python通過wxPython打

 這篇文章主要介紹了python通過wxPython打開一個音頻文件並播放的方法,實例分析了wxPython操作音頻文件的技巧,具有一定參考借鑒價值,需要的朋友可以參考下

   

本文實例講述了python通過wxPython打開一個音頻文件並播放的方法。分享給大家供大家參考。具體如下：

這段代碼片段使用wx.lib.filebrowsebutton.FileBrowseButton控件打開一個wav文件，使用wx.Sound播放

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 import wx import wx.lib.filebrowsebutton class MyFrame(wx.Frame): def __init__(self, parent, mytitle, mysize): wx.Frame.__init__(self, parent, wx.ID_ANY, mytitle, size=mysize) self.SetBackgroundColour("green") panel = wx.Panel(self) # mask file browser to look for .wav sound files self.fbb = wx.lib.filebrowsebutton.FileBrowseButton(panel, labelText="Select a WAVE file:", fileMask="*.wav") self.play_button = wx.Button(panel, wx.ID_ANY, ">> Play") self.play_button.Bind(wx.EVT_BUTTON, self.onPlay) # setup the layout with sizers hsizer = wx.BoxSizer(wx.HORIZONTAL) hsizer.Add(self.fbb, 1, wx.ALIGN_CENTER_VERTICAL) hsizer.Add(self.play_button, 0, wx.ALIGN_CENTER_VERTICAL) # create a border space border = wx.BoxSizer(wx.VERTICAL) border.Add(hsizer, 0, wx.EXPAND|wx.ALL, 10) panel.SetSizer(border) def onPlay(self, evt): filename = self.fbb.GetValue() self.sound = wx.Sound(filename) # error handling ... if self.sound.IsOk(): self.sound.Play(wx.SOUND_ASYNC) else: wx.MessageBox("Missing or invalid sound file", "Error") app = wx.App(0) # create a MyFrame instance and show the frame mytitle = "wx.lib.filebrowsebutton and wx.Sound" width = 600 height = 90 MyFrame(None, mytitle, (width, height)).Show() app.MainLoop()

希望本文所述對大家的Python程序設計有所幫助。
