Member Function Documentation

void glxGraphicsStateGuardian::choose_pixel_format	(	const FrameBufferProperties &	properties,
		X11_Display *	display,
		int	screen,
		bool	need_pbuffer,
		bool	need_pixmap
	)

Selects a visual or fbconfig for all the windows and buffers that use this gsg.

Also creates the GL context and obtains the visual.

void * glxGraphicsStateGuardian::do_get_extension_func	(	const char *	prefix,
		const char *	name
	)		`[protected, virtual]`

Returns the pointer to the GL extension function with the indicated name.

It is the responsibility of the caller to ensure that the required extension is defined in the OpenGL runtime prior to calling this; it is an error to call this for a function that is not defined.

Reimplemented from PosixGraphicsStateGuardian.

void glxGraphicsStateGuardian::get_extra_extensions ( ) [protected, virtual]

This may be redefined by a derived class (e.g.

glx or wgl) to get whatever further extensions strings may be appropriate to that interface, in addition to the GL extension strings return by glGetString().

Definition at line 613 of file glxGraphicsStateGuardian.cxx.

const FrameBufferProperties & glxGraphicsStateGuardian::get_fb_properties ( ) const [inline]

Gets the FrameBufferProperties for all windows and buffers that use this GSG.

void glxGraphicsStateGuardian::get_properties	(	FrameBufferProperties &	properties,
		XVisualInfo *	visual
	)

Gets the FrameBufferProperties to match the indicated visual.
