Currently it contains functions that support copy and paste through local id, as well as a debugging function, runtime conformance checks, and a function to shorten the title of a cell to fit within its bounds. */ #import <appkit/Pasteboard.h> /* ========================================================================== */ /* An IKIconObject must be able to write itself to a pasteboard, and its class must be able to read back instances from the pasteboard. The IconKit provides a simple way to do this using an object's id. Such dragging works only within a single application, so programmers will need to set up a more elaborate mechanism for interapplication dragging. The FileViewer example gives a good illustration. -WARNING- The IKidPboardType is globally available to mimic the way one uses the standard pasteboard types. However, it must get initialized to a random string (very important) before being used. Calls to IKInitIDpboardType() are scattered about the IconKit in all the class initialization methods, so you should be safe. But if you somehow manage to bypass them all, be sure to call IKInitIDpboardType() yourself. */ extern NXAtom IKidPboardType; extern void IKInitIDpboardType (void); extern void IKCopyID (Pasteboard * pboard, id object); extern id IKReadID (Pasteboard * pboard); extern NXAtom * IKIDPasteTypes (void); extern void IKdprintf (const char * format, ...); extern void IKSetDebug (BOOL flag); extern BOOL IKCheckConformance (id object); extern void IKShortenTitle (Cell * text, float maxWidth);
