Thanks Gregory, that did the trick.
I actually didn't need your "step 2" (putting the anchors in the
Info.plist); using a helpindex worked fine on 10.4. But I did need to
explicitly register the help book.
Incidentally, I was able to shortcut the Apple example code slightly using
NSPreferencePane's 'bundle' method:
- (void) registerHelpBook
{
NSString * bundlePath = [[self bundle] bundlePath];
OSStatus err;
FSRef fsref;
err = FSPathMakeRef (
(const void *) [bundlePath UTF8String], & fsref, NULL
);
if (err != noErr)
{
NSLog (@"Could not get path for bundle - no Apple Help for
myPrefPane\n");
return;
}
err = AHRegisterHelpBook (& fsref);
if (err != noErr)
{
NSLog (@"Could not register Apple Help for myPrefPane\n");
}
}
PS: I couldn't see any call to deallocate a FSRef. Does it get correctly
cleaned up as part of normal stack cleanup?
Not that a small memory leak here would be a big problem, since it's called
exactly once.
