/**
 * @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>

 * @class Roo.Element
 * Represents an Element in the DOM.<br><br>
 * Usage:<br>
<pre><code>
var el = Roo.get("my-div");

// or with getEl
var el = getEl("my-div");

// or with a DOM element
var el = Roo.get(myDivElement);
</code></pre>
 * 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();
}
</code></pre>
* <b> Composite (Collections of) Elements</b><br />
 * For working with collections of Elements, see <a href="Roo.CompositeElement.html">Roo.CompositeElement</a>
 * @constructor Create a new Element directly.
 * @param {String/HTMLElement} element
 * @param {Boolean} forceNew (optional) By default the constructor checks to see if there is already an instance of this element in the cache and if there is it returns the same instance. This will skip that check (useful for extending this class).

         * 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:
         * <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>
         *   <li><b>Two anchors</b>: 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.</li>
         * </ul>
         * 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:
    <pre>
    Value  Description
    -----  -----------------------------
    tl     The top left corner (default)
    t      The center of the top edge

/**
 * @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

/**
 * @class Roo.KeyMap
 * Handles mapping keys to actions for an element. One key map can be used for multiple actions.
 * The constructor accepts the same config object as defined by {@link #addBinding}.
 * If you bind a callback function to a KeyMap, anytime the KeyMap handles an expected key
 * combination it will call the function with this signature (if the match is a multi-key
 * combination the callback will still be called only once): (String key, Roo.EventObject e)
 * A KeyMap can also handle a string representation of keys.<br />
 * Usage:
 <pre><code>
// map one key by key code
var map = new Roo.KeyMap("my-element", {
    key: 13, // or Roo.EventObject.ENTER
    fn: myHandler,
    scope: myObject
});

// map multiple keys to one action by string
var map = new Roo.KeyMap("my-element", {
    key: "a\r\n\t",
    fn: myHandler,
    scope: myObject
});

// map multiple keys to multiple actions by strings and array of codes
var map = new Roo.KeyMap("my-element", [
    {
        key: [10,13],
        fn: function(){ alert("Return was pressed"); }
    }, {
        key: "abc",
        fn: function(){ alert('a, b or c was pressed'); }
    }, {
        key: "\t",
        ctrl:true,
        shift:true,
        fn: function(){ alert('Control + shift + tab was pressed.'); }
    }
]);

