Thanks for the info. That turned out to be a really long side quest.
Had to get into NSCell's and went into areas of NSSecureTextField that
I shouldn't have.
Anyway, I have my field editor mostly working, but I have one follow
up issue. I originally was using:
- (void) controlTextDidBeginEditing:(NSNotification*)notification
to get an event callback when the field begins editing.
It seems that once I added my custom field editor, I no longer get
this callback. Strangely, I still get the callback for:
- (void) controlTextDidEndEditing:(NSNotification*)notification
Is there something I can do to get that first callback back working
again, or is there a substitute? (Currently my workaround is to keep a
bool on my shouldChangeCharactersInRange: to know if I just started
editing, but I would like to know if there is something more elegant.)
Thanks,
Eric
