如何更改 MySQL Workbench 编辑器背景颜色？它似乎总是白色。我使用的是 Workbench 版本 6.3.7。
注意：其他 Stack 帖子中也提供了如何执行此操作的描述，但我尝试过的那些都没有用。事实上，有些说明已经过时，不再包含以前版本所具有的 XML 样式元素。
我正在查看 code_editor.xml（在我的 PC 上，它位于：C:\Program Files\MySQL\MySQL Workbench 6.3 CE\data），我看到了一些有趣的部分，例如：
<style id="1" fore-color="#008C3A" /> <!-- SCE_MYSQL_COMMENT -->
<style id="2" fore-color="#008C3A" /> <!-- SCE_MYSQL_COMMENTLINE -->
<style id="21" fore-color="#F77B09" back-color="#F0F0F0" /> <!-- SCE_MYSQL_HIDDENCOMMAND -->

<style id="18" fore-color="#007F00" /> <!-- SCE_MYSQL_USER1 -->
<!-- All styles again in their variant in a hidden command (with a 0x40 offset). -->
<style id="65" fore-color="#A0A0A0" back-color="#F0F0F0" /> <!-- SCE_MYSQL_COMMENT -->
<style id="66" fore-color="#A0A0A0" back-color="#F0F0F0" /> <!-- SCE_MYSQL_COMMENTLINE -->

<style id="82" fore-color="#007F00" /> <!-- SCE_MYSQL_USER1 -->
但我不知道其中哪一个（如果有的话）会简单地改变查询编辑器的背景颜色。提前致谢。
答案1
编辑器使用 Scintilla，并正如您所猜测的那样通过文件 data/code_editor.xml 进行配置。
该文件由语言组成，每种语言都必须定义样式。
要更改文本背景，请使用 ID 32 (STYLE_DEFAULT)
例子：
<style id="32" back-color="#000000" /> <!-- STYLE_DEFAULT -->
左侧的行号背景可通过 id 33（STYLE_LINENUMBER）进行自定义
其他样式 id 适用于不同的关键字（code_editor.xml 注释中描述）。例如：可以通过back-color在语言 SCLEX_MYSQL 上添加 id 1 和 2 来更改注释背景。
对于您想要定制的每种语言，都必须这样做。
据我所知，没有办法全局更改默认设置。

取自这里但我对其进行了更改，以便它可以在 Windows 10 上的 MySQL Workbench 8.0 中运行。由于据我所知 MacOS 已经集成了暗黑模式，所以不需要它。
将以下内容复制到code_editor.xml末尾。您可以在安装 Workbench 的任何<language name="SCLEX_MYSQL">位置或位置找到此文件。C:\Program Files\MySQL\MySQL Workbench 8.0 CE\data

您还可以在 Workbench 中将方案更改为Windows 7下方Edit -> Preferences -> Fonts & Colors，以使一些额外元素比默认值稍暗（至少对我来说）。
