There are 6 internal fonts that are always available in a graphical host system:

These fonts are mapped to Java logical fonts by default. Java logical fonts are the five font families defined by the Java platform which must be supported by any Java runtime environment: Serif, SansSerif, Monospaced, Dialog, and DialogInput. These logical fonts are not actual font libraries. Instead, the logical font names are mapped to physical fonts by the Java runtime environment.

You can map them to different fonts installed in the system by setting the following configuration properties:

The handles to these fonts are defined in the isfonts.def copybook.

In addition to the above internal fonts you can load other fonts from the underlying host sytem and from disc files.

To load a font from the underlying host system, use the WFONT-GET-FONT function.

To load a font from a disc file, use the W$CREATEFONT routine and then the WFONT-GET-FONT function.

If the load is successful, the WFONT-GET-FONT returns a handle to the font that you can use with graphical controls properties.
