Hi,
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.
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
Length: 54
Data:
66 69 6C 65 3A 2F 2F 6C 6F 63 61 6C 68 6F 73 74
file://localhost
2F 56 6F 6C 75 6D 65 73 2F 31 37 32 2E 31 36 2E
/Volumes/172.16.
32 34 36 2E 31 34 36 2F 4D 4F 56 2F 30 30 30 33
246.146/MOV/0003
59 42 2E 6D 6F 76
YB.mov
2. Flavor Type: 'hfs '
Flavor Flags: 300
Length: 80

But if I drag one from my application to the FCP, it shows :
Number of Items: 1
1. Item Reference: c0c0a
Item Bounds (tlbr): { 219, 244, 219, 244 }
Number of flavors: 2

( I also tried NSURLPboardType and NSFileContentsPboardType. But they
didn't make information like above appear. )
The PboardType I used was NSFilenamesPboardType.
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.
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?
Thank you.
