How to set permissions to a file using QFile::setPermissions()

Hi, everybody. I have a problem when working with file permissions. When I create a file, its default permissions are -rw-r--r-- and now i want to add execute permission to this file. This mean its permissions must be -rwxr-xr-x. So I used these commands:

Code:

---

QString savefile = QFileDialog::getSaveFileName(this,"Save File", QDir::currentPath(),fillter0) + ".desktop";
QFile myfile(savefile);
myfile.setPermissions(QFile::ExeGroup);
myfile.setPermissions(QFile::ExeOther);
myfile.setPermissions(QFile::ExeOwner);
myfile.setPermissions(QFile::ExeUser);

---

But it doesnt work. May you help me find a solution for this. Thank you very much.

What is happening is that you are overwriting the permissions not adding to them so what you have here:

Code:

---

myfile.setPermissions(QFile::ExeGroup);
myfile.setPermissions(QFile::ExeOther);
myfile.setPermissions(QFile::ExeOwner);
myfile.setPermissions(QFile::ExeUser);

---

should look like this:

Code:

---

myfile.setPermissions(QFile::ExeGroup | QFile::ExeOther | QFile::ExeOther | QFile::ExeUser);

---

so that you apply all of the permissions at the same time.

thank you for your supply, but your suggest doesnt work to. I have changed my code like this:

Code:

---

QString savefile = QFileDialog::getSaveFileName(this,"Save File", QDir::currentPath(),fillter0) + ".desktop";
    QFile myfile(savefile);
 
    if(!myfile.setPermissions(QFile::ReadOwner|QFile::WriteOwner|QFile::ExeOwner|QFile::ReadGroup|QFile::ExeGroup|QFile::ReadOther|QFile::ExeOther))
    {
        qDebug("Something wrong!");
    }
 
 
    if(!myfile.open(QIODevice::WriteOnly | QIODevice::Text))
        return;
    QTextStream out(&myfile);
    out << preview;
    myfile.close();

---

But it doesnt work. So i guess it is not beacause the ORed statement. Could you please show me how?
I read the Qt help, but couldnt find any thing could help.
Thank you very much.

Where exactly is it failing? is it prematurely returning or are you getting your qdebug() message saying something is wrong?

Ok. this problem was solved. thank you very much. A friend of mine tell me the wrong in my code. just put the if statement below the open file command. Thanks.
