Member Function Documentation

◆ addConfig()

void Ogre::GLXGLSupport::addConfig ( void )

virtual

GL3PlusSupport::addConfig

Implements Ogre::GL3PlusSupport.

◆ checkExtension()

virtual bool Ogre::GL3PlusSupport::checkExtension ( const String & ext ) const

virtualinherited

Check if an extension is available.

Reimplemented in Ogre::GTKGLSupport.

◆ chooseFBConfig()

GLXFBConfig* Ogre::GLXGLSupport::chooseFBConfig	(	const GLint *	attribList,
		GLint *	nElements
	)

Portable replacement for glXChooseFBConfig.

◆ createNewContext()

::GLXContext Ogre::GLXGLSupport::createNewContext	(	GLXFBConfig	fbConfig,
		GLint	renderType,
		::GLXContext	shareList,
		GLboolean	direct
	)		const

Portable replacement for glXCreateNewContext.

◆ createWindow()

Window* Ogre::GLXGLSupport::createWindow	(	bool	autoCreateWindow,
		GL3PlusRenderSystem *	renderSystem,
		const String &	windowTitle
	)

virtual

Implements Ogre::GL3PlusSupport.

◆ getConfigOptions()

virtual ConfigOptionMap& Ogre::GL3PlusSupport::getConfigOptions ( void )

virtualinherited

◆ getDisplayMonitorCount()

virtual unsigned int Ogre::GL3PlusSupport::getDisplayMonitorCount ( ) const

inlinevirtualinherited

Gets the number of display monitors.

See also: Root::getDisplayMonitorCount

Reimplemented in Ogre::Win32GLSupport.

◆ getDisplayName()

String Ogre::GLXGLSupport::getDisplayName ( void )

Get the name of the display and screen used for rendering.

Ogre normally opens its own connection to the X server and renders onto the screen where the user logged in

However, if Ogre is passed a current GL context when the first RenderTarget is created, then it will connect to the X server using the same connection as that GL context and direct all subsequent rendering to the screen targeted by that GL context.

Returns: Display name.

◆ getFBConfigAttrib()

GLint Ogre::GLXGLSupport::getFBConfigAttrib	(	GLXFBConfig	fbConfig,
		GLint	attribute,
		GLint *	value
	)

Portable replacement for glXGetFBConfigAttrib.

◆ getFBConfigFromContext()

GLXFBConfig Ogre::GLXGLSupport::getFBConfigFromContext ( ::GLXContext context )

Get the GLXFBConfig used to create a ::GLXContext.

Parameters

drawable GLXContext

Returns: GLXFBConfig used to create the context

◆ getFBConfigFromDrawable()

GLXFBConfig Ogre::GLXGLSupport::getFBConfigFromDrawable	(	GLXDrawable	drawable,
		unsigned int *	width,
		unsigned int *	height
	)

Get the GLXFBConfig used to create a GLXDrawable.

Caveat: GLX version 1.3 is needed when the drawable is a GLXPixmap

Parameters

drawable	GLXDrawable
width	Receiver for the drawable width
height	Receiver for the drawable height

Returns: GLXFBConfig used to create the drawable

◆ getFBConfigFromVisualID()

GLXFBConfig Ogre::GLXGLSupport::getFBConfigFromVisualID ( VisualID visualid )

Gets a GLXFBConfig compatible with a VisualID.

Some platforms fail to implement glXGetFBconfigFromVisualSGIX as part of the GLX_SGIX_fbconfig extension, but this portable alternative suffices for the creation of compatible contexts.

Parameters

visualid VisualID

Returns: FBConfig for VisualID

◆ getGLDisplay()

Display* Ogre::GLXGLSupport::getGLDisplay ( void )

Get the Display connection used for rendering.

This function establishes the initial connection when necessary.

Returns: Display connection

◆ getGLVendor()

const String& Ogre::GL3PlusSupport::getGLVendor ( void ) const

inlineinherited

Get vendor information.

◆ getGLVersion()

const DriverVersion& Ogre::GL3PlusSupport::getGLVersion ( void ) const

inlineinherited

Get version information.

◆ getProcAddress()

void* Ogre::GLXGLSupport::getProcAddress ( const char * procname ) const

virtual

GL3PlusSupport::getProcAddress

Implements Ogre::GL3PlusSupport.

◆ getShaderCachePath()

const String& Ogre::GL3PlusSupport::getShaderCachePath ( void ) const

inlineinherited

Get shader cache path.

◆ getShaderLibraryPath()

const String& Ogre::GL3PlusSupport::getShaderLibraryPath ( void ) const

inlineinherited

Get shader library path.

◆ getVisualFromFBConfig()

XVisualInfo* Ogre::GLXGLSupport::getVisualFromFBConfig ( GLXFBConfig fbConfig )

Portable replacement for glXGetVisualFromFBConfig.

◆ getXDisplay()

Display* Ogre::GLXGLSupport::getXDisplay ( void )

Get the Display connection used for window management & events.

Returns: Display connection

◆ hasMinGLVersion()

bool Ogre::GL3PlusSupport::hasMinGLVersion	(	int	major,
		int	minor
	)		const

inherited

Check if GL Version is supported.

◆ initialiseExtensions()

void Ogre::GLXGLSupport::initialiseExtensions ( )

virtual

GL3PlusSupport::initialiseExtensions

Reimplemented from Ogre::GL3PlusSupport.

◆ loadIcon()

bool Ogre::GLXGLSupport::loadIcon	(	const String &	name,
		Pixmap *	pix,
		Pixmap *	mask
	)

Loads an icon from an Ogre resource into the X Server.

This currently only works for 24 and 32 bit displays. The image must be findable by the Ogre resource system, and of format PF_A8R8G8B8.

Parameters

display	X display
name	Name of image to load
pix	Receiver for the output pixmap
mask	Receiver for the output mask (alpha bitmap)

Returns: true on success

◆ newWindow()

Window* Ogre::GLXGLSupport::newWindow	(	const String &	name,
		uint32	width,
		uint32	height,
		bool	fullScreen,
		const NameValuePairList *	miscParams = `0`
	)

virtual

Implements Ogre::GL3PlusSupport.

◆ selectFBConfig()

GLXFBConfig Ogre::GLXGLSupport::selectFBConfig	(	const int *	minAttribs,
		const int *	maxAttribs
	)

Select an FBConfig given a list of required and a list of desired properties.

Parameters

minAttribs	FBConfig attributes that must be provided with minimum values
maxAttribs	FBConfig attributes that are desirable with maximum values

Returns: GLXFBConfig with attributes or 0 when unsupported.

◆ setConfigOption()

void Ogre::GLXGLSupport::setConfigOption	(	const String &	name,
		const String &	value
	)

virtual

GL3PlusSupport::setConfigOption

Reimplemented from Ogre::GL3PlusSupport.

virtual

GL3PlusSupport::start

Implements Ogre::GL3PlusSupport.

◆ stop()

void Ogre::GLXGLSupport::stop ( )

virtual

GL3PlusSupport::stop

Implements Ogre::GL3PlusSupport.

◆ switchMode() [1/2]

void Ogre::GLXGLSupport::switchMode	(	uint32	width,
		uint32	height,
		short	frequency
	)

Switch video modes.

Parameters

width	Receiver for requested and final width
height	Receiver for requested and final drawable height
height	Receiver for requested and final drawable frequency

String Ogre::GLXGLSupport::validateConfig ( void )

virtual

GL3PlusSupport::validateConfig

Implements Ogre::GL3PlusSupport.
