QSlider in Windows Volume Mixer Style

[Megamouse]

Hi guys,

Does someone have a cool solution to creating a Windows Volume Mixer Style QSlider?

It would be nice if it's something I can simply copy into the QtCreator stylesheet field.

Thanks in Advance,
Megamouse

Edit: It doesn't have to be exactly the same. Just the triangular background would be enough already

@Megamouse
you just need to subclass QSlider, and override its paintEvent() and draw the triangle-like shape within it.

I don't think that with stylesheets only this is achievable on QSlider (directly).

I really don't know how it will look like, but generally you can do something like this:

void MySlider::paintEvent(QPaintEvent *)
{
    QPainter p(this);
    QStyleOptionSlider opt;
    initStyleOption(&opt);

    // draw rectangle
    QPainterPath path;
       path.moveTo( opt.rect.bottomLeft() );
       path.lineTo( opt.rect.topRight() );
       path.lineTo( opt.rect.topLeft() );
       path.lineTo( opt.rect.bottomLeft() );
       path.closeSubpath();
   p.saveState();
      p.setPen( Qt::NoPen );
      p.setBrush( QBrush(Qt::lightGray) );
      p.drawPath(path);
   p.restoreState();

    // draw slider
    opt.subControls = QStyle::SC_SliderGroove | QStyle::SC_SliderHandle;
    if (d->tickPosition != NoTicks)
        opt.subControls |= QStyle::SC_SliderTickmarks;
    if ( isSliderDown() ) {
        opt.activeSubControls = isSliderDown();
        opt.state |= QStyle::State_Sunken;
    } else {
        opt.activeSubControls = d->hoverControl;
    }

    style()->drawComplexControl(QStyle::CC_Slider, &opt, &p, this);
}

Maybe the triangle coordinates need some more adjustments.
