Signals
-------

-  **script_changed**  **(** **)**

Numeric Constants
-----------------

- **NOTIFICATION_POSTINITIALIZE** = **0** --- Called right when the object is initialized. Not available in script.
- **NOTIFICATION_PREDELETE** = **1** --- Called before the object is about to be deleted.
- **CONNECT_DEFERRED** = **1** --- Connect a signal in deferred mode. This way, signal emissions are stored in a queue, then set on idle time.
- **CONNECT_PERSIST** = **2** --- Persisting connections are saved when the object is serialized to file.
- **CONNECT_ONESHOT** = **4** --- One shot connections disconnect themselves after emission.

Description
-----------

Base class for all non built-in types. Everything not a built-in type starts the inheritance chain from this class.

Objects do not manage memory, if inheriting from one the object will most likely have to be deleted manually (call the :ref:`free<class_Object_free>` function from the script or delete from C++).

Some derivates add memory management, such as :ref:`Reference<class_reference>` (which keeps a reference count and deletes itself automatically when no longer referenced) and :ref:`Node<class_node>`, which deletes the children tree when deleted.

Objects export properties, which are mainly useful for storage and editing, but not really so much in programming. Properties are exported in :ref:`_get_property_list<class_Object__get_property_list>` and handled in :ref:`_get<class_Object__get>` and :ref:`_set<class_Object__set>`. However, scripting languages and C++ have simpler means to export them.

Objects also receive notifications (:ref:`_notification<class_Object__notification>`). Notifications are a simple way to notify the object about simple events, so they can all be handled together.
