在不丢失悬停颜色的情况下更改超链接前景 [英] Changing Hyperlink foreground without losing hover color

问题描述

我正在编写一个 WPF 应用程序，我希望我的一些超链接默认为蓝色，而其他超链接为绿色.没问题——我可以设置 Foreground:

I'm writing a WPF app, and I want some of my hyperlinks to be the default blue, and others to be green. No problem -- I can just set Foreground:

<TextBlock><Hyperlink Foreground="#0C0">Mark as done</Hyperlink></TextBlock>

问题是，当我这样做时，悬停效果消失了.在普通的超链接中，当我将鼠标移到链接上时，它会变成红色，而当我将鼠标移开时，它会变回蓝色.但是在分配了 Foreground 属性的超链接中，它始终是那种颜色——悬停时的红色完全被抑制.

The trouble is, when I do this, the hover effect goes away. In a normal Hyperlink, when I move the mouse over the link, it turns red, and when I move the mouse away, it goes back to blue. But in a Hyperlink with the Foreground property assigned, it's always that color -- the red-on-hover is totally suppressed.

如何在不丢失默认悬停行为和颜色的情况下更改超链接的颜色?

How can I change a Hyperlink's color, without losing the default hover behavior and color?

推荐答案

直接设置前景(正如您所做的那样)不起作用，并且在样式中设置它也不起作用，除非 您从默认的超链接样式(必须包括 OnMouseOver 触发器)派生"该样式.所以这是有效的:

Setting the Foreground directly (as you've done) doesn't work, and setting it in a Style doesn't work either, unless you "derive" that style from the default Hyperlink style (which must include the OnMouseOver trigger). So this works:

<TextBlock>
    <Hyperlink>
        <Hyperlink.Style>
            <Style TargetType="Hyperlink"
                   BasedOn="{StaticResource {x:Type Hyperlink}}">
                <Setter Property="Foreground" Value="#0C0"/>
            </Style>
        </Hyperlink.Style>
        Mark as done
    </Hyperlink>
</TextBlock>

将该样式提取回 Window 资源并使用键引用它可能会使 XAML 更具可读性，但上面的代码可以完成这项工作.

Extracting that style back into the Window resources and referencing it with a key would probably make for more-readable XAML, but the above code does the job.
