[Dynapi-Widgetdev] Bug in the ScrollPane widget?

[<AFr...@ba...>]

Is there a bug in the ScrollPane widget that prevents you from creating
your
own widget that adds the ScrollPane widget as a child?  If I use
this.addChild(new ScrollPane()) I do not get scrollbars.  If I use
DynAPI.document.addChild(this.scrollObj) I get scrollbars.

I have tried several of the current snapshots from the past month and
I have the same problem.

Here is the code for what I am attempting to do:

function Grid1()
{
  this.DynLayer = DynLayer;
  this.DynLayer();

  this.setSize(200, 200);
  this.setBgColor("silver");

  this.grid = new DynLayer();
  this.grid.setSize(500, 500);
  this.grid.setBgColor("blue");
  this.grid.setHTML("<h1>a<br />b<br />c<br />d<br />e<br />f<br /></h1>");

  this.scrollObj = this.addChild(new ScrollPane(this.grid));
  this.scrollObj.moveTo(25, 25);
  this.scrollObj.setSize(this.getWidth() - 30, this.getHeight() - 30);
}

Grid1.prototype = new DynLayer;

If I change the line from:

     this.scrollObj = this.addChild(new ScrollPane(this.grid));

to
     this.scrollObj = new ScrollPane(this.grid);
     DynAPI.document.addChild(this.scrollObj);

the ScrollPane displays correctly.  Otherwise, the ScrollPane does not
display
any scrollbars.

Thanks,

Andy

Yes this is a bug, probably something to do with dynimage, sometimes the
images show after a few refreshes.
I found the problem only really shows up if the files are on a server, from
local machine they are ok.
The bug is posted, let's hope someone finds the solution soon.

Cheers,
