />
<Image Height="24" Margin="19,7,47,0" Name="image21" Source="/Application;component/Images/dashboard/2.png" Stretch="Fill" VerticalAlignment="Top" Grid.Row="1" Grid.ColumnSpan="2" />
<!-- Button 1 -->
<Button Style="{DynamicResource NoChromeButton}" Height="27" Margin="0,5,25,0" Name="btn1" Click="btn1_Click" VerticalAlignment="Top" Grid.Row="1" Grid.Column="1" HorizontalAlignment="Right" Width="23" ToolTip="1">
<Image Height="26" HorizontalAlignment="Right" Name="img1" Source="/Application;component/Images/dashboard/3.png" VerticalAlignment="Top" Width="22" Stretch="Fill" />
</Button>
<!-- Button 2 -->
<Button Style="{DynamicResource NoChromeButton}" Height="27" Margin="0,5,5,0" Name="btn2" Click="btn2_Click" VerticalAlignment="Top" Grid.Row="1" Grid.Column="1" HorizontalAlignment="Right" Width="23" ToolTip="2">
<Image Height="26" HorizontalAlignment="Right" Name="img2" Source="/Application;component/Images/dashboard/4.png" VerticalAlignment="Top" Width="22" Stretch="Fill" />
</Button>
</Grid>
</Border>
</Window>
这是它现在的样子:
我真正想做的是让它最初看起来像这样:
然后,一旦发生鼠标悬停,将背景不透明度从 0 淡入,使其看起来像第一张图像。问题是,如果我将Border
orGrid
Background
颜色设置Transparent
为目标是在鼠标悬停时淡入,那么 or 中的所有内容也会受到影响。Border
Grid
有没有办法分别管理窗口及其 UI 元素的不透明度?或者也许有一个完全不同的方法可以让这个背景在鼠标悬停时褪色?谢谢。
