Setting colour on qslider

Hi,

I Am trying to set colour for half of slider which is vertical,but I Am not able to do.

Can you please suggest how to do????

Thanks in Advance......

You mean something like a red upper half and a green lower half?

Exactly....but I want to set only lowerhalf with red colour....

You can fake it with the border image:

Code:

---

#include <QApplication>
#include <QSlider>
 
int main(int argc, char **argv)
{
    QApplication app(argc, argv);
 
    QSlider slider(Qt::Vertical);
    slider.resize(40, 300);
    slider.setStyleSheet(" QSlider { border-image: url('bg.png') 0 0 0 0 stretch stretch; } " );
    slider.show();
    return app.exec();
}

with a file bg.png that is an 18x18 pixel square with a transparent upper half, and coloured lower half.
