本文实例讲述了python使用wxpython打开并播放wav文件的方法。分享给大家供大家参考。具体实现方法如下：
''' wx_lib_filebrowsebutton_sound.pyselect a sound file and play itwx.lib.filebrowsebutton.filebrowsebutton(parent, labeltext, filemask)(combines wx.textctrl and wxfiledialog widgets)wx.sound(filename, isresource=false)tested with python27 and wxpython291 by vegaseat 25jul2013'''import wximport wx.lib.filebrowsebuttonclass 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 framemytitle = wx.lib.filebrowsebutton and wx.soundwidth = 600height = 90myframe(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。
