NAME

glutGet - retrieves simple GLUT state represented by integers.

SYNTAX

int glutGet(GLenum state);

ARGUMENTS

state: Name of state to retrieve.

GLUT_WINDOW_X: X location in pixels (relative to the screen origin) of the current window.

GLUT_WINDOW_Y: Y location in pixels (relative to the screen origin) 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_WINDOW_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 current 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 in the current layer of current window's color buffer. Zero if the current layer of the current window is color index.

GLUT_WINDOW_ALPHA_SIZE: Number of bits of alpha stored in 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_WINDOW_NUM_SAMPLES: Number of samples for multisampling for the current 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_WINDOW_FORMAT_ID: 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.

GLUT_WINDOW_BORDER_WIDTH: Width of the window's border in pixels.

GLUT_WINDOW_BORDER_HEIGHT: Height of non-client area above window in pixels, including both border and caption (if any).

GLUT_ALLOW_NEGATIVE_WINDOW_POSITION: One if negative window positions are enabled, zero otherwise.

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 indicates 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_FULL_SCREEN: One if the window is currently in fullscreen mode, zero otherwise.

GLUT_INIT_STATE: One if GLUT has been initialized through a call to glutInit, zero otherwise.

GLUT_VERSION: Return value will be X*10000+Y*100+Z where X is the major version, Y is the minor version and Z is the patch level. This query is only supported in freeglut (version 2.0.0 or later).

DESCRIPTION

glutGet retrieves simple GLUT state represented by integers. 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.
