FOX now supports anti-aliased fonts, by way of Xft2, Fontconfig, and FreeType 2.

Xft2 support is not automatically enabled at this time. To enable Xft2 support for a particular build of the FOX library, you should pass the --with-xft=yes flag on the configure command line, e.g.

$ ./configure --with-xft=yes

According to the FAQ at the FOX Community Wiki, FOX doesn't automatically choose an anti-aliased font as the default application font, even if you've built FOX with Xft2 support enabled. You can get around this by editing the ~/.foxrc/Desktop file; this is the file in which all of the application-wide settings for FOX applications are defined. If this file doesn't exist yet, you will be creating it. Create (or add) a section like this to your Desktop file:

[SETTINGS]
normalfont="Sans,90"

This setting instructs FOX to try to use a Sans Serif font of size 90 decipoints (or 9 points) as its normal font. If FOX still fails to pick a smooth font after changing this setting, pick a more specific font name, such as "Bitstream Vera Sans".
