Proper use of an InputDialog box - capture CANCEL click

[emp1953]

I have the following function that is a SIMPLE password input dialog.

It works except that I cannot capture and process the CANCEL button click.
When CANCEL is clicked I want the dialog box to close without doing anything.
I have the cancel variable for the button click return but cannot get it done.

Here's the function

int class::display_password_dialog()
{
     QString retarg;
     bool cancel;
 
     do
     {
           retarg = QInputDialot::gettext(0,"Password Entry", "Type Password, Press Ok: ",QLineEdit::Normal, "***", &cancel);
           std::cout <<"user entered"<< retarg.toStdString()<<std::endl;
           if(cancel)
           {
                std::cout<<"Cancel pressed"<<std::endl;
                return EXIT_FAILURE;
           }
     } while (retarg != "'");
     return EXIT_SUCCESS;
}

int class::display_password_dialog()
{
     QString retarg;
     bool cancel;

     do
     {
           retarg = QInputDialot::gettext(0,"Password Entry", "Type Password, Press Ok: ",QLineEdit::Normal, "***", &cancel);
           std::cout <<"user entered"<< retarg.toStdString()<<std::endl;
           if(cancel)
           {
                std::cout<<"Cancel pressed"<<std::endl;
                return EXIT_FAILURE;
           }
     } while (retarg != "'");
     return EXIT_SUCCESS;
}
