- <pre class="prettyprint lang-js">// We are adding these custom layouts to a namespace that does not
-// exist by default in Ext, so we have to add the namespace first:
-Ext.ns('Ext.ux.layout');
-
-<div id="cls-Ext.ux.layout.RowLayout"></div>/**
- * @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
- }]
-});
-</code></pre>
