    • getDefaultGenericFontFamily

      public String getDefaultGenericFontFamily(String genericFamily)
      Gets the name of the default font used when a generic font family (serif, sans-serif, monospace, cursive, fantasy) is specified.

      This class attempts to map the generic name to a "logical font" name.

      As, in Java, logical font names are internally mapped to physical fonts by the Java runtime environment, the name of the corresponding "logical font" is returned, and no further mapping is attempted.

      Parameters:
      genericFamily - the name of the logical font.
      Returns:
      the name of the associated logical font, or null if none.
