</span> * @class Ext.EventObject

Just as {@link Ext.Element} wraps around a native DOM node, Ext.EventObject
wraps the browser's native event-object normalizing cross-browser differences,
such as which mouse button is clicked, keys pressed, mechanisms to stop
event-propagation along with a method to prevent default actions from taking place.

For example:

    function handleClick(e, t){ // e is not a standard event object, it is a Ext.EventObject
        e.preventDefault();
        var target = e.getTarget(); // same as t (the target HTMLElement)
        ...
    }

    var myDiv = {@link Ext#get Ext.get}(&quot;myDiv&quot;);  // get reference to an {@link Ext.Element}
    myDiv.on(         // 'on' is shorthand for addListener
        &quot;click&quot;,      // perform an action on click of myDiv
        handleClick   // reference to the action handler
    );

    // other methods to do the same:
    Ext.EventManager.on(&quot;myDiv&quot;, 'click', handleClick);
    Ext.EventManager.addListener(&quot;myDiv&quot;, 'click', handleClick);
