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 button, 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 callback occurred.
Passing
NULL
to
glutMouseFunc
disables the generation of mouse callbacks.
