|
|
</span></span> * @class Ext.dd.DragDrop
|
|
* Defines the interface and base operation of items that that can be
|
|
* dragged or can be drop targets. It was designed to be extended, overriding
|
|
* the event handlers for startDrag, onDrag, onDragOver and onDragOut.
|
|
* Up to three html elements can be associated with a DragDrop instance:
|
|
* <ul>
|
|
* <li>linked element: the element that is passed into the constructor.
|
|
* This is the element which defines the boundaries for interaction with
|
|
* other DragDrop objects.</li>
|
|
* <li>handle element(s): The drag operation only occurs if the element that
|
|
* was clicked matches a handle element. By default this is the linked
|
|
* element, but there are times that you will want only a portion of the
|
|
* linked element to initiate the drag operation, and the setHandleElId()
|
|
* method provides a way to define this.</li>
|
|
* <li>drag element: this represents the element that would be moved along
|
|
* with the cursor during a drag operation. By default, this is the linked
|
|
* element itself as in {@link Ext.dd.DD}. setDragElId() lets you define
|
|
* a separate element that would be moved, as in {@link Ext.dd.DDProxy}.
|
|
* </li>
|
|
* </ul>
|
|
* This class should not be instantiated until the onload event to ensure that
|
|
* the associated elements are available.
|
|
* The following would define a DragDrop obj that would interact with any
|
|
* other DragDrop obj in the "group1" group:
|
|
* <pre>
|
|
* dd = new Ext.dd.DragDrop("div1", "group1");
|
|
* </pre>
|
|
* Since none of the event handlers have been implemented, nothing would
|
|
* actually happen if you were to run the code above. Normally you would
|
|
* override this class or one of the default implementations, but you can
|
|
* also override the methods you want on an instance of the class...
|
|
* <pre>
|
|
* dd.onDragDrop = function(e, id) {
|
|
* &nbsp;&nbsp;alert("dd was dropped on " + id);
|
|
* }
|
|
* </pre>
|
|

|
|
* @param {String} id of the element that is linked to this instance
|
|
* @param {String} sGroup the group of related DragDrop objects
