Question

我想用丙烯酸刷子绘制Stack Panel表面。

<StackPanel Background="{ThemeResource SystemControlAcrylicElementBrush}"></StackPanel>

它对我有用，但是当我想要改变色调和不透明度时会出现问题。有以下代码可以更改它：

<ResourceDictionary.ThemeDictionaries>
<ResourceDictionary x:Key="Default">
    <AcrylicBrush x:Key="MyAcrylicBrush"
        BackgroundSource="HostBackdrop"
        TintColor="#FFFF0000"
        TintOpacity="0.8"
        FallbackColor="#FF7F0000"/>
</ResourceDictionary>

我不知道我应该把它放在哪里并为此重命名画笔？

 <StackPanel Background="{ThemeResource **MyAcrylicBrush**}"></StackPanel>

感谢您的帮助。附：您需要Windows Insider SDK和系统构建16190或更高版本

Answer 1

您可以创建ResourceDictionary，例如名为“ThemeDictionary.xaml”，并将您AcrylicBrush的代码放在那里。

然后在您的App.xaml中，您可以像ResourceDictionary一样引用您的<Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="ThemesDictionary.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources>：

方法1：

在ResourceDictionary.ThemeDictionaries

中添加Application.Resources

在App.xaml

中

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.ThemeDictionaries>
            <ResourceDictionary x:Key="Default">
                <AcrylicBrush x:Key="MyAcrylicBrush" BackgroundSource="HostBackdrop" TintColor="#FFFF0000" TintOpacity="0.8" FallbackColor="#FF7F0000"/>
            </ResourceDictionary>

            <ResourceDictionary x:Key="HighContrast">
                <SolidColorBrush x:Key="MyAcrylicBrush" Color="{ThemeResource SystemColorWindowColor}"/>
            </ResourceDictionary>

            <ResourceDictionary x:Key="Light">
                <AcrylicBrush x:Key="MyAcrylicBrush" BackgroundSource="HostBackdrop" TintColor="#FFFF0000" TintOpacity="0.8" FallbackColor="#FFFF7F7F"/>
            </ResourceDictionary>
        </ResourceDictionary.ThemeDictionaries>
    </ResourceDictionary>
</Application.Resources>

方法2：

正如@ jsmyth886回答

添加单独的ResourceDictionary文件并放置ResourceDictionary.ThemeDictionaries代码

<ResourceDictionary.ThemeDictionaries>
    <ResourceDictionary x:Key="Default">
        <AcrylicBrush x:Key="MyAcrylicBrush" BackgroundSource="HostBackdrop" TintColor="#FFFF0000" TintOpacity="0.8" FallbackColor="#FF7F0000"/>
    </ResourceDictionary>

    <ResourceDictionary x:Key="HighContrast">
        <SolidColorBrush x:Key="MyAcrylicBrush" Color="{ThemeResource SystemColorWindowColor}"/>
    </ResourceDictionary>

    <ResourceDictionary x:Key="Light">
        <AcrylicBrush x:Key="MyAcrylicBrush" BackgroundSource="HostBackdrop" TintColor="#FFFF0000" TintOpacity="0.8" FallbackColor="#FFFF7F7F"/>
    </ResourceDictionary>
</ResourceDictionary.ThemeDictionaries>

App.xaml中的MergedDictionaries合并了您的ResourceDictionary文件

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Dictionary1.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>
