Thanks, but I don't know which function to use to set the association. When using addProviderForScreen(), the association isn't actually set by a function, it's simply implied

I was looking at it from the wrong angle. This works:

class CSSLabel : Label
	string cssPath = "./css/button_label.css";
	StyleContext styleContext;
	CssProvider provider;
	this(string textLabel, string cssName)
		// css stuff
		provider = new CssProvider();
		styleContext = getStyleContext();
		styleContext.addProvider(provider, GTK_STYLE_PROVIDER_PRIORITY_APPLICATION);
	} // this()

I just wasn't going far enough. I'll come up with a more OOP-like version before I take this to the blog. Thanks, Mike.
