[UWP] [XAML]使用ScrollBar / ScrollViewer的拇指颜色

问题描述

如何尽可能轻松地改变ScrollBar / ScrollViewer拇指的颜色（滚动的东西）？

How can I easily with as little effort as possible change the color of the ScrollBar/ScrollViewer thumb (the thingy that gets scrolled)?

我已经尝试了所有的解决方案我在网上发现它根本不起作用。

I already tried out all solutions I found online and it simply doesn't work.

我不敢相信这不是一个简单的刷子...它没有任何意义。

I cannot believe this isn't implemented to be a simple Brush... It doesn't make any sense.

推荐答案

如果你的应用程序的最小目标版本是14393+，你将会是能够通过仅使用x：Key =" ScrollBarThumbFill *"来改变Thumb颜色。在参考资料中。

If your app's min target version is 14393+, you would be able to change Thumb color by just putting some Brushes with x:Key="ScrollBarThumbFill*" in Resources.

    <ScrollViewer>
        <ScrollViewer.Resources>
            <SolidColorBrush x:Key="ScrollBarThumbFill" Color="Gold"/>
            <SolidColorBrush x:Key="ScrollBarThumbFillPointerOver" Color="Orange"/>
            <SolidColorBrush x:Key="ScrollBarThumbFillPressed" Color="Red"/>
            <SolidColorBrush x:Key="ScrollBarThumbFillDisabled" Color="Pink"/>
        </ScrollViewer.Resources>

        <Rectangle Width="512" Height="2048">
            <Rectangle.Fill>
                <LinearGradientBrush>
                    <GradientStop Color="Orange"/>
                    <GradientStop Color="MidnightBlue" Offset="1"/>
                </LinearGradientBrush>
            </Rectangle.Fill>
        </Rectangle>
    </ScrollViewer>
