Qt的; 没有匹配的通话功能

Question

Getting this error in a Qt project;

C:\Users\Seb\Desktop\SDIcw2\shipHandler.cpp:20: error: no matching function for call to 'std::basic_ifstream<char>::open(QString&)'
     infile.open(qstr);
                     ^

Happening in this constructor;

SDI::shipHandler::shipHandler(std::string fileName)
{
    QString qstr = QString::fromStdString(fileName.c_str());
    std::string line;
    std::ifstream infile;
    infile.open(qstr);
    while(!infile.eof()) 
    {
        getline(infile,line); 
        shipHandler::lineParse(line);
    }
    infile.close();
}

I'm creating initializing the class in another thread by;

SDI::shipHandler sh("ships.txt");

Only just solved a problem on Qt and its brought about another problem. Really getting annoyed with this and I hate posting a lot on here. Simply trying to pass the file name to open, worked in visual studio but moving here to add the gui. Help is GREATLY appreciated

Converting to the QString is just causing you problems. The compiler error should be solved if you just use fileName directly:

SDI::shipHandler::shipHandler(std::string fileName)
{
    std::string line;
    std::ifstream infile;
    infile.open(fileName);
    ...
