TkInter：我如何让对象出现在我的第二个窗口而不是第一个？

    name_entry_label.place(x=7,y=-25,width=80,height=83)

#SEARCH FOR OVERDUE MEMBERSHIP PAYMENTS 

search_overdue_membership_payments_button=Button(text="Search for overdue membership payments")#,command=overdue_membership_payments) 
search_overdue_membership_payments_button.place(x=10,y=130,width=235,height=20) 

menu_window.mainloop()

Here is a screenshot of my two windows. The smaller cluttered window is a window where the user clicks on the first button in order to get the second window to appear. The larger window should have various objects on it, but instead these are all placed added to the smaller window.TkInter：我如何让对象出现在我的第二个窗口而不是第一个？

**从不**在同一应用程序中创建两个根窗口'xx = Tk（）'。将Toplevel（）用于除根窗口以外的窗口。但这不是你所看到的原因。这是一个养育子女的问题。 –

from tkinter import * 

def new_member(): 

#This is for the larger window 
new_member_window = Toplevel() 
new_member_window.title("Add a new member") 
new_member_window.geometry("500x500") 

#NAME ENTRY 

name_entry_label = Label(new_member_window, text = "Enter a new member's name:") 
name_entry_label.place(x=7,y=-25,width=80,height=83) 

name_box = Entry(new_member_window, text="") 
name_box.place(x=100,y=10,width=100,height=15) 

#AGE ENTRY 

age_entry_label = Label(new_member_window, text = "Enter their age:") 
age_entry_label.place(x=7,y=10,width=80,height=83) 

age_box = Entry(new_member_window,text="") 
age_box.place(x=100,y=45,width=100,height=15) 

#EMAIL ADRESS ENTRY 

email_entry_label = Label(new_member_window, text = "Enter their email:") 
email_entry_label.place(x=10,y=45,width=80,height=83) 

age_box = Entry(new_member_window, text="") 
age_box.place(x=100,y=80,width=100,height=15) 



#All below is for the smaller window 
menu_window = Tk() 
menu_window.title("Sports Club Membership") 
menu_window.geometry("264x164") 

menu_label=Label(text="Main menu",font=("Helvetica",20,"underline","bold")) 

menu_label.place(x=10,y=10) 

#ADD A NEW MEMBER BUTTON 

menu_new_member_button=Button(text="Add a new member",command=new_member) 
menu_new_member_button.place(x=10,y=70,width=120,height=20) 

#SEARCH MEMBER JOINING DATES 
    search_member_join_dates_button=Button(text="Search member joining 
dates")#,command=member_joining_dates) 
search_member_join_dates_button.place(x=10,y=100,width=170,height=20) 

    #SEARCH FOR OVERDUE MEMBERSHIP PAYMENTS 

search_overdue_membership_payments_button=Button(text="Search for overdue 
membership payments")#,command=overdue_membership_payments) 

search_overdue_membership_payments_button.place(x=10,y=130,width=235,height=20) 




menu_window.mainloop()

不要叫根两次，但使用的Toplevel为您的功能，同时指定窗口你想要放置你的小部件。

这个答案的缩进被打破了。 –

字面回答你的问题是“告诉小部件去其中的窗口”。

你的代码有两个问题。首先是您要创建Tk的两个实例。你应该总是明确地创建一个。如果您需要多个窗口，则第二个和后续窗口需要为Toplevel的实例。您还需要拨打mainloop一次。

第二个问题是您没有指定每个小部件的父级或主级。如果你不这样做，tkinter会默认到根窗口。如果你想menu_label成为第二个“小窗口”的一部分，你只需要简单地指出明确：

menu_window = Toplevel() 
menu_label=Label(menu_window, ...)
