---|
| 18 | * @class Ext.ux.layout.CenterLayout |
---|
| 19 | * @extends Ext.layout.FitLayout |
---|
| 20 | * <p>This is a very simple layout style used to center contents within a container. This layout works within |
---|
| 21 | * nested containers and can also be used as expected as a Viewport layout to center the page layout.</p> |
---|
| 22 | * <p>As a subclass of FitLayout, CenterLayout expects to have a single child panel of the container that uses |
---|
| 23 | * the layout. The layout does not require any config options, although the child panel contained within the |
---|
| 24 | * layout must provide a fixed or percentage width. The child panel's height will fit to the container by |
---|
| 25 | * default, but you can specify <tt>autoHeight:true</tt> to allow it to autosize based on its content height. |
---|
| 26 | * Example usage:</p> |
---|
| 27 | * <pre><code> |
---|
| 28 | // The content panel is centered in the container |
---|
| 29 | var p = new Ext.Panel({ |
---|
| 30 | title: 'Center Layout', |
---|
| 31 | layout: 'ux.center', |
---|
| 32 | items: [{ |
---|
| 33 | title: 'Centered Content', |
---|
| 34 | width: '75%', |
---|
| 35 | html: 'Some content' |
---|
| 36 | }] |
---|
| 37 | }); |
---|
| 38 | |
---|
| 39 | // If you leave the title blank and specify no border |
---|
| 40 | // you'll create a non-visual, structural panel just |
---|
| 41 | // for centering the contents in the main container. |
---|
| 42 | var p = new Ext.Panel({ |
---|
| 43 | layout: 'ux.center', |
---|
| 44 | border: false, |
---|
| 45 | items: [{ |
---|
| 46 | title: 'Centered Content', |
---|
| 47 | width: 300, |
---|
| 48 | autoHeight: true, |
---|
| 49 | html: 'Some content' |
---|
| 50 | }] |

---|
| 95 | /** |
---|
| 96 | * @class Ext.ux.layout.RowLayout |
---|
| 97 | * @extends Ext.layout.ContainerLayout |
---|
| 98 | * <p>This is the layout style of choice for creating structural layouts in a multi-row format where the height of |
---|
| 99 | * each row can be specified as a percentage or fixed height. Row widths can also be fixed, percentage or auto. |
---|
| 100 | * This class is intended to be extended or created via the layout:'ux.row' {@link Ext.Container#layout} config, |
---|
| 101 | * and should generally not need to be created directly via the new keyword.</p> |
---|
| 102 | * <p>RowLayout does not have any direct config options (other than inherited ones), but it does support a |
---|
| 103 | * specific config property of <b><tt>rowHeight</tt></b> that can be included in the config of any panel added to it. The |
---|
| 104 | * layout will use the rowHeight (if present) or height of each panel during layout to determine how to size each panel. |
---|
| 105 | * If height or rowHeight is not specified for a given panel, its height will default to the panel's height (or auto).</p> |
---|
| 106 | * <p>The height property is always evaluated as pixels, and must be a number greater than or equal to 1. |
---|
| 107 | * The rowHeight property is always evaluated as a percentage, and must be a decimal value greater than 0 and |
---|
| 108 | * less than 1 (e.g., .25).</p> |
---|
| 109 | * <p>The basic rules for specifying row heights are pretty simple. The logic makes two passes through the |
---|
| 110 | * set of contained panels. During the first layout pass, all panels that either have a fixed height or none |
---|
| 111 | * specified (auto) are skipped, but their heights are subtracted from the overall container height. During the second |
---|
| 112 | * pass, all panels with rowHeights are assigned pixel heights in proportion to their percentages based on |
---|
| 113 | * the total <b>remaining</b> container height. In other words, percentage height panels are designed to fill the space |
---|
| 114 | * left over by all the fixed-height and/or auto-height panels. Because of this, while you can specify any number of rows |
---|
| 115 | * with different percentages, the rowHeights must always add up to 1 (or 100%) when added together, otherwise your |
---|
| 116 | * layout may not render as expected. Example usage:</p> |
---|
| 117 | * <pre><code> |
---|
| 118 | // All rows are percentages -- they must add up to 1 |
---|
| 119 | var p = new Ext.Panel({ |
---|
| 120 | title: 'Row Layout - Percentage Only', |

---|
| 133 | |
---|
| 134 | // Mix of height and rowHeight -- all rowHeight values must add |
---|
| 135 | // up to 1. The first row will take up exactly 120px, and the last two |
---|
| 136 | // rows will fill the remaining container height. |
