Description

Implements functions to open windows and draw pictures in them.

Synopsis

displayInWindow :: String -> (Int, Int) -> (Int, Int) -> Picture -> IO ()

animateInWindow :: String -> (Int, Int) -> (Int, Int) -> (Float -> Picture) -> IO ()

renderInWindow :: String -> (Int, Int) -> (Int, Int) -> (IORef DisplayState -> IO ()) -> Bool -> IO ()

callbackDisplay :: IORef DisplayState -> (IORef DisplayState -> IO ()) -> IO ()

Documentation

displayInWindow

:: String	Name of the window.
-> (Int, Int)	Initial size of the window, in pixels.
-> (Int, Int)	Initial position of the window, in pixels relative to the top left corner of the screen.
-> Picture	The picture to draw.
-> IO ()
Opens a window and displays a static picture.

animateInWindow

:: String	Name of the window.
-> (Int, Int)	Initial size of the window, in pixels.
-> (Int, Int)	Initial position of the window, in pixels relative to the top left corner of the screen.
-> (Float -> Picture)	New frame function. The function is passed the current animation time, in seconds.
-> IO ()
Opens a window and displays an animation.

renderInWindow

:: String	Name of the window.
-> (Int, Int)	Initial size of the window, in pixels.
-> (Int, Int)	Initial position of the window, in pixels relative to the top left corner of the screen.
-> (IORef DisplayState -> IO ())	The function to call to draw the frame.
-> Bool	Whether to animate the picture.
-> IO ()
Opens a window and calls a user supplied function to draw frames for animation. Timing and event information can be obtained from the display state which is passed to the user function at each call.

callbackDisplay

:: IORef DisplayState	The current state.
-> (IORef DisplayState -> IO ())	The user's display function.
-> IO ()
GLUT calls back on this function when it's time to draw a new frame. It sets up the render state, calls the user's display function and manages display timings.

callbackReshape

:: IORef DisplayState	The current state.
-> Size	New window size.
-> IO ()
GLUT calls back on this function when the window size changes. It configures the new viewport and writes the new size into the state.
