Store last error message somewhere

[novalisek]

Hi,
would it be possible not just to do

 //part of openFile function

    if (false == CheckFile(filePath, true))
    {
        qDebug() << __FUNCTION__ << "Error - wrong file path:" << filePath;
        return false;
    }

but do something like

    if (false == CheckFile(filePath, true))
    {
        internalError  << __FUNCTION__ << "Error - wrong file path:" << filePath;
        qDebug() <<internalError;
        return false;
    }

 QString xxx::getError()
 {
   return internalError;
  }

everywhere where qDebug() is used, so that I can get latest error message when functions returns false and then report it to user?

Thanks.
