希望您需要遵循一般 的检测方法 。

bool IsOutOfDesktop(QWidget *w)
{
    QDesktopWidget *desktopWidget = QApplication::desktop();
    QRect screenRect = desktopWidget->screenGeometry(&w);
    QPoint topLeft = w.mapToGlobal(w.geometry().topLeft());
    QPoint bottomRight = w.mapToGlobal(w.geometry().bottomRight());

   if(!screenRect.contains(topLeft) || !screenRect.contains(bottomRight))
        return true;

   return false;
}
