- * @class Ext.dd.DropZone\r
- * @extends Ext.dd.DropTarget\r
- * <p>This class provides a container DD instance that allows dropping on multiple child target nodes.</p>\r
- * <p>By default, this class requires that child nodes accepting drop are registered with {@link Ext.dd.Registry}.\r
- * However a simpler way to allow a DropZone to manage any number of target elements is to configure the\r
- * DropZone with an implementation of {@link #getTargetFromEvent} 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.</p>\r
- * <p>Once the DropZone has detected through calling getTargetFromEvent, that the mouse is over\r
- * a drop target, that target is passed as the first parameter to {@link #onNodeEnter}, {@link #onNodeOver},\r
- * {@link #onNodeOut}, {@link #onNodeDrop}. You may configure the instance of DropZone with implementations\r
- * of these methods to provide application-specific behaviour for these events to update both\r
- * application state, and UI state.</p>\r
- * <p>For example to make a GridPanel a cooperating target with the example illustrated in\r
- * {@link Ext.dd.DragZone DragZone}, the following technique might be used:</p><pre><code>\r
-myGridPanel.on('render', function() {\r
- myGridPanel.dropZone = new Ext.dd.DropZone(myGridPanel.getView().scroller, {\r
-\r
-// If the mouse is over a grid row, return that node. This is\r
-// provided as the "target" parameter in all "onNodeXXXX" node event handling functions\r
- getTargetFromEvent: function(e) {\r
- return e.getTarget(myGridPanel.getView().rowSelector);\r
- },\r
-\r
-// On entry into a target node, highlight that node.\r
- onNodeEnter : function(target, dd, e, data){ \r
- Ext.fly(target).addClass('my-row-highlight-class');\r
- },\r
-\r
-// On exit from a target node, unhighlight that node.\r
- onNodeOut : function(target, dd, e, data){ \r
- Ext.fly(target).removeClass('my-row-highlight-class');\r
- },\r
-\r
-// While over a target node, return the default drop allowed class which\r
-// places a "tick" icon into the drag proxy.\r
- onNodeOver : function(target, dd, e, data){ \r
- return Ext.dd.DropZone.prototype.dropAllowed;\r
- },\r
-\r
-// On node drop we can interrogate the target to find the underlying\r
-// application object that is the real target of the dragged data.\r
-// In this case, it is a Record in the GridPanel's Store.\r
-// We can use the data set up by the DragZone's getDragData method to read\r
-// any data we decided to attach in the DragZone's getDragData method.\r
- onNodeDrop : function(target, dd, e, data){\r
- var rowIndex = myGridPanel.getView().findRowIndex(target);\r
- var r = myGridPanel.getStore().getAt(rowIndex);\r
- Ext.Msg.alert('Drop gesture', 'Dropped Record id ' + data.draggedRecord.id +\r
- ' on Record id ' + r.id);\r
- return true;\r
- }\r
- });\r