/**
 * @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);
 *  }

/**
 * @class Roo.Resizable
 * @extends Roo.util.Observable
 * <p>Applies drag handles to an element to make it resizable. The drag handles are inserted into the element
 * and positioned absolute. Some elements, such as a textarea or image, don't support this. To overcome that, you can wrap
 * the textarea in a div and set "resizeChild" to true (or to the id of the element), <b>or</b> set wrap:true in your config and
 * the element will be wrapped for you automatically.</p>
 * <p>Here is the list of valid resize handles:</p>
 * <pre>
Value   Description
------  -------------------
 'n'     north
 's'     south
 'e'     east
 'w'     west
 'nw'    northwest
 'sw'    southwest
 'se'    southeast
 'ne'    northeast
 'hd'    horizontal drag
 'all'   all
</pre>
 * <p>Here's an example showing the creation of a typical Resizable:</p>
 * <pre><code>
var resizer = new Roo.Resizable("element-id", {
    handles: 'all',
    minWidth: 200,
    minHeight: 100,
    maxWidth: 500,
    maxHeight: 400,
    pinned: true
});
resizer.on("resize", myHandler);
</code></pre>
 * <p>To hide a particular handle, set its display to none in CSS, or through script:<br>
 * resizer.east.setDisplayed(false);</p>
 * @cfg {Boolean/String/Element} resizeChild True to resize the first child, or id/element to resize (defaults to false)
 * @cfg {Array/String} adjustments String "auto" or an array [width, height] with values to be <b>added</b> to the
 * resize operation's new size (defaults to [0, 0])
 * @cfg {Number} minWidth The minimum width for the element (defaults to 5)
 * @cfg {Number} minHeight The minimum height for the element (defaults to 5)
 * @cfg {Number} maxWidth The maximum width for the element (defaults to 10000)
 * @cfg {Number} maxHeight The maximum height for the element (defaults to 10000)
 * @cfg {Boolean} enabled False to disable resizing (defaults to true)
 * @cfg {Boolean} wrap True to wrap an element with a div if needed (required for textareas and images, defaults to false)
 * @cfg {Number} width The width of the element in pixels (defaults to null)
 * @cfg {Number} height The height of the element in pixels (defaults to null)
 * @cfg {Boolean} animate True to animate the resize (not compatible with dynamic sizing, defaults to false)
 * @cfg {Number} duration Animation duration if animate = true (defaults to .35)
 * @cfg {Boolean} dynamic True to resize the element while dragging instead of using a proxy (defaults to false)
 * @cfg {String} handles String consisting of the resize handles to display (defaults to undefined)
 * @cfg {Boolean} multiDirectional <b>Deprecated</b>.  The old style of adding multi-direction resize handles, deprecated
 * in favor of the handles config option (defaults to false)
 * @cfg {Boolean} disableTrackOver True to disable mouse tracking. This is only applied at config time. (defaults to false)
 * @cfg {String} easing Animation easing if animate = true (defaults to 'easingOutStrong')
 * @cfg {Number} widthIncrement The increment to snap the width resize in pixels (dynamic must be true, defaults to 0)
 * @cfg {Number} heightIncrement The increment to snap the height resize in pixels (dynamic must be true, defaults to 0)
 * @cfg {Boolean} pinned True to ensure that the resize handles are always visible, false to display them only when the
 * user mouses over the resizable borders. This is only applied at config time. (defaults to false)
 * @cfg {Boolean} preserveRatio True to preserve the original ratio between height and width during resize (defaults to false)
 * @cfg {Boolean} transparent True for transparent handles. This is only applied at config time. (defaults to false)
 * @cfg {Number} minX The minimum allowed page X for the element (only used for west resizing, defaults to 0)
 * @cfg {Number} minY The minimum allowed page Y for the element (only used for north resizing, defaults to 0)
 * @cfg {Boolean} draggable Convenience to initialize drag drop (defaults to false)
 * @constructor
 * Create a new resizable component
 * @param {String/HTMLElement/Roo.Element} el The id or element to resize
 * @param {Object} config configuration options

         * <pre>
Property    Type             Description
----------  ---------------  ------------------------------------------------------------------------------------
animEl            String/Element   An id or Element from which the message box should animate as it opens and
                                   closes (defaults to undefined)
buttons           Object/Boolean   A button config object (e.g., Roo.MessageBox.OKCANCEL or {ok:'Foo',
                                   cancel:'Bar'}), or false to not show any buttons (defaults to false)
closable          Boolean          False to hide the top-right close button (defaults to true).  Note that
                                   progress and wait dialogs will ignore this property and always hide the
                                   close button as they can only be closed programmatically.
cls               String           A custom CSS class to apply to the message box element
defaultTextHeight Number           The default height in pixels of the message box's multiline textarea if
                                   displayed (defaults to 75)
fn                Function         A callback function to execute after closing the dialog.  The arguments to the
                                   function will be btn (the name of the button that was clicked, if applicable,
                                   e.g. "ok"), and text (the value of the active text field, if applicable).
                                   Progress and wait dialogs will ignore this option since they do not respond to
                                   user actions and can only be closed programmatically, so any required function
                                   should be called by the same code after it closes the dialog.
icon              String           A CSS class that provides a background image to be used as an icon for
                                   the dialog (e.g., Roo.MessageBox.WARNING or 'custom-class', defaults to '')
maxWidth          Number           The maximum width in pixels of the message box (defaults to 600)
minWidth          Number           The minimum width in pixels of the message box (defaults to 100)
modal             Boolean          False to allow user interaction with the page while the message box is
                                   displayed (defaults to true)
msg               String           A string that will replace the existing message box body text (defaults
                                   to the XHTML-compliant non-breaking space character '&#160;')
multiline         Boolean          True to prompt the user to enter multi-line text (defaults to false)
progress          Boolean          True to display a progress bar (defaults to false)
progressText      String           The text to display inside the progress bar if progress = true (defaults to '')
prompt            Boolean          True to prompt the user to enter single-line text (defaults to false)
proxyDrag         Boolean          True to display a lightweight proxy while dragging (defaults to false)
title             String           The title text
value             String           The string value to set into the active textbox element if displayed
wait              Boolean          True to display a progress bar (defaults to false)
width             Number           The width of the dialog in pixels

