A container with connection ports, representing a node in a GraphEdit.

GraphNode allows to create nodes for a GraphEdit graph with customizable content based on its child controls. GraphNode is derived from Container and it is responsible for placing its children on screen. This works similar to 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 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 Control. The properties are grouped by each slot's index in the "Slot" section.

 Signal slot_updated<>( int slot_index=, slot_index:int=, ):Signal

Emitted when any GraphNode's slot is updated.

 bool ignore_invalid_connection_type<>():bool

If true, you can connect ports with different types, even if the connection was not explicitly allowed in the parent GraphEdit.

Returns the type of the output port with the given port_idx.

 Color get_slot_color_left<>( int slot_index=, slot_index:int=, ):Color

 Color get_slot_color_right<>( int slot_index=, slot_index:int=, ):Color

Returns the right (output) Color of the slot with the given slot_index.

 Texture2D get_slot_custom_icon_left<>( int slot_index=, slot_index:int=, ):Texture2D

Returns the left (input) custom Texture2D of the slot with the given slot_index.

 Texture2D get_slot_custom_icon_right<>( int slot_index=, slot_index:int=, ):Texture2D

Returns the right (output) custom Texture2D of the slot with the given slot_index.

 int get_slot_type_left<>( int slot_index=, slot_index:int=, ):int

Returns the left (input) type of the slot with the given slot_index.

 int get_slot_type_right<>( int slot_index=, slot_index:int=, ):int

Returns the right (output) type of the slot with the given slot_index.

 HBoxContainer get_titlebar_hbox<>():HBoxContainer

Returns the HBoxContainer used for the title bar, only containing a Label for displaying the title by default. This can be used to add custom controls to the title bar such as option or close buttons.

 bool is_slot_draw_stylebox<>( int slot_index=, slot_index:int=, ):bool

Returns true if the background StyleBox of the slot with the given slot_index is drawn.

 bool is_slot_enabled_left<>( int slot_index=, slot_index:int=, ):bool

Returns true if left (input) side of the slot with the given slot_index is enabled.

 bool is_slot_enabled_right<>( int slot_index=, slot_index:int=, ):bool

Returns true if right (output) side of the slot with the given slot_index is enabled.

 void set_slot<>( int slot_index=, slot_index:int=, bool enable_left_port=, enable_left_port:bool=, int type_left=, type_left:int=, Color color_left=, color_left:Color=, bool enable_right_port=, enable_right_port:bool=, int type_right=, type_right:int=, Color color_right=, color_right:Color=, Texture2D custom_icon_left=null, custom_icon_left:Texture2D=null, Texture2D custom_icon_right=null, custom_icon_right:Texture2D=null, bool draw_stylebox=true, draw_stylebox:bool=true, ):void

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 GraphEdit (see GraphEdit.add_valid_connection_type()). Keep in mind that the GraphEdit has the final say in accepting the connection. Type compatibility simply allows the GraphEdit.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 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 Control-derived child to the GraphNode.
