I came up with the code below to set the color label. Questions:
1) Is it really necessary to do a FSGetCatalogInfo first? I presume
it is because otherwise the FSSetCatalogInfo wouldn't know what
fields of catalogInfo.finderInfo it is supposed to be updating, or
even what bits of catalogInfo.fileInfo->finderFlags.
I believe that's correct.
2) I'm casting finderInfo to a (FileInfo *). But from the header
files it also mentions the FolderInfo structure in conjunction with
the finderInfo member. From my looking at FileInfo and FolderInfo it
appears as if the finderFlags are at different offsets in the
structures. Am I supposed to check if it is a directory and cast it
to one or the other depending on the result?
I think they're actually at the same offset; the Rect in FolderInfo
has 4 short members (8 bytes), which should be the same size as the
two OSType members in FinderInfo (4 bytes each). In spite of that, I
cast appropriately so I can see what's going on. It's too late for me
to think clearly, so I'll just point you to my own code for getting/
setting labels: http://code.google.com/p/fileview/source/browse/trunk/fileview/FVFinderLabel.m
(BSD license).
