更改超链接前景而不会丢失悬停颜色 [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是默认的蓝色，其他的是绿色。没问题 - 我可以设置前景：

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>

麻烦的是，当我这样做时，悬停效果消失了。在普通的超链接中，当我将鼠标移动到链接上时，它会变为红色，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 - 完全抑制了红色悬停。

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.

如何更改超链接的颜色丢失默认的悬停行为和颜色？

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

推荐答案

直接设置Foreground（正如你所做的那样）不起作用，将它设置为样式也不起作用，除非您从默认的超链接样式（必须包含OnMouseOver触发器）派生该样式。所以这样做：

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资源并使用密钥引用它可能会使更具可读性XAML，但上面的代码完成了这项工作。

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.
