tkinter- adding a new window after clicking a button built on the gui

[ShashankDS]

Hey guys,I don't know ,much about Programming I but as of now,'m trying to design an interface wherein if I click a button it should open a new Window . Also I want to know how to add a +/- button as well in the new window. I hope you guys can give me some inputs to my doubt The current code is

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55

from tkinter import font import tkinter as tk from tkinter import * import datetime #datetime.datetime(2019,1,6,15,8,24,78915)   win =tk.Tk()   myFont = font.Font(family = 'Arial', size = 14, weight = 'bold') titlefont = font.Font(family = 'Arial', size = 18, weight = 'bold') win.title("Welcome to Manchester United") win.geometry('1000x600') win.configure(background='white') title = tk.Label(win, text="Main Menu",font = titlefont) title.grid(row=1,column=3,padx=40,pady=10) Datetitle = tk.Label(win, text="Day/Month/Year:",font = myFont) Datetitle.grid(row=1,column=4,padx=50) Timetitle = tk.Label(win, text="Time:",font = myFont) Timetitle.grid(row=2,column=4,padx=50)     ConnectLogo=PhotoImage(file="Connect.png") Connect  = Button(win,image=ConnectLogo,text = "Connect", font = myFont,height =100 , width = 100,compound=TOP,bg = "orange") Connect.grid(row=3,column=1,padx=50,pady=40)   FrequencyLogo=PhotoImage(file="Frequency.png") Frequency = Button(win,image=FrequencyLogo, text = "Frequency", font = myFont, height = 100, width =180,compound=TOP,bg = "Yellow") Frequency.grid(row=3,column=2,padx=10)   MaskLogo=PhotoImage(file="Mask.gif") Mask = Button(win,image=MaskLogo, text = "Mask", font = myFont, height = 100, width =180,compound=TOP,bg = "yellow") Mask.grid(row=3,column=3,padx=10)   ToneLogo=PhotoImage(file="Tone.gif") Tone = Button(win,image=ToneLogo, text = "Tone", font = myFont, height = 100, width =180,compound=TOP,bg = "yellow") Tone.grid(row=3,column=4,padx=10)   VolumeLogo=PhotoImage(file="Volume.gif") Volume = Button(win,image=VolumeLogo, text = "Volume", font = myFont, height = 100, width =180,compound=TOP,bg = "yellow") Volume.grid(row=4, column=2,padx=10,pady=15)   TestselectLogo=PhotoImage(file="Testselect.gif") Testselect = Button(win,image=TestselectLogo, text = "Test Select", font = myFont, height = 100, width =190,compound=TOP,bg = "yellow") Testselect.grid(row=4, column=3,padx=10,pady=15)   StirLogo=PhotoImage(file="StirLogo.png") Stir = Button(win,image=StirLogo, text = "Programmed Stir", font = myFont, height = 100, width =210,compound=TOP,bg = "pink") Stir.grid(row=4, column=4,padx=10,pady=15)   SettingsLogo=PhotoImage(file="SettingsLogo.png") Settings = Button(win,image=SettingsLogo, text = "Settings", font = myFont, height = 100, width =100,compound=TOP,bg = "orange") Settings.grid(row=5, column=1,padx=10,pady=15)     mainloop()

To add the new window I want to know whether the following code ca be used:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

from Tkinter import *   class Window(Tk):     def __init__(self, parent):         Tk.__init__(self, parent)         self.parent = parent         self.initialize()       def initialize(self):         self.geometry("600x400+30+30")         wButton = Button(self, text='text', command = self.OnButtonClick())         wButton.pack()       def OnButtonClick(self):         top = Toplevel()         top.title("title")         top.geometry("300x150+30+30")         topButton = Button(top, text="CLOSE", command = self.destroy)         topButton.pack()     if __name__ == "__main__":     window = Window(None)       window.title("title")       window.mainloop()

The second code does what you want with the following changes
fix the import by removing the capitol t and don't use * import
remove the () from command = self.OnButtonClick()

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

import tkinter as tk    class Window(tk.Tk):     def __init__(self, parent):         tk.Tk.__init__(self, parent)         self.parent = parent         self.initialize()        def initialize(self):         self.geometry("600x400+30+30")         wButton = tk.Button(self, text='text', command = self.OnButtonClick)         wButton.pack()        def OnButtonClick(self):         top = tk.Toplevel()         top.title("title")         top.geometry("300x150+30+30")         topButton = tk.Button(top, text="CLOSE", command = top.destroy)         topButton.pack()       if __name__ == "__main__":     window = Window(None)        window.title("title")        window.mainloop()
