Media Player Translucent

[wuqingjun]

I have some confusion when using QtMultimedia to implement a simple player


setattribute WA_TranslucentBackground player window translucent ???

mediaPlay code :

class VideoPlayerWidget(QWidget):
    def __init__(self, parent=None):
        super(VideoPlayerWidget, self).__init__(parent)

        self._hide_show_interval = 2000
        self._initUi()

    def _initUi(self):
        self.mediaPlayer = QMediaPlayer(None, QMediaPlayer.VideoSurface)
        self._view = QVideoWidget()
        self._video_control_widget = VideoControlWidget()

        lay = QGridLayout()
        lay.addWidget(self._view, 0, 0, 2, 1)
        lay.addWidget(self._video_control_widget, 1, 0, 1, 1)
        lay.setContentsMargins(0, 0, 0, 0)

        self.setLayout(lay)
        # Set widget to contain window contents


        self.mediaPlayer.setVideoOutput(self._view)
        self.mediaPlayer.positionChanged.connect(self._video_control_widget.update_position)
        self.mediaPlayer.durationChanged.connect(self._video_control_widget.update_duration)
        # self.mediaPlayer.error.connect(self.handleError)

        self._video_control_widget.played.connect(self.init_play)
        self._video_control_widget.stoped.connect(self.mediaPlayer.stop)
        self._video_control_widget.seeked.connect(self.mediaPlayer.setPosition)
        self._video_control_widget.containsCursor.connect(self._set_remain_control_widget_visible)

        self._timer_init()

    def loading_media(self, filename):
        mediaContent = QMediaContent(QUrl.fromLocalFile(filename))
        self.mediaPlayer.setMedia(mediaContent)
        self._video_control_widget.setMedia(filename)
        self.init_play()
        return self

    def _timer_init(self):
        self._timer = QTimer()
        self._timer.setInterval(self._hide_show_interval)
        self._timer.timeout.connect(self._bottom_widget_toggled)

    def _bottom_widget_toggled(self):
        self._timer.stop()
        self._video_control_widget.setVisible(False)

    def _timer_start(self):
        self._video_control_widget.setVisible(True)
        self._timer.start()

    def enterEvent(self, e):
        self._timer_start()
        return super(VideoPlayerWidget, self).enterEvent(e)

    def mouseMoveEvent(self, e):
        if self._timer.isActive():
            self._timer.setInterval(self._hide_show_interval)
        else:
            self._timer_start()
        return super(VideoPlayerWidget, self).mouseMoveEvent(e)

    def leaveEvent(self, e):
        self._video_control_widget.setVisible(False)
        return super(VideoPlayerWidget, self).leaveEvent(e)



    def init_play(self):
        if self.mediaPlayer.mediaStatus == QMediaPlayer.NoMedia:
            pass
        elif self.mediaPlayer.state == QMediaPlayer.PlayingState:
            self.mediaPlayer.pause()
        else:
            self.mediaPlayer.play()

    def _set_remain_control_widget_visible(self, f):
        if f:
            self._timer.timeout.disconnect()
        else:
            self._timer.timeout.connect(self._bottom_widget_toggled)

I need to turn on the transparent display of the window, how do I need to do it ？？？
