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

GUI Examples - Very simple

Arithmetic.hs

Minimalistic calculator that can add two numbers. Demonstrates how to read values from text entries and respond to button clicks.

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 in real-time. Demonstrates how to use value recursion in the NetworkDescription monad.

GUI Examples - More elaborate

Asteroids.hs

Port of the wxAsteroids example.

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.

A version of TicTacToe with eclectic interface elements, courtesy of Gideon Sireling.

Wave.hs

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