/** * @class Ext.grid.Column *

This class encapsulates column configuration data to be used in the initialization of a * {@link Ext.grid.ColumnModel ColumnModel}.

*

While subclasses are provided to render data in different ways, this class renders a passed * data field unchanged and is usually used for textual columns.

*/ Ext.grid.Column = Ext.extend(Ext.util.Observable, {
/** * @cfg {Boolean} editable Optional. Defaults to true, enabling the configured * {@link #editor}. Set to false to initially disable editing on this column. * The initial configuration may be dynamically altered using * {@link Ext.grid.ColumnModel}.{@link Ext.grid.ColumnModel#setEditable setEditable()}. */
/** * @cfg {String} id Optional. A name which identifies this column (defaults to the column's initial * ordinal position.) The id is used to create a CSS class name which is applied to all * table cells (including headers) in that column (in this context the id does not need to be * unique). The class name takes the form of
x-grid3-td-id
* Header cells will also receive this class name, but will also have the class
x-grid3-hd
* So, to target header cells, use CSS selectors such as:
.x-grid3-hd-row .x-grid3-td-id
* The {@link Ext.grid.GridPanel#autoExpandColumn} grid config option references the column via this * unique identifier. */
/** * @cfg {String} header Optional. The header text to be used as innerHTML * (html tags are accepted) to display in the Grid view. Note: to * have a clickable header with no text displayed use ' '. */
/** * @cfg {Boolean} groupable Optional. If the grid is being rendered by an {@link Ext.grid.GroupingView}, this option * may be used to disable the header menu item to group by the column selected. Defaults to true, * which enables the header menu group option. Set to false to disable (but still show) the * group option in the header menu for the column. See also {@link #groupName}. */
/** * @cfg {String} groupName Optional. If the grid is being rendered by an {@link Ext.grid.GroupingView}, this option * may be used to specify the text with which to prefix the group field value in the group header line. * See also {@link #groupRenderer} and * {@link Ext.grid.GroupingView}.{@link Ext.grid.GroupingView#showGroupName showGroupName}. */
/** * @cfg {Function} groupRenderer

Optional. If the grid is being rendered by an {@link Ext.grid.GroupingView}, this option * may be used to specify the function used to format the grouping field value for display in the group * {@link #groupName header}. If a groupRenderer is not specified, the configured * {@link #renderer} will be called; if a {@link #renderer} is also not specified * the new value of the group field will be used.

*

The called function (either the groupRenderer or {@link #renderer}) will be * passed the following parameters: *

*

The function should return a string value.

*/
/** * @cfg {String} emptyGroupText Optional. If the grid is being rendered by an {@link Ext.grid.GroupingView}, this option * may be used to specify the text to display when there is an empty group value. Defaults to the * {@link Ext.grid.GroupingView}.{@link Ext.grid.GroupingView#emptyGroupText emptyGroupText}. */
/** * @cfg {String} dataIndex

Required. The name of the field in the * grid's {@link Ext.data.Store}'s {@link Ext.data.Record} definition from * which to draw the column's value.

*/
/** * @cfg {Number} width * Optional. The initial width in pixels of the column. * The width of each column can also be affected if any of the following are configured: *
