Under the Ambiance theme, the tip popped up by eclipse has a black background, which makes it impossible to see the java doc at all.
Of course, you can change the system theme to other themes in the appearance. The corresponding gtk-2.0/gtkrc needs to be reset. For example, the default theme of Ubuntu 12.04 is Ambiance, then we can change the following path to: /usr/share/themes/Ambiance/gtk -2.0
Solution:
cd /usr/share/themes/Ambiance/gtk-2.0
sudo gedit gtkrc
The relevant code is as follows: (I modified it)
gtk-color-scheme = "base_color:#C7EDCC\n
fg_color:#4c4c4c\n
tooltip_fg_color:#000000\n
selected_bg_color:#fff0f5\n
selected_fg_color:#FF6600\n
text_color:#3C3C3C\n
bg_color:#f6f4f2\n
tooltip_bg_color:#f2edbc\n
link_color:#DD4814"
in:
base_color is the base color, I adjusted it to bean paste green #C7EDCC, so that the main color of the entire eclipse is bean paste green, to protect the eyes.
tooltip_fg_color : It is the tip that pops up by pointing the mouse to a variable in eclipse, and there is a java doc in it. This is the foreground color, such as the font color.
tooltip_bg_color: The background color, which was originally black, caused the doc to be unclear, so it can be changed to a lighter color.
selected_bg_color: The selected background color, the original background is too dark, the selected words are not clear, it is recommended to modify.
selected_fg_color: The selected foreground color, such as the font color.
