Erstmal absoluter Anfänger mit wxPython.
Ich versuche eine Minianwendung zue rstellen, bei der eine Datei (hier mp3) per wx.Dialog selktiert wird, danach soll dann diese datei bei
Drücken den Buttons Play mit dem externen Linuxprogarmm mpg321 abgespeilt werden (Befehl lautet mpg321 meinsong.mp3).

# create menu
menubar = wx.MenuBar()
#main menus
mnuFile = wx.Menu()
mnuData = wx.Menu()
menubar.Append(mnuFile,"&File")
menubar.Append(mnuData,"&Data")
#submenus
m_Open = mnuFile.Append(-1,"&Open")
mnuFile.AppendSeparator()
m_Exit = mnuFile.Append(-1,"&Exit")
m_Play = mnuData.Append(-1,"&Play")
# attach menu to frame
frame.SetMenuBar(menubar)
#bind menu events to procedures
frame.Bind(wx.EVT_MENU, OnExit, m_Exit)
frame.Bind(wx.EVT_MENU, OnOpen, m_Open)
frame.Bind(wx.EVT_MENU, OnPlay, m_Play)

dlg = wx.FileDialog(None, "Choose a file", os.getcwd(), "","*.*", wx.OPEN)
dlg.ShowModal()
filename=dlg.GetPath()
Fname = filename
dlg.Destroy()
textbox.write(Fname)
print Fname
def OnPlay(event):
# play mp3
befehl = "mpg321 %s" %(filename,)
process = subprocess.Popen(befehl , shell=True, stdout=subprocess.PIPE)

# create frame
frame = wx.Frame(None, title="PLOTTER", pos=(350,300))
create_menu(frame)
# editor textbox for date
textbox=wx.TextCtrl(frame, style = wx.TE_MULTILINE)
# show frame and run event loop
frame.Show()
app.MainLoop()Was muß ich machen damit meinsong.mp3 (hier im Beispiel als Fname in ein TextCtrl geschrieben) nach onOpen weiterverarbeitet werden kann?

P.S.
Das Ganze ist der Versuch, folgnede kleine Anwendung umzustricken, dort wird eine datendatei (2 Zahlenreihen) ausgewählt, der Inahlt der Datei in ein TextCtrl geschriebven, dann der Inahlt des TextCtrl ausgelesen, augbereitet und geplottet.
Ich möchte eben anstatt plotten, eine datei mot mpg321 abspielen.
