Property Overview

Property Details

coordinatesNumber[]readonly

Since: ArcGIS API for JavaScript 4.6

An array of x,y coordinates for the point geometry.

declaredClassStringreadonly inherited

Since: ArcGIS API for JavaScript 4.7

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

viewMapView inherited

A reference to the MapView.

Method Overview

Method Details

complete()

Completes drawing the point geometry and fires the draw-complete event. Call this method if the drawing logic needs to be completed other than by double-clicking or pressing the "C" key.

emit(type, event)inherited

Emits an event on the instance. This method should only be used when creating subclasses of this class.

Parameters:

type String The name of the event.

event Object The event payload.

hasEventListener(type){Boolean}inherited

Indicates whether there is an event listener on the instance that matches the provided event name.

Parameter:

type String The name of the event.

Returns:

Type	Description
Boolean	Returns true if the class supports the input event.

on(type, listener){Object}inherited

Registers an event handler on the instance. Call this method to hook an event with a listener.

Parameters:

type String The name of event to listen for.

listener Function The function to call when the event is fired.

Returns:

Type	Description
Object	Returns an event handler with a remove() method that can be called to stop listening for the event. Property Type Description remove Function When called, removes the listener from the event.

Example:

view.on("click", function(event){
  // event is the event handle returned after the event fires.
  console.log(event.mapPoint);
});

Event Overview

{coordinates: Number[],preventDefault: Function,defaultPrevented: Boolean,type: String}

{coordinates: Number[],preventDefault: Function,defaultPrevented: Boolean,type: String}

Event Details

cursor-update

Fires after the pointer moves on the view. It returns the location of the pointer on the view as an array of numbers representing an x,y coordinate pair in the spatial reference of the view.

Properties:

coordinates Number[] An array of numbers representing an x,y coordinate pair in the spatial reference of the view.

preventDefault Function Prevents event propagation bubbling up the event chain.

defaultPrevented Boolean Set to true when preventDefault() is called.

type String The type of the event. For this event, the type is always cursor-update.

Example:

action.on("cursor-update", function (evt) {
  view.graphics.removeAll();
  var point = new Point({
    x: evt.coordinates[0],
    y: evt.coordinates[1],
    spatialReference: view.spatialReference
  });
  var graphic = createGraphic(point);
  view.graphics.add(graphic);
});

draw-complete

Fires after when the user has completed drawing a point. It returns the location of the pointer on the view as an array of numbers representing an x,y coordinate pair in the spatial reference of the view.

Properties:

coordinates Number[] An array of numbers representing an x,y coordinate pair in the spatial reference of the view.

preventDefault Function Prevents event propagation bubbling up the event chain.

defaultPrevented Boolean Set to true when preventDefault() is called.

type String The type of the event. For this event, the type is always draw-complete.

Example:

action.on("draw-complete", function (evt) {
  view.graphics.removeAll();
  var point = new Point({
    x: evt.coordinates[0],
    y: evt.coordinates[1],
    spatialReference: view.spatialReference
  });
  var graphic = createGraphic(point);
  view.graphics.add(graphic);
});
