I'm implementing drag and drop in an outline view.
I implement –outlineView:validateDrop:proposedItem:proposedChildIndex: to
return one of several drag operation constants depending on combinations of
source, destination and the source mask. For example the operation can be a
move or a copy
What about a category on NSPasteboard that uses an associated object to store

Dear Cocoa users,
I'm trying to implement view switching based on the view switching example
in Hillegass. I have a main window with a box that contains other views.
The following method, in the view controller class for the main window,
switches the views contained in the box and resizes the

Text will scale just fine by changing the view's bounds (or the transform)
if you are NOT using a layer-backed view. I had to abandon this approach on
the iPad because everything is layer-backed and it just scales pixels.

There are many, many questions and articles and discussions out there
about tracking down memory leaks, and finding over-release bugs.
Neither of those, AFAICT, is what's happening to me. If there's a good
article or Fine Manual out there that I should read, I haven't found

Thanks, Graham. I don't want to use NSFileManager because (AFAICT)
you can't ask it how far along it's gotten. Also I don't see a way to
cancel a copy in the middle.
I'm not familiar with these ops, but having browsed the docs just
now, it seems to me what's happening is that because
I’m trying to do something pretty simple (or so I would think). I need

OK I'm really stumped on this one. I want to make a checkbox with a

It does. Making a call to draggingSourceOperationMask in your acceptDrop
method will give you the operation that is active. No need to cache it.

The validateDrop method returns a NSDragOperation value that I compute. That is
not the same value that the [draggingInfo draggingSourceOperationMask]

the validation.
