QDialog - how to stop hide on "ESC"?

I have a modal dialog box that I need to be displayed until I'm finished some processing. However the user can close/hide the dialog by pressing the "ESC" key. How can I override this default behavior in QDialog so I can stop it from doing this?

If the user presses the Esc key in a dialog, QDialog::reject() will be called. You can reimplement that function to do nothing under certain circumstances:

Code:

---

void MyDialog::reject()
{
    if (itsOkToClose)
    {
        QDialog::reject();
    }
}

Great. That worked.
