Customizing a QSlider in a style subclass

xtraction

Hello,

I am making a custom style subclassing from one of Qt's style classes (QMacStyle) and I am trying to first of all, make the sliders that I use different. For this I want to change the slider handle to be an image I have to give it a different look.

What I have tried so far is doing something like this:

@
void CustomStyle::drawComplexControl(ComplexControl cc, const QStyleOptionComplex *opt, QPainter p, const QWidget w) const
{
if(cc == CC_Slider)
{
const QSlider slider = static_cast< const QSlider>(w);
if(slider->orientation() == Qt::Horizontal){
drawHSlider(SC_SliderHandle, opt, p);
}
}

else
    return QMacStyle::drawComplexControl(cc, opt, p, w);

}

...

void CustomStyle::drawHSlider(SubControl handle, const QStyleOptionComplex *option, QPainter *painter) const
{
if(handle == SC_SliderHandle){
QPixmap fader(":/images/hfader");
QRect handleRect = subControlRect(CC_Slider, option, handle);

    painter->save();
    painter->setRenderHint(QPainter::Antialiasing);
    painter->drawPixmap(handleRect, fader);
    painter->restore();
}

}

But I'm kinda lost on how to draw the image to the handle of the slider and be able to move the slider like usual. Any help I would really appreciate. Thanks!

Wouldn't it be easier to use a style sheet instead? Perhaps something like:

@
QSlider::handle {image:url(:/images/hfacer) }
