Documentation

module Graphics.Gloss.Data.Display

module Graphics.Gloss.Data.Picture

module Graphics.Gloss.Data.Color

interactIO

Arguments

:: Display

Display mode.

-> Color

Background color.

-> world

Initial world state.

-> (world -> IO Picture)

A function to produce the current picture.

-> (Event -> world -> IO world)

A function to handle input events.

-> (Controller -> IO ())

Callback to take the display controller.

-> IO ()

Open a new window and interact with an infrequently updated picture.

Similar to displayIO, except that you manage your own events.

data Controller

Functions to asynchronously control a Gloss display.

Constructors

Controller

Fields

• controllerSetRedraw :: IO ()

  Indicate that we want the picture to be redrawn.

• controllerModifyViewPort :: (ViewPort -> IO ViewPort) -> IO ()

  Modify the current viewport, also indicating that it should be redrawn.

data Event

Possible input events.
