I disagree the w & h should be defaulted to null in the
constructor and not be touched until _assignElement.

A user/developer knowing that pixels are supported
would use px in style sheets as in the same way
lyr=new DynLayer('z',10,10,'100%',100%')
wouldn't be expected to work in any case.

Defaults as explained above. Then in assignElement:
1) call new methods getElmWidth() & getElmHeight()
to satisfy the style sheet requirement
then if the user/developer hasn't specified a style object
or class
2) call getContentWidth() & getContentHeight() to satisfy
the auto size requirement (single character DynLayers etc)

Re: [Dynapi-Dev] DynLayer and setClass()

[Raymond I. <xw...@ya...>]

Kevin,

Proposed DynLayer functions for use within
assignElement(): 

p.getElmWidth = function(){	
	var w = parseInt(this.css.width);
	if(isNaN(w)) w=this.getContentWidth();
	return w;
};
p.getElmHeight = function(){
	var h = parseInt(this.css.height);
	if(isNaN(h)) h=this.getContentWidth();
	return h;
};

while DynLayer._assignElement will now use:

if (dlyr.html!=null && dlyr.html!='' && (dlyr.w==null
|| dlyr.h==null)) {
	var cw = (dlyr.w==null)? dlyr.getElmWidth() : null;
	var ch = (dlyr.h==null)? dlyr.getElmHeight() : null;
	dlyr.setSize(cw,ch);
}


Please run a performance test on this to see if it is
ok.


Any comments, suggestions?

This will allow DynAPI to set the width/height of the
layer if its was defined via a style sheet.

For example, lyr.setClass('myclass',true) will cause
dynapi to use "myclass" to setup the css properties
for the DynLayer. 

If no css width/height were defined in the style sheet
then the content width/height will be used as the
dynlayer's width/height.

Not sure if it will work. Is getContentWidth/Height
ever called and on what browsers did you see this?

I had come up with a cross browser version:

p.getElmWidth=function() {
  var r=this.elm, s=this.css;
  if(r) { s=s.clip||s; return s.width||r.offsetWidth; }
  else return null;
};
p.getElmHeight=function() {
  var r=this.elm, s=this.css;
  if(r) { s=s.clip||s; return s.height||r.offsetHeight; }
  else return null;
};

Unfortunately after HTML has been written the
element has style anyway. So testing for no style
value didn't work for me. We need something else.
Perhaps:
lyr=new DynL:ayer('a',100,100);
setClass('redbg','auto');
will pull bgColor from the class 'redbg' and 'auto' to
force getContentWidth/Height() (offsetWidth/Height)
rather than looking at element style (width/height)
which may contain valid size of 'a' or dynlayer size
defined in class 'redbg'.

Whenever w==null and h==null then
getContenWidth/Height is called to set the size of the
layer.

Will the above get the width of the layer when it's
defined inside the style sheet?
