Question

我正在开发在一个窗口中具有多个框架的项目，在p2框架中有多个按钮登录，注册，添加症状，edit_symptoms，delete_symptoms 。通过按一些按钮，应该在第p5帧上完成相应的操作（预期），但我无法重复使用第p5帧，请考虑是否按下按钮 login ，那么登录代码应显示在第5帧上p5，然后按 add_Symptoms 按钮，应删除先前的结构，并在同一帧p5中显示add_Symptoms的新代码。

from tkinter import *
root = Tk()
root.geometry("1280x730")    
#define frames
p1 = Frame(root, background="#D3D3D3", borderwidth = 6,relief=RAISED)
p1.pack(side=RIGHT,fill="y")
p2 = Frame(root, background="#D3D3D3", borderwidth = 3,relief=RAISED)
p2.pack(side=TOP,fill="x")
p3 = Frame(root, background="#D3D3D3", borderwidth = 2,relief=SUNKEN)
p3.pack(side=TOP,fill="x")
p4 = Frame(root, background="white")
p4.pack(side=BOTTOM,fill="x")
p5 = Frame(root, borderwidth = 2)
p5.pack(side=LEFT,anchor="n")

#Funtions for button commands
def login():
    p5.destroy()     #Getting error here
    label = Label(p5,text="Administrator Page",font=("Comic Sans MS",12,"italic"), fg = "red")
    label.pack(padx=80,pady=10)
def add():
    p5.destroy()   #Getting error here
    label = Label(p5,text="Add Symptomps",font=("Comic Sans MS",12,"italic"), fg = "green")
    label.pack(padx=80,pady=10)

add_symptoms = Button(p1,text="Add Symptoms",command=add, state=DISABLED)
add_symptoms.pack(pady=10,padx=5)
login_admin = Button(p5,text="LOGIN",font=("Comic Sans MS",15,"italic"),fg="blue",command=login, width=15)
login_admin.pack(side=RIGHT, padx=25)
root.mainloop()

从登录p5.destroy()中删除function。之后，您销毁了框架，然后要将label = Label(p5,text="Administrator Page",font=("Comic Sans MS",12,"italic"), fg = "red")包装在其中，这会导致错误。

我认为您应该看一下这个小部件toplevel，它是根窗口的从属窗口。

def login():
   # p5.destroy()     #Getting error here
    label = Label(p5,text="Administrator Page",font=("Comic Sans MS",12,"italic"), fg = "red")
    label.pack(padx=80,pady=10)
