         border-color: rgba(255, 255, 255, 0);");

2.设置窗体背景与透明

QWidget *pWidget->setStyleSheet("QWidget#appState{background-image:url(:/new/prefix/image/mainUI/down.png);background-color:rgba(255, 255, 255, 0);border-style: solid;border-width: 0px;\
           border-color: rgba(255, 255, 255, 0);}");

  his->setMask(bmap);

QPixmap maxPix = style()->standardPixmap(QStyle::SP_TitleBarMaxButton);
 QPixmap restorePix = style()->standardPixmap(QStyle::SP_TitleBarNormalButton);
