## Name

glutKeyboardFunc — sets the keyboard callback for the current window.

## C Specification

`void `glutKeyboardFunc`` | `(` | `void (*`func`)(unsigned char key, int x, int y));`

## Python Specification

``glutKeyboardFunc`` | `(` | ``func`) → `None``

## Parameters

`func`
  The new keyboard callback function.

## Description

`glutKeyboardFunc` sets the keyboard callback for the current window. When a user types into the window, each key press generating an ASCII character will generate a keyboard callback. The key callback parameter is the generated ASCII character. The state of modifier keys such as Shift cannot be determined directly; their only effect will be on the returned ASCII data. The x and y callback parameters indicate the mouse location in window relative coordinates when the key was pressed. When a new window is created, no keyboard callback is initially registered, and ASCII key strokes in the window are ignored. Passing `NULL` to `glutKeyboardFunc` disables the generation of keyboard callbacks.

During a keyboard callback, `glutGetModifiers` may be called to determine the state of modifier keys when the keystroke generating the callback occurred.

Use `glutSpecialFunc` for a means to detect non-ASCII key strokes.
