Python tkinter框架不显示小部件

我正在尝试用tkinter创建gui。我正在使用python3.6 我使用tkinter制作框架，现在当我尝试添加按钮、标签等时，它不会在输出屏幕中显示按钮或标签

---

以及如何使用pack为框架使用pack，以及如何使用网格为框架中的小部件使用pack。

您还没有调用定义了属性的函数。最后，只需在代码中添加_price_输入即可调用函数：

from tkinter import *
import tkinter.messagebox


def message():
    text='''sfjkasjdfkjasdfjsdjfjsdlfjasd
            fjsdkfjksadjfsajdjfl    
            sdfasdjflsjdlfsldjflsjd'''
    tkinter.messagebox.showinfo("showing",text)


def _price_inputs():
    win2 = Tk()
    win2.title("Transactions for the project Botique")
    win2.geometry("1600x800+0+0")
    win2.configure(bg="black")


    framex = Frame(win2,width=1600,bg="RoyalBlue4",height=100,relief=GROOVE).pack(side=TOP)
    frame1 = Frame(win2,width=1000, height=400,bg="white", relief=SUNKEN).pack(side=RIGHT,fill=Y)
    frame2 = Frame(win2, width=775,height=100,bg="white", relief=FLAT).pack(side=BOTTOM)
    frame3 = Frame(win2,width=600,height=430,bg="gray",relief=FLAT).pack(side=LEFT,fill=X)

    #framex == heading
    #frame1 == showing the infos 
    #frame2 == bottom_infos
    #frme3 == adding the buttons and widgets

    #==++++===========================title=============================

    lbl1 = Label(framex,font=("arial", 30, "bold"),bg="powder blue",fg="green",text="Hello this is the title of the page",bd=10,relief=GROOVE).pack(side=TOP)

    btn1 = Button(frame1,font=("arial",20,"bold"),bg="powder blue",fg="white",text="click me").pack()


    win2.mainloop() 

您无法看到新项目lbl1和btn1，因为它们是：

win2的子对象，而不是任何帧 被另一帧阻止，帧3 1. lbl1和btn1是win2的子对象，因为将None作为第一个位置参数传递，或者默认情况下，小部件的父对象被指定为Tk实例

lbl1和btn1被实例化为无父参数，因为：

from tkinter import *
import tkinter.messagebox


def message():
    text='''sfjkasjdfkjasdfjsdjfjsdlfjasd
            fjsdkfjksadjfsajdjfl    
            sdfasdjflsjdlfsldjflsjd'''
    tkinter.messagebox.showinfo("showing",text)


def _price_inputs():
    win2 = Tk()
    win2.title("Transactions for the project Botique")
    win2.geometry("1600x800+0+0")
    win2.configure(bg="black")


    framex = Frame(win2,width=1600,bg="RoyalBlue4",height=100,relief=GROOVE).pack(side=TOP)
    frame1 = Frame(win2,width=1000, height=400,bg="white", relief=SUNKEN).pack(side=RIGHT,fill=Y)
    frame2 = Frame(win2, width=775,height=100,bg="white", relief=FLAT).pack(side=BOTTOM)
    frame3 = Frame(win2,width=600,height=430,bg="gray",relief=FLAT).pack(side=LEFT,fill=X)

    #framex == heading
    #frame1 == showing the infos 
    #frame2 == bottom_infos
    #frme3 == adding the buttons and widgets

    #==++++===========================title=============================

    lbl1 = Label(framex,font=("arial", 30, "bold"),bg="powder blue",fg="green",text="Hello this is the title of the page",bd=10,relief=GROOVE).pack(side=TOP)

    btn1 = Button(frame1,font=("arial",20,"bold"),bg="powder blue",fg="white",text="click me").pack()


    win2.mainloop()
_price_inputs()

行与以下行相同：

framex = Frame(win2,width=1600,bg="RoyalBlue4",height=100,relief=GROOVE).pack(side=TOP)
...
frame1 = Frame(win2,width=600,height=430,bg="red",relief=FLAT).pack(side=LEFT,fill=X)

因为framex和frame3都是

可以通过将geometry manager行与小部件实例化行分离来解决此问题：

Frame(win2,width=1600,bg="RoyalBlue4",height=100,relief=GROOVE).pack(side=TOP)
framex = None
...
Frame(win2,width=600,height=430,bg="red",relief=FLAT).pack(side=LEFT,fill=X)
frame1 = None

2. 注释掉frame3行，以查看lbl1和btn1实际存在：

framex = Frame(win2,width=1600,bg="RoyalBlue4",height=100,relief=GROOVE)
framex.pack(side=TOP)
...
frame1 = Frame(win2,width=600,height=430,bg="red",relief=FLAT)
frame1.pack(side=LEFT,fill=X)

你不叫_price_inputs方法吗？你可以随时发布你的问题帖子，以便更好地改进你的问题。我试过了，但没有起作用。除了在评论中说第二行，你能帮我解决问题吗？这可能重复修复了问题代码，没有解释对其他人没有多大帮助。你能描述一下你是如何解决这个问题的吗？

#frame3 = Frame(win2,width=600,height=430,bg="red",relief=FLAT).pack(side=LEFT,fill=X)
