Title Body

You know that effect when you drag out an item from the dock and that cloud drag cursor appears and when you let go it disappears with a poof effect? Similarly, in Xcode when you drag a breakpoint outside the line number gutter the same happens. I would like to implement the same effect in my application but can't find the right way. I have an NSImageView descendant to implement the NSDraggingSource and NSDraggingDestination protocols. I have several instances of this view which allow to drag their content between the others (a copy operation takes place in this scenario, but that's only relevant to show I have drag'n drop implmented and fully working for standard tasks). Now, when I drag out an image from its view to anywhere (except another view instance) I want to have the delete operation taking place on drop. However the drag operation is fully controlled by the target view. I could manage to make them respond the way I want (even though this would be a lot of work), but it fails completely if I'm dragging outside my application. If I could get the delete drag operation I could handle this however easily by: - (void)draggedImage: (NSImage *)image endedAt: (NSPoint)screenPoint operation: (NSDragOperation)operation { if (operation == NSDragOperationDelete) { NSRect rect = [self.window convertRectToScreen: [self convertRect: self.frame fromView: nil]]; NSShowAnimationEffect(NSAnimationEffectPoof, rect.origin, self.bounds.size, nil, nil, NULL); } } I tried already to set the delete cursor like this: - (void)draggingSession: (NSDraggingSession *)session movedToPoint: (NSPoint)screenPoint { if (!NSPointInRect(screenPoint, self.window.frame)) { [[NSCursor disappearingItemCursor] set]; } } (for simplicity this is for the entire windw at the moment). This works as long as I don't hit the desktop
