Class pyglet.gl.gl_info.GLInfo

Information interface for a single GL context.

A default instance is created automatically when the first OpenGL context is created. You can use the module functions as a convenience for this default instance's methods.

If you are using more than one context, you must call set_active_context when the context is active for this GLInfo instance.

Methods

	set_active_context(self) Store information for the currently active context.
	remove_active_context(self)
bool	have_extension(self, extension) Determine if an OpenGL extension is available.
list of str	get_extensions(self) Get a list of available OpenGL extensions.
str	get_version(self) Get the current OpenGL version.
bool	have_version(self, major, minor=0, release=0) Determine if a version of OpenGL is supported.
str	get_renderer(self) Determine the renderer string of the OpenGL context.
str	get_vendor(self) Determine the vendor string of the OpenGL context.

Class Variables

	have_context = `False`
	version = `'0.0.0'`
	vendor = `''`
	renderer = `''`
	extensions = `set([])`

Method Details

set_active_context

set_active_context(self)

Store information for the currently active context.

This method is called automatically for the default context.

have_extension

have_extension(self, extension)

Determine if an OpenGL extension is available.

Parameters:

extension : str: The name of the extension to test for, including its GL_ prefix.

Returns:

bool: True if the extension is provided by the driver.

get_extensions

get_extensions(self)

Get a list of available OpenGL extensions.

Returns:: list of str: a list of the available extensions.

get_version

get_version(self)

Get the current OpenGL version.

Returns:: str: the OpenGL version

have_version

have_version(self, major, minor=0, release=0)

Determine if a version of OpenGL is supported.

Parameters:

major : int: The major revision number (typically 1 or 2).
minor : int: The minor revision number.
release : int: The release number.

Returns:

bool: True if the requested or a later version is supported.
