public Class GLXARBCreateContext

extends Object
Class Inheritance
Imports
javax.annotation.*, java.nio.*, org.lwjgl.system.*
Native bindings to the GLX_ARB_create_context extension.

With the advent of new versions of OpenGL which deprecate features and/or break backward compatibility with older versions, there is a need and desire to indicate at context creation which interface will be used. These extensions add a new context creation routine with attributes specifying the GL version and context properties requested for the context, and additionally add an attribute specifying the GL profile requested for a context of OpenGL 3.2 or later. It also allows making an OpenGL 3.0 or later context current without providing a default framebuffer.

Requires GLX 1.4.

share_context, boolean
direct rendering is requested if direct is True, and indirect rendering if direct is False. If direct is True, the implementation may nonetheless create an indirect rendering context if any of the following conditions hold:
  • The implementation does not support direct rendering.
  • display is not a local X server.
  • Implementation-dependent limits on the number of direct rendering contexts that can be supported simultaneously are exceeded.

Use IsDirect to determine whether or not a request for a direct rendering context succeeded.

Method Detail

glXCreateContextAttribsARBback to summary
public static long glXCreateContextAttribsARB(long display, long config, long share_context, boolean direct, IntBuffer attrib_list)

Creates an OpenGL rendering context.

If glXCreateContextAttribsARB succeeds, it initializes the context to the initial state defined by the OpenGL specification, and returns a handle to it. This handle can be used to render to any GLX surface (window, pixmap, or pbuffer) compatible with config, subject to constraints imposed by the OpenGL API version of the context.

If share_context is not NULL, then all shareable data (excluding OpenGL texture objects named 0) will be shared by share_context, all other contexts share_context already shares with, and the newly created context. An arbitrary number of GLXContexts can share data in this fashion. The server context state for all sharing contexts must exist in a single address space.

Parameters
display:long

the connection to the X server

config:long

the GLXFBConfig

share_context:long

if not NULL, then all shareable data (excluding OpenGL texture objects named 0) will be shared by share_context, all other contexts share_context already shares with, and the newly created context. An arbitrary number of GLXContexts can share data in this fashion. The server context state for all sharing contexts must exist in a single address space.

direct:boolean

direct rendering is requested if direct is True, and indirect rendering if direct is False. If direct is True, the implementation may nonetheless create an indirect rendering context if any of the following conditions hold:

  • The implementation does not support direct rendering.
  • display is not a local X server.
  • Implementation-dependent limits on the number of direct rendering contexts that can be supported simultaneously are exceeded.

Use IsDirect to determine whether or not a request for a direct rendering context succeeded.

attrib_list:IntBuffer

an optional list of attributes for the context, terminated with None
