如何在WPF ScrollViewer中增加滚动条宽度? [英] How to increase scrollbar width in WPF ScrollViewer?

问题描述

我正在小型设备上的触摸屏上工作，滚动条的自定义宽度不好，因为我的要求之一是一切都需要用手指手势才能完成.

I am working on a touch screen on a small device and the custom width of the scroll-bar is no good as one of my requirements is that everything needs to be doable by finger gestures.

如何设置WPF ScrollViewer滚动条的宽度?

How can I set the width of the WPF ScrollViewer scrollbar?

请注意，我不想更改设备上所有滚动条的宽度(可通过Windows设置进行更改)，仅更改应用程序中的滚动条.

Note that I don't wanna change the width of all the scrollbars on the device (doable through windows settings) - only the ones in my app.

推荐答案

ScrollBar模板可以获取系统参数以确定其宽度/高度(取决于方向).因此，您可以覆盖这些参数:

The ScrollBar template reaches out for system parameters to determine its width/height (depending on orientation). Therefore, you can override those parameters:

<ScrollViewer>
    <ScrollViewer.Resources>
        <sys:Double x:Key="{x:Static SystemParameters.VerticalScrollBarWidthKey}">100</sys:Double>
    </ScrollViewer.Resources>
</ScrollViewer>
