Can not read text file with Qt 5
c++, qt
Solution
Probably because `plain.txt` does not exist in the current working directory or in the PATH. Make sure the file is in the working directory or pass the absolute path to `QFile`.
Also see what `QFile::exists` returns.
Problem
I wrote a simple code to open plain text file with Qt 5's QFile as seen below; ``` // main.cpp #include <iostream> using std::endl; using std::cout; #include <QCoreApplication> #include <QFile> #include <QIODevice> int main(int argc, char *argv[]) { QCoreApplication a(argc, argv); QFile plainFile("plain.txt"); if(plainFile.open(QIODevice::ReadOnly | QIODevice::Text)) { cout << "File opened successfull" << endl; plainFile.close(); } else{ cout << "could not open file." << endl; } return a.exec(); } ``` The output when compiled and run is "could not open file". What am I do wrong?
