Hello,

You can put the progress bar in status bar if you are using a QMainWindow:

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    //class initialization
    //...
    m_progress = new QProgressBar;
    statusBar()->addPermanentWidget(m_progress);
    m_progress->hide();
    //...
}
    
    
void MainWindow::onProcessStarted()
{
    m_progress->show();
}

void MainWindow::onProcessFinished()
{
    m_progress->hide();
}

void MainWindow::onProgressValueChanged(int progressValue)
{
    m_progress->setValue(progressValue);
}

void MainWindow::onProgressMaxChanged(int progressMax)
{
    m_progress->setMaximum(progressMax);
}

If you want to show several progress bars at the same time, a list view of progress bars could be a better approach
