Creating a GUI in Python

A module "tkinter" needs to be imported as follows:

import tkinter as tk


A root which is the source file is then created as follows:

root = tk.Tk()


It can be modified in the following manner:

root.geometry ( " 700x500 " )

root.configure ( bg = " light blue " )


At the end root.mainloop() needs to be written to run the root window infinitely.


Labels are created to display text on the window as follows:


label = tk.Label ( root , text = " hi " , width = 10 , height = 10 , bg = " red " , fg = " white " )

These labels need to be printed as follows

label.pack () #Prints label at the top of the page in the center

label.pack ( side = " left " ) # Prints label at left of the page in the center

label.place ( x = 100 , y = 200 ) #Prints label at the given coordinates


Buttons can be created to perform variety of tasks as follows:

def sub1():

    label = tk.Label ( root,text = " Hello " , font = ( " Times new roman " , 15 ) )

    label.place ( x = 0 , y = 0 )

button1 = tk.Button ( root,text = " Click Me " , command = sub1 )

button1.configure ( bg = " blue " )

button1.place ( x = 100 , y = 350 )


Entries can be taken from the user on the window in the following manner:

entry1 = tk.Entry ( root )

entry1.place ( x = 100 , y = 205 )

These entries can be accessed and printed on the window as well


Check buttons can be created in tkinter as follows:

CheckVar1 = IntVar()

CheckVar2 = IntVar()

C1 = Checkbutton ( root , text = "Music", variable = CheckVar1, onvalue = 1, offvalue = 0, height=5, width = 20)

C2 = Checkbutton ( root , text = "Video", variable = CheckVar2, onvalue = 1, offvalue = 0, height=5, width = 20)

C1.pack()

C2.pack()


Radio button can be created in tkinter as follows:

def sel():

    selection = "You selected the option " + str(var.get())

    label.config(text = selection)


var = IntVar()


R1 = Radiobutton ( root , text= " Option 1 " , variable = var, value = 1 , command = sel )

R1.pack()


R2 = Radiobutton ( root , text = " Option 2 " , variable = var, value = 2, command = sel )

R2.pack()


R3 = Radiobutton ( root , text = " Option 3 " , variable = var, value = 3 , command = sel )

R3.pack()


label = Label ( root )

label.pack()



Message boxes can be created using:

First we need to import messagebox from tkinter and then we can created many types of messageboxes.


from tkinter import messagebox

tk.messagebox.showinfo ( " Issue " , " This is a message box to show info " )

tk.messagebox.showwarning ( " Warning " , " Critical Error " )
