This class provides a container DD instance that allows dragging of multiple child source nodes.

- *

This class does not move the drag target nodes, but a proxy element which may contain - * any DOM structure you wish. The DOM element to show in the proxy is provided by either a - * provided implementation of {@link #getDragData}, or by registered draggables registered with {@link Ext.dd.Registry}

- *

If you wish to provide draggability for an arbitrary number of DOM nodes, each of which represent some - * application object (For example nodes in a {@link Ext.DataView DataView}) then use of this class - * is the most efficient way to "activate" those nodes.

- *

By default, this class requires that draggable child nodes are registered with {@link Ext.dd.Registry}. - * However a simpler way to allow a DragZone to manage any number of draggable elements is to configure - * the DragZone with an implementation of the {@link #getDragData} method which interrogates the passed - * mouse event to see if it has taken place within an element, or class of elements. This is easily done - * by using the event's {@link Ext.EventObject#getTarget getTarget} method to identify a node based on a - * {@link Ext.DomQuery} selector. For example, to make the nodes of a DataView draggable, use the following - * technique. Knowledge of the use of the DataView is required:


-myDataView.on('render', function(v) {
-    myDataView.dragZone = new Ext.dd.DragZone(v.getEl(), {
-
-//      On receipt of a mousedown event, see if it is within a DataView node.
-//      Return a drag data object if so.
-        getDragData: function(e) {
-
-//          Use the DataView's own itemSelector (a mandatory property) to
-//          test if the mousedown is within one of the DataView's nodes.
-            var sourceEl = e.getTarget(v.itemSelector, 10);
-
-//          If the mousedown is within a DataView node, clone the node to produce
-//          a ddel element for use by the drag proxy. Also add application data
-//          to the returned data object.
-            if (sourceEl) {
-                d = sourceEl.cloneNode(true);
-                d.id = Ext.id();
-                return {
-                    ddel: d,
-                    sourceEl: sourceEl,
-                    repairXY: Ext.fly(sourceEl).getXY(),
-                    sourceStore: v.store,
-                    draggedRecord: v.{@link Ext.DataView#getRecord getRecord}(sourceEl)
-                }
-            }
-        },
-
-//      Provide coordinates for the proxy to slide back to on failed drag.
-//      This is the original XY coordinates of the draggable element captured
-//      in the getDragData method.
-        getRepairXY: function() {
-            return this.dragData.repairXY;
-        }
-    });

This class provides a container DD instance that allows dropping on multiple child target nodes.

- *

By default, this class requires that child nodes accepting drop are registered with {@link Ext.dd.Registry}. - * However a simpler way to allow a DropZone to manage any number of target elements is to configure the - * DropZone with an implementation of {@link #getTargetFromEvent} which interrogates the passed - * mouse event to see if it has taken place within an element, or class of elements. This is easily done - * by using the event's {@link Ext.EventObject#getTarget getTarget} method to identify a node based on a - * {@link Ext.DomQuery} selector.

- *

Once the DropZone has detected through calling getTargetFromEvent, that the mouse is over - * a drop target, that target is passed as the first parameter to {@link #onNodeEnter}, {@link #onNodeOver}, - * {@link #onNodeOut}, {@link #onNodeDrop}. You may configure the instance of DropZone with implementations - * of these methods to provide application-specific behaviour for these events to update both - * application state, and UI state.

- *

For example to make a GridPanel a cooperating target with the example illustrated in - * {@link Ext.dd.DragZone DragZone}, the following technique might be used:


-myGridPanel.on('render', function() {
-    myGridPanel.dropZone = new Ext.dd.DropZone(myGridPanel.getView().scroller, {
-
-//      If the mouse is over a grid row, return that node. This is
-//      provided as the "target" parameter in all "onNodeXXXX" node event handling functions
-        getTargetFromEvent: function(e) {
-            return e.getTarget(myGridPanel.getView().rowSelector);
-        },
-
-//      On entry into a target node, highlight that node.
-        onNodeEnter : function(target, dd, e, data){ 
-            Ext.fly(target).addClass('my-row-highlight-class');
-        },
-
-//      On exit from a target node, unhighlight that node.
-        onNodeOut : function(target, dd, e, data){ 
-            Ext.fly(target).removeClass('my-row-highlight-class');
-        },
-
-//      While over a target node, return the default drop allowed class which
-//      places a "tick" icon into the drag proxy.
-        onNodeOver : function(target, dd, e, data){ 
-            return Ext.dd.DropZone.prototype.dropAllowed;
-        },
-
-//      On node drop we can interrogate the target to find the underlying
-//      application object that is the real target of the dragged data.
-//      In this case, it is a Record in the GridPanel's Store.
-//      We can use the data set up by the DragZone's getDragData method to read
-//      any data we decided to attach in the DragZone's getDragData method.
-        onNodeDrop : function(target, dd, e, data){
-            var rowIndex = myGridPanel.getView().findRowIndex(target);
-            var r = myGridPanel.getStore().getAt(rowIndex);
-            Ext.Msg.alert('Drop gesture', 'Dropped Record id ' + data.draggedRecord.id +
-                ' on Record id ' + r.id);
-            return true;
-        }
-    });
