I am trying to use a tkinter filedialog.askopenfilename() method to be able to select image files for a generator. I am setting it up within a class as that is what I found was the 'correct' method of doing so. As far as I know, this should be the correct format for calling this, though it just kind of a bodge of the few explanations I could find.

class Application(tk.Frame):
    def __init__(self, master=None):
        super().__init__(master)
        self.master = master
        self.pack()
        self.pickedfiletypes = (('png files', '*.png'), ('jpeg files', '*.jpeg'))
        self.create_widgets()

    def create_widgets(self):
        ...

        self.fileselect = tk.filedialog.askopenfilename(self,
                                    initialdir= os.getcwd(),
                                    title= "Please select a file:",
                                    filetypes= self.pickedfiletypes)
        ...

root = tk.Tk()
app = Application(master=root)
app.mainloop()
TypeError: askopenfilename() takes 0 positional arguments but 1 was given

All the tutorials and examples I see give it positional arguments. This is an example I found on pythonspot.com, which looks pretty much the same from what I can tell aside from not using a variable.

root.filename =  filedialog.askopenfilename(initialdir = "/",title = "Select file",filetypes = (("jpeg files","*.jpg"),("all files","*.*")))

remove self in

self.fileselect = tk.filedialog.askopenfilename(self,
                                    initialdir= os.getcwd(),
                                    title= "Please select a file:",
                                    filetypes= self.pickedfiletypes)

it works!

  • Ok, so that worked, but why? Isn't the first argument for the parent window? Also, that means it opens a window to select something, but I wouldn't be able to change the selection, or choose when to open it. Since it should have multiple images to be selected, that'll be really frustrating.
