glutSpecialFunc(3GLUT) GLUT glutSpecialFunc(3GLUT) NAME glutSpecialFunc - sets the special keyboard callback for the current win- dow. SYNTAX void glutSpecialFunc(void (*func)(int key, int x, int y)); ARGUMENTS func The new special callback function. DESCRIPTION glutSpecialFunc sets the special keyboard callback for the current window. The special keyboard callback is triggered when keyboard function or direc- tional keys are pressed. The key callback parameter is a GLUT_KEY_* con- stant for the special key pressed. The x and y callback parameters indicate the mouse in window relative coordinates when the key was pressed. When a new window is created, no special callback is initially registered and spe- cial key strokes in the window are ignored. Passing NULL to glutSpecial- Func disables the generation of special callbacks. During a special callback, glutGetModifiers may be called to determine the state of modifier keys when the keystroke generating the callback occurred. An implementation should do its best to provide ways to generate all the GLUT_KEY_* special keys. The available GLUT_KEY_* values are: GLUT_KEY_F1 F1 function key. GLUT_KEY_F2 F2 function key. GLUT_KEY_F3 F3 function key. GLUT_KEY_F4 F4 function key. GLUT_KEY_F5 F5 function key. GLUT_KEY_F6 F6 function key. GLUT_KEY_F7 F7 function key. GLUT_KEY_F8 F8 function key. GLUT_KEY_F9 F9 function key. GLUT_KEY_F10 F10 function key. GLUT_KEY_F11 F11 function key. GLUT_KEY_F12 F12 function key. GLUT_KEY_LEFT Left directional key. GLUT_KEY_UP Up directional key. GLUT_KEY_RIGHT Right directional key. GLUT_KEY_DOWN Down directional key. GLUT_KEY_PAGE_UP Page up directional key. GLUT_KEY_PAGE_DOWN Page down directional key. GLUT_KEY_HOME Home directional key. GLUT_KEY_END End directional key. GLUT_KEY_INSERT Inset directional key. Note that the escape, backspace, and delete keys are generated as an ASCII character.
