Method Summary

static void	addEventListener_(java.lang.Object element, java.lang.String eventName, java.lang.Runnable _handler, java.lang.Object context)
static boolean	addEventListener_simple(java.lang.Object object, java.lang.String evt, java.lang.Object func, boolean capture) Add an event listener to an object
static void	addEventListener(java.lang.Object element, java.lang.String eventName, java.lang.Runnable handler) safe context and compatible way of register events with a runnable handler
static Element	createButton(Element parent, java.lang.String label, java.lang.Runnable clickHandler)
static Element	createElement(Element parent, java.lang.String tagname, java.lang.Object... attrs)
static Element	createElementRec(java.lang.Object obj) recursively creates markup from js object like shown :
static Element	createLabel(Element parent, java.lang.String text)
static HTMLTable	createTable(java.lang.Object tableObj, int rowCount, int columnCount)
static java.lang.String	getAttribute(Element el, java.lang.String name)

static void	printIn(Element parent, java.lang.String s)
static boolean	removeEventListener(java.lang.Object object, java.lang.String evt, java.lang.Object func, boolean capture) Removes an event listener
static boolean	setAttribute(Element el, java.lang.String name, java.lang.Object val) this is a slow but safe implementation. native setAttribute can throw very native exceptions (event uncacheable by firebug) when attr names are invalid
static void	setAttributes(Element el, java.lang.Object... attrs)
static void	setStyle(Element el, java.lang.String name, java.lang.String value)
static void	setStyles(Element el, java.lang.String... attrs) you must pass the javascript property name instead the css name.
