- * @class Ext.dd.DragZone
- * @extends Ext.dd.DragSource
- * 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;
- }
- });
-});
- * See the {@link Ext.dd.DropZone DropZone} documentation for details about building a DropZone which

- * @class Ext.dd.DropZone
- * @extends Ext.dd.DropTarget
- * 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;
- }
