- * @class Ext.layout.ColumnLayout\r
- * @extends Ext.layout.ContainerLayout\r
- * <p>This is the layout style of choice for creating structural layouts in a multi-column format where the width of\r
- * each column can be specified as a percentage or fixed width, but the height is allowed to vary based on the content.\r
- * This class is intended to be extended or created via the layout:'column' {@link Ext.Container#layout} config,\r
- * and should generally not need to be created directly via the new keyword.</p>\r
- * <p>ColumnLayout does not have any direct config options (other than inherited ones), but it does support a\r
- * specific config property of <b><tt>columnWidth</tt></b> that can be included in the config of any panel added to it. The\r
- * layout will use the columnWidth (if present) or width of each panel during layout to determine how to size each panel.\r
- * If width or columnWidth is not specified for a given panel, its width will default to the panel's width (or auto).</p>\r
- * <p>The width property is always evaluated as pixels, and must be a number greater than or equal to 1.\r
- * The columnWidth property is always evaluated as a percentage, and must be a decimal value greater than 0 and\r
- * less than 1 (e.g., .25).</p>\r
- * <p>The basic rules for specifying column widths are pretty simple. The logic makes two passes through the\r
- * set of contained panels. During the first layout pass, all panels that either have a fixed width or none\r
- * specified (auto) are skipped, but their widths are subtracted from the overall container width. During the second\r
- * pass, all panels with columnWidths are assigned pixel widths in proportion to their percentages based on\r
- * the total <b>remaining</b> container width. In other words, percentage width panels are designed to fill the space\r
- * left over by all the fixed-width and/or auto-width panels. Because of this, while you can specify any number of columns\r
- * with different percentages, the columnWidths must always add up to 1 (or 100%) when added together, otherwise your\r
- * layout may not render as expected. Example usage:</p>\r
- * <pre><code>\r
-// All columns are percentages -- they must add up to 1\r
-var p = new Ext.Panel({\r
- title: 'Column Layout - Percentage Only',\r
- layout:'column',\r
- items: [{\r
- title: 'Column 1',\r
- columnWidth: .25\r
- },{\r
- title: 'Column 2',\r
- columnWidth: .6\r
- },{\r
- title: 'Column 3',\r
- columnWidth: .15\r
- }]\r
-});\r
-\r
-// Mix of width and columnWidth -- all columnWidth values must add up\r
-// to 1. The first column will take up exactly 120px, and the last two\r
-// columns will fill the remaining container width.\r
-var p = new Ext.Panel({\r
- title: 'Column Layout - Mixed',\r
- layout:'column',\r
- items: [{\r
- title: 'Column 1',\r
- width: 120\r
- },{\r
- title: 'Column 2',\r
- columnWidth: .8\r
- },{\r
- title: 'Column 3',\r
- columnWidth: .2\r
- }]\r
-});\r
