Thanks.
My code example is :
In awakeFromNib

In -tableView:writeRowsWithIndexes:toPasteboard:
  // Next index
  anIndex = [selectedRowIndexSet indexGreaterThanIndex:anIndex];
}
...

Item Reference:     19884c10
 Item Bounds (tlbr): { 86, 1, 104, 191 }
 Number of flavors: 0

Strangely, it doesn't have any flavor of data.
Thank you in advance.
Hi,
When I dragged the same file from the Finder to the FCP, it shows :
Number of Items: 1
1. Item Reference: 19884c10
Item Bounds (tlbr): { 86, 1, 104, 191 }
Number of flavors: 2
1. Flavor Type: 'furl'
Flavor Flags: 0

But if I drag one from my application to the FCP, it shows :

1. Item Reference: c0c0a

The major difference between those are in the 2nd flavor type 'hfs'.
Their flavor flags are different: one is 300, while the other is 0.
Thank you.

Hi. I read a post at
http://cocoadev.com/forums/comments.php?DiscussionID=612 and wonder if
it is not possible to make current Cocoa apps behave like the Finder.
Is it still valid to use NSCreateFilenamePboard() function?

When I used a returned string by calling the function, the Drag&Drop
informaiton is quite different from that from the Finder.

Even when I try NSURLPboardType with declareType.., it didn't generate
matching "fURL" flavor.

And it doesn't seem to me that it is possible to make "hfs" flavor also.
With NSFilenamesPboardType, it can generate the "fURL" and "hfs" flavor,
though.

Should I use some Carbon calls?
-- My previous post.. --

Hello. I found out that NSCreateFilenamePboardType() would help. So, I
tried it like :

NSString *quicktimeFileNamesPboardType =
NSCreateFilenamePboardType(@"mov");
[myNSTableView registerForDraggedTypes:[NSArray
arryWithObject:quickTimeFileNamesPboardType]];

NSString *quicktimeFileNamesPboardType =
NSCreateFilenamePboardType(@"mov");
anIndex = [selectedRowsIndexSet firstIndex];

while( anIndex != NSNotFound )

{

  fileName = [NSString stringWithFormat:@"%@/%@.mov", configPath,
[[dataArray objectAtIndex:anIndex] name]];

  [fileNamesArray addObject:fileName];
[pboard declareTypes:[NSArray
arrayWithObjects:quicktimeFilenamesPboardType, nil] owner:nil];

isSuccessful = [pboard setPropertyList:fileNamesArray
forType:quicktimeFilenamesPboardType];

When I check what information is exported from my program with the Drag
Peeker X, it shows :
Is there anything wrong how I use the NSCreateNSFilenamePboardType? How
to use it properly?
P.S. By the way, is it normal to put 'furl' and 'hfs' flavor when
NSFilenamesPboardType is used? Because an array of file names are added
to the pasteboard, I thought that only file name strings were added. But
it turned out no-so-true.

Thanks to a utility program, called DragPeeker X, I found out some
clue why the FCP treated dragged file as a file with unknown type.

( I also tried NSURLPboardType and NSFileContentsPboardType. But they
didn't make information like above appear. )

The PboardType I used was NSFilenamesPboardType.
What actually matters, I think, is the data of the 2nd flavor.

The one using the Finder starts with MooV????, which says that the
dragged item is a QuickTime movie, while the one from my application
doesn't contain anything. ( all 0's. )
So, is there any way to mark that the interested file is in a specific
type, i.e. QuickTime movie file?
