Hello, you meant future call? Hm it doesn't work
Here my small sample app:


import wx



class MyApp(wx.App):

    def OnInit(self):

        frame = wx.Frame(None, title="Test SetMark on Combobox")

        panel = wx.Panel(frame)

        b = wx.Button(panel)

        b.SetPosition ((0, 0))

        self.cb = wx.ComboBox(panel)

        self.cb.SetValue("Hello Combobox")

        b.SetPosition ((0, 30))

        b.Bind(wx.EVT_BUTTON, self.OnButton)

        frame.Show(True)

        return True



    def OnButton(self, evt):

        #self.cb.SetMark (2,5)

        #wx.CallAfter(self.cb.SetMark,2,5)

        wx.FutureCall(3000, self.cb.SetMark,2,5)

        evt.Skip()



app = MyApp(redirect=False)

app.MainLoop()
