python - TypeError: __init__() は少なくとも 3 つの引数を取ります (1 つ指定)

Question

これはGUIの私のコードです:

import wx
import os.path


class MainWindow(wx.Frame):
    #def __init__(self, filename=''):
        #super(MainWindow, self).__init__(None, size=(800,600))
    def __init__(self, parent, title, *args, **kwargs):
        super(MainWindow,self).__init__(parent, title = title, size = (800,600))
        wx.Frame.__init__ ( self, parent, id = wx.ID_ANY, title = wx.EmptyString, pos =  wx.DefaultPosition, size = wx.Size( 800,608 ), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL )
        self.SetSizeHintsSz( wx.DefaultSize, wx.DefaultSize )
        grid = wx.GridSizer( 2, 2, 0, 0 )

        self.filename = filename
        self.dirname = '.'
        self.CreateInteriorWindowComponents()
        self.CreateExteriorWindowComponents()

    def CreateInteriorWindowComponents(self):


        staticbox = wx.StaticBoxSizer( wx.StaticBox( self, wx.ID_ANY, u"Enter text" ), wx.VERTICAL )
        staticbox.Add( self.m_textCtrl1, 0, wx.ALL|wx.EXPAND, 5 )
        self.m_textCtrl1 = wx.TextCtrl( self, wx.ID_ANY, wx.EmptyString, wx.DefaultPosition, wx.Size( -1,250 ), wx.TE_MULTILINE)
        self.m_textCtrl1.SetMaxLength(10000)

        self.Submit = wx.Button( self, wx.ID_ANY, u"Submit", wx.DefaultPosition, wx.DefaultSize, 0 )
        staticbox.Add( self.Submit, 0, wx.ALL, 5 )

    def CreateExteriorWindowComponents(self):
        ''' Create "exterior" window components, such as menu and status
            bar. '''
        self.CreateMenu()
        self.CreateStatusBar()
        self.SetTitle()

    def CreateMenu(self):
        fileMenu = wx.Menu()
        for id, label, helpText, handler in \
            [(wx.ID_ABOUT, '&About', 'Storyteller 1.0 -',
                self.OnAbout),
             (wx.ID_OPEN, '&Open', 'Open a new file', self.OnOpen),
             (wx.ID_SAVE, '&Save', 'Save the current file', self.OnSave),
             (wx.ID_SAVEAS, 'Save &As', 'Save the file under a different name',
                self.OnSaveAs),
             (None, None, None, None),
             (wx.ID_EXIT, 'E&xit', 'Terminate the program', self.OnExit)]:
            if id == None:
                fileMenu.AppendSeparator()
            else:
                item = fileMenu.Append(id, label, helpText)
                self.Bind(wx.EVT_MENU, handler, item)

        menuBar = wx.MenuBar()
        menuBar.Append(fileMenu, '&File') # Add the fileMenu to the MenuBar
        self.SetMenuBar(menuBar)  # Add the menuBar to the Frame

    def SetTitle(self):
        # MainWindow.SetTitle overrides wx.Frame.SetTitle, so we have to
        # call it using super:
        super(MainWindow, self).SetTitle('Editor %s'%self.filename)


    # Helper methods:

    def defaultFileDialogOptions(self):
        ''' Return a dictionary with file dialog options that can be
            used in both the save file dialog as well as in the open
            file dialog. '''
        return dict(message='Choose a file', defaultDir=self.dirname,
                    wildcard='*.*')

    def askUserForFilename(self, **dialogOptions):
        dialog = wx.FileDialog(self, **dialogOptions)
        if dialog.ShowModal() == wx.ID_OK:
            userProvidedFilename = True
            self.filename = dialog.GetFilename()
            self.dirname = dialog.GetDirectory()
            self.SetTitle() # Update the window title with the new filename
        else:
            userProvidedFilename = False
        dialog.Destroy()
        return userProvidedFilename

    # Event handlers:

    def OnAbout(self, event):
        dialog = wx.MessageDialog(self, 'A sample editor\n'
            'in wxPython', 'About Sample Editor', wx.OK)
        dialog.ShowModal()
        dialog.Destroy()

    def OnExit(self, event):
        self.Close()  # Close the main window.

    def OnSave(self, event):
        textfile = open(os.path.join(self.dirname, self.filename), 'w')
        textfile.write(self.control.GetValue())
        textfile.close()

    def OnOpen(self, event):
        if self.askUserForFilename(style=wx.OPEN,
                                   **self.defaultFileDialogOptions()):
            textfile = open(os.path.join(self.dirname, self.filename), 'r')
            self.control.SetValue(textfile.read())
            textfile.close()

    def OnSaveAs(self, event):
        if self.askUserForFilename(defaultFile=self.filename, style=wx.SAVE,
                                   **self.defaultFileDialogOptions()):
            self.OnSave(event)


app = wx.App()
frame = MainWindow()
frame.Show()
app.MainLoop()

私は取得しています

TypeError:: __init__() takes at least 3 arguments (1 given)

最後から3行目にframe = MainWindow()

パラメータリストが一致していることを確認するにはどうすればよいですか? 私は自分自身、親、または何かを渡すことに少し混乱していると思います。

助けてください！

EDIT：@mhlester：あなたが提案した変更を加えましたが、今は別のエラーがあります：

TypeError: in method 'new_Frame', expected argument 1 of type 'wxWindow *'

実際、これは完全なテキストがどのように見えるかです:

 Traceback (most recent call last):
  File "C:\Users\BT\Desktop\BEt\gui2.py", line 115, in <module>
    frame = MainWindow(app,'Storyteller')
  File "C:\Users\BT\Desktop\BE\gui2.py", line 9, in __init__
    super(MainWindow,self).__init__(parent, title = title, size = (800,600))
  File "C:\Python27\lib\site-packages\wx-3.0-msw\wx\_windows.py", line 580, in __init__
    _windows_.Frame_swiginit(self,_windows_.new_Frame(*args, **kwargs))
TypeError: in method 'new_Frame', expected argument 1 of type 'wxWindow *'

Answer 1

3 つの値を受け入れるように init を設定し、何も渡さないようにします。このフレームはトップ レベルのウィンドウになるため、None の親とある種のタイトル文字列を渡すことができます。

frame = MainWindow(None, "test")

次の問題は、スーパーと通常の両方の初期化ルーチンを使用しようとすることです。どちらか一方のみを使用できますが、両方を使用することはできません! スーパーの方は短いのでそのままにして、後者はコメントアウトしました。「filename」が明らかに定義されていないため、 self.filenameも空の文字列に変更し、コードが不完全であるため、他のウィジェットを構築するための呼び出しをコメントアウトしました。

Answer 2

MainWindow宣言から：

def __init__(self, parent, title, *args, **kwargs):

selfクラスをインスタンス化すると自動的に渡されますが、呼び出しに渡す必要がありparentます。titleMainWindow()

frame = MainWindow(app, 'Window Title') # i'm not sure if app is right for parent, but i assume it is

*argsandは無視してかまいません。機能を**kwargs読み進めると、__init__それらはまったく使用されないためです...
