Response to: Making the view a dragging destination


I added the drag and drop code, but dragging an image only works after I have opened an image.


Is there a way that the drag event work when the inital window appears.


Thanks

    Basically no, because while dragging an image you put the data (raw, bitmap, etc..) in a NSImage which will be put in turn into an NSImageView.

    That's why you need an existing NSImage (even transparent one) to drag another into it. See the Composite Lab example in AppKit for more details.
