Question

我是python的新手，所以我试图制作一个GUI，因为我必须在特定位置放置一个按钮。

我尝试使用self.nxt_form.place(x=200,y=100)代替self.nxt_form.pack()。

但按钮消失了，只有框架出现时才出现。你能告诉我如何把按钮放在特定的位置吗？

以下是代码：

import tkinter as tk

class Main_form:
def __init__(self, root,title="Simulated MTBF"):
self.root = root
    self.frame = tk.Frame(self.root)
    """Button nxt_form which moves to next form"""
    self.nxt_form = tk.Button(self.frame, text = 'Next Form', width = 25,command = self.new_window)
    self.nxt_form.pack()
    self.frame.pack()
     """command to open new window by clicking Button """
def new_window(self):
    self.newWindow = tk.Toplevel(self.root)
    self.app = Demo2(self.newWindow)

 class Demo2:
        def __init__(self, root):
    self.root = root
    self.frame = tk.Frame(self.root)
    self.quitButton = tk.Button(self.frame, text = 'Quit', width = 25, command = self.close_windows)
    self.quitButton.pack()
    self.frame.pack()
def close_windows(self):
    self.root.destroy()

def main(): 
root = tk.Tk()
app = Main_form(root)
root.mainloop()

if __name__ == '__main__':
main()

当我使用tkinter时，我使用了列和行来定位对象

self.btn = tk.Button(self, text = "button")
self.btn.grid(row = 1, column = 1)

EDIT - 针对评论（见下文）扩展了信息

我会做一个标签并改变它的宽度和高度来制作你需要的间距（注意我也是python的初学者，所以这可能是一个糟糕的方式，但它有效）

from tkinter import *
import tkinter as tk
from tkinter.ttk import Combobox,Treeview,Scrollbar

class MainMenu(Frame):
    def __init__(self, master):
        """ Initialize the frame. """
        super(MainMenu, self).__init__(master)
        self.grid()
        self.create_GUI()

    def create_GUI(self):
        frame1 = tk.LabelFrame(self, text="frame1", width=300, height=130, bd=5)
        frame1.grid(row=0, column=0, columnspan=3, padx=8)
        #the frame is not needed but it is a good thing to use as can group
        #parts of your interface together

        self.text1 = Entry(frame1)
        #note if you were not using frames would just put self here
        self.text1.grid(row = 1, column = 0)

        self.text2 = Label(frame1, text = "",height = 10)
        self.text2.grid(row = 2 , column = 0)

        self.text3 = Entry(frame1)
        self.text3.grid(row = 3, column = 0)



root = Tk()
root.title("hi")
root.geometry("500x500")
root.configure(bg="white")
app = MainMenu(root)
root.mainloop()

另请注意，您不能将pack和grid一起使用，您可以做的是将对象分组到不同的帧中，然后在一个帧中使用网格并打包在不同的帧中。我个人更喜欢使用网格打包，因为它可以让你更好地控制你的对象然后打包

如何让Tkinter按钮放置在特定位置？
