operationalLayers: selecting features with drawtool

JamesCrandall

I'm looking for simple example to select features of an operationalLayer by dragging an extent box.  I'm attempting to build a new widget with a button that will activate the drawtool and allow the user to drag a box to select features and deactivate when completed.

Javascript API 3x 

 

Edit to add current code.  

div on the widget's html:

<div class="jimu-btn finish-select" data-dojo-attach-event="click:activateAcknowledgeTool" id="btnActivateSelection">Activate</div>

 

        activateAcknowledgeTool: function () {

            if (!this.drawToolbar) {
                this.setupDrawToolbar();
            }
            this.enableDrawToolbar();
        },
        setupDrawToolbar: function () {
            this.createDrawToolbar();
