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

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

Version: 1.7.2

virtual EQ_API eq::SystemWindow::~SystemWindow ( )

virtual

Destroy the SystemWindow.

Version: 1.0

Member Function Documentation

virtual EQ_API void eq::SystemWindow::bindDrawFrameBuffer ( ) const

pure virtual

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

Version: 1.9

Implemented in eq::GLWindow, eq::qt::ShareContextWindow, and eq::x11::Window.

virtual EQ_API 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, eq::qt::ShareContextWindow, and eq::x11::Window.

virtual EQ_API 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::qt::Window, eq::glx::Window, eq::qt::ShareContextWindow, and eq::x11::Window.

virtual EQ_API 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::qt::Window, eq::glx::Window, eq::qt::ShareContextWindow, and eq::x11::Window.

virtual EQ_API void eq::SystemWindow::finish ( )

pure virtual

Finish execution of all commands.

Version: 1.5.2

Implemented in eq::GLWindow, eq::qt::ShareContextWindow, and eq::x11::Window.

virtual EQ_API void eq::SystemWindow::flush ( )

pure virtual

Flush all command buffers.

Version: 1.5.2

Implemented in eq::GLWindow, eq::qt::ShareContextWindow, and eq::x11::Window.

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

inlinevirtual

Returns: the FBO of this window, or 0.

Version: 1.0

Reimplemented in eq::GLWindow.

Definition at line 112 of file systemWindow.h.

virtual util::FrameBufferObject* eq::SystemWindow::getFrameBufferObject ( )

inlinevirtual

Returns: the FBO of this window, or 0.

Version: 1.0

Reimplemented in eq::GLWindow.

Definition at line 115 of file systemWindow.h.

EQ_API int32_t eq::SystemWindow::getIAttribute ( const WindowSettings::IAttribute attr ) const

Returns: the value of an integer attribute.

Version: 1.7.2

EQ_API const std::string& eq::SystemWindow::getName ( ) const

Returns: the window's name.

Version: 1.7.2

EQ_API const PixelViewport& eq::SystemWindow::getPixelViewport ( ) const

Returns: the window's pixel viewport wrt the parent pipe.

Version: 1.7.2

EQ_API const SystemWindow* eq::SystemWindow::getSharedContextWindow ( ) const

Returns: the window with which this window shares the GL context.

Version: 1.7.2

virtual const GLEWContext* eq::SystemWindow::glewGetContext ( ) const

inlinevirtual

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 138 of file systemWindow.h.

virtual EQ_API 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::glx::Window, eq::qt::Window, eq::qt::ShareContextWindow, and eq::x11::Window.

virtual EQ_API 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::glx::Window, eq::qt::Window, eq::qt::ShareContextWindow, eq::GLWindow, and eq::x11::Window.

virtual EQ_API bool eq::SystemWindow::processEvent ( const Event & event )

virtual

Process an event.

Version: 1.0

Reimplemented in eq::qt::ShareContextWindow.

virtual EQ_API 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, eq::qt::ShareContextWindow, and eq::x11::Window.

EQ_API EventOCommand eq::SystemWindow::sendError ( const uint32_t error )

Send a window error event to the application node.

Parameters

error the error code.

Version: 1.7.1

EQ_API void eq::SystemWindow::setName ( const std::string & name )

Set the window's name.

Version: 1.7.2

EQ_API void eq::SystemWindow::setPixelViewport ( const PixelViewport & pvp )

Set the window's pixel viewport wrt its parent pipe.

Parameters

pvp	the viewport in pixels.

Version: 1.7.2

virtual EQ_API void eq::SystemWindow::swapBuffers ( )

pure virtual

Swap the front and back buffer.

Version: 1.0

Implemented in eq::wgl::Window, eq::glx::Window, eq::qt::Window, eq::qt::ShareContextWindow, and eq::x11::Window.

virtual EQ_API void eq::SystemWindow::updateFrameBuffer ( ) const

pure virtual

Update the window's FBO from the multisampled FBO.

Version: 1.9

Implemented in eq::GLWindow, eq::qt::ShareContextWindow, and eq::x11::Window.
