Height by value on a Custom Progress Bar ?

[MathFurious]

Hi,

I want to create a flat progress bar with QPainter, I paint graphics with the fallowing code:

QPainter painter(this);
 
    // Bar Background
    painter.setBrush(QBrush(Qt::white));
    painter.setPen(Qt::NoPen);
    painter.drawRect(0, 0, m_width, this->height());
 
    // Bar Value
    painter.setBrush(QBrush(m_fillColor));
 
    if (m_value == 0)
    {
        return;
    }
 
    qDebug() << "Value: " << m_value;
    qDebug() << "Height: " << this->height();
 
    int heightValue = (this->height() / m_value);
 
    qDebug() << "HValue: " << heightValue;
 
    painter.drawRect(0, 0, m_width, heightValue);

QPainter painter(this);

    // Bar Background
    painter.setBrush(QBrush(Qt::white));
    painter.setPen(Qt::NoPen);
    painter.drawRect(0, 0, m_width, this->height());

    // Bar Value
    painter.setBrush(QBrush(m_fillColor));

    if (m_value == 0)
    {
        return;
    }

    qDebug() << "Value: " << m_value;
    qDebug() << "Height: " << this->height();

    int heightValue = (this->height() / m_value);

    qDebug() << "HValue: " << heightValue;

    painter.drawRect(0, 0, m_width, heightValue);

To copy to clipboard, switch view to plain text mode 

But I tried some calculation for set the height of the progress bar with the progress bar value but nothing works...

What it is "nothing works" ?

Sorry, I found how to do what I want, thank anyway for reply.

... and if you would post your solution others would probably be happy as well.

int heightValue = (int)qRound(((float)currentValue / maxProgressBarValue) * heightOfTheProgressBar);

int heightValue = (int)qRound(((float)currentValue / maxProgressBarValue) * heightOfTheProgressBar);

And I draw with QPainter a rectangle like that:

painter.drawRect(0, 0, 100, heightValue);

painter.drawRect(0, 0, 100, heightValue);
