Question

我想用Tkinter在python中创建一个简单的GUI。

我从stackoverflow搜索了很多链接，基于这些链接，我可以提供以下代码。但是，按钮不在最下面一行。我认为问题是因为帧大小不等于父窗口大小。框架大小仅取决于区域小部件的覆盖范围。

import Tkinter as tk

master=tk.Tk()
master.title("Title")
master.geometry("500x400")

class makeframe(object):

    def __init__(self,i):
        self.i=i

        self.frame=tk.Frame(master, bg = 'blue', width = 400, height = 400)
        if(self.i == 0):
            self.first_frame()
        elif(self.i == 1):
            self.second_frame()
        else:
            self.third_frame()

    def next(self):
        self.frame.grid_forget()
        p[self.i+1].frame.grid()

    def back(self):
        self.frame.grid_forget()
        p[self.i-1].frame.grid()

    def first_frame(self):

        self.nextbutton = self.next_button("Add New")
        self.nextbutton.place(relx=0.90, rely=0.99, anchor=tk.SE)

        self.backbutton = self.prev_button("Run Predefined")
        self.backbutton.grid(column=0,row=0, padx = 2, pady = 2)

        var = tk.StringVar()
        self.label = tk.Label(master, textvariable=var,
                     relief=tk.RAISED, bg='gray', fg='black')
        var.set("Welcome to Title \n(A software for testing)")

    def second_frame(self):

        tk.Label(self.frame, text="INSAMPLE: ").grid(row=0)
        tk.Label(self.frame, text="OUTSAMPLE: ").grid(row=1)
        tk.Label(self.frame, text="RESULT DIRECTORY: ").grid(row=2)
        tk.Label(self.frame, text="INPUT DIRECTORY: ").grid(row=3)
        tk.Label(self.frame, text="INPUT FILENAME: ").grid(row=4)
        tk.Label(self.frame, text="INDEX COLUMNNAME: ").grid(row=5)
        tk.Label(self.frame, text="INPUT FILEEXTENSION: ").grid(row=6)
        tk.Label(self.frame, text="COLUMNNAME: ").grid(row=7)

        tk.Entry(self.frame).grid(row = 0, column = 1)
        tk.Entry(self.frame).grid(row = 1, column = 1)
        tk.Entry(self.frame).grid(row = 2, column = 1)
        tk.Entry(self.frame).grid(row = 3, column = 1)
        tk.Entry(self.frame).grid(row = 4, column = 1)
        tk.Entry(self.frame).grid(row = 5, column = 1)
        tk.Entry(self.frame).grid(row = 6, column = 1)
        tk.Entry(self.frame).grid(row = 7, column = 1)

        self.nextbutton = self.next_button("Next")
        self.nextbutton.place(relx=0.90, rely=1.1, anchor=tk.SE)

        self.backbutton = self.prev_button("Previous")
        self.backbutton.place(relx=0.10, rely=1.1, anchor=tk.SW)

    def third_frame(self):

        tk.Label(self.frame, text="Method name: ").grid(row=0)
        tk.Label(self.frame, text="Method name: ").grid(row=1)
        tk.Label(self.frame, text="Method name: ").grid(row=2)
        tk.Label(self.frame, text="Method name: ").grid(row=3)
        tk.Label(self.frame, text="Method name: ").grid(row=4)

        tk.Entry(self.frame).grid(row=0, column=1)
        tk.Entry(self.frame).grid(row=1, column=1)
        tk.Entry(self.frame).grid(row=2, column=1)
        tk.Entry(self.frame).grid(row=3, column=1)
        tk.Entry(self.frame).grid(row=4, column=1)

        self.nextbutton = self.next_button("Create Strategies")
        self.nextbutton.place(relx=0.90, rely=0.99, anchor=tk.SE)

        self.backbutton = self.prev_button("Previous")
        self.backbutton.place(relx=0.10, rely=0.99, anchor=tk.SW)

    def next_button(self, string):
        return tk.Button(self.frame, text=string,
            bg='gray', fg='black', command = self.next)

    def prev_button(self, string):
        return tk.Button(self.frame, text=string,
                        bg='gray', fg='black', command = self.back)


n=3
p=[0]*n
for i in range(n):
    p[i]=makeframe(i)
p[0].frame.grid()
p[-1].nextbutton.config(state=tk.DISABLED)
master.mainloop()

按钮似乎可以正常工作，但这是小部件的放置，这对我来说是真正的问题。我希望它们覆盖良好的空间，并在右下方和左下方居中，并放置按钮。我是第一次尝试gui。抱歉，问题很简单。

通过Tkinter创建下一个和上一个按钮滑动布局
