Constant Summary

ALLOC_AND_FREE = 2

ALLOC_ONLY = 1

ALLOCATOR_LIST = 1

ALLOCATOR_NODE = 3

ALLOCATOR_SLIST = 2

ATOMIC_REF_COUNT_INIT = 1

Evaluates to the initial reference count for gatomicrefcount.

This macro is useful for initializing gatomicrefcount fields inside structures, for instance:

|[ typedef struct { gatomicrefcount ref_count; char *name; char *address; } Person;

static const Person default_person = { .ref_count = G_ATOMIC_REF_COUNT_INIT, .name = "Default name", .address = "Default address", }; ]|

MAJOR_VERSION = 2

The major version number of the GLib library.

Like #glib_major_version, but from the headers used at application compile time, rather than from the library linked against at application run time.

MICRO_VERSION = 0

The micro version number of the GLib library.

Like #gtk_micro_version, but from the headers used at application compile time, rather than from the library linked against at application run time.

MINOR_VERSION = 84

The minor version number of the GLib library.

Like #gtk_minor_version, but from the headers used at application compile time, rather than from the library linked against at application run time.

PRIORITY_DEFAULT = 0

Use this for default priority event sources.

In GLib this priority is used when adding timeout functions with GLib::timeout_add. In GDK this priority is used for events from the X server.

PRIORITY_DEFAULT_IDLE = 200

Use this for default priority idle functions.

In GLib this priority is used when adding idle functions with GLib::idle_add.

PRIORITY_HIGH = -100

Use this for high priority event sources.

It is not used within GLib or GTK.

PRIORITY_HIGH_IDLE = 100

Use this for high priority idle functions.

GTK uses %G_PRIORITY_HIGH_IDLE + 10 for resizing operations, and %G_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.)

PRIORITY_LOW = 300

Use this for very low priority background tasks.

It is not used within GLib or GTK.

REF_COUNT_INIT = -1

Evaluates to the initial reference count for grefcount.

This macro is useful for initializing grefcount fields inside structures, for instance:

|[ typedef struct { grefcount ref_count; char *name; char *address; } Person;

static const Person default_person = { .ref_count = G_REF_COUNT_INIT, .name = "Default name", .address = "Default address", }; ]|

SOURCE_CONTINUE = true

Use this macro as the return value of a GLib::SourceFunc to leave the GLib::Source in the main loop.

SOURCE_REMOVE = false

Use this macro as the return value of a GLib::SourceFunc to remove the GLib::Source from the main loop.

TEST_OPTION_NO_PRGNAME = "no_g_set_prgname"

A value that can be passed as an option to GLib::test_init.

If this option is given, GLib::test_init will not call GLib#prgname=.

TEST_OPTION_NONFATAL_ASSERTIONS = "nonfatal-assertions"

A value that can be passed as an option to GLib::test_init.

If this option is given, assertions will not abort the process, but call GLib::test_fail. Equivalent to GLib::test_set_nonfatal_assertions.
