Copy Qt resource file into filesystem

thanhxp

Hi all,
I want to copy a resource file into my current directory containing the executable file. The copy file should be in folder abc (not existed) inside my current directory.
I am using QFile::copy() methods like this:

#include <QCoreApplication>
#include <QFile>
#include <QString>
#include <QDebug>
#include <QTextStream>
#include <iostream>

using namespace std;

void read(QString filename)
{
    QFile file(filename);
    if(!file.open(QFile::ReadOnly |
                  QFile::Text))
    {
        qDebug() << " Could not open the file for reading";
        return;
    }

    QTextStream in(&file);
    QString myText = in.readAll();

    // put QString into qDebug stream
    qDebug() << myText;

    file.close();
}

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    read(":/resources/hello.pro");
    bool status = QFile::copy(":/resources/hello.pro" , "./abc/hel.pro");
    if(status) {
            cout << "Success" << endl;
        } else {
            cout << "Failed" << endl;
        }


    return 0;
}

The problem is that, when I run the executable file, it returns failed.
I am expecting that it will create new directory abc inside my current folder then copy the resource file into that.
Can anyone help me?

Thanks and best regards.

That is a wrong assumption: copy() will not create any directories. You have to create it by yourself, see QDir (http://doc.qt.io/qt-5.7/qdir.html#mkdir).

Thank you very much. I will redesign my program with QDir.
Best regards.
