RichTextBox 中所选文本的颜色 [英] Color of selected text in RichTextBox

问题描述

在 CSS 中，我们可以使用 ::selection 伪标签来编辑文本选择的颜色.是否可以只为一个控件覆盖选择的默认背景颜色，例如富文本框?我知道，无法通过 CSS 之类的方式更改默认行为，但至少可以为此控件覆盖它.

In CSS we're able to edit the text selection's colors by using the ::selection pseudo-tag. Is it possible, to overwrite the default background color of the selection just for one control, e.g. a RichTextBox? I know, that there is no way to change the default behaviour by something like CSS, but at least overwrite it for this control might be possible.

我已经用谷歌搜索了大约一个小时，但我只找到了语法高亮的片段.我希望文本是例如黄色而不是典型的 Windows 蓝色.

I already googled for about an hour now, but I only found snippets of syntax highlighting. I want the text to be e.g. yellow instead the typical Windows blue.

推荐答案

在 WPF 中，您可以按如下方式完成:

In WPF you can accomplish this as follows:

myRichTextBox.SelectionBrush = System.Windows.Media.Brushes.Yellow; // WPF
myRichTextBox.IsInactiveSelectionHighlightEnabled = true;

不幸的是，在 Windows 窗体中无法实现所需的行为(详细信息 此处).解决方法是通过 ElementHost.

Unfortunately, the desired behavior is not possible in Windows Forms (details here). The workaround would be to use a WPF RichTextBox in the Windows Form through ElementHost.

删除了 WinForms 解决方案，因为 SelectionBackColor 没有提供所需的行为.

Removed the WinForms solution, because SelectionBackColor does not provide the desired behavior.
