module Ext_EventObject:Just as Ext.Element wraps around a native DOM node ...sig..end
Just as 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 = Ext.get("myDiv"); // get reference to an Ext.Element
myDiv.on( // 'on' is shorthand for addListener
"click", // perform an action on click of myDiv
handleClick // reference to the action handler
);
// other methods to do the same:
Ext.EventManager.on("myDiv", 'click', handleClick);
Ext.EventManager.addListener("myDiv", 'click', handleClick);
