NAME
glutMotionFunc -- Reports mouse-motion while a button is held.
LIBRARY
OpenGLUT - input
SYNOPSIS
#include <openglut.h>
void
glutMotionFunc(void( *callback )( int x, int y ));
PARAMETERS
callback Client hook for dragging mouse.
DESCRIPTION
This function reports the mouse position when the mouse is dragged starting from within your window. (``Dragging'' occurs when you press one
or more mouse buttons in one of your OpenGLUT windows, and then move the mouse around.)
This callback is bound to the current window .
CAVEATS
Events are reported until the mouse button is released, even if the mouse leaves the window.
Windows created via glutCreateMenuWindow() always cascade keyboard and mouse events to their parent.

glutMouseFunc(3GLUT) GLUT glutMouseFunc(3GLUT)NAME
glutMouseFunc - sets the mouse callback for the current window.
SYNTAX
#include <GLUT/glut.h>
void glutMouseFunc(void (*func)(int button, int state,
int x, int y));
ARGUMENTS
func The new mouse callback function.
DESCRIPTION
glutMouseFunc sets the mouse callback for the current window. When a user presses and releases mouse buttons in the window, each press and
each release generates a mouse callback. The button parameter is one of GLUT_LEFT_BUTTON, GLUT_MIDDLE_BUTTON, or GLUT_RIGHT_BUTTON. For
systems with only two mouse buttons, it may not be possible to generate GLUT_MIDDLE_BUTTON callback. For systems with a single mouse but-
ton, it may be possible to generate only a GLUT_LEFT_BUTTON callback. The state parameter is either GLUT_UP or GLUT_DOWN indicating whether
the callback was due to a release or press respectively. The x and y callback parameters indicate the window relative coordinates when the
mouse button state changed. If a GLUT_DOWN callback for a specific button is triggered, the program can assume a GLUT_UP callback for the
same button will be generated (assuming the window still has a mouse callback registered) when the mouse button is released even if the
mouse has moved outside the window.
If a menu is attached to a button for a window, mouse callbacks will not be generated for that button.
During a mouse callback, glutGetModifiers may be called to determine the state of modifier keys when the mouse event generating the call-
back occurred.
Passing NULL to glutMouseFunc disables the generation of mouse callbacks.
