        QtDeclarative.QDeclarativeView.__init__(self, parent)  
        self.setStyleSheet("background:transparent")
        self.setAttribute(QtCore.Qt.WA_TranslucentBackground)
        self.setWindowFlags(QtCore.Qt.FramelessWindowHint | QtCore.Qt.WindowStaysOnTopHint)
        self.setResizeMode(QtDeclarative.QDeclarativeView.SizeRootObjectToView)
        self.setSource(QtCore.QUrl("VIDEO_QML_GUI)
        self.setGeometry(0, 0, 1280, 720)
        self.Setup()
        self.rootObject = self.rootObject()

if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    video_ui = VideoApplication()
    video_ui.show()
    sys.exit(app.exec_())

USBVideo.qml은 Item컴포넌트를 사용해서 구현하였고 python코드에서 이부분이 창의 특성을 투명으로 설정한다.

self.setStyleSheet("background:transparent")
self.setAttribute(QtCore.Qt.WA_TranslucentBackground)
self.setWindowFlags(QtCore.Qt.FramelessWindowHint | QtCore.Qt.WindowStaysOnTopHint)

대략 이런 모습이 나온다.
