glutKeyboardFunc(3GLUT) GLUT glutKeyboardFunc(3GLUT)
NAME
glutKeyboardFunc - sets the keyboard callback for the current window.
SYNTAX
void glutKeyboardFunc(void (*func)(unsigned char key, int x, int y));
ARGUMENTS
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.
