You cannot control that from Qt as it is not Qt drawing them in the end. However, you can use QPainter with the following methods to draw a custom title bar line on top of your widget:

void QPainter::setPen(const QColor & color)

void QPainter::setBrush(const QBrush & brush)

void QPainter::drawLine(const QLine & line)

You could check out the analog clock example in Qt for painting customization.

Do not forget about the Qt::FramelessWindowHint flag either.
