Description

FLTK manages fonts via an array indexed by small integers. Font provides named fonts and functions to manipulate the font array.

Detailed reference

Font:get_font_name(Font f): string name, Font emphasis

Get a human-readable string describing the family of this face. This is useful if you are presenting a choice to the user. There is no guarantee that each face has a different name.

The emphasis returned is 0, Font.bold, Font.italic or Font.bold+Font.italic. To locate a "family" of fonts, search forward and back for a set with non-zero attributes; these faces along with the face with a zero attribute before them constitute a family.

Font:set_fonts(string name): integer

FLTK will open the display, and add every font on the server to the face table. It will attempt to put "families" of faces together, so that the normal one is first, followed by bold, italic, and bold italic.

The optional argument is a string to describe the set of fonts to add. Passing nil will select only fonts that have the ISO8859-1 character set (and are thus usable by normal text). Passing "-*" will select all fonts with any encoding as long as they have normal X font names with dashes in them. Passing "*" will list every font that exists (on X this may produce some strange output). Other values may be useful but are system dependent. With WIN32 nil selects fonts with ISO8859-1 encoding and non-nil selects all fonts.

The return value is how many faces are in the table after this is done.
