Щаз вот посмотрел. Похоже что для реализации этого функционала надо чтобы все контейнеры, в которых находится ваш компонент не имели флага wxTAB_TRAVERSAL. Т.е. если надо обрабатывать TAB и ваш контрол находится где-то там во вложенных панелях, то все выше стоящие панели также не должны иметь флаг wxTAB_TRAVERSAL. Но ИМХО это не очень хороший подход. Программулина тогда accessibility-тест не пройдет. Т.е., допустим, поставили фокус на контрол а потом клавиатурой никуда из него выйти не сможем.
У меня вот такое нормально работает

# wxWANTS_CHARS:
Use this to indicate that the window wants to get all char/key events for all keys - even for keys like TAB or ENTER which are usually used for dialog navigation and which wouldn't be generated without this style. If you need to use this style in order to get the arrows or etc., but would still like to have normal keyboard navigation take place, you should call Navigate in response to the key events for Tab and Shift-Tab.
