| addKeyListener( Number/Array/Object/String key, Function fn, [Object scope] ) : Ext.KeyMap Convenience method for constructing a KeyMap Convenience method for constructing a KeyMap Parameters: `key` : Number/Array/Object/String Either a string with the keys to listen for, the numeric key code, array of key codes or an object with the following options: `{key: (number or array), shift: (true/false), ctrl: (true/false), alt: (true/false)}` `fn` : Function The function to call `scope` : Object (optional) The scope (`this` reference) in which the specified function is executed. Defaults to this Element. Returns: `Ext.KeyMap` The KeyMap created | Element
| addKeyMap( Object config ) : Ext.KeyMap Creates a KeyMap for this element Creates a KeyMap for this element Parameters: `config` : Object The KeyMap config. See Ext.KeyMap for more details Returns: `Ext.KeyMap` The KeyMap created | Element
- | addListener( String eventName, Function fn, [Object scope], [Object options] ) : Ext.Element Appends an event handler to this element. The shorthand version on is equivalent. Appends an event handler to this element. The shorthand version on is equivalent. Parameters: `eventName` : String The name of event to handle. `fn` : Function The handler function the event invokes. This function is passed the following parameters: evt : EventObject The EventObject describing the event. el : HtmlElement The DOM element which was the target of the event. Note that this may be filtered by using the `delegate` option. o : Object The options object from the addListener call. `scope` : Object (optional) The scope (`this` reference) in which the handler function is executed. If omitted, defaults to this Element.. `options` : Object (optional) An object containing handler configuration properties. This may contain any of the following properties: scope Object : The scope (`this` reference) in which the handler function is executed. If omitted, defaults to this Element. delegate String: A simple selector to filter the target or look for a descendant of the target. See below for additional details. stopEvent Boolean: True to stop the event. That is stop propagation, and prevent the default action. preventDefault Boolean: True to prevent the default action stopPropagation Boolean: True to prevent event propagation normalized Boolean: False to pass a browser event to the handler function instead of an Ext.EventObject target Ext.Element: Only call the handler if the event was fired on the target Element, not if the event was bubbled up from a child node. delay Number: The number of milliseconds to delay the invocation of the handler after the event fires. single Boolean: True to add a handler to handle just the next firing of the event, and then remove itself. buffer Number: Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place. Combining Options In the following examples, the shorthand form on is used rather than the more verbose addListener. The two are equivalent. Using the options argument, it is possible to combine different types of listeners: A delayed, one-time listener that auto stops the event and adds a custom argument (forumId) to the options object. The options object is available as the third parameter in the handler function. Code:
      el.on('click', this.onClick, this, {
          single: true,
          delay: 100,
          stopEvent : true,
          forumId: 4
      });
  Attaching multiple handlers in 1 call The method also allows for a single argument to be passed which is a config object containing properties which specify multiple handlers. Code:
      el.on({
          'click' : {
              fn: this.onClick,
              scope: this,
              delay: 100
          },
          'mouseover' : {
              fn: this.onMouseOver,
              scope: this
          },
          'mouseout' : {
              fn: this.onMouseOut,
              scope: this
          }
      });
  Or a shorthand syntax: Code:
      el.on({
          'click' : this.onClick,
          'mouseover' : this.onMouseOver,
          'mouseout' : this.onMouseOut,
          scope: this
      });
  delegate This is a configuration option that you can pass along when registering a handler for an event to assist with event delegation. Event delegation is a technique that is used to reduce memory consumption and prevent exposure to memory-leaks. By registering an event for a container element as opposed to each element within a container. By setting this configuration option to a simple selector, the target element will be filtered to look for a descendant of the target. For example:
      // using this markup:
      <div id='elId'>
          <p id='p1'>paragraph one</p>
          <p id='p2' class='clickable'>paragraph two</p>
          <p id='p3'>paragraph three</p>
      </div>
      // utilize event delegation to registering just one handler on the container element:
      el = Ext.get('elId');
      el.on(
          'click',
          function(e,t) {
              // handle click
              console.info(t.id); // 'p2'
          },
          this,
          {
              // filter the target element to be a descendant with the class 'clickable'
              delegate: '.clickable'
          }
      );
Returns: `Ext.Element` this | Element
| alignTo( Mixed element, String position, [Array offsets], [Boolean/Object animate] ) : Ext.Element Aligns this element with another element relative to the specified anchor points. If the other element is the documen... Aligns this element with another element relative to the specified anchor points. If the other element is the document it aligns it to the viewport. The position parameter is optional, and can be specified in any one of the following formats: Blank: Defaults to aligning the element's top-left corner to the target's bottom-left corner ("tl-bl"). One anchor (deprecated): The passed anchor position is used as the target element's anchor point. The element being aligned will position its top-left corner (tl) to that point. This method has been deprecated in favor of the newer two anchor syntax below. Two anchors: If two values from the table below are passed separated by a dash, the first value is used as the element's anchor point, and the second value is used as the target's anchor point. In addition to the anchor points, the position parameter also supports the "?" character. If "?" is passed at the end of the position string, the element will attempt to align as specified, but the position will be adjusted to constrain to the viewport if necessary. Note that the element being aligned might be swapped to align to a different position than that specified in order to enforce the viewport constraints. Following are all of the supported anchor positions:
    Value  Description
    -----  -----------------------------
    tl     The top left corner (default)
    t      The center of the top edge
    tr     The top right corner
    l      The center of the left edge
    c      In the center of the element
    r      The center of the right edge
    bl     The bottom left corner
    b      The center of the bottom edge
    br     The bottom right corner
Example Usage:
    // align el to other-el using the default positioning ("tl-bl", non-constrained)
    el.alignTo("other-el");

    // align the top left corner of el with the top right corner of other-el (constrained to viewport)
    el.alignTo("other-el", "tr?");

    // align the bottom right corner of el with the center left edge of other-el
    el.alignTo("other-el", "br-l?");

    // align the center of el with the bottom left corner of other-el and
    // adjust the x position by -6 pixels (and the y position by 0)
    el.alignTo("other-el", "c-bl", [-6, 0]);

Wraps the specified element with a special 9 element markup/CSS block that renders by default as a gray container with a gradient background, rounded corners and a 4-way shadow. This special markup is used throughout Ext when box wrapping elements (Ext.Button, Ext.Panel when `frame=true`, Ext.Window). The markup is of this form:
    Ext.Element.boxMarkup =
        '<div class="{0}-tl"><div class="{0}-tr"><div class="{0}-tc"></div></div></div>

Example usage:
    // Basic box wrap
        Ext.get("foo").boxWrap();

        // You can also add a custom class and use CSS inheritance rules to customize the box look.

Gets the globally shared flyweight Element, with the passed node as the active element. Do not store a reference to this element - the dom node can be overwritten by other code. Shorthand of Ext.Element.fly Use this to make one-time references to DOM elements which are not going to be accessed again either by application code, or by Ext's classes.
