Eclipse uses the fonts and colors provided by the operating system as much as possible. On Windows the platform color and font settings are found on the Preferences > Colors and Fonts page. The font used by most widgets in Eclipse is the one set in the Message Box settings of the properties. However, operating systems do not provide enough colors to handle all of the extra information that colors and fonts provide in Eclipse.
There are 4 main fonts in use by the Eclipse platform. They are:
These fonts can be set via the
General > Appearance > Colors and Fonts preference page.
As well as these 4 fonts there are several other secondary font settings. These
default to the text font. They can be found on the Colors and Fonts preference
page:
Eclipse uses colors as an information enhancement in many places. Whenever possible the operating system color settings are used, but in cases where the operating system settings are not enough, Eclipse defines other colors. All of these colors can be adjusted via the following preference pages:
General > Appearance > Colors and Fonts > Basic (Error text, hyperlink
text, active hyperlink text)
General > Search (Foreground for potential matches)
Run/Debug > Console (Standard Out, Standard Error, Standard In)
Run/Debug (Variable Views changed value, Memory View unbuffered lines)
Ant (Error, Warning, Information, Verbose, Debug)
Java > Editor (Line number, matching brackets, current line,
print, find scope, hyperlink, selection foreground, selection background)
Java > Editor > Syntax Coloring (Javadoc HTML tags,
Javadoc keywords, Javadoc links, Javadoc others, keyword 'return', keywords
excluding 'return', Method names, Multi line comment, Operators and brackets,
Others, Single-line comment, Strings, Task Tags)
Plug-in Development > Editors (Text, Processing instructions,
Constant strings, Tags, Comments)
Team > CVS > Console (Command line, Message, Error)
Accessibility
and the Windows Color DialogFor color selection, Eclipse uses a dialog provided by the operating system. On windows, the color selection dialog does not respond properly to assistive technology. When you first get into the dialog, focus is on one of the basic colors, but the dialog provides no indication of this through assistive technology. You can select colors in Eclipse with this dialog in the following way:
