(freeglut only) Contains the thickness of the sizing border around the perimeter of a window that can be resized, in pixels.

(freeglut only) Contains the height of the header/caption area of a window in pixels.

(freeglut on X11 only) Controls if all but the last motion event should be discarded.

Contains True when the current layer of the current window is in RGBA mode, False means color index mode.

Bit depth of a buffer

Contains the number of red, green, blue, and alpha bits in the color buffer of the current window's current layer (0 in color index mode).

Contains the total number of bits in the color buffer of the /current window's/ current layer. For an RGBA layer, this is the sum of the red, green, blue, and alpha bits. For an color index layer, this is the number of bits of the color indexes.

Contains True when the current layer of the current window is double buffered, False otherwise.

Contains True when the current layer of the current window is stereo, False otherwise.

Contains the number of red, green, blue, and alpha bits in the accumulation buffer of the current window's current layer (0 in color index mode).

Contains the number of bits in the depth buffer of the current window's current layer.

Contains the number of bits in the stencil buffer of the /current window's/ current layer.

Number of samples for multisampling

Contains the number of samples for multisampling for the current window.

Contains the window system dependent format ID for the current layer of the current window. On X11 GLUT implementations, this is the X visual ID. On Win32 GLUT implementations, this is the Win32 Pixel Format Descriptor number. This value is returned for debugging, benchmarking, and testing ease.

(freeglut only) Contains True if the current window is in full screen mode, False otherwise.

(freeglut only) Controls if vectors representing the normals should be drawn, too, when objects are drawn.

(freeglut only) If vertexAttribCoord3 and vertexAttribNormal both contain Nothing, the fixed function pipeline is used to draw objects. Otherwise VBOs are used and the coordinates are passed via Just this attribute location (for a vec3).

(freeglut only) If vertexAttribCoord3 and vertexAttribNormal both contain Nothing, the fixed function pipeline is used to draw objects. Otherwise VBOs are used and the normals are passed via Just this attribute location (for a vec3).

(freeglut only) If VBOs are used to draw objects (controlled via vertexAttribCoord3 and vertexAttribNormal), the texture coordinates are passed via Just this attribute location (for a vec2).

Contains True if the given plane of the current window has been damaged (by window system activity) since the last display callback was triggered. Calling postRedisplay or postOverlayRedisplay will not set this True.

Contains the number of milliseconds since initialize was called.

The size of the screen in pixels.

The size of the screen in millimeters.

Contains True if a keyboard is present, False otherwise.

Number of buttons of an input device

Contains Just the number of buttons of an attached mouse or Nothing if there is none.

Contains Just the number of buttons of the attached Spaceball or Nothing if there is none.

Number of dials of a dial and button box

Contains Just the number of dials and buttons of an attached dial & button box or Nothing if there is none.

Contains Just the number of buttons of an attached tablet or Nothing if there is none.

Number of axes of a joystick

The a rate at which a joystick is polled (in milliseconds)

Contains Just the number of buttons of an attached joystick, the number of joystick axes, and the rate at which the joystick is polled. Contains Nothing if there is no joystick attached.

(freeglut only) Contains a list of the number of auxiliary buffers supported, in increasing order.

(freeglut only) Contains a list of the number of samples per pixel supported for multisampling, in increasing order.

Contains version of GLUT in the form of flavour major.minor.patchlevel, where flavour is one of GLUT, freeglut or OpenGLUT.

(freeglut only) Contains True if GLUT has been initialized with initialize or getArgsAndInitialize has and not yet been de-initialized with exit. Contains False otherwise.
