Python Tkinter mini-project - Window Resizer

Let's create a python and Tkinter project to brush up on your technical skills. Creating projects is the best way of learning something faster.

First of all let's create a GUI window

from tkinter import * 

root = Tk()
root.title("Tkinter Resizer - Yourname")
root.geometry('250x200')
root.configure(background="#c9db02")


root.mainloop()

Great. Now move to the next step i.e creating a Label to display text in our root window.

Creating Label text to display in the root window

# Displaying label text in the root window
Label(root, text="Width: ", font="courier 20 bold", bg='#c9db02').grid(row=0, column=0, pady=30)
Label(root, text="Height: ", font="courier 20 bold", bg='#c9db02').grid(row=1, column=0, pady=30)

Create slider to set height and width

# Scale silder provides graphical slider where we set the value of width and height
width = Scale(root, from_=100, to=800, command=resize_window, orient=HORIZONTAL, width=20, bg='#c9db02')
height = Scale(root, from_=100, to=800, command=resize_window, orient=HORIZONTAL, width=20, bg='#c9db02')
width.grid(row=0, column=1)
height.grid(row=1, column=1)

So far so good. Now let's create a new window that we controlled using a slider. Write the below code after the fifth line or after root.configure()

Toplevel window or new window

#Creating new window
top = Toplevel()
top.configure(background="#0a3b2a")
top.title("Resizing....")

It's time to create a function that is able to take the value of the height and width of the new window Write down below code after Toplevel()

A function that takes the value of width and height

# Function where we put width and height
def resize_window(*args): 
    top.geometry(f"{width.get()}x{height.get()}")

Congratulation. You made it

How the whole code looks like

from tkinter import * 

root = Tk()
root.title("Tkinter Resizer - Sailendra")
root.geometry('250x200')
root.configure(background="#c9db02")

# Creating new window
top = Toplevel()
top.configure(background="#0a3b2a")
top.title("Resizing....")

# Function where we put width and height
def resize_window(*args): 
    top.geometry(f"{width.get()}x{height.get()}") 

# Displaying label text in the root window
Label(root, text="Width: ", font="courier 20 bold", bg='#c9db02').grid(row=0, column=0, pady=30)
Label(root, text="Height: ", font="courier 20 bold", bg='#c9db02').grid(row=1, column=0, pady=30)

# Scale silder provides graphical slider where we set the value of width and height
width = Scale(root, from_=100, to=800, command=resize_window, orient=HORIZONTAL, width=20, bg='#c9db02')
height = Scale(root, from_=100, to=800, command=resize_window, orient=HORIZONTAL, width=20, bg='#c9db02')
width.grid(row=0, column=1)
height.grid(row=1, column=1)

root.mainloop()
