glutGet(3GLUT) GLUT glutGet(3GLUT)NAMEglutGet - retrieves simple GLUT state represented by inte
gers.
SYNTAX
int glutGet(GLenum state);
ARGUMENTS
state Name of state to retrieve.
GLUT_WINDOW_X
X location in pixels (relative to the screen ori
gin) of the current window.
GLUT_WINDOW_Y
Y location in pixels (relative to the screen ori
gin) of the current window.
GLUT_WINDOW_WIDTH
Width in pixels of the current window.
GLUT_WINDOW_HEIGHT
Height in pixels of the current window.
GLUT_WINDOW_BUFFER_SIZE
Total number of bits for current layer of current
window's color buffer. For an RGBA window, this is
the sum of GLUT_WINDOW_RED_SIZE, GLUT_WIN
DOW_GREEN_SIZE, GLUT_WINDOW_BLUE_SIZE, and
GLUT_WINDOW_ALPHA_SIZE. For color index windows,
this is the size of the color indexes.
GLUT_WINDOW_STENCIL_SIZE
Number of bits in the current layer of current
window's stencil buffer.
GLUT_WINDOW_DEPTH_SIZE
Number of bits in the current layer of current
window's depth buffer.
GLUT_WINDOW_RED_SIZE
Number of bits of red stored the current layer of
current window's color buffer. Zero if the cur
rent layer of the current window is color index.
GLUT_WINDOW_GREEN_SIZE
Number of bits of green stored the current layer
of current window's color buffer. Zero if the
current layer of the current window is color
index.
GLUT_WINDOW_BLUE_SIZE
Number of bits of blue stored the current layer of
current window's color buffer. Zero if the

glutGet(3GLUT) GLUT glutGet(3GLUT)
current layer of the current window is color
index.
GLUT_WINDOW_ALPHA_SIZE
Number of bits of alpha stored the current layer
of current window's color buffer. Zero if the
current layer of the current window is color
index.
GLUT_WINDOW_ACCUM_RED_SIZE
Number of bits of red stored in the current layer
of current window's accumulation buffer. Zero if
the current layer of the current window is color
index.
GLUT_WINDOW_ACCUM_GREEN_SIZE
Number of bits of green stored in the current
layer of current window's accumulation buffer.
Zero if the current layer of the current window is
color index.
GLUT_WINDOW_ACCUM_BLUE_SIZE
Number of bits of blue stored in the current layer
of current window's accumulation buffer. Zero if
the current layer of the current window is color
index.
GLUT_WINDOW_ACCUM_ALPHA_SIZE
Number of bits of alpha stored in the current
layer of current window's accumulation buffer.
Zero if the current layer of the current window is
color index.
GLUT_WINDOW_DOUBLEBUFFER
One if the current layer of the current window is
double buffered, zero otherwise.
GLUT_WINDOW_RGBA
One if the current layer of the current window is
RGBA mode, zero otherwise (i.e., color index).
GLUT_WINDOW_PARENT
The window number of the current window's parent;
zero if the window is a top-level window.
GLUT_WINDOW_NUM_CHILDREN
The number of subwindows the current window has
(not counting children of children).
GLUT_WINDOW_COLORMAP_SIZE
Size of current layer of current window's color
index colormap; zero for RGBA color model layers.
GLUT 3.7 2
glutGet(3GLUT) GLUT glutGet(3GLUT)
GLUT_WINDOW_NUM_SAMPLES
Number of samples for multisampling for the cur
rent layer of the current window.
GLUT_WINDOW_STEREO
One if the current layer of the current window is
stereo, zero otherwise.
GLUT_WINDOW_CURSOR
Current cursor for the current window.
GLUT_SCREEN_WIDTH
Width of the screen in pixels. Zero indicates the
width is unknown or not available.
GLUT_SCREEN_HEIGHT
Height of the screen in pixels. Zero indicates the
height is unknown or not available.
GLUT_SCREEN_WIDTH_MM
Width of the screen in millimeters. Zero indicates
the width is unknown or not available.
GLUT_SCREEN_HEIGHT_MM
Height of the screen in millimeters. Zero indi
cates the height is unknown or not available.
GLUT_MENU_NUM_ITEMS
Number of menu items in the current menu.
GLUT_DISPLAY_MODE_POSSIBLE
Whether the current display mode is supported or
not.
GLUT_INIT_DISPLAY_MODE
The initial display mode bit mask.
GLUT_INIT_WINDOW_X
The X value of the initial window position.
GLUT_INIT_WINDOW_Y
The Y value of the initial window position.
GLUT_INIT_WINDOW_WIDTH
The width value of the initial window size.
GLUT_INIT_WINDOW_HEIGHT
The height value of the initial window size.
GLUT_ELAPSED_TIME
Number of milliseconds since glutInit called (or
first call to glutGet(GLUT_ELAPSED_TIME)).
GLUT 3.7 3
glutGet(3GLUT) GLUT glutGet(3GLUT)
GLUT_WINDOW_FORMAT_ID
The window system dependent format ID for the cur
rent 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.
DESCRIPTIONglutGet retrieves simple GLUT state represented by inte
gers. The state parameter determines what type of state to
return. Where appropriate, window capability state is
returned for the layer in use. GLUT state names beginning
with GLUT_WINDOW_ return state for the current window.
GLUT state names beginning with GLUT_MENU_ return state
for the current menu. Other GLUT state names return global
state. Requesting state for an invalid GLUT state name
returns negative one.
