glutKeyboardFunc(3GLUT) GLUT glutKeyboardFunc(3GLUT)NAMEglutKeyboardFunc - sets the keyboard callback for the current window.
SYNTAX
#include <GLUT/glut.h>
void glutKeyboardFunc(void (*func)(unsigned char key,
int x, int y));
ARGUMENTS
func The new keyboard callback function.
DESCRIPTIONglutKeyboardFunc 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.
