GraphNode
=========

**Inherits:** :ref:`GraphElement<class_GraphElement>` **<** :ref:`Container<class_Container>` **<** :ref:`Control<class_Control>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

A container with connection ports, representing a node in a :ref:`GraphEdit<class_GraphEdit>`.

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

**GraphNode** allows to create nodes for a :ref:`GraphEdit<class_GraphEdit>` graph with customizable content based on its child controls. **GraphNode** is derived from :ref:`Container<class_Container>` and it is responsible for placing its children on screen. This works similar to :ref:`VBoxContainer<class_VBoxContainer>`. Children, in turn, provide **GraphNode** with so-called slots, each of which can have a connection port on either side.

Each **GraphNode** slot is defined by its index and can provide the node with up to two ports: one on the left, and one on the right. By convention the left port is also referred to as the **input port** and the right port is referred to as the **output port**. Each port can be enabled and configured individually, using different type and color. The type is an arbitrary value that you can define using your own considerations. The parent :ref:`GraphEdit<class_GraphEdit>` will receive this information on each connect and disconnect request.

Slots can be configured in the Inspector dock once you add at least one child :ref:`Control<class_Control>`. The properties are grouped by each slot's index in the "Slot" section.

\ **Note:** While GraphNode is set up using slots and slot indices, connections are made between the ports which are enabled. Because of that :ref:`GraphEdit<class_GraphEdit>` uses the port's index and not the slot's index. You can use :ref:`get_input_port_slot<class_GraphNode_method_get_input_port_slot>` and :ref:`get_output_port_slot<class_GraphNode_method_get_output_port_slot>` to get the slot index from the port index.

Sets properties of the slot with the given ``slot_index``.

If ``enable_left_port``/``enable_right_port`` is ``true``, a port will appear and the slot will be able to be connected from this side.

With ``type_left``/``type_right`` an arbitrary type can be assigned to each port. Two ports can be connected if they share the same type, or if the connection between their types is allowed in the parent :ref:`GraphEdit<class_GraphEdit>` (see :ref:`GraphEdit.add_valid_connection_type<class_GraphEdit_method_add_valid_connection_type>`). Keep in mind that the :ref:`GraphEdit<class_GraphEdit>` has the final say in accepting the connection. Type compatibility simply allows the :ref:`GraphEdit.connection_request<class_GraphEdit_signal_connection_request>` signal to be emitted.

Ports can be further customized using ``color_left``/``color_right`` and ``custom_icon_left``/``custom_icon_right``. The color parameter adds a tint to the icon. The custom icon can be used to override the default port dot.

Additionally, ``draw_stylebox`` can be used to enable or disable drawing of the background stylebox for each slot. See :ref:`slot<class_GraphNode_theme_style_slot>`.

Individual properties can also be set using one of the ``set_slot_*`` methods.

\ **Note:** This method only sets properties of the slot. To create the slot itself, add a :ref:`Control<class_Control>`-derived child to the GraphNode.
