JimuMapView

Class

JimuMapView is the view for developers to develop the map-related functions. For example, developers can use the view property of the JimuMapView instance to get the original ArcGIS Maps SDK for JavaScript View, then use the original view to develop the map-related functions. At the same time, JimuMapView also provides properties such as isActive and status to indicate the current status in the map widget.

JimuMapView is a wrapper class for the ArcGIS Maps SDK for JavaScript View. It is created by a map widget using a map DataSource.

import { JimuMapView } from 'jimu-arcgis';

// Add the State interface
interface State {
 extent: __esri.Extent
}

// On an active view change, set the extent State property
onActiveViewChange = (jimuMapView: JimuMapView) => {
 if(!this.extentWatch){
  this.extentWatch = jimuMapView.view.watch('extent', extent => {
    this.setState({
      extent
    })
  });
 }
}

// Use the `JimuMapView` instance from the map widget through the `JimuMapViewComponent` React component
<JimuMapViewComponent useMapWidgetId={this.props.useMapWidgetIds[0]} onActiveViewChange={this.onActiveViewChange}></JimuMapViewComponent>

Class Constructor

new JimuMapView(options: JimuMapViewConstructorOptions): JimuMapView

Parameters

Parameter	Type
`options`	JimuMapViewConstructorOptions

Returns

JimuMapView

Properties

Property	Type	Notes
`dataSourceId`	`string`	The id of the `DataSource` selected to create the map.
`id`	`string`	The id of the `JimuMapView` instance.
`isActive`	`boolean`	The `isActive` property indicates whether the map in the map widget is accessible. For example, for a single-source map, there is a single `JimuMapView` instance, therefore, the `isActive` is always true. With a multi-source map, there are two `JimuMapView` instances. In the multi-source map, the property `isActive` is true for the top `JimuMapView` instance, and false for the one beneath. Upon clicking the switch map tool, the `isActive` properties will switch.
`jimuLayerViews`	`{ [jimuLayerViewId: string]: JimuLayerView }`	The union for all `JimuLayerView` instances and the layer view object wrapper.
`jimuMapTools`	`JimuMapTool[]`	The created map tools (ArcGIS JavaScript API widgets) for this view.
`mapWidgetId`	`string`	The id of the widget creating the `JimuMapView` instance.
`status`	`JimuMapViewStatus`	The status of the `JimuMapView` instance. `JimuMapViewStatus` enumeration members include `"LOADING"`, `"LOADED"` and `"FAILED"`.
`view`	`MapView \| SceneView`	The `view` is the ArcGIS Maps SDK for JavaScript `View`, including a`MapView` or a`SceneView`. In the ArcGIS Maps SDK for JavaScript, the `MapView` and `SceneView` are part of the `__esri` namespace types. Thus, their types are `__esri.MapView` and `__esri.SceneView`.

dataSourceId

Class Property

dataSourceId: string

The id of the DataSource selected to create the map.

id

Class Property

id: string

The id of the JimuMapView instance.

isActive

optional

Class Property

isActive: boolean

The isActive property indicates whether the map in the map widget is accessible. For example, for a single-source map, there is a single JimuMapView instance, therefore, the isActive is always true. With a multi-source map, there are two JimuMapView instances. In the multi-source map, the property isActive is true for the top JimuMapView instance, and false for the one beneath. Upon clicking the switch map tool, the isActive properties will switch.

jimuLayerViews

optional

Class Property

jimuLayerViews: { [jimuLayerViewId: string]: JimuLayerView }

The union for all JimuLayerView instances and the layer view object wrapper.

Type declaration

[jimuLayerViewId: string]: JimuLayerView

jimuMapTools

Class Property

jimuMapTools: JimuMapTool[]

The created map tools (ArcGIS JavaScript API widgets) for this view.

mapWidgetId

Class Property

mapWidgetId: string

The id of the widget creating the JimuMapView instance.

status

Class Property

status: JimuMapViewStatus

The status of the JimuMapView instance. JimuMapViewStatus enumeration members include "LOADING", "LOADED" and "FAILED".

view

Class Property

view: MapView | SceneView

The view is the ArcGIS Maps SDK for JavaScript View, including aMapView or aSceneView. In the ArcGIS Maps SDK for JavaScript, the MapView and SceneView are part of the __esri namespace types. Thus, their types are __esri.MapView and __esri.SceneView.
