qt - QFile,QFile::open: File access not specified, Opening file failed -

simple problem, can't open/create file. it's supposed save settings in xml-file given path.

i call method this:

xmlwriter->write_settings("./settings.xml");

int xmlwriter::write_settings(qstring path) {     qdebug() << "path is: " + path;      qdomdocument document;      qdomelement root = document.createelement("settings");     document.appendchild(root);      qdomelement node;     node.setattribute("name", "its me!");     node.setattribute("series", "25");     node.setattribute("pmt", "200");      root.appendchild(node);      qfile file(path);     if(!file.open(qiodevice::readwrite, qiodevice::text))     {         qdebug() << "opening file failed!";         return 1;     }     else     {         qtextstream stream(&file);         stream << document.tostring();         file.close();         qdebug() << "wrote file " + path;         return 0;     } } 

you don't pass parameters correctly, invoke polymorphic version of qfile::open

try this:

qfile file(path); if(!file.open(qiodevice::readwrite | qiodevice::text)) {       qdebug() << "opening file failed!";      return 1; } else {     qtextstream stream(&file);     stream << document.tostring();     file.close();     qdebug() << "wrote file " + path;     return 0; }
