NAME

     glutPopWindow -- Request to raise the current window to the top

LIBRARY

     OpenGLUT - window

SYNOPSIS

     #include <openglut.h>

     void
     glutPopWindow(void);

DESCRIPTION

     Request that the  current window	be brought to the top.

     A window can be in front of or behind other windows, as determined by the z-order from front to back.  Top-level OpenGLUT windows can be
     placed at the front or back of the z-order by means of the glutPopWindow() and glutPushWindow() API functions.

     A z-order also applies to the subwindows of a top-level window.  While the z-order of top-level windows can usually be adjusted by the user,
     subwindow z-order is controlled entirely by the application.

     If this has any effect on your window's visibility, you should receive a glutWindowStatusFunc() callback and a glutDisplayFunc() callback.

CAVEATS

     The z-order of top-level windows is ultimately managed by the windowing system.  Therefore, a push or pop request by an OpenGLUT application
     may not necessarily succeed or take immediate effect.

     Not applicable to offscreen windows.

NAME

     glutCreateWindow -- Create a new top-level window

LIBRARY

     OpenGLUT - window

SYNOPSIS

     #include <openglut.h>

     int
     glutCreateWindow(const char* title);

PARAMETERS

      title	  Title for created window

DESCRIPTION

     This function sends a request for a window to be constructed.  OpenGLUT immediately constructs a data structure to track further events with
     the window, on the theory that eventually the window manager will get back to us with a real window.  This allows us to begin registering
     callbacks immediately.

     In fact, you  must   register a display callback via glutDisplayFunc() before you enter glutMainLoop().

     For onscreen windows, you should not depend upon the window concretely existing or being visibile until you are told that it exists and is
     visible via a registered callback.

     The return value is an  int.    It should be positive for valid windows or 0 if failure occurred for some reason (Though traditional GLUT
     tends to bail out and abort rather than returning errors.)  The integer is your  window id  .  Old GLUT promises that these integers are
     ``small''; we do not reuse old  id  s, but do produce them sequentially.

     You can change the title later via glutSetWindowTitle().
