-

i have borderless (no title bar) qwidget window qgraphicsview inside. i've overwritten mousepressevent , mousemoveevent move window on desktop, when press on qgraphicsview not works.

below, code of mousepressevent , mousemoveevent:

void widget::mousepressevent(qmouseevent *evt) {     oldpos = evt->globalpos(); }  void widget::mousemoveevent(qmouseevent *evt) {     const qpoint delta = evt->globalpos() - oldpos;     move(x() + delta.x(), y() + delta.y());     oldpos = evt->globalpos(); }

i overwritten same code:

void mousepressevent(qgraphicsscenemouseevent *evt); void mousemoveevent(qgraphicsscenemouseevent *evt);

i tried with:

setinteractive(false); setdragmode(scrollhanddrag);

but nothing!
