Showing negative values of axis on the progress bar

[deleted286]

Hi everyone. I have 8 different progress bar. In the code below, im showing the positive values of my array. I want to display negative values also. How can i do it?
When i put else and write the other progress bar on gui, it didnt work true

    ```

if(dizi[1] > 0  || dizi[2] > 0 || dizi[3] > 0  || dizi[4] > 0)
        {
            ui->progressBarAx->setValue(dizi[1]);
            ui->progressBarAy->setValue(dizi[2]);
            ui->progressBarBx->setValue(dizi[3]);
            ui->progressBarBy->setValue(dizi[4]);

        }

@suslucoder well, have you set your minimum of the progress bar beforehand to a value, that is below 0?

@J-Hilk It should be between -500 and 0, so
can i put this

     ```

ui->progressBarAxNeg->setMinimum(-500);
         ui->progressBarAxNeg->setMaximum(0);

can i put this

AFAIK yes, why don't you try it ?

@J-Hilk It doesnt work true still.

@suslucoder ?

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QProgressBar pbar;

    pbar.setRange( -50,50);
    pbar.setValue(-50);
    pbar.setOrientation(Qt::Horizontal);

    pbar.show();
    pbar.resize(200,50);

    QTimer t;
    QObject::connect(&t, &QTimer::timeout, [&t, &pbar]()->void{
        auto nextValue = pbar.value()+1;
        if(nextValue > pbar.maximum()){
            t.stop();
            return;
        }
        pbar.setValue(nextValue);
    });
    t.start(500);

    return  app.exec();
}

Show your code.

if(dizi[1] > 0 || dizi[2] > 0 || dizi[3] > 0 || dizi[4] > 0)

If this is from your code, then it will only update the progress bars if at least one of the 4 values is greater 0. Furthermore, if your array/vector dizi has 4 entries you need to use indices 0 through 3.

@SimonSchroeder I want to update my progress bar, if one of these values greater than 0. For example if the dizi[1] > 0, update.

I dont want to see dizi[0]. Because of it i started from 1
