CustomTreeCtrlポップアップメニューバインディングアサーションエラー

Question

私はPyScripterに見られるような何らかのプロジェクトエクスプローラを作成しています。問題は、ポップアップメニューを表示するために右クリックするとAssertionErrorが発生することです。何か案が？ありがとうございます。

class ProgramManager(wx.Panel): 
    def __init__(self, parent): 
    super(ProgramManager, self).__init__(parent, size = (300,500), style = wx.BORDER_NONE|wx.TB_TOP)

    self.ToolBar.AddTool2(ID_SAVE_PROGRAM_AS, 'Save a copy of project') 
    self.ToolBar.AddTool2(ID_CLOSE_PROGRAM, 'Close the program') 
    self.Layout.Add(self.ToolBar, flag = wx.EXPAND) 
    self.ToolBar.Realize() 

    ## Set the Tree 
    self.FilePath = '' 
    self.Tree = CT.CustomTreeCtrl(self) 
    self.Layout.Add(self.Tree, 1, wx.ALL|wx.EXPAND) 

    ## Bind Events 
    self.Bind(wx.EVT_CLOSE, self.OnClose, self)

    EvtObj = Event.GetItem() 
    EvtObjData = EvtObj.GetData() 
    if EvtObj.GetParent() == None:

    self.PopMenu.Bind(wx.EVT_MENU, self.OnMenu, self.PopMenu) 
    self.PopMenu.Destroy() 

    def OnMenu(self, Event): 
    pass 

エラーコードはここで遊ぶのがこの

ところで、私はPython2.7とwx2.8.12

を使用しています

通常、フレームまたは親にメニューを添付する必要があるため、バインドステートメントを次のように変更する必要があります。

self.Bind(wx.EVT_MENU, self.OnMenu, self.PopMenu) 

これでうまくいかない場合は、再生できる小さな実行可能なサンプルアプリケーションを作成してください。詳細については、http://wiki.wxpython.org/MakingSampleAppsを参照してください。
