    Description

      According to the API doc, passing Qt::WA_X11NetWmWindowTypes to QWidget::setAttribute() should set proper NETWM states when in X11. This used to work in Qt 4.8, but it has no effect in Qt5 when I'm using XCB backend.
      I checked the source code of Qt 5 and it seems that code related to this feature is actually removed.
      This feature need to be implemented in the xcb backend.
