-</span> * @class Ext.grid.column.Column
- * @extends Ext.grid.header.Container
+ <pre class="prettyprint lang-js"><span id='Ext-layout-container-Column'>/**
+</span> * This is the layout style of choice for creating structural layouts in a multi-column format where the width of each
+ * column can be specified as a percentage or fixed width, but the height is allowed to vary based on the content. This
+ * class is intended to be extended or created via the layout:'column' {@link Ext.container.Container#layout} config,
+ * and should generally not need to be created directly via the new keyword.
*
- * This class specifies the definition for a column inside a {@link Ext.grid.Panel}. It encompasses
- * both the grid header configuration as well as displaying data within the grid itself. If the
- * {@link #columns} configuration is specified, this column will become a column group and can
- * container other columns inside. In general, this class will not be created directly, rather
- * an array of column configurations will be passed to the grid:
+ * ColumnLayout does not have any direct config options (other than inherited ones), but it does support a specific
+ * config property of `columnWidth` that can be included in the config of any panel added to it. The layout will use
+ * the columnWidth (if present) or width of each panel during layout to determine how to size each panel. If width or
+ * columnWidth is not specified for a given panel, its width will default to the panel's width (or auto).
*
- * {@img Ext.grid.column.Column/Ext.grid.column.Column.png Ext.grid.column.Column grid column}
+ * The width property is always evaluated as pixels, and must be a number greater than or equal to 1. The columnWidth
+ * property is always evaluated as a percentage, and must be a decimal value greater than 0 and less than 1 (e.g., .25).
*
- * ## Code
+ * The basic rules for specifying column widths 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 width or none specified (auto)
+ * are skipped, but their widths are subtracted from the overall container width.
*
- * Ext.create('Ext.data.Store', {
- * storeId:'employeeStore',
- * fields:['firstname', 'lastname', 'senority', 'dep', 'hired'],
- * data:[
- * {firstname:"Michael", lastname:"Scott", senority:7, dep:"Manangement", hired:"01/10/2004"},
- * {firstname:"Dwight", lastname:"Schrute", senority:2, dep:"Sales", hired:"04/01/2004"},
- * {firstname:"Jim", lastname:"Halpert", senority:3, dep:"Sales", hired:"02/22/2006"},
- * {firstname:"Kevin", lastname:"Malone", senority:4, dep:"Accounting", hired:"06/10/2007"},
- * {firstname:"Angela", lastname:"Martin", senority:5, dep:"Accounting", hired:"10/21/2008"}
- * ]
- * });
+ * During the second pass, all panels with columnWidths are assigned pixel widths in proportion to their percentages
+ * based on the total **remaining** container width. In other words, percentage width panels are designed to fill
+ * the space left over by all the fixed-width and/or auto-width panels. Because of this, while you can specify any
+ * number of columns with different percentages, the columnWidths must always add up to 1 (or 100%) when added
+ * together, otherwise your layout may not render as expected.
*
- * Ext.create('Ext.grid.Panel', {
- * title: 'Column Demo',
- * store: Ext.data.StoreManager.lookup('employeeStore'),
- * columns: [
- * {text: 'First Name', dataIndex:'firstname'},
- * {text: 'Last Name', dataIndex:'lastname'},
- * {text: 'Hired Month', dataIndex:'hired', xtype:'datecolumn', format:'M'},
- * {text: 'Deparment (Yrs)', xtype:'templatecolumn', tpl:'{dep} ({senority})'}
- * ],
- * width: 400,
+ * @example
+ * // All columns are percentages -- they must add up to 1
+ * Ext.create('Ext.panel.Panel', {
+ * title: 'Column Layout - Percentage Only',
+ * width: 350,
+ * height: 250,
+ * layout:'column',
+ * items: [{
+ * title: 'Column 1',
+ * columnWidth: .25
+ * },{
+ * title: 'Column 2',
+ * columnWidth: .55
+ * },{
+ * title: 'Column 3',
+ * columnWidth: .20
+ * }],
* renderTo: Ext.getBody()
* });
*
- * ## Convenience Subclasses
- * There are several column subclasses that provide default rendering for various data types
- *
- * - {@link Ext.grid.column.Action}: Renders icons that can respond to click events inline
- * - {@link Ext.grid.column.Boolean}: Renders for boolean values
- * - {@link Ext.grid.column.Date}: Renders for date values
- * - {@link Ext.grid.column.Number}: Renders for numeric values
- * - {@link Ext.grid.column.Template}: Renders a value using an {@link Ext.XTemplate} using the record data
- *
- * ## Setting Sizes
- * The columns are laid out by a {@link Ext.layout.container.HBox} layout, so a column can either
- * be given an explicit width value or a flex configuration. If no width is specified the grid will
- * automatically the size the column to 100px. For column groups, the size is calculated by measuring
- * the width of the child columns, so a width option should not be specified in that case.
+ * // Mix of width and columnWidth -- all columnWidth values must add up
+ * // to 1. The first column will take up exactly 120px, and the last two
+ * // columns will fill the remaining container width.
*
- * ## Header Options
- * - {@link #text}: Sets the header text for the column
- * - {@link #sortable}: Specifies whether the column can be sorted by clicking the header or using the column menu
- * - {@link #hideable}: Specifies whether the column can be hidden using the column menu
- * - {@link #menuDisabled}: Disables the column header menu
- * - {@link #draggable}: Specifies whether the column header can be reordered by dragging
- * - {@link #groupable}: Specifies whether the grid can be grouped by the column dataIndex. See also {@link Ext.grid.feature.Grouping}
- *
- * ## Data Options
- * - {@link #dataIndex}: The dataIndex is the field in the underlying {@link Ext.data.Store} to use as the value for the column.
- * - {@link #renderer}: Allows the underlying store value to be transformed before being displayed in the grid
+ * Ext.create('Ext.Panel', {
+ * title: 'Column Layout - Mixed',
+ * width: 350,
+ * height: 250,
+ * layout:'column',
+ * items: [{
+ * title: 'Column 1',
+ * width: 120
+ * },{
+ * title: 'Column 2',
+ * columnWidth: .7
+ * },{
+ * title: 'Column 3',
+ * columnWidth: .3
+ * }],
+ * renderTo: Ext.getBody()
+ * });
