Detailed Description

The interface definition for system-specific windowing code.

The system window abstracts all window system specific code and facilitates porting to new windowing systems. Each eq::Window uses one eq::SystemWindow, which is created and initialized in Window::configInitSystemWindow.

Constructor & Destructor Documentation

eq::SystemWindow::SystemWindow

(

Window *

parent

)

Create a new SystemWindow for the given eq::Window.

Version:

1.0

virtual eq::SystemWindow::~SystemWindow

(

)

[virtual]

Destroy the SystemWindow.

Version:

1.0

---

Member Function Documentation

virtual void eq::SystemWindow::bindFrameBuffer

(

)

const [pure virtual]

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

Version:

1.0

Implemented in eq::GLWindow.

virtual void eq::SystemWindow::configExit

(

)

[pure virtual]

De-initialize this system window.

This function might be called on partially or uninitialized system windows, and the implemenation has therefore be tolerant enough to handle this case.

Version:

1.0

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

void eq::SystemWindow::configExitFBO

(

)

Destroy FBO.

Version:

1.0

Reimplemented in eq::GLWindow.

virtual bool eq::SystemWindow::configInit

(

)

[pure virtual]

Initialize this system window.

This method should take into account all attributes of the parent Window.

Returns:

true if the window was correctly initialized, false on any error.

Version:

1.0

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

bool eq::SystemWindow::configInitFBO

(

)

Build and initialize the FBO.

Version:

1.0

Reimplemented in eq::GLWindow.

Config* eq::SystemWindow::getConfig

(

)

Returns:

the parent config.

Version:

1.0

const Config* eq::SystemWindow::getConfig

(

)

const

Returns:

the parent config.

Version:

1.0

co::Error eq::SystemWindow::getError

(

)

const

Returns:

the error from the last failed operation.

Version:

1.0

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

(

)

const [inline, virtual]

Returns:

the FBO of this window, or 0.

Version:

1.0

Reimplemented in eq::GLWindow.

Definition at line 107 of file systemWindow.h.

int32_t eq::SystemWindow::getIAttribute

(

const Window::IAttribute

attr

)

const

Returns:

an integer attribute of the parent window.

Version:

1.0

Node* eq::SystemWindow::getNode

(

)

Returns:

the parent node.

Version:

1.0

const Node* eq::SystemWindow::getNode

(

)

const

Returns:

the parent node.

Version:

1.0

Pipe* eq::SystemWindow::getPipe

(

)

Returns:

the parent pipe.

Version:

1.0

const Pipe* eq::SystemWindow::getPipe

(

)

const

Returns:

the parent pipe.

Version:

1.0

Window* eq::SystemWindow::getWindow

(

)

[inline]

Returns:

the parent window.

Version:

1.0

Definition at line 114 of file systemWindow.h.

const Window* eq::SystemWindow::getWindow

(

)

const [inline]

Returns:

the parent window.

Version:

1.0

Definition at line 117 of file systemWindow.h.

virtual const GLEWContext* eq::SystemWindow::glewGetContext

(

)

const [inline, 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 SystemWindow.

Returns:

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

Version:

1.0

Reimplemented in eq::GLWindow.

Definition at line 161 of file systemWindow.h.

virtual void eq::SystemWindow::joinNVSwapBarrier	(	const uint32_t	group,
		const uint32_t	barrier
	)		[pure virtual]

Join a NV_swap_group.

See WGL or GLX implementation and OpenGL extension for details on how to implement this function.

Parameters:

group	the swap group name.
barrier	the swap barrier name.

Version:

1.0

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

virtual void eq::SystemWindow::makeCurrent

(

const bool

cache = true

)

const [pure virtual]

Make the system window rendering context and drawable current.

This function invalidates the pipe's make current cache. If this function is not called, Pipe::setCurrent() has to be called appropriately.

Version:

1.0

Implemented in eq::wgl::Window, eq::agl::Window, eq::glx::Window, and eq::GLWindow.

virtual bool eq::SystemWindow::processEvent

(

const Event &

event

)

[virtual]

Process an event.

Version:

1.0

virtual void eq::SystemWindow::queryDrawableConfig

(

DrawableConfig &

dc

)

[pure virtual]

Set up the given drawable based on the current context.

Version:

1.0

Implemented in eq::GLWindow.

void eq::SystemWindow::setError

(

const int32_t

error

)

Set an error code why the last operation failed.

The error will be set on the parent window.

Parameters:

error

the error message.

Version:

1.0

virtual void eq::SystemWindow::swapBuffers

(

)

[pure virtual]

Swap the front and back buffer.

Version:

1.0

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