I have implemented EditBox. The next thing I want is that the height of the EditBox be changed every time a line break occurs like in Message App. I did that with "editBoxTextChanged(cocos2d::ui::EditBox* editBox, const std::string& text)". But I have problems when using a Japanese keyboard. Characters before conversion cannot be obtained with getText(). Therefore, the height does not change even if the line breaks are repeated until Japanese is converted. Any good ideas? Help me.

The current code.

// default editbox

editBox = cocos2d::ui::EditBox::create(Size(600, 40), cocos2d::ui::Scale9Sprite::create(("abc.png")));

// Height change editbox

void HelloWorld::editBoxTextChanged(cocos2d::ui::EditBox* editBox, const std::string& text)

{
     std::string s = editBox->getText();

     if (s.length() > 18)

     {

         editBox->setContentSize(Size(600, 80));

      }

}

Thanks.
