How to take advantage of Per-moniter DPI awareness feature in Qt5?

  • Qt5.4 now support Per-moniter DPI awareness, so what should I do to make my application auto adjusting different monitor DPI? How does Qt adjust fixed dimensions according to different DPI(like scrollbar width in fusion style)?(scalable dimensions can auto adjust via layout and factors*widget size) Will Qt automaticly resize my window when I drag it to a different DPI monitor?
