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() {
- myDataView.dragZone = new Ext.dd.DragZone(myDataView.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(myDataView.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: myDataView.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;
- }
- });
-});
- * See the {@link Ext.dd.DropZone DropZone} documentation for details about building a DropZone which
- * cooperates with this DragZone.
