GLUTSPECIALFUNC(3)

NAME
glutSpecialFunc - Sets the Special callback for the current window

LIBRARY
OpenGLUT - input

SYNOPSIS
#include <openglut.h>
void
glutSpecialFunc(void( *callback )( int key, int x, int y ));

PARAMETERS

callback Client function for keyboard event.

DESCRIPTION
Registers a callback for OpenGLUT to call when the user presses "special" keys on the keyboard.

The special callback handles some additional keys that are not covered under plain "keyboard" events. The key that is passed to the callback is one of an enumerated set. The association to keys on your keyboard should be obvious. Their GLUT symbol names are:

- GLUT_KEY_F1

- GLUT_KEY_F2

- GLUT_KEY_F3

- GLUT_KEY_F4

- GLUT_KEY_F5

- GLUT_KEY_F6

- GLUT_KEY_F7

- GLUT_KEY_F8

- GLUT_KEY_F9

- GLUT_KEY_F10

- GLUT_KEY_F11

- GLUT_KEY_F12

- GLUT_KEY_LEFT

- GLUT_KEY_UP

- GLUT_KEY_RIGHT

- GLUT_KEY_DOWN

- GLUT_KEY_PAGE_UP

- GLUT_KEY_PAGE_DOWN

- GLUT_KEY_HOME

- GLUT_KEY_END

- GLUT_KEY_INSERT

To receive other keys, see glutKeyboardFunc().

This callback is bound to the current window .

CAVEATS
Many keys are not included; nor is it possible to apply qualifiers such as the Shift or Ctrl key to these keys.

Windows created via glutCreateMenuWindow() always cascade keyboard and mouse events to their parent.
