Examples for the reactive-banana library.

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.

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.

CRUD.hs: A toy CRUD (Create/Read/Update/Destroy) application. Demonstrates how to do incremental updates. Of course, this makes the code quite messy, but I think it's still pretty nice. For instance, it was quite easy to add the filter box.

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