Are you certain about this? If I create two NSImageViews in
Interface Builder using the image well palette item, I can drag
images from one to another.
That is interesting. I had done the same and it did not work. Are
you using any special settings for the image views? And could you
please send me your sample application?
I am using 10.6.8 and Xcode 3.2.2, maybe Apple changed things for
10.7 again?
It seems I misremembered. They accept drags but, as you say, won't
initiate them.
Rather than moving the behaviour to a subclass, could we not just
have a flag for turning it on and off? e.g. a -setInitiatesDrag:
method. That would make it a bit easier for code that subclasses
NSImageView and wants this behaviour.
This could actually by the bigger change as it requires a new ivar to
store that variable. No, I can just turn the ivar _allowsCutCopyPaste
into a bit array and get away with the same size!
Looks like the better idea, thank you!
Fred
