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.

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 Source #

Arguments

:: GlossSettings 
-> GlossClSF

The gloss-compatible Rhine.

-> IO () 

The main function that will start the gloss backend and run the SN (in the case of the combined clock).

flowGlossWithWorldMSF :: Clock GlossM cl => GlossSettings -> cl -> MSF GlossM (Time cl, Tag cl) b -> IO () Source #
