  I'll say it again: instead of making the window fully transparent, make it
  infinitesimally opaque so that it isn't transparent to mouse clicks.

I am completely shooting into the blue here, but in my case setting QGraphicsItem#setShapeMode() to the value 'QGraphicsPixmapItem::BoundingRectShape' helped.

Thanks for your suggestion. I think that would work nicely in the QGraphicsView. However, I am not using one. I am using standard QWidgets, which do not have a shape method.

Cheers,
Sean
