/**
 * @class Date
 *
 * The date parsing and format syntax is a subset of
 * <a href="http://www.php.net/date">PHP's date() function</a>, and the formats that are
 * supported will provide results equivalent to their PHP versions.
 *
 * Following is the list of all currently supported formats:
 *<pre>
Sample date:
'Wed Jan 10 2007 15:05:01 GMT-0600 (Central Standard Time)'

Format  Output      Description
------  ----------  --------------------------------------------------------------
  d      10         Day of the month, 2 digits with leading zeros
  D      Wed        A textual representation of a day, three letters
  j      10         Day of the month without leading zeros
  l      Wednesday  A full textual representation of the day of the week
  S      th         English ordinal day of month suffix, 2 chars (use with j)
  w      3          Numeric representation of the day of the week
  z      9          The julian date, or day of the year (0-365)
  W      01         ISO-8601 2-digit week number of year, weeks starting on Monday (00-52)
  F      January    A full textual representation of the month
  m      01         Numeric representation of a month, with leading zeros
  M      Jan        Month name abbreviation, three letters
  n      1          Numeric representation of a month, without leading zeros
  t      31         Number of days in the given month
  L      0          Whether it's a leap year (1 if it is a leap year, else 0)
  Y      2007       A full numeric representation of a year, 4 digits
  y      07         A two digit representation of a year
  a      pm         Lowercase Ante meridiem and Post meridiem
  A      PM         Uppercase Ante meridiem and Post meridiem
  g      3          12-hour format of an hour without leading zeros
  G      15         24-hour format of an hour without leading zeros
  h      03         12-hour format of an hour with leading zeros
  H      15         24-hour format of an hour with leading zeros
  i      05         Minutes with leading zeros
  s      01         Seconds, with leading zeros
  O      -0600      Difference to Greenwich time (GMT) in hours (Allows +08, without minutes)
  P      -06:00     Difference to Greenwich time (GMT) with colon between hours and minutes
  T      CST        Timezone setting of the machine running the code
  Z      -21600     Timezone offset in seconds (negative if west of UTC, positive if east)
</pre>
 *
 * Example usage (note that you must escape format specifiers with '\\' to render them as character literals):
 * <pre><code>
var dt = new Date('1/10/2007 03:05:01 PM GMT-0600');
document.write(dt.format('Y-m-d'));                         //2007-01-10
document.write(dt.format('F j, Y, g:i a'));                 //January 10, 2007, 3:05 pm
document.write(dt.format('l, \\t\\he dS of F Y h:i:s A'));  //Wednesday, the 10th of January 2007 03:05:01 PM
 </code></pre>
 *
 * Here are some standard date/time patterns that you might find helpful.  They
 * are not part of the source of Date.js, but to use them you can simply copy this
 * block of code into any script that is included after Date.js and they will also become
 * globally available on the Date object.  Feel free to add or remove patterns as needed in your code.
 * <pre><code>
Date.patterns = {
    ISO8601Long:"Y-m-d H:i:s",
    ISO8601Short:"Y-m-d",
    ShortDate: "n/j/Y",
    LongDate: "l, F d, Y",
    FullDateTime: "l, F d, Y g:i:s A",
    MonthDay: "F d",
    ShortTime: "g:i A",
    LongTime: "g:i:s A",
    SortableDateTime: "Y-m-d\\TH:i:s",
    UniversalSortableDateTime: "Y-m-d H:i:sO",
    YearMonth: "F, Y"
};
</code></pre>
 *
 * Example usage:
 * <pre><code>
var dt = new Date();
document.write(dt.format(Date.patterns.ShortDate));
 </code></pre>

/**
 * @class Roo.DomQuery
Provides high performance selector/xpath processing by compiling queries into reusable functions. New pseudo classes and matchers can be plugged. It works on HTML and XML documents (if a content node is passed in).
<p>
DomQuery supports most of the <a href="http://www.w3.org/TR/2005/WD-css3-selectors-20051215/">CSS3 selectors spec</a>, along with some custom selectors and basic XPath.</p>

