Returning hex value of utf8 string

I wrote a very simple test code,which receive a utf8 string from QLineEdit and display it in messagebox:

Code:

---

QString txtString = ui->lineEdit->text();
    QString scndString = txtString.toUtf8();
    QMessageBox msgBox;
 
    msgBox.setText(scndString);
    msgBox.exec();

---

Know I want to display utf8 hex value of string instead of string itself, but when I try to do this :

Code:

---

QString txtString = ui->lineEdit->text();
    QString scndString = txtString.toLatin1.toutf8.toHex();
    QMessageBox msgBox;
 
    msgBox.setText(scndString);
    msgBox.exec();

---

I received this message:

Quote:

---

error: 'txtString.QString::toLatin1' does not have class type QString scndString = txtString.toLatin1.toutf8.toHex();

You don't convert it to Latin-1 and then to UTF-8. That doesn't work. You convert the QString (which is UTF-16) directly to UTF-8.

Code:

---

txtString.toUtf8().toHex()

---

You need the parentheses because toUtf8 is a method (a function which is a member of a class), not a variable. I haven't used QByteArray, but hopefully that'll work.
