Updating the trash icon without NSWorkspace

Hi Cocoabuilders,




I know there have been similar threads on here before, but they don't 
address my particular issue.

I'm using NSFileManager methods to move files into the trash. As has 
been mentioned by others, this doesn't update the trash icon in the doc.

I know I could use the NSWorkspace method performFileOperation… but 
the catch is I want to be able to undo the move, which means I would 
need to know the path to which the file was moved. However 
NSWorkspace may rename the file to prevent collisions. If this is the 
case, I wont have any way to find the new path to the file (other 
than guessing).

There are probably tricks that could be used to get this to work, but 
I wonder if there isn't a simple notification that can be raised to 
cause the trash icon to update?

In any case, I would also need to update it when taking files out of 
the trash, in which case NSWorkspace is no help.

Who manages this icon? Is it the Finder? or the Doc? Is there an API 
that can help here?

Thanks for your help.




Cheers,
Lach
