Eclipse, change popup text background color when hovering the mouse on a keyword

eclipseubuntu-10.04

提问by e2-e4

Ubuntu 10.04.1 new theme has by default all windows background colors set to black.
I don't want to change that.

Ubuntu 10.04.1 新主题默认将所有窗口背景颜色设置为黑色。
我不想改变这一点。

In Eclipse, the interface didn't change much due to 10.04.1 - except for one annoying thing:
when the mouse hovers over a keyword - a variable for instance - the type (...) of that keyword is displayed in a small pop-up window.
The problem since 10.04.1, is that the text is in blackcolor while the background is alsoblack.

在 Eclipse 中，由于 10.04.1，界面没有太大变化 - 除了一件烦人的事情：
当鼠标悬停在一个关键字上时 - 例如一个变量 - 该关键字的类型 (...) 显示在一个小的弹出窗口。
自 10.04.1 以来的问题是文本是黑色的，而背景也是黑色的。

Is there a way to change that background color in Eclipse?

有没有办法在 Eclipse 中更改该背景颜色？

Update Dec. 2018: as mentioned in howlger's answer, Eclipse Oxygen 4.7 (June 2017)does now include a way to configure the background color in popups:

2018 年 12 月更新：如howlger的回答中所述，Eclipse Oxygen 4.7（2017 年 6 月）现在确实包含一种在弹出窗口中配置背景颜色的方法：

See "Colors in interactive popups"

请参阅“交互式弹出窗口中的颜色”

Interactive popups like JDT's Quick Outline don't use the platform's tooltip colors any more, since those were sometimes hard to read.

像 JDT 的 Quick Outline 这样的交互式弹出窗口不再使用平台的工具提示颜色，因为它们有时难以阅读。

  • Go to Window > Preferences: General > Appearance > Colors and Fonts
  • and change the Basic > Information backgroundcolor.
  • 去 Window > Preferences: General > Appearance > Colors and Fonts
  • 并改变Basic > Information background颜色。

In that same Colors and Fontssection, you will find:

在同Colors and Fonts一部分，您会发现：

  • Code assist

    • Basic > Content Assist background color-> change
    • Basic > Content Assist foreground color-> change

  • java doc

    • Java > Javadoc background( overrides default: information background color) -> change

  • 代码辅助

    • Basic > Content Assist background color-> 改变
    • Basic > Content Assist foreground color-> 改变

  • 文档

    • Java > Javadoc background（覆盖默认值：信息背景颜色）-> 更改

Original answer (2010-2012)

原始答案（2010-2012）

All the various popup background color are managed in Preferences > Java > Editor(like the one for the completion list popup in bug 133615).
Other background colors are in General > Appearance > Colors and Font(type backgroundin the filter field).

所有各种弹出式背景颜色都在Preferences > Java > Editor其中进行管理（例如bug 133615 中的完成列表弹出式背景颜色）。
其他背景颜色在General > Appearance > Colors and Font（background在过滤器字段中输入）。

But the type popup seems to stick to a system color, which is why you see a black background.
If this is truly the case, it is worth reporting as a bug.

但是类型弹出窗口似乎坚持系统颜色，这就是您看到黑色背景的原因。
如果情况确实如此，则值得报告为错误。

The OP confirms it is not the case, actually:

OP 确认事实并非如此，实际上：

It was in Preferences > C/C++ > Editor > Source hover background, and had to untick the "System default" (because the shown color was light-gray!)

它在 中Preferences > C/C++ > Editor > Source hover background，并且必须取消勾选“系统默认值”（因为显示的颜色是浅灰色！）

On Ubuntu 12.04+, the post "How to change tooltip background color in Unity?" also mentions:

在 Ubuntu 12.04+ 上，帖子“如何在 Unity 中更改工具提示背景颜色？”还提到：

/usr/share/themes/Ambiance/gtk-2.0/gtkrc

The recent post (December 2012) "Eclipse Papercut #10 – Eclipse on Ubuntu: Fixing the black background color in hover" (from Lars Vogel) confirms:

最近的帖子（2012 年 12 月）“ Eclipse Papercut #10 – Ubuntu 上的 Eclipse：在悬停中修复黑色背景色”（来自Lars Vogel）证实：

The relevant properties are tooltip_fg_colorand tooltip_bg_color.
Just search for these values, the position changes sometimes between releases, currently they are at the very top of the file.

The following setting uses more reasonable colors.

相关属性是tooltip_fg_color和tooltip_bg_color。
只需搜索这些值，位置有时会在版本之间发生变化，目前它们位于文件的最顶部。

下面的设置使用了更合理的颜色。

tooltip_fg_color:#000000
tooltip_bg_color:#f5f5c5

pointhi在评论中补充道：

I also had to set the environment variable SWT_GTK3=0before starting eclipse to get it working.

我还必须SWT_GTK3=0在启动 eclipse 之前设置环境变量才能使其工作。

If you use KDE (Kubuntu) you can fix that by changing the Tooltip Background color in KDE System Settings -> Application Appearance -> Colors -> Colors, and change the Tooltip Background.

如果您使用 KDE (Kubuntu)，您可以通过在 KDE 系统设置 -> 应用程序外观 -> 颜色 -> 颜色中更改工具提示背景颜色并更改工具提示背景来解决该问题。

I've adopted a slightly different solution;

我采用了一个稍微不同的解决方案；

First create a new script, eclipse.sh, that starts eclipse, mine look like this:

首先创建一个新脚本 eclipse.sh，它启动 eclipse，我的看起来像这样：

#!/bin/bash
GTK2_RC_FILES=/usr/share/eclipse/gtkrc-2.0-eclipse /usr/share/eclipse/eclipse

Then create the gtkrc file (/usr/share/eclipse/gtkrc-2.0-eclipse), mine look like this (it have some other changes as well to make better use of the screen):

然后创建 gtkrc 文件（/usr/share/eclipse/gtkrc-2.0-eclipse），我的看起来像这样（它还有一些其他更改以更好地利用屏幕）：

style "my-tooltips"
{
  bg[NORMAL] = "#FFFFAF"
  fg[NORMAL] = "#000000"
}
widget "gtk-tooltip*" style "my-tooltips"

style "gtkcompact" 
{
    font_name="Ubuntu Light 11"

    GtkButton::default_border={0,0,0,0}
    GtkButton::default_outside_border={0,0,0,0}
    GtkButtonBox::child_min_width=0

window -> preferences -> general -> Appearance -> Color&Fonts -> Java (necessary language, example java) -> Javadoc text color (or Javadoc background)

窗口 -> 首选项 -> 常规 -> 外观 -> 颜色&字体 -> Java（必要语言，示例 java） -> Javadoc 文本颜色（或 Javadoc 背景）

回答by howlger

Since Eclipse Oxygen (4.7) this color can be configured in Window > Preferences: General > Appearance > Colors and Fontsby changing the Basic > Information background color.

从 Eclipse Oxygen (4.7) 开始，可以通过更改Basic > Information background color在Window > Preferences: General > Appearance > Colors and Fonts 中配置这种颜色。
