Sencha Documentation

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 getDragData, or by registered draggables registered with 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 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 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 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 getTarget method to identify a node based on a 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.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;
        }
    });
});

By default, drags can only be initiated if the mousedown occurs in the region the linked element is.

This property is set to true if outer handles are defined.
