image transition while dragging

Subject: image transition while dragging

Hi All,

I am working on dragging table row (not for re-ordering or deleting) onto a NSView.... I am returning an processed image (for dragImage) in - (NSImage *)dragImageForRowsWithIndexes:(NSIndexSet *)dragRows tableColumns:(NSArray *)tableColumns event:(NSEvent *)dragEvent offset: (NSPointPointer)dragImageOffset { // return doctoredImage; }

I want to change the dragged image with smooth transition to another image, whenever it reaches its destination(NSView) or when drag moves out of the source(NSTableView) just like the effect to the drag image in interface builder tool when items from palette are dragged out of it.

Any pointers or ideas is appreciated.

Thanks
Rajesh.
