Class StyleInjectorHelper

java.lang.Object

com.sencha.gxt.core.client.resources.StyleInjectorHelper

public class StyleInjectorHelper
extends Object

Utility methods for injecting styles. These methods, like those in StyleInjector, bypass the use of com.google.gwt.resources.client.CssResource#ensureInjected() to allow for immediate injection. These methods will inject CssResources only once as long as all injections are performed using this helper class.
