NAME

     glutWarpPointer -- Moves the mouse pointer to given window coordinates.

LIBRARY

     OpenGLUT - window

SYNOPSIS

     #include <openglut.h>

     void
     glutWarpPointer(int x, int y);

PARAMETERS

      x 	Window X coord for mouse.

      y 	Window Y coord for mouse.

DESCRIPTION

     glutWarpPointer() moves the mouse pointer to window-relative coordinates given by	x  and	y.

CAVEATS

      x  and  y  are relative to current window.

     Not applicable for  GLUT_OFFSCREEN  windows.

     Warping means moving, just as if the user had manually moved the mouse.  This can generate mouse-motion callbacks. If your callback then
     moves the pointer again, you may end up in an endless loop.  There is some discussion about changing this, but at present this is just a
     caveat for you, the user, to be aware of.

NAME

       glutMouseFunc - sets the mouse callback for the current window.

SYNTAX

       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.
