Python Tkinter add function

Let us see, how to use the add function in Python Tkinter. We will see, how we can use the add function with images, two numbers, textbox, etc.

Python Tkinter add Image

In this section, we will learn how to add images in Python Tkinter.

We want to add an image on the window screen. We create a window where we want to add an image. We add the image from the dialog box. Select the image and open it. The selected image will add to the window.

Code:

in the following code, we create a window ws=Tk() Inside the window we add a button that functions like an event which helps to select an image that we want to add inside a box.

• Image. open() is used to open an image on the window.
• filedialog.askopenfilename() is used here to ask to open which file name from our local system location we want to open.
• Image.resize() helps to size the image to the defined px.

from tkinter import *
from PIL import ImageTk, Image
from tkinter import filedialog
import os

ws = Tk()
ws.title("Python Guides")
ws.geometry("550x300+300+150")
ws.resizable(width=True, height=True)

def openfun():
    filename = filedialog.askopenfilename(title='open')
    return filename
def open_img():
    a = openfun()
    imag = Image.open(a)
    imag = imag.resize((250, 250), Image.ANTIALIAS)
    imag = ImageTk.PhotoImage(imag)
    label = Label(ws, image=imag)
    label.image = imag
    label.pack()

button = Button(ws, text='Add Image', command=open_img).pack()

ws.mainloop()

Output:

In the following output, we can see a button with the label Add Image which functions to select the path of the image and input inside a box.

As earlier discussed while clicking on add image button how its function works. It is asking us from the path which image we want to add or open inside a window.

After selecting an image in this way it shows on over the window and our image is added inside a window.

Python Tkinter Add Two Numbers

In this section, we learn how to add two numbers in Python Tkinter.

The addition is taking two or more numbers and adding the numbers together. After adding the numbers we get the result.

Code:

In the following code, we create a window inside the window we add labels, entries, and buttons. The user gives the input in the entry box and the result is shown as the addition of the numbers given by the user.

Label() function is used to implement display boxes where we can place text or images.

entry() widget is used to accept single text.

from tkinter import *
 
def addnumber():
    res1=int(entry1.get())+int(entry2.get())
    mytext.set(res1)
 
ws = Tk()
ws.title("Python Guides")
ws.geometry("500x300")
mytext=StringVar()
Label(ws, text="First").grid(row=0, sticky=W)
Label(ws, text="Second").grid(row=1, sticky=W)
Label(ws, text="Result:").grid(row=3, sticky=W)
result=Label(ws, text="", textvariable=mytext).grid(row=3,column=1, sticky=W)
 
entry1 = Entry(ws)
entry2 = Entry(ws)
 
entry1.grid(row=0, column=1)
entry2.grid(row=1, column=1)
 
button = Button(ws, text="Calculate", command=addnumber)
button.grid(row=0, column=2,columnspan=2, rowspan=2,sticky=W+E+N+S, padx=5, pady=5)
 
 
ws.mainloop()

Output:

After running the above code we get the following output we see a window inside the window there is an input box that gets the values from the user after getting the value then calculates and gives the result back to the user.

Python Tkinter add Text Box

In this section, we will learn how to add a text box in Python Tkinter.

The text box allows the user to input text information to be used by the program. The user can insert multiple texts in the text box at a single time.

Code:

In the following code we create a widget inside the widget we add a text box in which the user can insert the text or by default text is a popup in the text field.

• inputtext.get() is used for getting the input from the user.
• Text() function is used for entering the text.
• Label() is used the user have to specify what to display a text or an image.
• Button()is used to submitting the text.

from tkinter import *

ws = Tk()
ws.geometry("500x300")
ws.title("Python Guides")

def take_input():
	INPUT = inputtext.get("1.0", "end-1c")
	print(INPUT)
	if(INPUT == "120"):
		Output.insert(END, 'Correct')
	else:
		Output.insert(END, "Wrong answer")
	
label = Label(text = "What is 24 * 5 ? ")
inputtext = Text(ws, height = 10,
				width = 25,
				bg = "light yellow")

Output = Text(ws, height = 5,
			width = 25,
			bg = "light cyan")

display = Button(ws, height = 2,
				width = 20,
				text ="Show",
				command = lambda:take_input())

label.pack()
inputtext.pack()
display.pack()
Output.pack()

ws.mainloop()

Output:

After running the above code we get the following output in which the user can insert the number in the text field.

