Brief Description
-----------------

A GraphNode is a container with several input and output slots allowing connections between GraphNodes. Slots can have different, incompatible types.

Signals
-------

.. _class_GraphNode_close_request:

- **close_request** **(** **)**

Signal sent on closing the GraphNode.

.. _class_GraphNode_dragged:

- **dragged** **(** :ref:`Vector2<class_vector2>` from, :ref:`Vector2<class_vector2>` to **)**

Signal sent when the GraphNode is dragged.

.. _class_GraphNode_resize_request:

- **resize_request** **(** :ref:`Vector2<class_vector2>` new_minsize **)**


Member Variables
----------------

  .. _class_GraphNode_comment:

- :ref:`bool<class_bool>` **comment**

  .. _class_GraphNode_offset:

- :ref:`Vector2<class_vector2>` **offset** - The offset of the GraphNode, relative to the scroll offset of the :ref:`GraphEdit<class_graphedit>`. Note that you cannot use position directly, as :ref:`GraphEdit<class_graphedit>` is a :ref:`Container<class_container>`.

Enums
-----

  .. _enum_GraphNode_Overlay:

enum **Overlay**

- **OVERLAY_DISABLED** = **0**
- **OVERLAY_BREAKPOINT** = **1**
- **OVERLAY_POSITION** = **2**


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

A GraphNode is a container defined by a title. It can have 1 or more input and output slots, which can be enabled (shown) or disabled (not shown) and have different (incompatible) types. Colors can also be assigned to slots. A tuple of input and output slots is defined for each GUI element included in the GraphNode. Input and output connections are left and right slots, but only enabled slots are counted as connections.
