- * @class Ext.grid.EditorGridPanel
- * @extends Ext.grid.GridPanel
- * <p>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}.</p>
- * <p>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}.</p>
- * <p>Editing is performed on the value of the <i>field</i> specified by the column's
- * <tt>{@link Ext.grid.ColumnModel#dataIndex dataIndex}</tt> 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).</p>
- * <p>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.</p>
- * 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.
