Description

Display mode is for drawing a static picture.

Synopsis

Documentation

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.

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.

Possible input events.
