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?
