NAME

     glutCreateMenu -- Create a new menu.

LIBRARY

     OpenGLUT - menus

SYNOPSIS

     #include <openglut.h>

     int
     glutCreateMenu(void( *callback )( int value ));

PARAMETERS

      callback	   Client hook for the new menu.

DESCRIPTION

     Create a menu with a callback bound to  callback,	and return the menu's integer id.

     When the user makes a selection from this menu,  callback	is invoked with the parameter  value,  which comes from the (  label,	value)
     pair that is defined with glutAddMenuEntry().

NAME

       glutMenuStatusFunc - sets the global menu status callback.

SYNTAX

       void glutMenuStatusFunc(void (*func)(int status, int x, int y));
       void glutMenuStateFunc(void (*func)(int status));

ARGUMENTS

       func	 The new menu status (or state) callback function.

DESCRIPTION

       glutMenuStatusFunc  sets  the  global menu status callback so a GLUT program can determine when a menu is in use or not. When a menu status
       callback is registered, it will be called with the value GLUT_MENU_IN_USE for its value parameter when pop-up menus are in use by the user;
       and  the callback will be called with the value GLUT_MENU_NOT_IN_USE for its status parameter when pop-up menus are no longer in use. The x
       and y parameters indicate the location in window coordinates of the button press that caused the menu to go into use, or the location where
       the  menu  was  released  (may  be outside the window). The func parameter names the callback function. Other callbacks continue to operate
       (except mouse motion callbacks) when pop-up menus are in use so the menu status callback allows a program to  suspend  animation  or  other
       tasks  when menus are in use. The cascading and unmapping of sub-menus from an initial pop-up menu does not generate menu status callbacks.
       There is a single menu status callback for GLUT.

       When the menu status callback is called, the current menu will be set  to  the  initial	pop-up	menu  in  both	the  GLUT_MENU_IN_USE  and
       GLUT_MENU_NOT_IN_USE  cases.  The  current  window  will  be set to the window from which the initial menu was popped up from, also in both
       cases.

       Passing NULL to glutMenuStatusFunc disables the generation of the menu status callback.

       glutMenuStateFunc is a deprecated version of the glutMenuStatusFunc routine. The only difference is  glutMenuStateFunc  callback  prototype
       does not deliver the two additional x and y coordinates.
