To load this example and for sample queries, please see the `SCRIPT.txt`
file. Running all the examples and the benchmarks requires XVM (with its
`jni` plug-in installed) or SWI-Prolog (with the JPL library installed).
YAP most likely would be usable when the old JPL library bundled with it
is updated. Some examples (but not the benchmarks) can also be used with
JIProlog.

This folder contains GUI examples, most of them adapted from the JPL library
distributed with SWI-Prolog and YAP, of calling Java from Logtalk. It uses
a lightweight abstraction included in the Logtalk library for calling Java.

Adaptations of the JColorChooser and JOptionPane dialog examples and the
JTable example from the JPL distribution are included.

When running the GUI examples on the macOS Terminal application, you may
get a Java error saying that the AWT cannot be started. In alternative, try
to run the example from within the SWI-Prolog macOS application instead
of using the shell integration script. This issue is due to a macOS Java
issue that's orthogonal to both SWI-Prolog/YAP and Logtalk.
