Constructor Details

#initialize(a, string) ⇒ FXFont

Construct a font with given font description of the form:

 fontname [ "[" foundry "]" ] ["," size ["," weight ["," slant ["," setwidth ["," encoding ["," hints]]]]]]

For example:

 "helvetica [bitstream],120,bold,italic,normal,iso8859-1,0"

Typically, at least the font name, and size must be given for normal font matching. As a special case, raw X11 fonts can also be passed, for example:

 "9x15bold"

Note: use of the raw X11 fonts is stronly discouraged.
