NAME

glutCreateWindow - Create a new top-level window  

LIBRARY

OpenGLUT - window  

SYNOPSIS

In openglut.h Ft int Fn glutCreateWindow const char* title  

PARAMETERS

Bf Em
 title Ef
      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 Bf Em
 must Ef
  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 Bf Sy
 int. Ef
  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 Bf Li
 window id Ef
 .  Old GLUT promises that these integers are ``small''; we do not reuse old Bf Li
 id Ef
 s, but do produce them sequentially.

You can change the title later via glutSetWindowTitle().
