Ich hab ein kleines GUI erstellt. Das Ziel ist, dass man zuerst die Parameter eingibt (Duration, Interval, Jobfile) und danach per 'Start' Button den while loop startet. Dieser loop sollte sich dann per 'Stop' Button beenden lassen. Allerdings scheint aber der loop keine Eingaben zuzulassen, denn wenn Start gedrückt wurde ist alles andere blockiert.
Ich habe Python 2.5, wxPython 2.8.3, Eclipse 3.2.2, PyDev 1.3.2

sizer.Add(bt, pos=(1,1), span=(1,2), flag=wx.EXPAND)

def OnInit(self):
frame = MyFrame(parent=None, id=-1, title="Test GUI")
self.SetTopWindow(frame)
frame.Show(True)
return True
if __name__ == "__main__":
app = MyApp(0)
app.MainLoop()
Also, hat jemand eine Idee wie ich beim Klick auf den Stop Button aus dem 'endless' loop rauskomme? Ich brauche aber leider einen endless loop der nur auf eine Useraktion beendet werden soll.
