Hi,
Usually, you should call
-dragPromisedFilesOfTypes:fromRect:source:slideBack:event: to initiate
a promise drag. And implement the method of NSDraggingInfo protocol -
(NSArray *)namesOfPromisedFilesDroppedAtDestination:(NSURL
*)dropDestination which will be called from drag destination if it
receive such kind of drag.
for more detail please refer to:

Hi,
I am in the process of adding image viewing to my postgresql
browser.
I can build the image from data stored in the DB and display
the rascal in a scrolled image view.
I can also copy the resulting image to the "clip board".
I would like to be able to drag the image to the desktop...
I understand that I would have to make the imageview a
dragging source, note there is no filename for the image
at this point.
Does the finder accept drags to the desktop for nameless data?
Thanks,
Jerry
