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 win-dow, window,
dow, 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 deter-mined determined
mined 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 win-dow window
dow 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.
