Hi Markus,

Yes, I'm conforming to all the protocols, and I'm registering for the dragged 
types - actually that pertains to receiving only, but I can drag and receive 
the same types. Temporarily turning off the registering for dragged types (so 
that the same view won't immediately start responding to the drag it started) 
doesn't fix things, so that isn't a cause of what I'm seeing.

It's most odd - nothing is logged that might give a clue. The legacy code still 
works perfectly.


I agree, it's odd. Maybe something wrong with the image (unlikely if the code 
you posted is what you're using and it's working with the old API)? If nothing 
else helps: Did you try turning it off and on again?™


Regards
Markus

I'm updating some older code that uses the now-deprecated [NSView

though my instinct tells me not to fix code that isn't broken.

Sadly its replacement is broken.

 In order to use NSDraggingItem, I first need to make sure the stuff I'm
 dragging supports NSPasteboardWriting. I've done that, it seems
 straightforward enough. Then I build a NSDraggingItem and use the same
 image I previously used, so there's nothing new there. Finally I use
 [NSView beginDraggingSessionWithItems:event:source:].
 
 Nothing shows up. No image, nothing drags. I can break on the
 NSPasteboardWriting methods and see that they are being called, so it
 seems to be trying to write the correct things to the pasteboard. Nothing
 is logged. After this, use of the legacy dragging methods elsewhere in
 the app also fail to work - it's like whatever I did in this drag session
 messes up the dragging system altogether. Obviously I'm doing something
 wrong, but I've been over the docs and am just not getting it.

Does the source implement the required method -[NSDraggingSource
draggingSession:sourceOperationMaskForDraggingContext:]? This is the new
replacement for -draggingSourceOperationMaskForLocal:.

Ah, thanks - It wasn't - but having corrected that, it hasn't fixed my issue.

I've also checked whether the immediate return of the new method would cause a 
problem (e.g. if the caller were doing stuff after starting the drag that was 
assuming the drag had completed). It's not - in fact it's just being called 
from a simple -[NSView mouseDown:] event handler with no other code.
