A few rough steps:
- See whether there is a service registry for layout related tips. Failed.
- What is specific about those note tips, is there any IID_ITIP implemented by a notes related plugin? I've used grep on a self generated dump of IObjectModel, but NoteID.h should be sufficient. That would be kNoteLayoutTipImpl, there is also one for galley mode.
Copy paste "kNoteLayoutTipImpl" into OSX search, the next second has me reading sdkdocs/html/classkNoteDataBoss.
Other interfaces on kNoteDataBoss indicate something about "owned item". For a second proof that this is really a path to go I'd set a breakpoint within kNoteLayoutTipImpl, and see how it is reached. (I did not do that, just assuming OwnedItem approach)
Revisit IOwnedItem related interfaces. IOwnedItem, then IOwnedItemIBeamData. You're seeing these tips only in text mode, are you? Then that's deeply customized behaviour, probably a tracker created by IOwnedItemIBeamData. classITracker.html lists several bosses with "Note" within them.
So the question is, would you reimplement your feature as owned item?
