I think there are not many ways to do this. I imagine you will have to create a frame-less widget and use transparency to 'cut out' the bits you do not want.

Do you want to change the shape of the widget or just the image on the widget?

There's no three line solution I can see. Derive from the closest widget and provide your own paintEvent(). Essentially you want a perspective transformation applied to your image. You may also need handle mouse events to define a clickable area if that's a requirement.

Bear in mind that the Qt layout system will still consider the widget a rectangular area.
