/** * The Ext.grid.plugin.CellEditing plugin injects editing at a cell level for a Grid. Only a single * cell will be editable at a time. The field that will be used for the editor is defined at the * {@link Ext.grid.column.Column#editor editor}. The editor can be a field instance or a field configuration. * * If an editor is not specified for a particular column then that cell will not be editable and it will * be skipped when activated via the mouse or the keyboard. * * The editor may be shared for each column in the grid, or a different one may be specified for each column. * An appropriate field type should be chosen to match the data structure that it will be editing. For example, * to edit a date, it would be useful to specify {@link Ext.form.field.Date} as the editor. * * If the `editor` config on a column contains a `field` property, then the `editor` config is used to create * the wrapping {@link Ext.grid.CellEditorCellEditor}, and the `field` property is used to create the editing * input field. * * ## Example * * A grid with editor for the name and the email columns: * * @example * Ext.create('Ext.data.Store', { * storeId: 'simpsonsStore', * 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: Ext.data.StoreManager.lookup('simpsonsStore'), * columns: [ * {header: 'Name', dataIndex: 'name', editor: 'textfield'}, * {header: 'Email', dataIndex: 'email', flex:1, * editor: { * completeOnEnter: false, * * // If the editor config contains a field property, then * // the editor config is used to create the {@link Ext.grid.CellEditor CellEditor} * // and the field property is used to create the editing input field. * field: { * xtype: 'textfield', * allowBlank: false * } * } * }, * {header: 'Phone', dataIndex: 'phone'} * ], * selModel: 'cellmodel', * plugins: { * ptype: 'cellediting', * clicksToEdit: 1 * }, * height: 200, * width: 400, * renderTo: Ext.getBody() * }); * * This requires a little explanation. We're passing in `store` and `columns` as normal, but * we also specify a {@link Ext.grid.column.Column#field field} on two of our columns. For the * Name column we just want a default textfield to edit the value, so we specify 'textfield'. * For the Email column we customized the editor slightly by passing allowBlank: false, which * will provide inline validation. * * To support cell editing, we also specified that the grid should use the 'cellmodel' * {@link Ext.grid.Panel#selModel selModel}, and created an instance of the CellEditing plugin, * which we configured to activate each editor after a single click. * */Ext.define('Ext.grid.plugin.CellEditing', { alias: 'plugin.cellediting', extend: 'Ext.grid.plugin.Editing', requires: ['Ext.grid.CellEditor', 'Ext.util.DelayedTask'], /** * @event beforeedit * Fires before cell editing is triggered.
