Hi Aki,
My NSTextView subclass has two modes of display; hidden and visible.
When editing in hidden mode, each character entered is displayed as a
random sequence of white-space characters. Editing in visible mode is
the same as editing in a stock NSTextView. The idea is to prevent
someone from determining the length or content of the edited text, but
if the diacritical marks show up, that instantly gives an observer a
clue about the nature of the edited text.
Correct me if I'm wrong, but if I simply prevent keyDown from calling
interpretKeyEvents, won't that bypass the TSM? I realize this isn't very
friendly, but I know of no other solution.
Thanks!
Jeff

Jeff,
The marked deadkey display is tightly coupled with the processing in
TSM.
Currently there is no way to de-couple them easily.
Besides, it is part of, not yet officially documented, Aqua guideline.
Could you give me some more info why you need to disable it ?
Thanks,
Aki

I'm having some problems with diacritical marks in my NSTextView
subclass. I would like to have full control over which characters are
displayed in my view, but despite my many attempts, I can't fully
control the display of these diacritical marks (they just keep
displaying regardless of how hard I try to prevent them from popping
up). In particular, when adding i (option-e + e) to my view, I would
like it to discard the initial keystroke and only display the
composite character (after the second 'e' is typed). I've looked at
the NSTextInput protocol, and setMarkedText:range: looks promising,
but simply overriding it and having it do nothing seems to cause
problems when the composite character is supposed to be added.
Can someone shed some light on how I can prevent these marks from
drawing in my view?
Thanks in advance,
Jeff