After entering the text click on the show button if the answer that the user inserts in the text field is correct then the next text field show correct otherwise it shows incorrectly.

The user can insert the correct value and the value is shown on the command prompt.

The menu bar is located at the of the screen below the title bar containing a drop-down menu. The menu bar gives access to functions such as an Opening file, Edit.

Code:

In the following code, we import Toplevel, Button, Tk, Menu libraries and also create a window on the top of the window a menubar is placed containing the dropdown menu.

• file1.add_command() is used to add menu items to the menu.
• file1.add_separator() is used to separate the menu accordingly.
• menubar.add_cascade() is used to creating menu bar in proper way.

from tkinter import Toplevel, Button, Tk, Menu  
  
ws = Tk() 
ws.title("Python Guides")
ws.geometry("500x300") 
menubar = Menu(ws)  
file1 = Menu(menubar, tearoff=0)  
file1.add_command(label="New")  
file1.add_command(label="Open")  
file1.add_command(label="Save")  
file1.add_command(label="Save as...")  
file1.add_command(label="Close")  
  
file1.add_separator()  
  
file1.add_command(label="Exit", command=ws.quit)  
  
menubar.add_cascade(label="File", menu=file1)  
edit1 = Menu(menubar, tearoff=0)  
edit1.add_command(label="Undo")  
  
edit1.add_separator()  
  
edit1.add_command(label="Cut")  
edit1.add_command(label="Copy")  
edit1.add_command(label="Paste")  
edit1.add_command(label="Delete")  
edit1.add_command(label="Select All")  
  
menubar.add_cascade(label="Edit", menu=edit1)  
help1 = Menu(menubar, tearoff=0)  
help1.add_command(label="About")  
menubar.add_cascade(label="Help", menu=help1)  
  
ws.config(menu=menubar)  
ws.mainloop()

Python Tkinter add Text to Entry

In this section, we will learn how to add text to entry in Python Tkinter.

Entry is where we can input the text or we can say that text entry refers to creating a message in form of characters, numbers, etc, or sometimes by default message can also generate.

Code:

In the following code, we create a window ws=Tk() inside the window there is a text box. In which users can enter their text if the user will not provide any input then the default value will be used.

textBox.insert() is used to insert the word or sentence.

from tkinter import *
import tkinter as tk


ws = Tk()
ws.title("Python Guides")
ws.geometry("500x300")

textBox = Entry(ws)
textBox.insert(0, "Python Guides..!!")

A scrollbar is a widget in which text, Picture content can be scrolled in a predetermined direction(Horizontal or Vertical). When the content exceeds then the scrollbar is added.

Code:

In the following code, we create a window ws=Tk() we want to add a scrollbar we use Scrollbar() function to add scrollbar on the main window. Orient determines whether Scrollbar will be Vertical or Horizontal.

Scrollbar() is used for adding the Scrollbar to the main window.

from tkinter import *
class ScrollBar:
	
	def __init__(self):
				
		ws = Tk()
		ws.title("Python Guides")
		ws.geometry("200x200")		
		h1 = Scrollbar(ws, orient = 'horizontal')		
		h1.pack(side = BOTTOM, fill = X)
		v1 = Scrollbar(ws)		
		v1.pack(side = RIGHT, fill = Y)
		
		t1 = Text(ws, width = 15, height = 15, wrap = NONE,
				xscrollcommand = h1.set,
				yscrollcommand = v1.set)
	
		for i in range(20):
	        t1.insert(END,"Python Guides Tutorial..!!\n")		
		t1.pack(side=TOP, fill=X)		
		h1.config(command=t1.xview)
