NAME

     glutCreateMenuWindow -- Create a client-controlled menu window.

LIBRARY

     OpenGLUT - experimental

SYNOPSIS

     #include <openglut.h>

     int
     glutCreateMenuWindow(int parentID, int x, int y, int w, int h);

PARAMETERS

      parentID	   Parent window identifier.

      x 	   Horizontal coordinate on the screen.

      y 	   Vertical coordinate on the screen.

      w 	   Width of the new window.

      h 	   Height of the new window.

DESCRIPTION

     This is a highly experimental function.  It creates a menu-like window, of requested dimensions, and at a position relative to your current
     window.

     The documentation for this function is currently the OpenGLUT Menu Window proposal.  Variance from that proposal may generally be explained
     by the fact that this feature is highly experimental.  It may also be explained by the fact that the implementation may simply be incomplete.

CAVEATS

     Did you notice that this feature is highly experimental?

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().
