Cogl.UserDataKey

const Cogl = imports.gi.Cogl;

let userDataKey = new Cogl.UserDataKey({
    unused: value
});

A Cogl.UserDataKey is used to declare a key for attaching data to a Cogl.Object using cogl_object_set_user_data. The typedef only exists as a formality to make code self documenting since only the unique address of a Cogl.UserDataKey is used.

Typically you would declare a static Cogl.UserDataKey and set private data on an object something like this:

|[ static CoglUserDataKey path_private_key;

static void destroy_path_private_cb (void *data) { g_free (data); }

static void my_path_set_data (CoglPath *path, void *data) { cogl_object_set_user_data (COGL_OBJECT (path), &private_key, data, destroy_path_private_cb); } ]|
