- * @class Ext.dd.DragZone\r
- * @extends Ext.dd.DragSource\r
- * <p>This class provides a container DD instance that allows dragging of multiple child source nodes.</p>\r
- * <p>This class does not move the drag target nodes, but a proxy element which may contain\r
- * any DOM structure you wish. The DOM element to show in the proxy is provided by either a\r
- * provided implementation of {@link #getDragData}, or by registered draggables registered with {@link Ext.dd.Registry}</p>\r
- * <p>If you wish to provide draggability for an arbitrary number of DOM nodes, each of which represent some\r
- * application object (For example nodes in a {@link Ext.DataView DataView}) then use of this class\r
- * is the most efficient way to "activate" those nodes.</p>\r
- * <p>By default, this class requires that draggable child nodes are registered with {@link Ext.dd.Registry}.\r
- * However a simpler way to allow a DragZone to manage any number of draggable elements is to configure\r
- * the DragZone with an implementation of the {@link #getDragData} method which interrogates the passed\r
- * mouse event to see if it has taken place within an element, or class of elements. This is easily done\r
- * by using the event's {@link Ext.EventObject#getTarget getTarget} method to identify a node based on a\r
- * {@link Ext.DomQuery} selector. For example, to make the nodes of a DataView draggable, use the following\r
- * technique. Knowledge of the use of the DataView is required:</p><pre><code>\r
-myDataView.on('render', function(v) {\r
- myDataView.dragZone = new Ext.dd.DragZone(v.getEl(), {\r
-\r
-// On receipt of a mousedown event, see if it is within a DataView node.\r
-// Return a drag data object if so.\r
- getDragData: function(e) {\r
-\r
-// Use the DataView's own itemSelector (a mandatory property) to\r
-// test if the mousedown is within one of the DataView's nodes.\r
- var sourceEl = e.getTarget(v.itemSelector, 10);\r
-\r
-// If the mousedown is within a DataView node, clone the node to produce\r
-// a ddel element for use by the drag proxy. Also add application data\r
-// to the returned data object.\r
- if (sourceEl) {\r
- d = sourceEl.cloneNode(true);\r
- d.id = Ext.id();\r
- return {\r
- ddel: d,\r
- sourceEl: sourceEl,\r
- repairXY: Ext.fly(sourceEl).getXY(),\r
- sourceStore: v.store,\r
- draggedRecord: v.{@link Ext.DataView#getRecord getRecord}(sourceEl)\r
- }\r
- }\r
- },\r
-\r
-// Provide coordinates for the proxy to slide back to on failed drag.\r
-// This is the original XY coordinates of the draggable element captured\r
-// in the getDragData method.\r
- getRepairXY: function() {\r
