Answer 1

QGraphicsView inherits from QFrame. Use the setFrameStyle method and the lineWidth property to change the frame appearance.

You can also use the stylesheet to customize the look (including the borders) of a QFrame, see the stylesheet doc.

To make your widget look flat just add this CSS : border: 0px