<p>
All selectors, attribute filters and pseudos below can be combined infinitely in any order. For example "div.foo:nth-child(odd)[@foo=bar].bar:first" would be a perfectly valid selector. Node filters are processed in the order in which they appear, which allows you to optimize your queries for your document structure.
</p>
<h4>Element Selectors:</h4>
<ul class="list">
    <li> <b>*</b> any element</li>
    <li> <b>E</b> an element with the tag E</li>
    <li> <b>E F</b> All descendent elements of E that have the tag F</li>
    <li> <b>E > F</b> or <b>E/F</b> all direct children elements of E that have the tag F</li>
    <li> <b>E + F</b> all elements with the tag F that are immediately preceded by an element with the tag E</li>
    <li> <b>E ~ F</b> all elements with the tag F that are preceded by a sibling element with the tag E</li>
</ul>
<h4>Attribute Selectors:</h4>
<p>The use of @ and quotes are optional. For example, div[@foo='bar'] is also a valid attribute selector.</p>
<ul class="list">
    <li> <b>E[foo]</b> has an attribute "foo"</li>
    <li> <b>E[foo=bar]</b> has an attribute "foo" that equals "bar"</li>
    <li> <b>E[foo^=bar]</b> has an attribute "foo" that starts with "bar"</li>
    <li> <b>E[foo$=bar]</b> has an attribute "foo" that ends with "bar"</li>
    <li> <b>E[foo*=bar]</b> has an attribute "foo" that contains the substring "bar"</li>
    <li> <b>E[foo%=2]</b> has an attribute "foo" that is evenly divisible by 2</li>
    <li> <b>E[foo!=bar]</b> has an attribute "foo" that does not equal "bar"</li>
</ul>
<h4>Pseudo Classes:</h4>
<ul class="list">
    <li> <b>E:first-child</b> E is the first child of its parent</li>
    <li> <b>E:last-child</b> E is the last child of its parent</li>
    <li> <b>E:nth-child(<i>n</i>)</b> E is the <i>n</i>th child of its parent (1 based as per the spec)</li>
    <li> <b>E:nth-child(odd)</b> E is an odd child of its parent</li>
    <li> <b>E:nth-child(even)</b> E is an even child of its parent</li>
    <li> <b>E:only-child</b> E is the only child of its parent</li>
    <li> <b>E:checked</b> E is an element that is has a checked attribute that is true (e.g. a radio or checkbox) </li>
    <li> <b>E:first</b> the first E in the resultset</li>
    <li> <b>E:last</b> the last E in the resultset</li>
    <li> <b>E:nth(<i>n</i>)</b> the <i>n</i>th E in the resultset (1 based)</li>
    <li> <b>E:odd</b> shortcut for :nth-child(odd)</li>
    <li> <b>E:even</b> shortcut for :nth-child(even)</li>
    <li> <b>E:contains(foo)</b> E's innerHTML contains the substring "foo"</li>
    <li> <b>E:nodeValue(foo)</b> E contains a textNode with a nodeValue that equals "foo"</li>
    <li> <b>E:not(S)</b> an E element that does not match simple selector S</li>
    <li> <b>E:has(S)</b> an E element that has a descendent that matches simple selector S</li>
    <li> <b>E:next(S)</b> an E element whose next sibling matches simple selector S</li>
    <li> <b>E:prev(S)</b> an E element whose previous sibling matches simple selector S</li>
</ul>
<h4>CSS Value Selectors:</h4>
<ul class="list">
    <li> <b>E{display=none}</b> css value "display" that equals "none"</li>
    <li> <b>E{display^=none}</b> css value "display" that starts with "none"</li>
    <li> <b>E{display$=none}</b> css value "display" that ends with "none"</li>
    <li> <b>E{display*=none}</b> css value "display" that contains the substring "none"</li>
    <li> <b>E{display%=2}</b> css value "display" that is evenly divisible by 2</li>
    <li> <b>E{display!=none}</b> css value "display" that does not equal "none"</li>
</ul>

