									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()
