Emit not sent

[LefterisKoumis]

I am trying to modify the Screening widget. In one of its subfolders, "drawtool" in the file drawtool,js it emits the completion of the draw by using:

this.emit("onDrawComplete", [graphics]);

to the widget.js

this.own(on(this._drawTool, "onDrawComplete", lang.hitch(this, function (graphics) {
        this._initToCreateAOIBuffer(graphics);
      })));

I created my own file under the drawtool folder and I need to emit the same event from that file:

this.emit("onDrawComplete", [thePMPTgraphic]);    

However, the emit is not working. The issue is not the thePMPTgraphic,  since it was tested. 

Any ideas why the emit works in drawtools.js and not in the custom file? I have other functions in the custom file and are working properly.

@LefterisKoumis 

Have you added the 

'dojo/Evented' module to your define array and the declare array like the drawTool.js file has? 

this.emit comes from that module.

THanks Robert. The Evented module is present and is still not working. 

[RobertScheitlin__GISP]

@LefterisKoumis 

and you are sure Evented is part of your declare array too?

return declare([BaseWidget, _WidgetsInTemplateMixin, Evented], {

[LefterisKoumis]

Positive.

OK that looks good so it must be the listener then.

      this.own(on(this._drawTool, "onDrawComplete", lang.hitch(this, function (graphics) {
        this._initToCreateAOIBuffer(graphics);
      })));

The above code is only listening for the onDrawComplete event on the this_drawTool. So have you modified the widget.js to listen to the event on your custom component?

[LefterisKoumis]

I declared my component

'./drawTool/Screening_pmtools',
-----
], function (
----
Screening_pmtools,
-----

then I called it:

 this._drawPM = new Screening_pmtools()
      this.own(on(this._drawPM, "onDrawComplete", lang.hitch(this, function (graphics) {
        console.log(graphics)
        this._initToCreateAOIBuffer(graphics);
      })));

[RobertScheitlin__GISP]

hmm... Have you tried to console.log you component out to see if it is what it's suppose to be?

this._drawPM = new Screening_pmtools();
console.log(this._drawPM);

[LefterisKoumis]

I did now and it is empty. I don't understand why it is empty since it is declared properly as shown in previous posting.

[RobertScheitlin__GISP]

does your "Screening_pmtools" constructor function have any arguments?

 Try putting some console.log or break points in your "Screening_pmtools"
