Looking at Preview.app's info.plist, it appears to provide an icon for files of the type 'JPEG' and creator 'prvw':

<key>CFBundleSignature</key>
<string>prvw</string>
...
<key>CFBundleTypeOSTypes</key>
<array>
<string>JPEG</string>
</array>

However, if I call IconServices to get an IconRef to this icon:

GetIconRef(kOnAppropriateDisk, 'prvw', 'JPEG', &iconRef);

...it returns a generic document icon. This same code path *does* work for other applications such as GraphicConverter, PhotoShop, ImageReady, etc.

Yes Preview.app is in my /Applications dir -- and I've tried the constants kOnSystemDisk and kUserDomain without effect. I've also tried this for every file type that Preview.app purports to support, and it doesn't work.

So what am I doing wrong, or is IconServices still not quite complete?

I would bet not complete. Though I am just guessing...

But Moki as El Pres of Ambrosia don't you have contacts inside apple? Fire off a email and ask if it's not fully implemented, as what you are doing *should* work.

Methinks I once saw something about getting icons in LaunchServices that might work...

Anyway, I'm pretty sure I heard that Icon Services has some bugs under OS X. I'd suggest trying the LaunchServices calls first, though.

It turns out to be yet another limitation in the OS X Carbon APIs -- if IconServices will just return what icons are in the OS 9 desktop database file (if you have one), which of course won't include applications that doesn't include OS 9-style bundles (such as Cocoa apps).

As a (lame) work-around, I simply create a temporary file of the type/creator I want an icon to, and call GetIconRefFromFile() on it.

Silly, slow, and inefficient, but it works. :/

not very elegant, either, but you could open the (cocoa) app's Contents/Info.plist and then look at the key for CFBundleIconFile and assemble the path...

as i said, not very elegant, but should work...
