objective c - Drag file from NSTableView to other osx application -


i want drag file nstableview row copy application (i.e. finder). implemented first 2 steps ('configuring table view', 'beginning drag operation') of guide , thought trick: http://developer.apple.com/library/mac/#documentation/cocoa/conceptual/tableview/tasks/usingdraganddrop.html

however, when attempt drag row, row text follows mouse file not copy when released. here's i'm sending uitableview upon initialization:

#define librarysongdatatype @"nsfilecontentspboardtype" - (void)awakefromnib {     [self setdraggingsourceoperationmask:nsuintegermax forlocal:yes]; // allow interapplication drags     [self registerfordraggedtypes:[nsarray arraywithobject:librarysongdatatype] ]; // nsfilecontentspboardtype }

here's how i'm handling drag in nstableview's data source (an nsarraycontroller):

- (bool)tableview:(nstableview *)atableview writerowswithindexes:(nsindexset *)rowindexes topasteboard:(nspasteboard *)pboard {     nslog(@"writerowswithindexes");     nsdata *data = [nskeyedarchiver archiveddatawithrootobject:rowindexes];     [pboard setdata:data fortype:librarysongdatatype];     return yes; }

to clear, i'm not trying drag files table view, i'm trying drag file(s) out of it.

firstly, document did refer when wrote line ?

 [self setdraggingsourceoperationmask:nsuintegermax forlocal:yes];

this doesn't make sense. don't use nsuintegermax. use operation masks defined here. it's written there nsuintegermax stands everything, shouldn't use it; apple may re-define bit in future. should use nsdragoperationcopy or specific. if copied line webpage or book, should stop trusting book/webpage.

secondly, forlocal: should no pass data application; local here means application local.

third, instead of setting archived data in 

 [pboard setdata:data fortype:librarysongdatatype];

consider making nsfilewrapper , set using writefilewrapper:, see here. way can specify file name created in finder. otherwise, system doesn't have idea data represent.
