Python Tkinter

Python Logo

The tkinter ("Tk interface") package is a standard Python interface for the Tk GUI toolbox[1].
As an exercise, let's create our first GUI with images, text, inputs and a submit button. The title given to our window is "First GUI".
Using Tkinter in your code, import the package and initialize the tkinter object accordingly:

import tkinter as tk
# initialize your tkinter object
window = tk.Tk()

Our window is defined as non-resizable with dimensions set to 600 x 480 as follows:

# initialize your tkinter object
window = tk.Tk()
window.resizable(False,False)
window.geometry("600x480")
window.title("First GUI.")

A frame is a widget that can be used to hold other widgets, and we've used two frames in the tk window above: one for images and text with dimensions set to 600×300, and another for input fields with dimensions set to 600×100.

# create frame
frame = tk.Frame(window, width=600, height=300, background="white")
frame.pack(side=tk.TOP)
 
# create frame bottom
frame_bottom = tk.Frame(window, width=600, height=100, background="white")
frame_bottom.pack(side= tk.TOP)

Canva [2] is used to display images and fields in our window. We used this widget as follows:

# -----------------------
# TOP FRAME ELEMENTS
# -----------------------
 
# image container
canvas = tk.Canvas(frame, width=200,height=300, bg="white",bd=1, highlightthickness=0,relief="solid")
canvas.pack(side=tk.LEFT,fill='both', expand='yes',padx=5,pady=5)
 
img = tk.PhotoImage(file="img_data/android-chrome-192x192.png")
canvas.create_image(100, 150, anchor=tk.CENTER, image=img)
 
#right canvas
canvas_right = tk.Canvas(frame, width=400,height=300, bd=1, highlightthickness=0,relief="solid")
canvas_right.pack(side=tk.RIGHT ,fill=tk.BOTH, expand='yes',padx=5,pady=5)
 
# text canvas
text = '''
Lorem ipsum dolor sit amet, 
consectetur adipiscing elit. 
Curabitur venenatis purus vel\n
lectus sollicitudin bibendum. 
'''
canvas_right.create_text(200,150,fill="black", font="Times 15 bold",
                        text=text, anchor=tk.CENTER)
 
# -----------------------
# BOTTOM FRAME ELEMENTS
# -----------------------
 
# add entries in the bottom frame
canvas_frame_bottom = tk.Canvas(frame_bottom, width=600, height=100, bd=1, highlightthickness=0,relief="solid")
canvas_frame_bottom.pack(fill='both',expand='yes',padx=5,pady=2)
 
entr_one_text = tk.StringVar()
entr_one_text.set("Enter your first name")
 
entr_two_text = tk.StringVar()
entr_two_text.set("Enter your last name")
 
entr_third_text = tk.StringVar()
entr_third_text.set("Enter your phone number.")
 
# first entry
entry_one_label = tk.Label(canvas_frame_bottom, text="First name:", width=200,anchor=tk.W)
entry_one_label.pack()
 
entry_one = tk.Entry(canvas_frame_bottom, textvariable=entr_one_text, width =400)
entry_one.pack()
 
# second entry
entry_two_label = tk.Label(canvas_frame_bottom, text="Last name", width=200,anchor=tk.W)
entry_two_label.pack()
 
entry_two = tk.Entry(canvas_frame_bottom, textvariable=entr_two_text, width = 400)
entry_two.pack()
 
# third entry
entry_three_label = tk.Label(canvas_frame_bottom, text="Phone number", width=200,anchor=tk.W)
entry_three_label.pack()
 
entry_three = tk.Entry(canvas_frame_bottom, textvariable=entr_third_text, width =400)
entry_three.pack()
 
submit = tk.Button(canvas_frame_bottom, text="Submit",fg="white",bg="purple",width=200,height=15,relief=tk.GROOVE)
submit.pack(pady=2)

Use the mainloop() function in the initialized tkinter window to keep everything on your screen until the end of the program [3].

# window
window.mainloop()
