TypeError：方法'new_Dialog'中，'wxWindow *'類型的預期參數1

Question

我正在嘗試構建一個使用SSH瀏覽遠程位置文件的文件瀏覽器。我的GUI代碼不斷向我拋出一個或另一個錯誤，所以我甚至無法測試SSH部分（未包含在下面的代碼中）。我目前的錯誤似乎是我的類構造函數或我稱之爲[SSHFileDialog]的問題。如果有人能指出我在這裏出錯的地方，我將不勝感激。我對Python的知識是自學成才的，我最近纔開始用wxPython編寫GUI。

代碼：

import wx,os 

class SSHFileDialog(wx.Dialog): #, hostname = 'DefaultHost', username = 'DefaultUser', password = 'Password' 

    def __init__(self, parent): 
     super(SSHFileDialog, self).__init__(self, parent, -1, style = wx.DEFAULT_DIALOG_STYLE|wx.RESIZE_BORDER) 
     # self.hostname = kwargs['hostname'] 
     # self.username = kwargs['username'] 
     # self.password = kwargs['password'] 
     hostname = "Host" 
     username = "User" 
     self.SetMinSize((512,512)) 
     self.Centre() 
     self.SetTitle("Remote File Browser: Connection established to %s as %s"% (hostname,username)) 
     #print password 
     self.InitUI() 

    def InitUI(self): 

     currentDir = os.getcwd() #For Testing 
     fileAttr = [("Test","Test","Test","Test")] #Need to get file attributes from all files/folders in directory: Name, Type, Size, ModDate 

     pnl = wx.Panel(self) 
     vbox = wx.BoxSizer(wx.VERTICAL) 

     h_Dir_Box = wx.BoxSizer(wx.HORIZONTAL) 
     st_Dir = wx.StaticText(self, label = currentDir,style=wx.ALIGN_LEFT) 
     btn_Back = wx.Button(self,label = 'Back') 
     h_Dir_Box.Add(st_Dir,flag=wx.ALL, border = 5) 
     h_Dir_Box.Add(btn_Back) 


     stbox = wx.StaticBox(pnl, wx.ID_ANY, "Directory Contents") 
     stboxS = wx.StaticBoxSizer(stbox, orient = wx.HORIZONTAL) 
     list = wx.ListCtrl(stbox, style = wx.LC_REPORT|wx.LC_VRULES|wx.LC_SINGLE_SEL) 
     list.InsertColumn(0,'Filename',width = 175) 
     list.InsertColumn(1,'Type', width = 100) 
     list.InsertColumn(2,'Size', width = 75) 
     list.InsertColumn(3,'Date Modified',wx.LIST_FORMAT_RIGHT, 90) 

     for i in fileAttr: 
      index = list.InsertStringItem(len(fileAttr)+10,i[0]) 
      list.SetStringItem(index,1,i[1]) 
      list.SetStringItem(index,2,i[2]) 
      list.SetStringItem(index,3,i[3]) 

     pnl.SetSizer(stboxS) 


     h_Open_Box = wx.BoxSizer(wx.HORIZONTAL) 
     btn_Open = wx.Button(self, label = 'Open') 
     btn_Can = wx.Button(self, label = 'Cancel') 
     h_Open_Box.Add(btn_Open) 
     h_Open_Box.Add(btn_Can,flag = wx.LEFT,border=10) 


     vbox.Add(h_Dir_Box, flag=wx.ALL|wx.EXPAND, border = 10) 
     vbox.Add(pnl, proportion =1 , flag=wx.ALL|wx.EXPAND|wx.ALIGN_CENTER, border = 20) 
     vbox.Add(h_Open_Box, flag = wx.ALIGN_RIGHT) 

     self.SetSizer(vbox) 

     btn_Open.Bind(wx.EVT_BUTTON, self.OnClose) 
     btn_Can.Bind(wx.EVT_BUTTON, self.OnClose) 

    def OnClose(self,e): 
     self.Destroy() 


class TestGui(wx.Frame): 

    def __init__(self,*args,**kwargs): 
     super(TestGui,self).__init__(*args,**kwargs) 

     self.InitUI() 

    def InitUI(self): 

     menubar = wx.MenuBar() 
     fileMenu = wx.Menu() 
     openFileItem = fileMenu.Append(wx.ID_OPEN,'&Open') 
     fileMenu.AppendSeparator() 

     quitApp = fileMenu.Append(wx.ID_EXIT, "&Quit\tCtrl+Q") 

     menubar.Append(fileMenu, '&File') 

     self.SetMenuBar(menubar) 

     self.Bind(wx.EVT_MENU,self.OnQuit,quitApp) 
     self.Bind(wx.EVT_MENU,self.OnOpen,openFileItem) 

     self.SetSize((500,500)) 
     self.SetTitle('File Manager example') 
     self.Centre() 
     self.Show(True) 

    def OnQuit(self,e): 
     self.Close() 

    def OnOpen(self,e): 
     args = {'hostname':'Host','username':'user','password':'password'} 
     fileDialog = SSHFileDialog(None) 
     fileDialog.ShowModal() 
     fileDialog.Destroy() 

def main(): 
    app = wx.App() 
    TestGui(None) 
    app.MainLoop() 

if __name__ == '__main__': 
    main()

Answer 1

你很可能工作過的老教程

wx.Dialog.__init__(self,*args,**kwargs) #here you need self, as this does not pass self implicitly 

而

super(MyDialogClass,self).__init__(*args,**kwargs) # here self is passed implicitly (eg you do not pass self as the first arg) 

但是你應該小心一點與super和wxPython的IIRC有不從object這將導致MRO打破...（TBH它可能已經固定）

** TLDR繼承了一些基礎類; **

變化

super(SSHFileDialog, self).__init__(self, parent, -1, style = wx.DEFAULT_DIALOG_STYLE|wx.RESIZE_BORDER) 

到

super(SSHFileDialog, self).__init__(parent, -1, style = wx.DEFAULT_DIALOG_STYLE|wx.RESIZE_BORDER)

從評論回答您的其他問題

class SSHFileDialog(wx.Dialog): #, hostname = 'DefaultHost', username = 'DefaultUser', password = 'Password' 

    def __init__(self, parent,host,username,password): 
     self.ssh_thing = SSHClient(host,username,password) 
     super(SSHFileDialog, self).__init__(self, parent, -1, style = wx.DEFAULT_DIALOG_STYLE|wx.RESIZE_BORDER) 

Answer 2

你傳入一個額外的self到wx.Dialog.__init__。撥打super本質上是爲您創建綁定方法，因此您不需要再次通過self。

super(SSHFileDialog, self).__init__(parent, -1, style = wx.DEFAULT_DIALOG_STYLE|wx.RESIZE_BORDER)
