Delete Drag and Drop Behavior of IKImageBrowserView

Question

Hi Everyone:

By default (it seems), IKImageBrowserView enables drag and drop to locations in the Finder. I would like to turn off this behavior but am unsure of how to do so. I was thinking that perhaps implementing the NSDraggingDestination protocol and overriding it could solve this, but so far it hasn't worked for me.

Thanks for any help!

If you want to customize IKImageBrowserView's drag and drop behavior, you can implement the - (NSUInteger) imageBrowser:(IKImageBrowserView *) aBrowser writeItemsAtIndexes:(NSIndexSet *) itemIndexes toPasteboard:(NSPasteboard *)pasteboard method in your browser's data source object. That will let you define what types and data you want to put on the pasteboard when doing a drag. If you want to disable dragging entirely, you should be able to just return 0 (the number of items you want to be dragged).