// or with a DOM element

 * Using Roo.get() or getEl() instead of calling the constructor directly ensures you get the same object
 * each call instead of constructing a new one.<br><br>
 * <b>Animations</b><br />
 * Many of the functions for manipulating an element have an optional "animate" parameter. The animate parameter
 * should either be a boolean (true) or an object literal with animation options. The animation options are:
<pre>
Option    Default   Description
--------- --------  ---------------------------------------------
duration  .35       The duration of the animation in seconds
easing    easeOut   The YUI easing method
callback  none      A function to execute when the anim completes
scope     this      The scope (this) of the callback function
</pre>
* Also, the Anim object being used for the animation will be set on your options object as "anim", which allows you to stop or
* manipulate the animation. Here's an example:
<pre><code>
var el = Roo.get("my-div");

// no animation
el.setWidth(100);

// default animation
el.setWidth(100, true);

// animation with some options set
el.setWidth(100, {
    duration: 1,
    callback: this.foo,
    scope: this
});

// using the "anim" property to get the Anim object
var opt = {
    duration: 1,
    callback: this.foo,
    scope: this
};
el.setWidth(100, opt);
...
if(opt.anim.isAnimated()){
    opt.anim.stop();
}

         * <ul>
         *   <li><b>Blank</b>: Defaults to aligning the element's top-left corner to the target's bottom-left corner ("tl-bl").</li>
         *   <li><b>One anchor (deprecated)</b>: 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.  <i>This method has been
         *       deprecated in favor of the newer two anchor syntax below</i>.</li>

         * 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:

/**
 * @class Roo.Fx
 * <p>A class to provide basic animation and visual effects support.  <b>Note:</b> This class is automatically applied
 * to the {@link Roo.Element} interface when included, so all effects calls should be performed via Element.
 * Conversely, since the effects are not actually defined in Element, Roo.Fx <b>must</b> be included in order for the 
 * Element effects to work.</p><br/>
 *
 * <p>It is important to note that although the Fx methods and many non-Fx Element methods support "method chaining" in that
 * they return the Element object itself as the method return value, it is not always possible to mix the two in a single
 * method chain.  The Fx methods use an internal effects queue so that each effect can be properly timed and sequenced.
 * Non-Fx methods, on the other hand, have no such internal queueing and will always execute immediately.  For this reason,
 * while it may be possible to mix certain Fx and non-Fx method calls in a single chain, it may not always provide the
 * expected results and should be done with care.</p><br/>
 *
 * <p>Motion effects support 8-way anchoring, meaning that you can choose one of 8 different anchor points on the Element
 * that will serve as either the start or end point of the animation.  Following are all of the supported anchor positions:</p>
<pre>
Value  Description
-----  -----------------------------
tl     The top left corner
t      The center of the top edge
tr     The top right corner
l      The center of the left edge
r      The center of the right edge
bl     The bottom left corner
b      The center of the bottom edge
br     The bottom right corner
</pre>
 * <b>Although some Fx methods accept specific custom config parameters, the ones shown in the Config Options section
 * below are common options that can be passed to any Fx method.</b>
 * @cfg {Function} callback A function called when the effect is finished
 * @cfg {Object} scope The scope of the effect function
 * @cfg {String} easing A valid Easing value for the effect
 * @cfg {String} afterCls A css class to apply after the effect
 * @cfg {Number} duration The length of time (in seconds) that the effect should last
 * @cfg {Boolean} remove Whether the Element should be removed from the DOM and destroyed after the effect finishes
 * @cfg {Boolean} useDisplay Whether to use the <i>display</i> CSS property instead of <i>visibility</i> when hiding Elements (only applies to 
 * effects that end with the element being visually hidden, ignored otherwise)
 * @cfg {String/Object/Function} afterStyle A style specification string, e.g. "width:100px", or an object in the form {width:"100px"}, or
 * a function which returns such a specification that will be applied to the Element after the effect finishes
 * @cfg {Boolean} block Whether the effect should block other effects from queueing while it runs
 * @cfg {Boolean} concurrent Whether to allow subsequently-queued effects to run at the same time as the current effect, or to ensure that they run in sequence
 * @cfg {Boolean} stopFx Whether subsequent effects should be stopped and removed after the current effect finishes

