stylesheets and trasparent background

[godlike_panos]

I have a style sheet that practically overrides everything. In a certain situation I have a QGroupBox with a gradient background. Inside that QGroupBox I place a QScrollArea. The problem is that the QScrollArea cannot be transparent. I've tried to set all the backgrounds to none but it takes the default QWidget background.

QScrollArea {
	background: none;
}
 
QScrollArea > QWidget {
	background: none;
}
 
QScrollArea > QWidget > QWidget {
	background: none;
}

QScrollArea {
	background: none;
}

QScrollArea > QWidget {
	background: none;
}

QScrollArea > QWidget > QWidget {
	background: none;
}

Any ideas?
