FRP.Rhine.Gloss.Pure

Description

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.

Synopsis

data GlossM a
paint :: Picture -> GlossM ()
clear :: GlossM ()
paintAll :: Picture -> GlossM ()
data GlossClock = GlossClock
type GlossClSF = ClSF GlossM GlossClock () Picture
currentEvent :: ClSF GlossM GlossClock () (Maybe Event)
flowGloss :: (Clock GlossM cl, GetClockProxy cl) => GlossSettings -> Rhine GlossM cl () () -> IO ()
flowGlossClSF :: GlossSettings -> GlossClSF -> IO ()

Documentation

data GlossM a Source #

A pure monad in which all effects caused by the gloss backend take place.

paint :: Picture -> GlossM () Source #

Add a picture to the canvas.

clear :: GlossM () Source #

Clear the canvas.

paintAll :: Picture -> GlossM () Source #

Clear the canvas and then paint.

data GlossClock Source #

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 GlossClSF = ClSF GlossM GlossClock () Picture Source #

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) Source #

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

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

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

flowGlossClSF Source #

Arguments

:: GlossSettings
-> GlossClSF	The `gloss`-compatible `ClSF`.
-> IO ()

Specialisation of flowGloss to a GlossClSF
