Description

Produce events on a Kafka topic from GLUT callbacks <https://hackage.haskell.org/package/GLUT-2.7.0.10/docs/Graphics-UI-GLUT-Callbacks-Window.html>.

Synopsis

data GlutCallback
- = KeyboardMouse
- | Motion
- | PassiveMotion
- | Spaceball
- | Joystick
glutLoop :: TopicConnection -> Sensor -> [GlutCallback] -> IO (ExitAction, LoopAction)
interpretKeyboardMouse :: Key -> KeyState -> Modifiers -> Position -> Event
interpretMotion :: Position -> Event
interpretSpaceball :: SpaceballInput -> Event
interpretJoystick :: JoystickButtons -> JoystickPosition -> Event
setCallbacks :: [GlutCallback] -> (Event -> IO ()) -> IO ()
clearCallbacks :: [GlutCallback] -> IO ()

Event handling.

data GlutCallback Source #
