/** * RowModel Selection Model implements row based navigation for * {@link Ext.grid.Panel grid panels} via user input. RowModel is the default grid selection * model and, generally, will not need to be specified. * * By utilizing the selModel config as an object, you may also set configurations for: * * + {@link #mode} - Specifies whether user may select multiple rows or single rows * + {@link #allowDeselect} - Specifies whether user may deselect records when in SINGLE mode * + {@link #ignoreRightMouseSelection} - Specifies whether user may ignore right clicks * for selection purposes * * In the example below, we've enabled MULTI mode. This means that multiple rows can be selected. * * @example * var store = Ext.create('Ext.data.Store', { * fields: ['name', 'email', 'phone'], * data: [ * { name: 'Lisa', email: '[email protected]', phone: '555-111-1224' }, * { name: 'Bart', email: '[email protected]', phone: '555-222-1234' }, * { name: 'Homer', email: '[email protected]', phone: '555-222-1244' }, * { name: 'Marge', email: '[email protected]', phone: '555-222-1254' } * ] * }); * * Ext.create('Ext.grid.Panel', { * title: 'Simpsons', * store: store, * width: 400, * renderTo: Ext.getBody(), * selModel: { * selType: 'rowmodel', // rowmodel is the default selection model * mode: 'MULTI' // Allows selection of multiple rows * }, * columns: [ * { text: 'Name', dataIndex: 'name' }, * { text: 'Email', dataIndex: 'email', flex: 1 }, * { text: 'Phone', dataIndex: 'phone' } * ] * }); */Ext.define('Ext.selection.RowModel', { extend: 'Ext.selection.DataViewModel', alias: 'selection.rowmodel', requires: [ 'Ext.grid.CellContext' ], /** * @cfg {Boolean} enableKeyNav * * Turns on/off keyboard navigation within the grid. */ enableKeyNav: true, /** * @event beforedeselect * Fired before a record is deselected.
