 * @class Ext.ux.layout.CenterLayout
 * @extends Ext.layout.FitLayout
 * <p>This is a very simple layout style used to center contents within a container.  This layout works within
 * nested containers and can also be used as expected as a Viewport layout to center the page layout.</p>
 * <p>As a subclass of FitLayout, CenterLayout expects to have a single child panel of the container that uses
 * the layout.  The layout does not require any config options, although the child panel contained within the
 * layout must provide a fixed or percentage width.  The child panel's height will fit to the container by
 * default, but you can specify <tt>autoHeight:true</tt> to allow it to autosize based on its content height.
 * Example usage:</p>
 * <pre><code>
// The content panel is centered in the container
var p = new Ext.Panel({
    title: 'Center Layout',
    layout: 'ux.center',
    items: [{
        title: 'Centered Content',
        width: '75%',
        html: 'Some content'
    }]
});

// If you leave the title blank and specify no border
// you'll create a non-visual, structural panel just
// for centering the contents in the main container.
var p = new Ext.Panel({
    layout: 'ux.center',
    border: false,
    items: [{
        title: 'Centered Content',

/**
 * @class Ext.ux.grid.GridFilters
 * @extends Ext.util.Observable
 * <p>GridFilter is a plugin (<code>ptype='gridfilters'</code>) for grids that
 * allow for a slightly more robust representation of filtering than what is
 * provided by the default store.</p>
 * <p>Filtering is adjusted by the user using the grid's column header menu
 * (this menu can be disabled through configuration). Through this menu users
 * can configure, enable, and disable filters for each column.</p>
 * <p><b><u>Features:</u></b></p>
 * <div class="mdetail-params"><ul>
 * <li><b>Filtering implementations</b> :
 * <div class="sub-desc">
 * Default filtering for Strings, Numeric Ranges, Date Ranges, Lists (which can
 * be backed by a Ext.data.Store), and Boolean. Additional custom filter types
 * and menus are easily created by extending Ext.ux.grid.filter.Filter.
 * </div></li>
 * <li><b>Graphical indicators</b> :
 * <div class="sub-desc">
 * Columns that are filtered have {@link #filterCls a configurable css class}
 * applied to the column headers.
 * </div></li>
 * <li><b>Paging</b> :
 * <div class="sub-desc">
 * If specified as a plugin to the grid's configured PagingToolbar, the current page
 * will be reset to page 1 whenever you update the filters.
 * </div></li>
 * <li><b>Automatic Reconfiguration</b> :
 * <div class="sub-desc">
 * Filters automatically reconfigure when the grid 'reconfigure' event fires.
 * </div></li>
 * <li><b>Stateful</b> :
 * Filter information will be persisted across page loads by specifying a
 * <code>stateId</code> in the Grid configuration.
 * <div class="sub-desc">
 * The filter collection binds to the
 * <code>{@link Ext.grid.GridPanel#beforestaterestore beforestaterestore}</code>
 * and <code>{@link Ext.grid.GridPanel#beforestatesave beforestatesave}</code>
 * events in order to be stateful.
 * </div></li>
 * <li><b>Grid Changes</b> :
 * <div class="sub-desc"><ul>
 * <li>A <code>filters</code> <i>property</i> is added to the grid pointing to
 * this plugin.</li>
 * <li>A <code>filterupdate</code> <i>event</i> is added to the grid and is
 * fired upon onStateChange completion.</li>
 * </ul></div></li>

/**
 * @class Ext.ux.layout.RowLayout
 * @extends Ext.layout.ContainerLayout
 * <p>This is the layout style of choice for creating structural layouts in a multi-row format where the height of
 * each row can be specified as a percentage or fixed height.  Row widths can also be fixed, percentage or auto.
 * This class is intended to be extended or created via the layout:'ux.row' {@link Ext.Container#layout} config,
 * and should generally not need to be created directly via the new keyword.</p>
 * <p>RowLayout does not have any direct config options (other than inherited ones), but it does support a
 * specific config property of <b><tt>rowHeight</tt></b> that can be included in the config of any panel added to it.  The
 * layout will use the rowHeight (if present) or height of each panel during layout to determine how to size each panel.
 * If height or rowHeight is not specified for a given panel, its height will default to the panel's height (or auto).</p>
 * <p>The height property is always evaluated as pixels, and must be a number greater than or equal to 1.
 * The rowHeight property is always evaluated as a percentage, and must be a decimal value greater than 0 and
 * less than 1 (e.g., .25).</p>
 * <p>The basic rules for specifying row heights are pretty simple.  The logic makes two passes through the
 * set of contained panels.  During the first layout pass, all panels that either have a fixed height or none
 * specified (auto) are skipped, but their heights are subtracted from the overall container height.  During the second
 * pass, all panels with rowHeights are assigned pixel heights in proportion to their percentages based on
 * the total <b>remaining</b> container height.  In other words, percentage height panels are designed to fill the space
 * left over by all the fixed-height and/or auto-height panels.  Because of this, while you can specify any number of rows
 * with different percentages, the rowHeights must always add up to 1 (or 100%) when added together, otherwise your
 * layout may not render as expected.  Example usage:</p>
 * <pre><code>
// All rows are percentages -- they must add up to 1
var p = new Ext.Panel({
    title: 'Row Layout - Percentage Only',
    layout:'ux.row',
    items: [{
        title: 'Row 1',
        rowHeight: .25
    },{
        title: 'Row 2',
        rowHeight: .6
    },{
        title: 'Row 3',
        rowHeight: .15
    }]
});

// Mix of height and rowHeight -- all rowHeight values must add
// up to 1. The first row will take up exactly 120px, and the last two
// rows will fill the remaining container height.
var p = new Ext.Panel({
    title: 'Row Layout - Mixed',
    layout:'ux.row',
    items: [{
        title: 'Row 1',
        height: 120,
        // standard panel widths are still supported too:
        width: '50%' // or 200
    },{
        title: 'Row 2',
        rowHeight: .8,
        width: 300
    },{
        title: 'Row 3',
        rowHeight: .2
    }]
