NAME

X11::GLX::FBConfig - Framebuffer configuration

VERSION

version 0.06

DESCRIPTION

This is a view of the opaque GLXFBConfig struct used by OpenGL to describe a framebuffer format. This is similar to an X11 Visual, but has more attributes specific to OpenGL.

ATTRIBUTES

display

Returns reference to the X11::Xlib instance this object was created from. (this object wraps a pointer whose scope seems to be the life of the X11 connection) Note that this FBConfig holds a strong reference to the connection, so the connection won't go out of scope as long as you hold onto this object.

visual_info

Returns an XVisualInfo for the FBConfig.

xid

Returns the X11 ID for this FBConfig.

C API Attributes

The following attributes have perl-ified names of the C API constants described in the Khronos documentation.

buffer_size

level

doublebuffer

stereo

aux_buffers

red_size

green_size

blue_size

alpha_size

depth_size

stencil_size

accum_red_size

accum_green_size

accum_blue_size

accum_alpha_size

render_type

drawable_type

x_renderable

visual_id

x_visual_type

config_caveat

transparent_type

transparent_index_value

transparent_red_value

transparent_green_value

transparent_blue_value

max_pbuffer_width

max_pbuffer_height

max_pbuffer_pixels

METHODS

get_attr

use X11::GLX ':constants';
my $val= $fbconfig->get_attr($GLX_CONSTANT);

Retrieve a GLX constant. Dies if $GLX_CONSTANT is not a valid attriute (according to GLX return value). Also dies if this FBConfig doesn't have an associated display or if the display has been closed.
