Did you try to use QSS's opacity property?

[wagmare]

u mean setWindowOpacity() ..?
yes i did that .. its making the whole slider transparent ..

No, I mean Qt Style Sheet's opacity (http://qt-project.org/doc/qt-4.7/stylesheet-reference.html#id-6a4711aa-0d3e-45f9-8686-165873c5c349).

QWidget *wid = new QWidget;


QPalette palette ;
palette.setBrush(QPalette::Background, Qt::transparent);
wid->setPalette(palette);

wid->setAutoFillBackground(false);

theSlider = new QSlider(wid);

theSlider->setStyleSheet("background-color:transparent");

graphicsProxyItem->setWidget(wid);
