97 * may be to have a second embedding control responsible for drawing borders
98 * and backgrounds eventually)
99 * so all this border calculations have to be taken into account when calling
100 * native methods or getting native oriented data

635 /*
636 NB: faking a charcode here is problematic. The kEventTextInputUpdateActiveInputArea event is sent
637 multiple times to update the active range during inline input, so this handler will often receive
638 uncommited text, which should usually not trigger side effects. It might be a good idea to check the
639 kEventParamTextInputSendFixLen parameter and verify if input is being confirmed (see CarbonEvents.h).
640 On the other hand, it can be useful for some applications to react to uncommitted text (for example,
641 to update a status display), as long as it does not disrupt the inline input session. Ideally, wx
642 should add new event types to support advanced text input. For now, I would keep things as they are.
643
644 However, the code that was being used caused additional problems:
645 UInt32 message = (0 << 8) + ((char)uniChars[pos] );
646 Since it simply truncated the unichar to the last byte, it ended up causing weird bugs with inline
647 input, such as switching to another field when one attempted to insert the character U+4E09 (the kanji
648 for "three"), because it was truncated to 09 (kTabCharCode), which was later "converted" to WXK_TAB
649 (still 09) in wxMacTranslateKey; or triggering the default button when one attempted to insert U+840D
650 (the kanji for "name"), which got truncated to 0D and interpreted as a carriage return keypress.
651 Note that even single-byte characters could have been misinterpreted, since MacRoman charcodes only
652 overlap with Unicode within the (7-bit) ASCII range.
653 But simply passing a NUL charcode would disable text updated events, because wxTextCtrl::OnChar checks
654 for codes within a specific range. Therefore I went for the solution seen above, which keeps ASCII
655 characters as they are and replaces the rest with '?', ensuring that update events are triggered.
656 It would be better to change wxTextCtrl::OnChar to look at the actual unicode character instead, but
657 I don't have time to look into that right now.
