本文实例讲述了python通过wxPython打开一个音频文件并播放的方法。分享给大家供大家参考。具体如下：
这段代码片段使用wx.lib.filebrowsebutton.FileBrowseButton控件打开一个wav文件，使用wx.Sound播放
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()
希望本文所述对大家的Python程序设计有所帮助。
