SimpleFillSymbol is used for rendering 2D polygons in either a MapView or a SceneView. It can be filled with a solid color, or a pattern. In addition, the symbol can have an optional outline, which is defined by a SimpleLineSymbol.

SimpleFillSymbols may be applied to polygon features in a FeatureLayer or an individual Graphic.

Fill symbols may also be used to symbolize 2D polygon features in a 3D SceneView. However, it is recommended you use PolygonSymbol3D instead. The image below depicts a FeatureLayer whose graphics are styled with a SimpleFillSymbol.

Property Details

Autocasts from Object|Number[]|String

The color of the symbol. This can be autocast with an array of rgb(a) values, named string, hex string or an hsl(a) string, an object with r, g, b, and a properties, or a Color object.

Default Value:[0, 0, 0, 0.25] - black, semitransparent
Examples
// CSS color string
symbol.color = "dodgerblue";
// HEX string
symbol.color = "#33cc33";
// array of RGBA values
symbol.color = [51, 204, 51, 0.3];
// object with rgba properties
symbol.color = {
  r: 51,
  g: 51,
  b: 204,
  a: 0.7
};

The name of the class. The declared class name is formatted as esri.folder.className.

The outline of the polygon.

Example
let sym = {
  type: "simple-fill",  // autocasts as new SimpleFillSymbol()
  color: "red",
  outline: {  // autocasts as new SimpleLineSymbol()
    color: [128, 128, 128, 0.5],
    width: "0.5px"
  }
};
style String

The fill style. Possible values are listed in the table below:

Method Details

addHandles(handleOrHandles, groupKey)inherited
Since: ArcGIS Maps SDK for JavaScript 4.25

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.

// Manually manage handles
const handle = reactiveUtils.when(
  () => !view.updating,
  () => {
    wkidSelect.disabled = false;
  },
  { once: true }
);

// Handle gets removed when the object is destroyed.
this.addHandles(handle);
Parameters
handleOrHandles WatchHandle|WatchHandle[]

Handles marked for removal once the object is destroyed.

groupKey *
optional

Key identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.

clone(){SimpleFillSymbol}

Creates a deep clone of the symbol.

Returns
Type Description
SimpleFillSymbol A deep clone of the object that invoked this method.
Example
// Creates a deep clone of the graphic's symbol
let symLyr = graphic.symbol.clone();
fromJSON(json){*}static

Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product. The object passed into the input json parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Parameter
json Object

A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.

Returns
Type Description
* Returns a new instance of this class.
hasHandles(groupKey){Boolean}inherited
Since: ArcGIS Maps SDK for JavaScript 4.25

Returns true if a named group of handles exist.

Parameter
groupKey *
optional

A group key.

Returns
Type Description
Boolean Returns true if a named group of handles exist.
Example
// Remove a named group of handles if they exist.
if (obj.hasHandles("watch-view-updates")) {
  obj.removeHandles("watch-view-updates");
}
removeHandles(groupKey)inherited
Since: ArcGIS Maps SDK for JavaScript 4.25

Removes a group of handles owned by the object.

Parameter
groupKey *
optional

A group key or an array or collection of group keys to remove.

Example
obj.removeHandles(); // removes handles from default group

obj.removeHandles("handle-group");
obj.removeHandles("other-handle-group");
toJSON(){Object}inherited

Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.

Returns
Type Description
Object The ArcGIS portal JSON representation of an instance of this class.
