4. QDial - loops

QDial - loops


  • Hello, I made a Program with just a basic QDial and a progressBar, I have included some code below. I'm just having a hard time with the loops, if that's what I should do? I have 0 as default, and 100 as maximum.. Thanks, =).

    @
    connect(ui->dial, SIGNAL(sliderMoved(int)), ui->progressBar, SLOT(update()));

    // Should I add a separate update function? Program1::update()
    {
    // Very confused here, the person who has been helping me hasn't been around, =/.
    }
    for (i-0; i<=100; i++); // Not sure if I should use i<100 or i<=100;
    {
    // This is where I'm stuck at..
    }
    @

    Edit: replaced code tags for @ tags, as they work better in the forum section; Andre

  • Hi Richard,

    if you want the value of the dial in the progress bar, you need another connect statement:

    @
    connect(ui->dial, SIGNAL(sliderMoved(int)), ui->progressBar, SLOT(setValue(int)));
    @

  • What exactly are you wanting to do in the loop?
