How to fix black tooltips in Eclipse?

I am having a weird problem with Eclipse documentation tooltips. When I startup Eclipse the tooltip works as expected:

But after I press the down button the tooltip turns black:

and stays like that for the rest of the session.

I am using Eclipse Galileo and Ubuntu 11.04 with the classic desktop.

EDIT: I am only experiencing this problem in PHP Development Tools. The tooltips work in Java and Python projects.

Solution 1:

The answer from Arkaduysz's works if you correct the second line. the gksu would try to change root's settings I think.:

Install:

sudo apt-get install gnome-color-chooser 

run it:

gnome-color-chooser 

Go to "Specific" tab, check and setup background/foreground colors in tooltip box. Apply & Close.

To fix the color issue in the eclipse package explorer (white font on light grey back), choose "global" tab, and check standard > inputfield > selected and set it to black.

Solution 2:

To fix this annoying behaviour in KDE, the fix is similar:

• run System Settings
• Click on Application Appearance in Common Appearance and Behaviour
• Click on Colours icon and then on Colours tab
• Find Tooltip Background and choose a bright color, for instance pale yellow or white
• Find Tooltip Text below and choose a darker color, like blue or black
• Click Apply

The fix will be available immediately, no need to restart Eclipse.

Note: On Eclipse mars the change was not immediate. I had to restart eclipse.

Solution 3:

Install:

sudo apt-get install gnome-color-chooser 

run it:

gnome-color-chooser 

Go to "Specific" tab, check and setup background/foreground colors in tooltip box. Apply & Close.
