Changing colors, fonts, and more in the Code editor and Code view

The Code editor and Code view are Eclipse text editors, so you can customize their appearance using the preferences in General - Editors - Text Editors. There are also additional preferences available in General - Appearance - Colors and Fonts. Since you use the Code editor and Code view for editing C++ code, the preferences under C/C++ - Editor also apply. You can set the font to be used in the preferences.
