RE: [Dynapi-Help] Where does this need to be poted?

[Brian H. <bg...@ke...>]

Raymond, I noticed your code looks different than mine... Try this. And you
should see what I am talking about.  

var container = new DynLayer(null,0,0,200,200,"e0e0e0");
var insideObj = new DynLayer("Inside",0,0,400,400, "blue"); // larger than
our container...
container.addChild(insideObj);

DragEvent.setDragBoundary(insideObj, {left:0, right:0, top:0, bottom:0});
DragEvent.enableDragEvents(insideObj)
dynapi.document.addChild(container);

Hi,

I'm unable to reproduct the choppy behaviour. Here's the code I'm using:

var container = new
DynLayer(null,0,0,200,200,"e0e0e0");
var insideObj = new DynLayer("Inside",0,0,400,400, "blue"); // larger than
our container...
container.addChild(insideObj);

DragEvent.enableDragEvents(container,insideObj)
dynapi.document.addChild(container);

Could you provide an online demo of this error?
