Examples for the reactive-banana library.

Core Examples

SlotMachine.hs: Mainly demonstrates how to set up an event network with your own event loop. Also demonstrates the FRP functionality.
RunPause.hs: Demonstrates how to set up an event network with your own event loop and how to pause or resume it.

GUI Examples - Very simple

Counter.hs: A simple counter that can be manipulated with two buttons "Up" or "Down". Demonstrates the accumD function.

NetMonitor.hs: Minimalistic application that displays network statistics in real time. Demonstrates the fromPoll function.

CurrencyConverter.hs: Simple currency converter. Reads and writes values to text entry widgets. (Does wxHaskell offer a way to make this real-time?) Demonstrates how to use value recursion in the NetworkDescription monad.

TwoCounters.hs: Two simple counters. There is only one pair of buttons "Up" or "Down", the button "Switch Counters" allows you to specify which counter should be affected.

GUI Examples - More elaborate

Asteroids.hs: Port of the wxAsteroids example.

Wave.hs: A wave-like pattern. Not the most beautiful code, but it demonstrates that you can generated timed events.
