glib Constants the built-in constants of the glib module The IO Condition constants are a set of bit-flags that specify a condition to watch for on an event source. glib.IO_IN There is data to read glib.IO_OUT Data can be written (without blocking). glib.IO_PRI There is urgent data to read. glib.IO_ERR Error condition. glib.IO_HUP Hung up (the connection has been broken, usually for pipes and sockets). glib.IO_NVAL Invalid request. The file descriptor is not open. The Priority constants specify glib.PRIORITY_HIGH Use this for high priority event sources. glib.PRIORITY_DEFAULT Use this for default priority event sources. This priority is used when adding timeout functions with the glib.timeout_add() function. This priority is also used for events from the X server. glib.PRIORITY_HIGH_IDLE Use this for high priority idle functions. For example, glib.PRIORITY_HIGH_IDLE + 10 is used for resizing operations; and, glib.PRIORITY_HIGH_IDLE + 20, for redrawing operations. (This is done to ensure that any pending resizes are processed before any pending redraws, so that widgets are not redrawn twice unnecessarily.) glib.PRIORITY_DEFAULT_IDLE Use this for default priority idle functions. This priority is used when adding idle functions with the glib.idle_add() function. glib.PRIORITY_LOW Use this for very low priority background tasks. The Spawn Flag constants are a set of bit-flags that can be passed to the glib.spawn_async() function. glib.SPAWN_LEAVE_DESCRIPTORS_OPEN the parent's open file descriptors will be inherited by the child; otherwise all descriptors except stdin/stdout/stderr will be closed before calling exec() in the child. glib.SPAWN_DO_NOT_REAP_CHILD the child will not be automatically reaped; you must call waitpid() or handle SIGCHLD yourself, or the child will become a zombie. glib.SPAWN_SEARCH_PATH argv[0] need not be an absolute path, it will be looked for in the user's PATH. glib.SPAWN_STDOUT_TO_DEV_NULL the child's standard output will be discarded, instead of going to the same location as the parent's standard output. glib.SPAWN_STDERR_TO_DEV_NULL the child's standard error will be discarded. glib.SPAWN_CHILD_INHERITS_STDIN the child will inherit the parent's standard input (by default, the child's standard input is attached to /dev/null). glib.SPAWN_FILE_AND_ARGV_ZERO the first element of argv is the file to execute, while the remaining elements are the actual argument vector to pass to the file. Normally glib.spawn_async() uses argv[0] as the file to execute, and passes all of argv to the child. The Version constants specify the version of Glib used by PyGObject as a 3-tuple containing the major, minor and patch release numbers. glib.glib_version A 3-tuple containing (major, minor, patch) release numbers of glib. glib.pyglib_version A 3-tuple containing (major, minor, patch) release numbers of the python bindings.
