To be honest about how to handle the black background of eclipse in ubuntu 11.10, ubuntu testing is not very powerful in terms of development tool support, which is a little less attractive for developers. Go to the topic! In ubuntu versions, the background of the eclipse prompt is black, which almost affects usage. This includes the javadoc bubble display and the inspect and other pop-up boxes during debugging. You can search for ubuntu eclipse black on google to find many related posts and solutions. But neither version 11.10 nor eclipse CDT. Because I developed it in java, JDT could not verify the CDT solution, and I could not solve it normally, so that I have installed the advance setting application of ubuntu and it has not been solved. Later I found a solution in the English Forum. Thank God. If not, I may switch back to windows. Www.2cto.com knows that the solution is really simple, that is, to modify the tooltip background color of the system topic! The path is in the/usr/share/themes/topic. The default path is the gtkrc file in the gtk-2.0 folder under Ambiance. Find tooltip_fg_color: # ffffff and change # ffffff to another color. Start happy encoding! /Usr/share/themes/Ambiance/gtk-2.0 later do not too superstitious Chinese! Author yq76034150
