Brief Description

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

Signals

  • close_request ( )

Signal sent on closing the GraphNode.

Signal sent when the GraphNode is dragged.

  • offset_changed ( )

Signal sent when the GraphNode is moved.

  • raise_request ( )

Signal sent when the GraphNode is requested to be displayed over other ones. Happens on focusing (clicking into) the GraphNode.

  • resize_request ( Vector2 new_minsize )

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.

Member Function Description

  • void clear_all_slots ( )

Disable all input and output slots of the GraphNode.

  • void clear_slot ( int idx )

Disable input and output slot whose index is ‘idx’.

  • Color get_connection_input_color ( int idx )

Return the color of the input connection ‘idx’.

  • int get_connection_input_count ( )

Return the number of enabled input slots (connections) to the GraphNode.

  • Vector2 get_connection_input_position ( int idx )

Return the position of the input connection ‘idx’.

  • int get_connection_input_type ( int idx )

Return the type of the input connection ‘idx’.

  • Color get_connection_output_color ( int idx )

Return the color of the output connection ‘idx’.

  • int get_connection_output_count ( )

Return the number of enabled output slots (connections) of the GraphNode.

  • Vector2 get_connection_output_position ( int idx )

Return the position of the output connection ‘idx’.

  • int get_connection_output_type ( int idx )

Return the type of the output connection ‘idx’.

Return the offset of the GraphNode.

  • int get_overlay ( ) const
  • Color get_slot_color_left ( int idx ) const

Return the color set to ‘idx’ left (input) slot.

  • Color get_slot_color_right ( int idx ) const

Return the color set to ‘idx’ right (output) slot.

  • int get_slot_type_left ( int idx ) const

Return the (integer) type of left (input) ‘idx’ slot.

  • int get_slot_type_right ( int idx ) const

Return the (integer) type of right (output) ‘idx’ slot.

  • bool is_comment ( ) const
  • bool is_selected ( )
  • bool is_slot_enabled_left ( int idx ) const

Return true if left (input) slot ‘idx’ is enabled. False otherwise.

  • bool is_slot_enabled_right ( int idx ) const

Return true if right (output) slot ‘idx’ is enabled. False otherwise.

  • void set_comment ( bool comment )
  • void set_offset ( Vector2 offset )

Set the offset of the GraphNode.

  • void set_overlay ( int overlay )
  • void set_selected ( bool selected )
