I see what you're trying to do. You're trying to

Exactly !
So you
would like the option to be able to pass paraments to
the widget from an the getInline() function? What I
think you're forgetting is the section of getInline()
that calls DynLayer._updateValues(). The
DynLayer._updateValues() function will overwrite your
x,y,w,h,bgcolor,bgimage and html properties that you
would have set from the widget/layer.
Which is fine to me as I'm looking at it considering I would have a 
server side that generates both the inline div, and the javascript 
instruction, so they would be in sync.
Secondly if you were to construct a widget from an
inline layer then you will have to remeber that the
widget's parent will become that of the inline layer.
This could really mess up parant/child relationship if
it's not used properly.
True, but if it's automated, then you're much safer, otherwise, that's 
true, it's a risk. However could that be checked to make sure that 
this.elm.parent == this.parent.elm
In any event I would suggest that you try doing
something like this:
DynLayer.getInline = function (id, p,
a1,a2,a3,a4,a5,a6,a7,a8,a9,a10,a11,a12,a13,a14) {
        var elm;
        var pobj;
        if (!p) pobj = dynapi.document;
        else if (p.isClass && p.isClass('DynElement')) pobj =
p;
        
        if (pobj) {
                if (dynapi.ua.ns4) elm = pobj.doc.layers[id];
                else if (dynapi.ua.ns6) elm =
pobj.doc.getElementsByID(id);
                else if (dynapi.ua.ie) elm = pobj.doc.all[id];
        }
        if (!elm) return alert("DynLayer_inline Error: did
not find element "+id);
        var className=this.prototype._className; //get class
name
        
        var dlyr = eval('new
'+className+'(a1,a2,a3,a4,a5,a6,a7,a8,a9,a10,a11,a12,a13,a14)');
        
        dlyr.setID(id);
        dlyr.parent = pobj;
        dlyr.elm = elm;
        if (dynapi.ua.ns4) dlyr.doc = elm.document;
        DynLayer._updateValues(dlyr);
        DynLayer._assignElement(dlyr,elm);
        DynElement._flagEvent(dlyr,'create');
        return dlyr;
}
function MyWidget(a,b,c){
   // code here;
}
MyWidget.getInline=DynLayer.getInline;

That would work. But I thought about it yesterday night, and I think we 
should take a different approach: create your dynlayers or widget 
exactly as you usually do with their regular constructors.
Now, if you already have the html in the page representing the divs of 
the objects you created, you would call an equivallent to 
document.insertAllChildren() which would be  
assignInlineElementToAllChildren() in the onload. This method would 
crawl the tree of dynlayers, and call on each one:

DynLayer.prototype.assignInlineElement = function {
        var p = this.parent;
        if (!p) pobj = dynapi.document;
        else if (p.isClass && p.isClass('DynElement')) pobj = p;
        
        if (pobj) {
                if (dynapi.ua.ns4) elm = pobj.doc.layers[id];
                else if (dynapi.ua.ns6) elm = pobj.doc.getElementsByID(id);
                else if (dynapi.ua.ie) elm = pobj.doc.all[id];
        }
        if (!elm) return alert("DynLayer_inline Error: did
not find element "+id);

        this.elm = elm;
        if (dynapi.ua.ns4) dlyr.doc = elm.document;
        DynLayer._updateValues(this);
        DynLayer._assignElement(this,elm);
        DynElement._flagEvent(this,'create');
}

That way I think it's a much cleaner design that scales better. What do 
you think ?
