NAME

       glutCreateMenu - creates a new pop-up menu.

SYNTAX

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

ARGUMENTS

       func	 The  callback	function for the menu that is called when a menu entry from the menu is selected. The value passed to the callback
		 is determined by the value for the selected menu entry.

DESCRIPTION

       glutCreateMenu creates a new pop-up menu and returns a unique small integer identifier. The range of allocated identifiers starts  at  one.
       The menu identifier range is separate from the window identifier range. Implicitly, the current menu is set to the newly created menu. This
       menu identifier can be used when calling glutSetMenu.

       When the menu callback is called because a menu entry is selected for the menu, the current menu will be implicitly set to  the	menu  with
       the selected entry before the callback is made.

EXAMPLE

       Here is a quick example of how to create a GLUT popup menu with two submenus and attach it to the right button of the current window:

	 int submenu1, submenu2;

	 submenu1 = glutCreateMenu(selectMessage);
	 glutAddMenuEntry("abc", 1);
	 glutAddMenuEntry("ABC", 2);
	 submenu2 = glutCreateMenu(selectColor);
	 glutAddMenuEntry("Green", 1);
	 glutAddMenuEntry("Red", 2);
	 glutAddMenuEntry("White", 3);
	 glutCreateMenu(selectFont);
	 glutAddMenuEntry("9 by 15", 0);
	 glutAddMenuEntry("Times Roman 10", 1);
	 glutAddMenuEntry("Times Roman 24", 2);
	 glutAddSubMenu("Messages", submenu1);
	 glutAddSubMenu("Color", submenu2);
	 glutAttachMenu(GLUT_RIGHT_BUTTON);

X IMPLEMENTATION NOTES

       If  available, GLUT for X will take advantage of overlay planes for implementing pop-up menus. The use of overlay planes can eliminate dis-
       play callbacks when pop-up menus are deactivated. The SERVER_OVERLAY_VISUALS convention is used to determine if overlay visuals are  avail-
       able.
