glutGameModeGet -- Return the value of a game mode parameter LIBRARY
OpenGLUT - gamemode SYNOPSIS
#include <openglut.h> int glutGameModeGet(GLenum pname); PARAMETERS
pname The parameter value to be returned DESCRIPTION
pname is one of: - GLUT_GAME_MODE_ACTIVE Return non-zero if we are presently in gamemode. - GLUT_GAME_MODE_POSSIBLE Return whether the requested gamemode settings are viable. (May also actually change the mode?) Does not necessarily tell you whether entering gamemode will have any effect. - GLUT_GAME_MODE_WIDTH Return the game mode width. (in pixels) - GLUT_GAME_MODE_HEIGHT Return the game mode height. (in pixels) - GLUT_GAME_MODE_PIXEL_DEPTH Return the game mode pixel depth. (in bits) - GLUT_GAME_MODE_REFRESH_RATE Return the game mode vertical refresh frequency. (in Hz) - GLUT_GAME_MODE_DISPLAY_CHANGED Return non-zero if we are presently in gamemode. (Same as GLUT_GAME_MODE_ACTIVE.) If pname is unknown, a warning is printed and a value of -1 is returned. TODO

glutDeviceGet -- Allows you to get some device state/option variables. LIBRARY
OpenGLUT - inputstate SYNOPSIS
#include <openglut.h> int glutDeviceGet(GLenum eWhat); PARAMETERS
eWhat Enumerated parameter ID. DESCRIPTION
Retrieves some system-specific information about attached devices. Supported device queries are: - GLUT_HAS_JOYSTICK Return non-zero if there is a joystick. - GLUT_HAS_KEYBOARD Return non-zero if there is a keyboard. - GLUT_HAS_MOUSE Return non-zero if there is a mouse. - GLUT_HAS_SPACEBALL Return non-zero if there is a spaceball. - GLUT_JOYSTICK_AXES Return the number of axes for the joystick. - GLUT_JOYSTICK_POLL_RATE Return the rate (in GLUT timer ticks?) at which the joystick is polled. - GLUT_NUM_MOUSE_BUTTONS Return the number of buttons that the user's mouse has. - GLUT_OWNS_JOYSTICK Return non-zero if OpenGLUT believes that it has successfully acquired access to the joystick. - GLUT_DEVICE_IGNORE_KEY_REPEAT Return non-zero if the current window is set to disable key repeating. - GLUT_DEVICE_KEY_REPEAT Described as returning the key repeat rate in one place, but actually returns a key repeat mode. - GLUT_HAS_DIAL_AND_BUTTON_BOX Return non-zero if a dials-and-buttons box is present. - GLUT_HAS_TABLET Return non-zero if a tablet is present. - GLUT_NUM_BUTTON_BOX_BUTTONS Return the number of buttons on a dials-and-buttons box, if any. - GLUT_NUM_DIALS Return the number of dials on a dials-and-buttons box, if any. - GLUT_NUM_SPACEBALL_BUTTONS Return the number of buttons on a spaceball, if any. - GLUT_NUM_TABLET_BUTTONS Return the number of buttons on a tablet, if any. TODO
Only supports querying for one joystick. Consider moving to a table-based approach rather than a switch(), letting us move to modular functions. BUGS
Keyboards are optional, but OpenGLUT doesn't detect their absence. Mice are optional, but OpenGLUT is only able to check for them under WIN32. Mice can have a varying number of buttons, but OpenGLUT assumes exactly 3 on UNIX_X11. Not all joystick queries are implemented yet. GLUT_DEVICE_KEY_REPEAT returns the key repeat mode, but the comment says it returns the rate . Some things, like joystick poll rates, seem to have insufficient context. Which joystick? Which window? Maybe we assume the current window and the current joystick (or the first one)? GLUT_DEVICE_KEY_REPEAT should probably return ogState.KeyRepeat. SEE ALSO
