如何在wxPython的打開文件對話框中選擇沒有任何擴展名的文件？

Question

使用sampleTextEditor中的這個例子，當瀏覽時，我可以看到，我可以打開任何帶擴展名的文件（。）。如何打開沒有擴展名的文件？

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 

Answer 1

變化*.*到*

所以現在整個文件名是外卡下，沒有點需要
