/** * This feature allows to display the grid rows aggregated into groups as specified by the {@link Ext.data.Store#grouper grouper} * * underneath. The groups can also be expanded and collapsed. * * ## Extra Events * * This feature adds several extra events that will be fired on the grid to interact with the groups: * * - {@link #groupclick} * - {@link #groupdblclick} * - {@link #groupcontextmenu} * - {@link #groupexpand} * - {@link #groupcollapse} * * ## Menu Augmentation * * This feature adds extra options to the grid column menu to provide the user with functionality to modify the grouping. * This can be disabled by setting the {@link #enableGroupingMenu} option. The option to disallow grouping from being turned off * by the user is {@link #enableNoGroups}. * * ## Controlling Group Text * * The {@link #groupHeaderTpl} is used to control the rendered title for each group. It can modified to customized * the default display. * * ## Groupers * * By default, this feature expects that the data field that is mapped to by the * {@link Ext.data.AbstractStore#groupField} config is a simple data type such as a * String or a Boolean. However, if you intend to group by a data field that is a * complex data type such as an Object or Array, it is necessary to define one or more * {@link Ext.util.Grouper groupers} on the feature that it can then use to lookup * internal group information when grouping by different fields. * * var feature = Ext.create('Ext.grid.feature.Grouping', { * startCollapsed: true, * groupers: [{ * property: 'asset', * groupFn: function (val) { * return val.data.name; * } * }] * }); * * ## Example Usage * * @example * var store = Ext.create('Ext.data.Store', { * fields: ['name', 'seniority', 'department'], * groupField: 'department', * data: [ * { name: 'Michael Scott', seniority: 7, department: 'Management' }, * { name: 'Dwight Schrute', seniority: 2, department: 'Sales' }, * { name: 'Jim Halpert', seniority: 3, department: 'Sales' }, * { name: 'Kevin Malone', seniority: 4, department: 'Accounting' }, * { name: 'Angela Martin', seniority: 5, department: 'Accounting' } * ] * }); * * Ext.create('Ext.grid.Panel', { * title: 'Employees', * store: store, * columns: [ * { text: 'Name', dataIndex: 'name', flex: 1 }, * { text: 'Seniority', dataIndex: 'seniority', flex: 1 } * ], * features: [{ftype:'grouping'}], * renderTo: Ext.getBody() * }); * * **Note:** To use grouping with a grid that has {@link Ext.grid.column.Column#locked locked columns}, you need to supply * the grouping feature as a config object - so the grid can create two instances of the grouping feature. */Ext.define('Ext.grid.feature.Grouping', { extend: 'Ext.grid.feature.Feature', mixins: { summary: 'Ext.grid.feature.AbstractSummary' }, requires: ['Ext.grid.feature.GroupStore'], alias: 'feature.grouping', eventPrefix: 'group', eventSelector: '.' + Ext.baseCSSPrefix + 'grid-group-hd', refreshData: {}, wrapsItem: true, /** * @event groupclick * @param {Ext.view.Table} view * @param {HTMLElement} node * @param {String} group The name of the group * @param {Ext.event.Event} e */ /** * @event groupdblclick * @param {Ext.view.Table} view * @param {HTMLElement} node * @param {String} group The name of the group * @param {Ext.event.Event} e */ /** * @event groupcontextmenu * @param {Ext.view.Table} view * @param {HTMLElement} node * @param {String} group The name of the group * @param {Ext.event.Event} e */ /** * @event groupcollapse * @param {Ext.view.Table} view * @param {HTMLElement} node * @param {String} group The name of the group */ /** * @event groupexpand * @param {Ext.view.Table} view * @param {HTMLElement} node * @param {String} group The name of the group */ /** * @cfg {String/Array/Ext.Template} groupHeaderTpl * A string Template snippet, an array of strings (optionally followed by an object containing Template methods) to be used to construct a Template, or a Template instance. * * - Example 1 (Template snippet): * * groupHeaderTpl: 'Group: {name}' * * - Example 2 (Array): * * groupHeaderTpl: [ * 'Group: ', * '<div>{name:this.formatName}</div>', * { * formatName: function(name) { * return Ext.String.trim(name); * } * } * ] * * - Example 3 (Template Instance): * * groupHeaderTpl: Ext.create('Ext.XTemplate', * 'Group: ', * '<div>{name:this.formatName}</div>', * { * formatName: function(name) { * return Ext.String.trim(name); * } * } * ) * * @cfg {String} groupHeaderTpl.groupField The field name being grouped by. * @cfg {String} groupHeaderTpl.columnName The column header associated with the field being grouped by *if there is a column for the field*, falls back to the groupField name. * @cfg {Mixed} groupHeaderTpl.groupValue The value of the {@link Ext.data.Store#groupField groupField} for the group header being rendered. * @cfg {String} groupHeaderTpl.renderedGroupValue The rendered value of the {@link Ext.data.Store#groupField groupField} for the group header being rendered, as produced by the column renderer. * @cfg {String} groupHeaderTpl.name An alias for renderedGroupValue * @cfg {Ext.data.Model[]} groupHeaderTpl.rows Deprecated - use children instead.
