Question

class RehabArm(tk.Tk):

    def __init__(self, *args, **kwargs):
        tk.Tk.__init__(self, *args, **kwargs)
        tk.Tk.iconbitmap(self, default="nurse.ico")
        tk.Tk.wm_title(self, "Rehabilitation Arm")


        container = tk.Frame(self)
        container.pack(side="top", fill="both", expand=True)
        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)


        menubar = tk.Menu(container)
        filemenu = tk.Menu(menubar, tearoff=0)
        filemenu.add_command(label="Save Settings",
                             command = lambda: popupmsg("Not supported just yet"))
        filemenu.add_separator()
        filemenu.add_command(label="Exit", command=quit)
        menubar.add_cascade(label="File", menu=filemenu)
        #logo=tk.Icon(filemenu, file="home.ico")


        helpmenu = tk.Menu(menubar, tearoff=0)
        helpmenu.add_command(label="Tutorial", command=tutorial)
        menubar.add_cascade(label="Help", menu=helpmenu)

        tk.Tk.config(self, menu=menubar)

        self.frames = {}

        #add each page here
        for F in (WelcomePage, StartPage, ExitPage, DetailsPage, ExercisePage,
                  ActivePage, PassivePage, CommentPage, SavePage, PageThree): 

            frame = F(container, self)
            self.frames[F] = frame
            frame.grid(row=0, column=0, sticky="nsew") #sticky north south east west

        self.show_frame(WelcomePage)

    def show_frame(self, cont):
        frame = self.frames[cont]
        frame.tkraise()


class WelcomePage(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self,parent)
        label = tk.Label(self, text="Welcome to Physiotherabot", font= SUPERLARGE_FONT)
        label.pack(pady=10, padx=10)






        button1 = ttk.Button(self, text="Start",
                            command=lambda: controller.show_frame(StartPage))
        #when using button1.grid,, it not giving any error,,,but keep loading
        button1.grid(row=1, column=1) #side=tk.TOP, fill=tk.BOTH, expand=True

        button2 = ttk.Button(self, text="Exit",
                            command=lambda: controller.show_frame(ExitPage))
        button2.pack() #side=tk.TOP, fill=tk.BOTH, expand=True

如果使用button1.pack，它可以顺利运行，我尝试配置行和列，但找不到合适的位置，因为它在运行时会继续加载。

Answer 1

您无法使用.pack()和.grid()在同一容器中对齐小部件（请参阅this answer）。

因此，在WelcomePage中，您需要选择其中一个来对齐button1和button2。

为什么“.grid”对我的编码不起作用？