 * who's elements are node definition objects. eg:
 * <pre><code>

    { 'id': 1, 'text': 'A folder Node', 'leaf': false },

 * <br><br>
 * The old style respose with just an array is still supported, but not recommended.
 * <br><br>
 *
 * A server request is sent, and child nodes are loaded only when a node is expanded.
 * The loading node's id is passed to the server under the parameter name "node" to
 * enable the server to produce the correct child nodes.
 * <br><br>
 * To pass extra parameters, an event handler may be attached to the "beforeload"
 * event, and the parameters specified in the TreeLoader's baseParams property:
 * <pre><code>
    myTreeLoader.on("beforeload", function(treeLoader, node) {
        this.baseParams.category = node.attributes.category;

/**
 * @class Roo.form.TriggerField
 * @extends Roo.form.TextField
 * Provides a convenient wrapper for TextFields that adds a clickable trigger button (looks like a combobox by default).
 * The trigger has no default action, so you must assign a function to implement the trigger click handler by
 * overriding {@link #onTriggerClick}. You can create a TriggerField directly, as it renders exactly like a combobox
 * for which you can provide a custom implementation.  For example:
 * <pre><code>
var trigger = new Roo.form.TriggerField();
trigger.onTriggerClick = myTriggerFn;
trigger.applyTo('my-field');
</code></pre>
 *
 * However, in general you will most likely want to use TriggerField as the base class for a reusable component.
 * {@link Roo.form.DateField} and {@link Roo.form.ComboBox} are perfect examples of this.
 * @cfg {String} triggerClass An additional CSS class used to style the trigger button.  The trigger will always get the
 * class 'x-form-trigger' by default and triggerClass will be <b>appended</b> if specified.
 * @constructor
 * Create a new TriggerField.
 * @param {Object} config Configuration options (valid {@Roo.form.TextField} config options will also be applied
 * to the base TextField)

 * This is a pre-built layout that represents a classic, 5-pane application.  It consists of a header, a primary
 * center region containing two nested regions (a top one for a list view and one for item preview below),
 * and regions on either side that can be used for navigation, application commands, informational displays, etc.
 * The setup and configuration work exactly the same as it does for a {@link Roo.BorderLayout} - this class simply
 * expedites the setup of the overall layout and regions for this common application style.
 * Example:
 <pre><code>
var reader = new Roo.ReaderLayout();
var CP = Roo.ContentPanel;  // shortcut for adding

reader.beginUpdate();
reader.add("north", new CP("north", "North"));
reader.add("west", new CP("west", {title: "West"}));
reader.add("east", new CP("east", {title: "East"}));

reader.regions.listView.add(new CP("listView", "List"));
reader.regions.preview.add(new CP("preview", "Preview"));
reader.endUpdate();
</code></pre>
* @constructor
* Create a new ReaderLayout
* @param {Object} config Configuration options
* @param {String/HTMLElement/Element} container (optional) The container this layout is bound to (defaults to
* document.body if omitted)

/**
 * @class Roo.grid.Grid
 * @extends Roo.util.Observable
 * This class represents the primary interface of a component based grid control.
 * <br><br>Usage:<pre><code>
 var grid = new Roo.grid.Grid("my-container-id", {
     ds: myDataStore,
     cm: myColModel,
     selModel: mySelectionModel,
     autoSizeColumns: true,
     monitorWindowResize: false,
     trackMouseOver: true
 });
 // set any options
 grid.render();
 * </code></pre>
 * <b>Common Problems:</b><br/>
 * - Grid does not resize properly when going smaller: Setting overflow hidden on the container
 * element will correct this<br/>
 * - If you get el.style[camel]= NaNpx or -2px or something related, be certain you have given your container element
 * dimensions. The grid adapts to your container's size, if your container has no size defined then the results
 * are unpredictable.<br/>
 * - Do not render the grid into an element with display:none. Try using visibility:hidden. Otherwise there is no way for the
 * grid to calculate dimensions/offsets.<br/>
  * @constructor
 * @param {String/HTMLElement/Roo.Element} container The element into which this grid will be rendered -
 * The container MUST have some type of size defined for the grid to fill. The container will be
 * automatically set to position relative if it isn't already.
 * @param {Object} config A config object that sets properties on this grid.
