[Laszlo-user] Where in the runtime would a CSS style like this be found: Skin[name="mySkin"]

[Antun Karlovac]

Hi Tucker,

Thanks for your reply. What I'm trying to do is to get my CSS exploring 
tool to work in the latest version of Webtop. Previously, Webtop used 
CSS applied directly to views/classes. Now, some CSS is applied to 
instances of a class called Skin.

So a developer says:

 >> Skin[name="mySkin"] {
 >>    backgroundColor: #ff0000;
 >>    textColor: #00ff00;
 >> }

The skins use normal style bindings, e.g.

<class name="Skin" extends="node">
     <attribute name="mouseOverFillColor"
                value="$style{'mouseOverFillColor'}"/>
</class>

However, when I get a reference to a skin and try to find out the CSS 
that applies to it, e.g.

LzCSSStyle.getRulesCache(gWebtop.skinManager.silver)

... I get an empty array. In the debugger, I can verify that the 
style-bound class attributes of gWebtop.skinManager.silver are in fact set:

gWebtop.skinManager.silver.mouseOverFillColor is actually set to the 
value specified in the CSS file.

I'm cc-ing Maynard on this, since he's the person on the Webtop team 
familiar with CSS, in case it rings any bells. However, from looking at 
the code, I don't see anything funny in the way that skins are styled 
(vs. any other view) in Webtop.
