QSlider not showing over background image using stylesheet (RESOLVED)

[rcourtney]

QSlider has a PNG image for handle. Shows correctly. Don't need a groove image as
QFrame, for entire workspace, has the artwork. I see a black rectangle with the handle
over top of the background.

Other children of the frame (groupboxes, labels, etc) are showing correctly.

@#frame {
background-image: url(:/qml/file_1.png);
}@

QSlider::add-page {
color: rgba(0,0,0,0);
}
QSlider::sub-page {
color: rgba(0,0,0,0);
}
QSlider::handle {
image: url(:/qml/file_5.png);
}
QSlider::groove {
background-color: rgba(0, 0, 0, 0);
}

What am I missing?

EDIT: I forgot about centralWidget - Resolved

rgba(0, 0, 0, 0) should be written as rgba(0, 0, 0, 0%). However, it means full transparency which is probably not what you want.
