8 * @class Ext.grid.EditorGridPanel
9 * @extends Ext.grid.GridPanel
10 * <p>This class extends the {@link Ext.grid.GridPanel GridPanel Class} to provide cell editing
11 * on selected {@link Ext.grid.Column columns}. The editable columns are specified by providing
12 * an {@link Ext.grid.ColumnModel#editor editor} in the {@link Ext.grid.Column column configuration}.</p>
13 * <p>Editability of columns may be controlled programatically by inserting an implementation
14 * of {@link Ext.grid.ColumnModel#isCellEditable isCellEditable} into the
15 * {@link Ext.grid.ColumnModel ColumnModel}.</p>
16 * <p>Editing is performed on the value of the <i>field</i> specified by the column's
17 * <tt>{@link Ext.grid.ColumnModel#dataIndex dataIndex}</tt> in the backing {@link Ext.data.Store Store}
18 * (so if you are using a {@link Ext.grid.ColumnModel#setRenderer renderer} in order to display
19 * transformed data, this must be accounted for).</p>
20 * <p>If a value-to-description mapping is used to render a column, then a {@link Ext.form.Field#ComboBox ComboBox}
21 * which uses the same {@link Ext.form.Field#valueField value}-to-{@link Ext.form.Field#displayFieldField description}
22 * mapping would be an appropriate editor.</p>
23 * If there is a more complex mismatch between the visible data in the grid, and the editable data in
24 * the {@link Edt.data.Store Store}, then code to transform the data both before and after editing can be
25 * injected using the {@link #beforeedit} and {@link #afteredit} events.
27 * @param {Object} config The config object
30 Ext.grid.EditorGridPanel = Ext.extend(Ext.grid.GridPanel, {
32 * @cfg {Number} clicksToEdit
33 * <p>The number of clicks on a cell required to display the cell's editor (defaults to 2).</p>
34 * <p>Setting this option to 'auto' means that mousedown <i>on the selected cell</i> starts
35 * editing that cell.</p>
40 * @cfg {Boolean} forceValidation
41 * True to force validation even if the value is unmodified (defaults to false)
43 forceValidation: false,
51 * @cfg {Boolean} autoEncode
52 * True to automatically HTML encode and decode values pre and post edit (defaults to false)
57 * @cfg {Boolean} trackMouseOver @hide
60 trackMouseOver: false, // causes very odd FF errors
63 initComponent : function(){
64 Ext.grid.EditorGridPanel.superclass.initComponent.call(this);
68 * @cfg {Object} selModel Any subclass of AbstractSelectionModel that will provide the selection model for
69 * the grid (defaults to {@link Ext.grid.CellSelectionModel} if not specified).

79 * Fires before cell editing is triggered. The edit event object has the following properties <br />
80 * <ul style="padding:5px;padding-left:16px;">
81 * <li>grid - This grid</li>
82 * <li>record - The record being edited</li>
83 * <li>field - The field name being edited</li>
84 * <li>value - The value for the field being edited.</li>
85 * <li>row - The grid row index</li>
86 * <li>column - The grid column index</li>
87 * <li>cancel - Set this to true to cancel the edit or return false from your handler.</li>
89 * @param {Object} e An edit event (see above for description)
94 * Fires after a cell is edited. The edit event object has the following properties <br />
95 * <ul style="padding:5px;padding-left:16px;">
96 * <li>grid - This grid</li>
97 * <li>record - The record being edited</li>
98 * <li>field - The field name being edited</li>
99 * <li>value - The value being set</li>
100 * <li>originalValue - The original value for the field, before the edit.</li>
101 * <li>row - The grid row index</li>
102 * <li>column - The grid column index</li>
106 grid.on('afteredit', afterEdit, this );
108 function afterEdit(e) {
109 // execute an XHR to send/commit data to the server, in callback do (if successful):
113 * @param {Object} e An edit event (see above for description)
117 * @event validateedit
118 * Fires after a cell is edited, but before the value is set in the record. Return false
119 * to cancel the change. The edit event object has the following properties <br />
120 * <ul style="padding:5px;padding-left:16px;">
121 * <li>grid - This grid</li>
122 * <li>record - The record being edited</li>
123 * <li>field - The field name being edited</li>
124 * <li>value - The value being set</li>
125 * <li>originalValue - The original value for the field, before the edit.</li>
126 * <li>row - The grid row index</li>
127 * <li>column - The grid column index</li>
128 * <li>cancel - Set this to true to cancel the edit or return false from your handler.</li>
130 * Usage example showing how to remove the red triangle (dirty record indicator) from some
131 * records (not all). By observing the grid's validateedit event, it can be cancelled if
132 * the edit occurs on a targeted row (for example) and then setting the field's new value
133 * in the Record directly:
135 grid.on('validateedit', function(e) {
138 if (e.row == myTargetRow) {
140 e.record.data[e.field] = e.value;
144 * @param {Object} e An edit event (see above for description)
