hi there,

I gotta draw a rounded rectangle n fit MultiSlider widget inside of it. I was told I'd be able to present it with setmas().
here's the code, please add the required code for me.

Qt Code: 
  1. void QtMultiSlider::paintEvent(QPaintEvent * event)
  2. {
  3.     Q_UNUSED(event)
  4.  
  5.     if (!isVisible())
  6.         return;
  7.  
  8.     QPainter painter;
  9.     painter.begin(this);
  10.  
  11.     painter.setPen(Qt::blue);
  12.     painter.setBrush(Qt::SolidPattern);
  13.     QRect rect(50, 50, 240, 100);
  14.     painter.setRenderHint(QPainter::Antialiasing, true);
  15.     painter.drawRoundedRect(rect, 25, 25, Qt::RelativeSize);
  16.  
  17.     int spacing = 30;
  18.     int labelHeight = 0;
  19.  
  20.     int valueBarWidth = 300;
  21.  
  22.     // Calculating the maximum string size
  23.  
  24.     int valueBarX = spacing;
  25.     int valueBarBottomY = 0;
  26.  
  27.     QSizeF originalSize = m_rendererValueBarTop->defaultSize();
  28.     QSizeF targetSize = originalSize;
  29.     targetSize.scale(QSizeF(valueBarWidth, originalSize.height()), Qt::KeepAspectRatio);
  30.     qreal scaleRatio = targetSize.width() /
  31.                        originalSize.width();
  32.  
  33.     QSize valueBarBottomSize = m_rendererValueBarBottom->defaultSize() * scaleRatio;
  34.  
  35.     valueBarBottomY = height() - labelHeight - 20
  36.                                - valueBarBottomSize.height();
  37.  
  38.     m_valueBarRightRect =    QRect(QPoint(valueBarX, 20),
  39.                               QSize(valueBarWidth, valueBarBottomY));
  40.  
  41.     m_rendererValueBar->render(&painter, m_valueBarRightRect);
  42.  
  43.     int filledPixels = ((double)value()) / maximum() * m_valueBarRightRect.height();
  44.     QRect filledRect = m_valueBarRightRect;
  45.     filledRect.setTop(filledRect.bottom() - filledPixels);
  46.     m_rendererValueBarFilled->render(&painter, filledRect);
  47.  
  48.  
  49.     painter.end();
  50.  
  51. }
