SimpleFillSymbol | API Reference | ArcGIS Maps SDK for JavaScript 4.33

ESM: import SimpleFillSymbol from "@arcgis/core/symbols/SimpleFillSymbol.js";

CDN: const SimpleFillSymbol = await $arcgis.import("@arcgis/core/symbols/SimpleFillSymbol.js");

Class: @arcgis/core/symbols/SimpleFillSymbol

Since: ArcGIS Maps SDK for JavaScript 4.0

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.

Example

let symbol = {
  type: "simple-fill",  // autocasts as new SimpleFillSymbol()
  color: [ 51,51, 204, 0.9 ],
  style: "solid",
  outline: {  // autocasts as new SimpleLineSymbol()
    color: "white",
    width: 1
  }
};

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
};

addHandles

Inherited

Method addHandles(handleOrHandles, groupKey)

Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, addHandles added at 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 }
);

this.addHandles(handle);

// Destroy the object
this.destroy();

Parameters

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.

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

Inherited

Method fromJSON(json){* |null |undefined}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.

Returns

Type Description * | null | undefined Returns a new instance of this class.

hasHandles

Inherited

Method hasHandles(groupKey){Boolean}

Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, hasHandles added at 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

Inherited

Method removeHandles(groupKey)

Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, removeHandles added at 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");
