How to obtain IconRef from Application Resources

Question

I want to add custom place to Finder Favorites sidebar using LSSharedFileList API as described here. But I need to add a custom icon to this item. The icon should be in the IconRef type. I have not found a way to do it. Found only a mention of the fact that the need to use Icon Services. But how?

If you will set folder icon using [[NSWokspace sharedWorkspace] setIcon:someIcon forFile:someFile options:0]; that will appear in finder sidebar. — Parag Bafna, Sep 05 '12 at 14:09

You can use this function of Scplugin.

static IconRef IconRefFromIconFileNoCache(CFStringRef file)
{
    IconRef iconRef;
    IconFamilyHandle iconFamily;
    FSRef fileRef;
    CFURLRef url;
    Boolean ok;

    url = CFURLCreateWithFileSystemPath(NULL,file,kCFURLPOSIXPathStyle,false);
    if (!url)
        return 0;

    ok = CFURLGetFSRef(url,&fileRef);
    CFRelease(url);
    if (!ok)
        return 0;


    if (ReadIconFromFSRef(&fileRef, &iconFamily))
        return nil;

    iconRef = 0;
    HLock((Handle)iconFamily);
    GetIconRefFromIconFamilyPtr(*iconFamily,(**iconFamily).resourceSize,&iconRef);
    DisposeHandle((Handle)iconFamily);

    return iconRef;
}

If one happens to have an `NSURL*`, one can cast that as `CFURLRef` and pass it to `CFURLGetFSRef`. – JWWalker Sep 05 '12 at 18:48

This works, but unfortunately not suitable for use with `LSSharedFileListInsertItemURL` on Mac OS X >= 10.7 – ZeroDivisi0n Oct 04 '12 at 17:05
