  60. Signals
  61. -------
  62. - **close_request** **(** **)**
  63. Signal sent on closing the GraphNode.
  64. - **dragged** **(** :ref:`Vector2<class_vector2>` from, :ref:`Vector2<class_vector2>` to **)**
  65. Signal sent when the GraphNode is dragged.
  66. - **offset_changed** **(** **)**
  67. Signal sent when the GraphNode is moved.
  68. - **raise_request** **(** **)**
  69. Signal sent when the GraphNode is requested to be displayed over other ones. Happens on focusing (clicking into) the GraphNode.
  70. Description
  71. -----------
  72. 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.
