## @detail MainFrame主界面窗口类
class MainFrame(wx.Frame):
def __init__(self):
#重新定向wxpython的输出输入和错误输出到系统标准输入输出
sys.stdin = sys.__stdin__
sys.stdout = sys.__stdout__
sys.stderr = sys.__stderr__
wx.Frame.__init__(self, None, wx.ID_ANY,  'Ultimate list ctrl demo', pos=wx.DefaultPosition,
size=(800, 600), style=wx.DEFAULT_FRAME_STYLE)
self.CreateStatusBar()

panel = wx.Panel(self, -1)
box = wx.FlexGridSizer(10, 2, 5, 5)

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。
