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_API eq::GLWindow::GLWindow	(	NotifierInterface &	parent,
		const WindowSettings &	settings
	)

Construct a new OpenGL window.

Version: 1.7.2

virtual EQ_API eq::GLWindow::~GLWindow ( )

virtual

Destruct a new OpenGL window.

Version: 1.0

Member Function Documentation

EQ_API void eq::GLWindow::bindDrawFrameBuffer ( ) const

overridevirtual

Bind the window's draw FBO, used for multisampling.

Version: 1.9

Implements eq::SystemWindow.

EQ_API void eq::GLWindow::bindFrameBuffer ( ) const

overridevirtual

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

Version: 1.0

Implements eq::SystemWindow.

virtual EQ_API void eq::GLWindow::configExitFBO ( )

virtual

Destroy the FBO.

Version: 1.0

virtual EQ_API bool eq::GLWindow::configInitFBO ( )

virtual

Build and initialize the FBO.

Version: 1.0

virtual EQ_API void eq::GLWindow::exitGLEW ( )

virtual

De-initialize the GLEW context.

Version: 1.0

EQ_API void eq::GLWindow::finish ( )

overridevirtual

Finish execution of all commands.

Version: 1.5.2

Implements eq::SystemWindow.

EQ_API void eq::GLWindow::flush ( )

overridevirtual

Flush all command buffers.

Version: 1.5.2

Implements eq::SystemWindow.

EQ_API const util::FrameBufferObject* eq::GLWindow::getFrameBufferObject ( ) const

overridevirtual

Returns: the FBO of this window, or 0.

Version: 1.0

Reimplemented from eq::SystemWindow.

EQ_API util::FrameBufferObject* eq::GLWindow::getFrameBufferObject ( )

overridevirtual

Returns: the FBO of this window, or 0.

Version: 1.9

Reimplemented from eq::SystemWindow.

EQ_API const GLEWContext* eq::GLWindow::glewGetContext ( ) const

overridevirtual

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.
