我試圖將EVT_TASKBAR_RIGHT_UP事件附加到從wx.TaskBarIcon派生的使用self.Bind(wx.EVT_TASKBAR_RIGHT_UP, self.OnTaskBarRight)的自定義類中的函數。這是該類的功能init。然而,在翻譯時遇到它,它給了我這樣的:在wx.TaskBarIcon派生類中綁定事件處理程序

Traceback (most recent call last): 
File "serverindicator.py", line 145, in <module> 
    tbicon = tbicon() 
File "serverindicator.py", line 125, in __init__ 
    self.Bind(wx.EVT_TASKBAR_RIGHT_UP, self.OnTaskBarRight) 
File "/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode/wx/_core.py", line 3918, in Bind 
    event.Bind(self, id, id2, handler)    
File "/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode/wx/_core.py", line 3992, in Bind 
    target.Connect(id1, id2, et, function) 
File "/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode/wx/_core.py", line 3875, in Connect 
    return _core_.EvtHandler_Connect(*args, **kwargs) 
TypeError: in method 'EvtHandler_Connect', expected argument 1 of type 'wxEvtHandler *' 

至於我可以告訴大家,這是說wx.EVT_TASKBAR_RIGHT_UP不是一個事件處理程序類型,這是我想的那樣。這與我正在使用它的課程有關嗎? 下面是相關位:

class tbicon(wx.TaskBarIcon): 
    def __init__(self): 
     icon = wx.Icon("red-circle.png", wx.BITMAP_TYPE_PNG) 
     self.SetIcon(icon, "") 
     self.Bind(wx.EVT_TASKBAR_RIGHT_UP, self.OnTaskBarRight) 

    def OnTaskBarRight(self, event): 
     ID_SETTINGS = wx.NewId() 
     ID_EXIT = wx.NewId() 
     self.rightmenu = wx.Menu(self, wx.ID_ANY) 
     settingsMenuItem = rightmenu.Append(ID_SETTINGS, "Settings") 
     exitMenuItem = rightmenu.Append(ID_EXIT, "Exit") 
     wx.EVT_MENU(self, ID_SETTINGS, settingswindow.Show(True)) 
     wx.EVT_MENU(self, ID_EXIT, self.OnExitClicked) 
     self.PopupMenu(self.rightmenu, event.GetPoint()) 
     self.rightmenu.Destroy() 

    def OnExitClicked(self, event): 
     serverindicator.Destroy() 

謝謝!

如果您覆蓋小部件的__init__方法,則需要調用父類的__init__方法。添加

super(tbicon, self).__init__() 

到您的__init__
