Properties:

• public string description { owned get; set; }
• public uint length { get; }

Creation methods:

• public Path ()
  Creates a new Path instance with no nodes.
• public Path.with_description (string desc)
  Creates a new Path instance with the nodes described in desc.

Methods:

• public void @foreach (PathCallback callback)
  Calls a function for each node of the path.
• public void add_cairo_path (Path cpath)
  Add the nodes of the Cairo path to the end of this.
• public void add_close ()
  Adds a CLOSE type node to the path.
• public void add_curve_to (int x_1, int y_1, int x_2, int y_2, int x_3, int y_3)
  Adds a CURVE_TO type node to the path.
• public void add_line_to (int x, int y)
  Adds a LINE_TO type node to the path.
• public void add_move_to (int x, int y)
  Adds a MOVE_TO type node to the path.
• public void add_node (PathNode node)
  Adds node to the end of the path.
• public void add_rel_curve_to (int x_1, int y_1, int x_2, int y_2, int x_3, int y_3)
  Same as add_curve_to except the coordinates are relative to the previous node.
• public void add_rel_line_to (int x, int y)
  Same as add_line_to except the coordinates are relative to the previous node.
• public void add_rel_move_to (int x, int y)
  Same as add_move_to except the coordinates are relative to the previous node.
• public bool add_string (string str)
  Adds new nodes to the end of the path as described in str .
• public void clear ()
  Removes all nodes from the path.
• public string get_description ()
  Returns a newly allocated string describing the path in the same format as used by add_string.
• public uint get_length ()
  Retrieves an approximation of the total length of the path.
• public uint get_n_nodes ()
  Retrieves the number of nodes in the path.
• public PathNode get_node (uint index_)
  Retrieves the node of the path indexed by index.
• public SList<unowned PathNode?> get_nodes ()
  Returns a SList of PathNodes.
• public uint get_position (double progress, out Knot position)
  The value in progress represents a position along the path where 0.0 is the beginning and 1.0 is the end of the path.
• public void insert_node (int index_, PathNode node)
  Inserts node into the path before the node at the given offset.
• public void remove_node (uint index_)
  Removes the node at the given offset from the path.
• public void replace_node (uint index_, PathNode node)
  Replaces the node at offset index_ with node .
• public bool set_description (string str)
  Replaces all of the nodes in the path with nodes described by str.
• public void to_cairo_path (Context cr)
  Add the nodes of the ClutterPath to the path in the Cairo context.