 *  then call addxtype() to build the User interface.
 * 
 * Mypart.xyx = new Roo.XComponent({

 *
 *
 * It can be used to build a big heiracy, with parent etc.
 * or you can just use this to render a single compoent to a dom element
 * MYPART.render(Roo.Element | String(id) | dom_element )
 *
 *
 * Usage patterns.
 *
 * Classic Roo
 *
 * Roo is designed primarily as a single page application, so the UI build for a standard interface will
 * expect a single 'TOP' level module normally indicated by the 'parent' of the XComponent definition being defined as false.
 *
 * Each sub module is expected to have a parent pointing to the class name of it's parent module.
 *
 * When the top level is false, a 'Roo.BorderLayout' is created and the element is flagged as 'topModule'
 * - if mulitple topModules exist, the last one is defined as the top module.
 *
 * Embeded Roo
 * 
 * When the top level or multiple modules are to embedded into a existing HTML page,
 * the parent element can container '#id' of the element where the module will be drawn.
 *
 * Bootstrap Roo
 *
 * Unlike classic Roo, the bootstrap tends not to be used as a single page.
 * it relies more on a include mechanism, where sub modules are included into an outer page.
 * This is normally managed by the builder tools using Roo.apply( options, Included.Sub.Module )
 * 
 * Bootstrap Roo Included elements
 *
 * Our builder application needs the ability to preview these sub compoennts. They will normally have parent=false set,
 * hence confusing the component builder as it thinks there are multiple top level elements. 
 *
 * String Over-ride & Translations
 *
 * Our builder application writes all the strings as _strings and _named_strings. This is to enable the translation of elements,
 * and also the 'overlaying of string values - needed when different versions of the same application with different text content
 * are needed. @see Roo.XComponent.overlayString  
 * 
 * 
 *

/**
 * @class Roo.dd.DragDrop
 * @extends Roo.util.Observable
 * Defines the interface and base operation of items that that can be
 * dragged or can be drop targets.  It was designed to be extended, overriding
 * the event handlers for startDrag, onDrag, onDragOver and onDragOut.
 * Up to three html elements can be associated with a DragDrop instance:
 * <ul>
 * <li>linked element: the element that is passed into the constructor.
 * This is the element which defines the boundaries for interaction with
 * other DragDrop objects.</li>
 * <li>handle element(s): The drag operation only occurs if the element that
 * was clicked matches a handle element.  By default this is the linked
 * element, but there are times that you will want only a portion of the
 * linked element to initiate the drag operation, and the setHandleElId()
 * method provides a way to define this.</li>
 * <li>drag element: this represents the element that would be moved along
 * with the cursor during a drag operation.  By default, this is the linked
 * element itself as in {@link Roo.dd.DD}.  setDragElId() lets you define
 * a separate element that would be moved, as in {@link Roo.dd.DDProxy}.
 * </li>
 * </ul>
 * This class should not be instantiated until the onload event to ensure that
 * the associated elements are available.
 * The following would define a DragDrop obj that would interact with any
 * other DragDrop obj in the "group1" group:
 * <pre>
 *  dd = new Roo.dd.DragDrop("div1", "group1");
 * </pre>
 * Since none of the event handlers have been implemented, nothing would
 * actually happen if you were to run the code above.  Normally you would
 * override this class or one of the default implementations, but you can
 * also override the methods you want on an instance of the class...
 * <pre>
 *  dd.onDragDrop = function(e, id) {
 *  &nbsp;&nbsp;alert("dd was dropped on " + id);
 *  }
 * </pre>
