  NativeWindow Specification Overview

  
   
NativeWindow Protocol Specification Overview
   
Preface
  This specification, an optional set of packages, describing a protocol for a 
  native windowing interface binding to Java(TM).

  Currently specified native windowing systems are:
  
     EGL/OpenKODE Windowing System
     X11 Windowing System
     Microsoft Windows
     Apple MacOSX
     Java's AWT
  
  

  However, any other native windowing system may be added to the implementation,
  using a generic string identifier and an optional specialisation of:
  
    {@link javax.media.nativewindow.AbstractGraphicsDevice AbstractGraphicsDevice},
        Shall return the new string identifier with {@link javax.media.nativewindow.AbstractGraphicsDevice#getType() getType()}
    {@link javax.media.nativewindow.AbstractGraphicsScreen AbstractGraphicsScreen}
    {@link javax.media.nativewindow.AbstractGraphicsConfiguration AbstractGraphicsConfiguration}
  
  The implementor has to provide the following:
  
     The specialisation of the abstract class {@link javax.media.nativewindow.NativeWindowFactory NativeWindowFactory}
         shall be registered with {@link javax.media.nativewindow.NativeWindowFactory#registerFactory NativeWindowFactory.registerFactory(..)}.

     The specialisation of the abstract class {@link javax.media.nativewindow.GraphicsConfigurationFactory GraphicsConfigurationFactory}
         shall be registered with {@link javax.media.nativewindow.GraphicsConfigurationFactory#registerFactory GraphicsConfigurationFactory.registerFactory(..)}.
  
  This protocol does not describe how to create native windows, but how to bind a native surface to an implementation of 
  and window to an implementation of {@link javax.media.nativewindow.NativeSurface NativeSurface}.
  {@link javax.media.nativewindow.NativeWindow NativeWindow} specializes the NativeSurface.
  However, an implementation of this protocol (e.g. {@link com.jogamp.newt}) may support the creation.
   
Dependencies
  This binding has dependencies to the following:
  
     Either of the following Java implementations:
    
         Java SE 1.6 or later 
         A mobile JavaVM with language 1.6 support, ie:
            
                 Android API Level 9 (Version 2.3) 
                 JamVM 
            
            with
            
                  Java 1.4 java.nio implementation 
            
    
  
  


Package Structure
  The packages defined by this specification include:

    The javax.media.nativewindow package
    This package contains Java bindings for a native windowing system.
    Subsequent packages contain marker type classes, containing native characteristics of the windowing system.
    
        The javax.media.nativewindow.awt package
        This sub package contains classes to cover the native characteristics of the AWT windowing system.

        The javax.media.nativewindow.x11 package
        This sub package contains classes to cover the native characteristics of the X11 windowing system.

        The javax.media.nativewindow.windows package
        This sub package contains classes to cover the native characteristics of the Windows windowing system.

        The javax.media.nativewindow.macosx package
        This sub package contains classes to cover the native characteristics of the MacOSX windowing system.

        The javax.media.nativewindow.egl package
        This sub package contains classes to cover the native characteristics of the EGL/OpenKODE windowing system.
  


Factory Model
Running on a platform with a supported windowing system, the factory model shall be used
to instantiate a native window, see {@link javax.media.nativewindow.NativeWindowFactory NativeWindowFactory}.
