/** * @class Ext.grid.EditorGridPanel * @extends Ext.grid.GridPanel *

This class extends the {@link Ext.grid.GridPanel GridPanel Class} to provide cell editing * on selected {@link Ext.grid.Column columns}. The editable columns are specified by providing * an {@link Ext.grid.ColumnModel#editor editor} in the {@link Ext.grid.Column column configuration}.

*

Editability of columns may be controlled programatically by inserting an implementation * of {@link Ext.grid.ColumnModel#isCellEditable isCellEditable} into the * {@link Ext.grid.ColumnModel ColumnModel}.

*

Editing is performed on the value of the field specified by the column's * {@link Ext.grid.ColumnModel#dataIndex dataIndex} in the backing {@link Ext.data.Store Store} * (so if you are using a {@link Ext.grid.ColumnModel#setRenderer renderer} in order to display * transformed data, this must be accounted for).

*

If a value-to-description mapping is used to render a column, then a {@link Ext.form.Field#ComboBox ComboBox} * which uses the same {@link Ext.form.Field#valueField value}-to-{@link Ext.form.Field#displayFieldField description} * mapping would be an appropriate editor.

* If there is a more complex mismatch between the visible data in the grid, and the editable data in * the {@link Edt.data.Store Store}, then code to transform the data both before and after editing can be * injected using the {@link #beforeedit} and {@link #afteredit} events. * @constructor * @param {Object} config The config object * @xtype editorgrid */ Ext.grid.EditorGridPanel = Ext.extend(Ext.grid.GridPanel, {
