Detailed Description

A system window for OpenGL rendering.

The GLWindow implements all generic OpenGL functionality for a SystemWindow. It is subclassed by OS-specific implementations which provide the the glue to the actual window system.

Constructor & Destructor Documentation

eq::GLWindow::GLWindow

(

Window *

parent

)

Construct a new OpenGL window.

Version:

1.0

virtual eq::GLWindow::~GLWindow

(

)

[virtual]

Destruct a new OpenGL window.

Version:

1.0

Member Function Documentation

virtual void eq::GLWindow::bindFrameBuffer

(

)

const [virtual]

Bind the window's FBO, if it uses an FBO drawable.

Version:

1.0

Implements eq::SystemWindow.

virtual void eq::GLWindow::configExitFBO

(

)

[virtual]

Destroy the FBO.

Version:

1.0

Reimplemented from eq::SystemWindow.

virtual bool eq::GLWindow::configInitFBO

(

)

[virtual]

Build and initialize the FBO.

Version:

1.0

Reimplemented from eq::SystemWindow.

virtual void eq::GLWindow::exitGLEW

(

)

[inline, virtual]

De-initialize the GLEW context.

Version:

1.0

Definition at line 71 of file glWindow.h.

virtual const util::FrameBufferObject* eq::GLWindow::getFrameBufferObject

(

)

const [inline, virtual]

Returns:

the FBO of this window, or 0.

Version:

1.0

Reimplemented from eq::SystemWindow.

Definition at line 63 of file glWindow.h.

virtual const GLEWContext* eq::GLWindow::glewGetContext

(

)

const [virtual]

Get the GLEW context for this window.

The glew context is initialized during window initialization, and provides access to OpenGL extensions. This function does not follow the Equalizer naming conventions, since GLEW uses a function of this name to automatically resolve OpenGL function entry points. Therefore, any supported GL function can be called directly from an initialized GLWindow.

Returns:

the extended OpenGL function table for the window's OpenGL context.

Version:

1.0

Reimplemented from eq::SystemWindow.

virtual void eq::GLWindow::initGLEW

(

)

[virtual]

Initialize the GLEW context for this window.

Version:

1.0

bool eq::GLWindow::isCurrent

(

)

const

Returns:

true if this window was last made current in this thread.

Version:

1.3.2

virtual void eq::GLWindow::makeCurrent

(

const bool

cache = true

)

const [virtual]

Bind the FBO and update the current cache.

Version:

1.0

Implements eq::SystemWindow.

Reimplemented in eq::wgl::Window, eq::agl::Window, and eq::glx::Window.

virtual void eq::GLWindow::queryDrawableConfig

(

DrawableConfig &

)

[virtual]

Set up the drawable config by querying the current context.

Version:

1.0

Implements eq::SystemWindow.
