Please point me in the right direction.
[forgot to copy the list] The process is the same for window or view, basically just need to implement the NSDraggingDestination protocol and register the dragging types your interested in. The advantage of adding dragging support to the window is that you can drop your folder onto anything inside the window. The drag and drop guide is very good, start here: <http://developer.apple.com/mac/library/documentation/cocoa/Conceptual/DragandDrop/DragandDrop.html#//apple_ref/doc/uid/10000069i> File dragging got its own chapter: <http://developer.apple.com/mac/library/documentation/cocoa/Conceptual/DragandDrop/Tasks/DraggingFiles.html#//apple_ref/doc/uid/20001288-CEGJFDFG> Regards Markus -- __________________________________________ Markus Spoettl _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
