生成空TKinter GUI

Question

以下TKinter代碼正在生成空TK窗口。我無法弄清楚爲什麼。我正在妥善包裝一切。地圖是應該出現的第一幀，但是當它啓動時，只有沒有任何圖像或按鈕的頂部欄。我也嘗試首先發射hydra水平框架，它會產生相同的結果。

class GUI_Control(Tk): 
    def __init__(self, player, control, *args, **kwargs): 
     self.player = player 
     self.delegate = control 
     Tk.__init__(self, *args, **kwargs) 
     self.window = Frame(self) 
     self.window.pack() 

     #specify frames that can be loaded into the TK window. These will be defined in subclasses of Tk.Frame 
     self.frames = {} 

     #setup initial frame, all frames take GUI_Control as a listener to control event handling with window changes 
     level_keys = [Map, Hydra_Level] 
     for level in level_keys: 
      frame = level(self.window, self) 
      self.frames[level] = frame 

     self.show(Map) 



    #show the frame from the dictionary in the tkinter window 
    def show(self, controller): 
     frame = self.frames[controller] 
     print(isinstance(frame, Frame)) 
     frame.tkraise() 

    def open(self): 
     self.mainloop() 

    def switch(self): 
     pass 


class Map(Frame): 
    def __init__(self, master, controller, *args, **kwargs): 
     Frame.__init__(self, master) 
     self.controller = controller 
     # define map gui here 
     self.map_picture = PhotoImage(file=r"images/archipelago.gif") 
     self.image = Label(self, image=self.map_picture) 
     self.image.pack(padx=10, pady=10) 
     self.go_to_button = Button(self, text="Go to", command=lambda: self.controller.show(Hydra_Level)) 
     self.go_to_button.pack() 


class Hydra_Level(Frame): 
    def __init__(self, master, controller, *args, **kwargs): 
     Frame.__init__(self, master) 
     self.listener = master 
     self.go_to_button = Button(self, text="Back to map", command=lambda: self.controller.show(Map)) 
     self.go_to_button.grid(row=0)

我打包一切適當

不，你不是。您不致電pack，place或grid對the地圖or Hydra`對象。
