glutGetModifiers(3GLUT) 					       GLUT						   glutGetModifiers(3GLUT)

NAME

       glutGetModifiers - returns the modifier key state when certain callbacks were generated.

SYNTAX

       #include <GLUT/glut.h>

       int glutGetModifiers(void);

DESCRIPTION

       glutGetModifiers  returns the modifier key state at the time the input event for a keyboard, special, or mouse callback is generated.  This
       routine may only be called while a keyboard, special, or mouse callback is being handled. The window system is permitted to intercept  win-
       dow  system  defined  modifier  key  strokes or mouse buttons, in which case, no GLUT callback will be generated. This interception will be
       independent of use of glutGetModifiers.

       The bitmask components of the returned integer value are:

       GLUT_ACTIVE_SHIFT
	       Set if the Shift modifier or Caps Lock is active.

       GLUT_ACTIVE_CTRL
	       Set if the Ctrl modifier is active.

       GLUT_ACTIVE_ALT
	       Set if the Alt modifier is active.

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.
