You could use a QRubberBand to setup the line and once you release it add the QGraphicsLineItem to your scene.

Hi, well the case is that I was trying to build mumble with QtCreator and I couldn't get it to build the application, I thought why not set it using stylesheet. I'll have to fight with Qt again, thanks for your reply.

@onek24 For the benefit of anyone finding this post, I found a much simpler solution for attaching information to a menu action : void QAction::setData(const QVariant & userData) QVariant QAction::data() const I currently prefer it over the much heavier solution of implementing a custom QAction class.

I would try on this snippet , Hope it works well.

@Korchkidu For me it works with both.
