setText using a string read from file

Hi all, I hope this is an easy question. How do I go about solving this problem I have with setText

This is my code:

Code:

---

string line;
 
    ifstream myfile("example.txt");
    if (myfile.is_open()) // Checks to see whether myfile opens
        {
           getline(myfile, line);
           ui->QuestionBox->setText(line);
 
        } else ui->QuestionBox->setText("An error has occured!");

It keeps throwing up an error. Is this because setText is supposed to have a QString associated with it... if so how do i overcome this problem. C++ didn't confuse me until I started learning QT, now nothing seems to work :(

Thanks for your help

Try it, test it, ...
But I think you're on to something ;-)

Use a QString. See the documentation.

Then you still have things to learn. Qt doesn't change how you use C++, it's just a collection of classes. The only thing extra is an extra precompiler for the signals and slots.

Hi I have solved my problem now :)

Thanks for the help... I think. :/

It was very easy. I just converted the string to QString using

Code:

---

line.c_str()

---

Thanks very much :)

c_str() returns a QString?
