glutKeyboardFunc man page

glutKeyboardFunc — Sets the Keyboard callback for the current window.

Library

OpenGLUT - input

Synopsis

#include <openglut.h>

void
glutKeyboardFunc(void( * callback )( unsigned char key, int x, int y ));

Parameters


callback


Client function for keyboard event.

Description

This callback registration allows you to handle traditional ASCII keyboard input. A general rule of thumb is that if a key has a common ASCII code, then OpenGLUT assigns that code to the key and calls the Keyboard


callback


with the ASCII code in the


key


parameter. For other keys, you must use glutSpecialFunc(). Not all keys can be reported by OpenGLUT.

As a convenience, the mouse coordinates, relative to your window, are also returned.

This callback is bound to the


current window


.

Caveats

This function is not very international-friendly.

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