I've made a custom style based on the existing cleanlooks style. I've got almoast everything the way I want, only I can not change the scroll bar. At least not the way I would like it.

I have to scrollbar images, one for vertical and one for horizontal scrollbar. But when I try to add them the whole scroll bar get's that image instead of just the scrollbar slider.

This is the code where I drawComplexControl():
Qt Code: 
  1. void mediaArchiverStyle::drawComplexControl(ComplexControl control, const QStyleOptionComplex * option, QPainter * painter, const QWidget * widget) const
  2. {
  3.     switch (control) {
  4.     case CC_ScrollBar:
  5.     {
  6.       int delta = (option->state & State_MouseOver) ? 64 : 0;
  7.       QColor slightlyOpaqueBlack(100, 100, 100, 63);
  8.       QColor semiTransparentWhite(255, 255, 255, 127 + delta);
  9.       QColor semiTransparentBlack(10, 10, 10, 127 - delta);
  10.  
  11.       int x, y, width, height;
  12.       option->rect.getRect(&x, &y, &width, &height);
  13.  
  14.       QPainterPath roundRect = roundRectPath(option->rect);
  15.       int radius = qMin(width, height) / 2;
  16.  
  17.       QBrush brush;
  18.       bool darker;
  19.  
  20.       const QStyleOptionSlider *sliderOption = qstyleoption_cast<const QStyleOptionSlider *>(option);
  21.       if (sliderOption) {
  22.         if (sliderOption->orientation == Qt::Vertical)
  23.           brush = option->palette.light();
  24.         else
  25.           brush = option->palette.midlight();
  26.         darker = false;
  27.       }
  28.  
  29.       QStyleOptionSlider mySliderOption;
  30.       if (sliderOption) {
  31.         mySliderOption = *sliderOption;
  32.         if (mySliderOption.palette.currentColorGroup() != QPalette::Disabled) {
  33.           if (mySliderOption.state & (State_Enabled)) {
  34.             mySliderOption.palette.setBrush(QPalette::ButtonText,
  35.             mySliderOption.palette.brightText());
  36.           }
  37.         }
  38.       }
  39.       QCleanlooksStyle::drawComplexControl(control, &mySliderOption, painter, widget);
  40.  
  41.       painter->save();
  42.       painter->setRenderHint(QPainter::Antialiasing, true);
  43.       painter->fillPath(roundRect, brush);
  44.       if (darker)
  45.         painter->fillPath(roundRect, slightlyOpaqueBlack);
  46.  
  47.       int penWidth;
  48.       if (radius < 10)
  49.         penWidth = 3;
