How to fix unreadable tooltips in Eclipse Helios?

Go to Window -> Preferences -> C/C++ -> Editor Under "Appereance color options" edit your "Source hover background"


This can be solve by changing the background colour in Ubuntu. I’ve tried changing the background colour in Eclipse but it doesn’t seems to works. To change the background colour in Ubuntu, go to

System > Preferences > Appearance

enter image description here

“Appearance Preferences” panel shows up, click on “Customize…”.

enter image description here

“Customize Theme” shows up, go to “Colors” and select a lighter color for “Tooltips” Background, a darker color for “Tooltips” Text.

enter image description here

Start or restart Eclipse, you will see the the lighter colors you selected when the code-assist appears.
