Re: [Dynapi-Help] Help on widgets

Hi,
Firstly check the tutorial here:
http://sourceforge.net/docman/display_doc.php?docid=442&group_id=5757
if you haven't done so already.
There are different widget models depending on the author, this ones from
Pascal Bestebroer.
the principle is that you add 1 main dynlayer:

function widgetname() {
 this.superClass=DynLayer
 this.superClass()
 this.id="widgetname"+(widgetname.Count++)
  return this
}
widgetname.Count=0
widgetname.prototype=new DynLayer()
widgetname.prototype.getSubClass=function() { return widgetname }

You can't add child layers to the layer yet, 'cause it doesn't exist until
the widget has been created,
so you create a listener to trigger oncreate, and add child layers then.

Basically in your first example you are adding a child layer to something
which doesn't exist yet.

Hope that helps
Richard :)
