FRP.Rhine.Gloss.Pure

A pure gloss backend for Rhine.

To run pure Rhine apps with gloss, write a clocked signal function (ClSF) in the GlossClock and use flowGloss.

Documentation

Add a picture to the canvas.

clear :: GlossM ()

Clear the canvas.

data GlossClock

The overall clock of a pure rhine ClSF that can be run by gloss. It ticks both on events (tag = Just Event) and simulation steps (tag = Nothing).

type Time GlossClock = Float

type GlossClSF = ClSF GlossM GlossClock () Picture

The type of a ClSF you can implement to get a gloss app, if you chose to handle events and simulation steps in the same subsystem.

You can, but don't need to paint via GlossM: You can also simply output the picture and it will be painted on top.

currentEvent :: ClSF GlossM GlossClock () (Maybe Event)

Observe whether there was an event this tick, and which one.

flowGloss :: (Clock GlossM cl, GetClockProxy cl) => GlossSettings -> Rhine GlossM cl () () -> IO ()

The main function that will start the gloss backend and run the Rhine

flowGlossClSF

Arguments

:: GlossSettings

-> GlossClSF

The gloss-compatible ClSF.

-> IO ()

Specialisation of flowGloss to a GlossClSF
