        button = wx.Button(panel, -1, 'Add')
        box.Add(button, 0, wx.ALIGN_CENTRE)
        button.Bind(wx.EVT_BUTTON, self.__OnAddClicked)
        
        self.listCtrls = ULC.UltimateListCtrl(panel, -1, size =(200, 100), style = ULC.ULC_MASK_TYPE, agwStyle = ULC.ULC_REPORT|ULC.ULC_HAS_VARIABLE_ROW_HEIGHT|ULC.ULC_NO_FULL_ROW_SELECT)
        self.listCtrls.InsertColumn(0, 'Name', ULC.ULC_FORMAT_CENTRE)
        self.listCtrls.InsertColumn(1, 'Selection', ULC.ULC_FORMAT_CENTRE)
        box.Add(self.listCtrls, 0, wx.ALIGN_CENTRE)
        panel.SetSizerAndFit(box)
    
    def __OnAddClicked(self, event):
        index = self.listCtrls.InsertStringItem(sys.maxint, 'name 1')
        
        panel = wx.Panel(self.listCtrls, -1)
        sizer = wx.BoxSizer(wx.VERTICAL)
        cbb = wx.ComboBox(panel, -1, value = '1', choices = ['1', '2', '3', '4', '5'], style = wx.CB_DROPDOWN|wx.TE_PROCESS_ENTER)
        sizer.Add(cbb, 1, wx.EXPAND)
        panel.SetSizer(sizer)
        
        #cbb =  wx.Button(self.listCtrls, -1, 'Add')
        cbb.Bind(wx.EVT_PAINT, self.__OnPaint)
        self.listCtrls.SetItemWindow(index, 1, panel, expand = True)
        self.listCtrls.Update()
    
    def __OnPaint(self, event):
        event.Skip() 

        
    
    
        
              
        
    
        

解决方法如代码中，SetItemWindow()，添加control到列中的时候，可以先用wx.Panel做位其父控件。这样control不会被一直重绘。我在项目中用到ComboBox时候，遇到了这个情况。其他控件暂时没有遇到过。wxPython 还是有许多问题的。
