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

virtual bool eq::GLWindow::configInitFBO ( )

virtual

Build and initialize the FBO.

Version: 1.0

virtual void eq::GLWindow::exitGLEW ( )

inlinevirtual

De-initialize the GLEW context.

Version: 1.0

Definition at line 77 of file glWindow.h.

virtual void eq::GLWindow::finish ( )

virtual

Finish execution of all commands.

Version: 1.5.2

Implements eq::SystemWindow.

virtual void eq::GLWindow::flush ( )

virtual

Flush all command buffers.

Version: 1.5.2

Implements eq::SystemWindow.

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

inlinevirtual

Returns: the FBO of this window, or 0.

Version: 1.0

Reimplemented from eq::SystemWindow.

Definition at line 69 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.
