This package contains a collection of examples using Grapefruit.

run UIBackend mainCircuit ()

Replace Example with the name of the example to run and UIBackend with the name of the UI backend you want to use. At the moment, the only examples are Simple, Switching, Converter, ListView, and SetView, and the only UI backend is GTK.
