16 callback Client hook for mouse-buttons.

19 Whenever a mouse button is pressed or released in an OpenGLUT window,
20 OpenGLUT checks if that window has a mouse-button (Mouse) callback regis‐
21 tered. If so, OpenGLUT gives the event to the handler. button is the
22 button number, starting from 0. state is GLUT_UP or GLUT_DOWN to
23 indicate the button's new state. The other parameters are the mouse
24 coordinates.
25 Mouse wheel motion can be reported as buttons. If you do not request
27 otherwise, a wheel spun forward will act like a button clicking down,
28 immediately followed by clicking up. Spinning the same wheel backward
29 will act like a different button clicking. Mouse wheel pseudo-buttons
30 are added after all real buttons.
31 While the button is held and the mouse is dragged, you receive mouse-
33 motion events (glutMotionFunc()), even if the mouse is dragged out of the
34 window.
35 This callback is bound to the current window .

39 Reporting the wheel as buttons is actually inherited from X. freeglut
40 added code to support this on WIN32. OpenGLUT inherited that support
41 from freeglut.
42 Old GLUT defines the symbols GLUT_LEFT_BUTTON, GLUT_RIGHT_BUTTON, and
44 GLUT_MIDDLE_BUTTON. However, mice can have more than 3 buttons, so
45 these symbols are deprecated.
46 Windows created via glutCreateMenuWindow() always cascade keyboard and
48 mouse events to their parent.
