Bug 62951 – used value support (IE currentStyle)

• Component: CSS
• Status: RESOLVED WONTFIX

please add support for IE currentStyle (i.e. used CSS value). it's vital to oop-app-ui-programming.

current solution is:

this.getDefinedHeightParent=function(n)
{
 var cS,cS2
 while(n!=app.rootElement)
 {
  cS=app.getCS(n)
  if(cS.position=="absolute"||cS.position=="fixed")return n
  if((cS2=n.currentStyle) && n.currentStyle.height!="auto")return n
  else if(!cS2 && n.style.height && n.style.height!="auto") return n //not dry!
  if(!n.parentNode) return n
  n=n.parentNode
 }
 return n
}

this forces user/programmer to add "height:auto;" to every element of an "app-object-source", like:

this.containerHTML=function(param,$class$)
{
return	{
 tabheadsleft:[
 {tagName:"DIV",$id$:"tabheadcontainerleft",style:"height:auto;" //<-------- redundant
 ,children:[$this$.getTabBorderStart.call(this,"left"),{tagName:"DIV",$id$:"tabheadleft",children:["<SPAN style='white-space:nowrap;'>Tab "+this.uid+" "+this.classType+" "+this.chainStr+"</SPAN>"]}	
 ,$this$.getTabBorderEnd.call(this,"left")]}]
...

and/or app notation which sets node.style.height to auto like:

sizes{tabheadcontainerleft:{height:"auto"}}

thank you

i am confused about "used" and "computed". "there should be access to parsed css and element.style without any rendering results, all in one property", is what i tried to say. 

currently, i can't think of a situation where "rendered css" should not be overwritten by element.style. (ok, except "",null etc.) 

scrollbar presence/width/height will still be missed, but can be calculated.

thank you
