How to adjust the size of widgets added to a QToolBar?

[fisyher84]

I have added a slider inside a QToolBar using AddWidget() directly as follows:

m_PreviewFrameSlider = new QSlider();
m_PreviewFrameSlider->setRange(0, 1000);
m_PreviewFrameSlider->setOrientation(Qt::Horizontal);
 
ui->PreviewToolBar->addWidget(m_PreviewFrameSlider);

m_PreviewFrameSlider = new QSlider();
m_PreviewFrameSlider->setRange(0, 1000);
m_PreviewFrameSlider->setOrientation(Qt::Horizontal);
    
ui->PreviewToolBar->addWidget(m_PreviewFrameSlider);

To copy to clipboard, switch view to plain text mode 

The slider appears as expected but is a little too narrow (about 100 pix. I want to adjust the width of the slider to at least 300 pix. I could not find any methods that can do so. Can someone give me some tips on how to do so?

QWidget::setMinimumWidth() looks promising.
