glutChangeToSubMenu(3GLUT)					       GLUT						glutChangeToSubMenu(3GLUT)

NAME

       glutChangeToSubMenu - changes the specified menu item in the current menu into a sub-menu trigger.

SYNTAX

       #include <GLUT/glut.h>

       void glutChangeToSubMenu(int entry, char *name, int menu);

ARGUMENTS

       entry	 Index into the menu items of the current menu (1 is the topmost menu item).

       name	 ASCII character string to display in the menu item to cascade the sub-menu from.

       menu	 Identifier of the menu to cascade from this sub-menu menu item.

DESCRIPTION

       glutChangeToSubMenu  changes the specified menu item in the current menu into a sub-menu trigger. The entry parameter determines which menu
       item should be changed, with one being the topmost item. entry must be between 1 and glutGet(GLUT_MENU_NUM_ITEMS) inclusive.  The menu item
       to  change  does  not have to be a sub-menu trigger already.  The string name will be displayed for the newly changed sub-menu trigger. The
       menu identifier names the sub-menu to cascade from the newly added sub-menu trigger.

glutMenuStatusFunc(3GLUT)					       GLUT						 glutMenuStatusFunc(3GLUT)

NAME

       glutMenuStatusFunc - sets the global menu status callback.

SYNTAX

       #include <GLUT/glut.h>

       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.
