Problem with QDir::mkdir() and vector of QStrings

[legolizard]

I have a problem with QDir::mkdir().

I have a vector of QStrings and would like to make a new directory (in a given folder) named off of one of the QStrings in the vector, however, it fails to do so. Code:

QDir dir(/*path*/);
QString newPath = rawData[ 9 ];// rawData is the vector of QStrings
dir.mkdir( newPath );

QDir dir(/*path*/);
QString newPath = rawData[ 9 ];// rawData is the vector of QStrings
dir.mkdir( newPath );

When I output newPath, everything is okay, yet Qdi::mkdir fails for no apparent reason. T_T

Any help would be greatly appreciated.

Even though there is no apparent reason, apparently there is a reason... It might be something hard to notice, like a trailing newline or other invisible character -- which is why people should always post some more code than where the problem exhibits. It is a question of how the variable & data has been created.

No, I have outputed rawData[9] as well, whilst debugging, and it is exactly what it should be. In fact I have outputted the entire vector, and everything is correct. If you would like me to post some more code then sure. : )

I input into the vector with this function:

signed int FileSystem::readFromFile(){
  std::string tmp = selectedFilePath.toStdString();//selectedFilePath is a QString of file path I am going to read. It is initalized else where in the program.
  std::ifstream ifs;
  ifs.open( tmp.c_str() );
  if( ifs.is_open() ){
        while( getline( ifs , tmp ) ){
            if(rawData.size() < MAX_LINES){ // Max_SIZE is a constant I define elsewhere in the program.
                rawData.push_back( QString::fromStdString( tmp ) );//Enter data into vector.
              }
          }
      return EXIT_SUCCESS;
    }
  else return EXIT_FAILURE;
}

signed int FileSystem::readFromFile(){
  std::string tmp = selectedFilePath.toStdString();//selectedFilePath is a QString of file path I am going to read. It is initalized else where in the program.
  std::ifstream ifs;
  ifs.open( tmp.c_str() );
  if( ifs.is_open() ){
        while( getline( ifs , tmp ) ){
            if(rawData.size() < MAX_LINES){ // Max_SIZE is a constant I define elsewhere in the program.
                rawData.push_back( QString::fromStdString( tmp ) );//Enter data into vector.
              }
          }
      return EXIT_SUCCESS;
    }
  else return EXIT_FAILURE;
}

Again, I have outputted the vector and everything is correct. It is quite confusing. :/
