Editing Graphics

UmarSharif — Thu, 08 Oct 2015 03:52:45 GMT

I am developing a drawing tool (circle/line/polygon etc.) with editing capabilities. I have a questions:

I want to scale a graphic object without editing tool (I don't want to click on graphic object and set scale as done in editing widget) How this can be achieved?

Look here: https://developers.arcgis.com/javascript/jsapi/graphic-amd.html#setgeometry

What you'll do is find your graphic object, and then it'll depend on the shape.

Make it easier on yourself and var graphic = // code to retrieve the graphic you want to edit;

Then you'll need to get the geometry for the shape you're editing. If it's a circle, I think it's graphic.geometry.rings. Change the rings collection, set graphic.geometry.rings = rings, and then geometry.setGeometry(graphic.geometry);

The easier example is editing a point from user in put x and y.

graphic.geometry.setX(4);

graphic.geometry.setY(1);

graphic.setGeometry(graphic.geometry);

You see? You're changing the geometry then sort of setting itself with the geometry you changed.

I hope that's what you meant by editing the scale.

... or maybe this is what you want for scale. http://gis.stackexchange.com/questions/121798/how-to-set-scale-range-for-a-graphic-layer-in-arcgis-api

I don't want to click on a graphic to edit it. I want to edit it dynmically

Look at my code example above. Remove setGeometry and insert setScale, and apply the proper properties to it. That's how you programmitcally change the graphic scale.

A link to my working code? No, I don't have a link that has this code. In my initial reply to this thread, I provided a link to the class you need, and a code snippet example.
