Custom Identify Widget DrawBox onActivate throws drawToolBar null

RichardReinicke — Mon, 08 Feb 2021 11:19:41 GMT

Hello,

I'm new to Web AppBuilder custom widget programming and I try to modify the advanced identify widget by @RobertScheitlin__GISP as a learning project.

I got the DrawBox tool inside my widget to show up in the widget panel and I want to make the DrawBox point draw function active on panelOpen. But when I click on the point draw icon

it fails in DrawBox.js on this.drawToolBar.activate(tool); with drawToolBar being null.

I'm attaching my current state. What am I doing wrong?

Please can someone have a look at my test widget 😕 ? The whole widget is attached.

Thank you very much

Richard,

Your mistake is that you are decalring this.drawBox = new Drawbox. You can remove that line all together, since you have already declared that div to be a DrawBox in the html template.

initDrawBox: function () { //this.drawBox = new Drawbox; this.drawBox.setMap(this.map); this.drawBox.geoTypes = ['POINT']; this.drawBox._initTypes(); this.drawBox.setPointSymbol(new SimpleMarkerSymbol(this.config.symbols.simplemarkersymbol)); this.drawBox.deactivateAfterDrawing = false; },
