        self.testMedia = wx.media.MediaCtrl(self,
                                            szBackend=wx.media.MEDIABACKEND_WMP10,
                                            style=wx.SIMPLE_BORDER,)
        self.MOVE = ('6.mpg', '7.wmv','1.avi','4.jpg')
        self.testMedia.Load(self.MOVE[0])
        self.testMedia.Bind(wx.media.EVT_MEDIA_LOADED, self.play, self.testMedia)
        self.testMedia.Bind(wx.media.EVT_MEDIA_STATECHANGED, self.play2, self.testMedia)
    def play(self, e):
        self.testMedia.GetBestSize()
        self.testMedia.Play()
    def play2(self, e): 
        if self.testMedia.GetState() == wx.media.MEDIASTATE_STOPPED:
            for i in range(len(self.MOVE)):
                if i == 1:
                    self.testMedia.Load(self.MOVE[1])
                elif i == 2:
                    self.testMedia.Load(self.MOVE[2])
                elif i == 3:
                    self.testMedia.Load(self.MOVE[3])                   
if __name__ == '__main__':
    app = wx.App()
    Fream = TestPanel()
    Fream.Show(True)
    app.MainLoop()

请帮我下一个自己。移动[0] -> [1] -> [2] -> [3] -> [0] ....循环播放我不知道下一步该怎么做...在哪里可以看到wx.media教程和示例代码？

Answer 1

您不应该使用wx.media.EVT_MEDIA_STATECHANGED它可能会因媒体完成以外的其他原因而更改。请改用wx.media.EVT_MEDIA_FINISHED。
您可以使用简单的计数器进行循环。
在状态"已完成"上，使用索引执行下一次加载，代码应该可以工作。
我注意到您加载的最后一项是.jpg。不知道这是什么意思"完成"！
