                if i == 1:
                    self.testMedia.Load(self.MOVE[1])
                elif i == 2:
                    self.testMedia.Load(self.MOVE[2])
                elif i == 3:

帮助我plz下一个self.MOVE [0] - ＆gt; [1] - ＆gt; [2] - ＆gt; [3] - ＆gt; [0] ....循环播放我不知道下一步该做什么......哪里可以看到wx.media教程和exmple代码？

Answer 1

你不应该使用wx.media.EVT_MEDIA_STATECHANGED它可能因媒体完成之外的其他原因而改变。请改用wx.media.EVT_MEDIA_FINISHED 你可以使用一个简单的计数器循环在状态完成时使用索引执行下一个Load，代码应该起作用我注意到你加载的最后一项是.jpg。不确定这是什么意思＆＃34;完成＆＃34;！

        print "Playing:",self.MOVE[self.Mrange]
        self.testMedia.Play()

    def play2(self, e): 
        self.testMedia.Stop()
        self.Mrange += 1
        print self.Mrange
        if self.Mrange > len(self.MOVE) -1:
            self.Mrange = 0
        self.testMedia.Load(self.MOVE[self.Mrange])

if __name__ == '__main__':
    app = wx.App()
    Fream = TestPanel()
    Fream.Show(True)
    app.MainLoop()

python3 wx.media视频和图像显示？
