### Class

# Shumate PathLayer

#### Description [src]

    final class Shumate.PathLayer : Shumate.Layer
      implements Gtk.Accessible, Gtk.Buildable, Gtk.ConstraintTarget {
      /* No available fields */
    }

A layer displaying line path between inserted `ShumateLocation` objects

This layer shows a connection between inserted objects implementing the `ShumateLocation` interface. This means that both `ShumateMarker` objects and `ShumateCoordinate` objects can be inserted into the layer. Of course, custom objects implementing the `ShumateLocation` interface can be used as well.

#### Constructors

###### shumate_path_layer_new

Creates a new instance of `ShumatePathLayer`.

#### Instance methods

###### shumate_path_layer_add_node

Adds a `ShumateLocation` object to the layer. The node is prepended to the list.

###### shumate_path_layer_get_closed

Gets information whether the path is closed.

###### shumate_path_layer_get_dash

Returns the list of dash segment lengths.

###### shumate_path_layer_get_fill

Checks whether the path is filled.

###### shumate_path_layer_get_fill_color

Gets the path’s fill color.

###### shumate_path_layer_get_nodes

Gets a copy of the list of all `ShumateLocation` objects inserted into the layer. You should free the list but not its contents.

###### shumate_path_layer_get_outline_color

Gets the path’s outline color.

###### shumate_path_layer_get_outline_width

Gets the width of the outline.

###### shumate_path_layer_get_stroke

Checks whether the path is stroked.

###### shumate_path_layer_get_stroke_color

Gets the path’s stroke color.

###### shumate_path_layer_get_stroke_width
