C++ (Cpp) HyperTextAccessible::CharAt Examples

Example #1

NS_IMETHODIMP
xpcAccessibleHyperText::GetCharacterAtOffset(int32_t aOffset,
                                             char16_t* aCharacter)

}

Example #2

File: nsMaiInterfaceText.cpp Project: Jar-win/Waterfox

  }

  if (ProxyAccessible* proxy = GetProxy(ATK_OBJECT(aText))) {
    return static_cast<gunichar>(proxy->CharAt(aOffset));
