notifyDrop

public boolean notifyDrop(DragSource source,
                          EventObject e,
                          DragData data)

The function DragSource calls once to notify this drop target that the dragged item has been dropped on it. This method has no default implementation and returns false, so you must provide an implementation that does something to process the drop event and returns true so that the drag source's repair action does not run.

Parameters:

source - the drag source

e - the event object

data - an object containing arbitrary data supplied by the drag source

Returns:

true if the drop was valid, else false

notifyEnter

public java.lang.String notifyEnter(DragSource source,
                                    EventObject e,
                                    DragData data)

The function a DragSource calls once to notify this drop target that the source is now over the target. This default implementation adds the CSS class specified by overClass (if any) to the drop element and returns the dropAllowed config value. This method should be overridden if drop validation is required.

Parameters:

source - The drag source that was dragged over this drop target

e - The event

data - An object containing arbitrary data supplied by the drag source

Returns:

The CSS class that communicates the drop status back to the source so that the underlying StatusProxy can be updated

notifyOut

public void notifyOut(DragSource source,
                      EventObject e,
                      DragData data)

The function a Ext.dd.DragSource calls once to notify this drop target that the source has been dragged out of the target without dropping. This default implementation simply removes the CSS class specified by overClass (if any) from the drop element.

Parameters:

source -

e -

data -

notifyOver

public java.lang.String notifyOver(DragSource source,
                                   EventObject e,
                                   DragData data)
