Creating and Theming Buttons with Tkinter and ttkbootstrap in Python

Creating and Theming Buttons with Tkinter and ttkbootstrap in Python

In this tutorial, we will explore how to create a standard button in a Tkinter window using the powerful ttkbootstrap library in Python.

Buttons are a fundamental part of most graphical user interfaces (GUIs), and learning how to create and customize them is essential for building interactive tkinter applications.

We will cover the following topics:

1. Creating a button in a Tkinter window.
2. Handling button click events to trigger actions.
3. Theming buttons using ttkbootstrap to improve their appearance.

Creating a Basic Button in Tkinter (ttkbootstrap)

Before we start, you need to install the ttkbootstrap library if you haven't already. You can do this easily using pip

Here is a simple code to create a Button

# Import the ttkbootstrap library for modern styling in Tkinter
import ttkbootstrap 

# Create the main window for the application
root = ttkbootstrap.Window()

# Set the title of the window that appears in the title bar
root.title('Button Handling in ttkbootstrap') 

# Define the size of the window (300 pixels wide, 300 pixels high)
root.geometry('300x300')  # width x height

# Create a button using ttkbootstrap with the text 'Hello'
MyButton = ttkbootstrap.Button(text = 'Hello')

# Place the button inside the window using .pack(), with some vertical padding (50 pixels)
MyButton.pack(pady = 50)

# Start the Tkinter event loop to display the window and keep it open
root.mainloop()

On running this code you will get the following output.

Handling Button Click Event using Tkinter

Once you have created the Button, You need to create a handler to catch the button click event.

Here we create a function called def MyButton_handler() to handle the click event and then connect your button with the event using command option

MyButton = ttkbootstrap.Button(text = 'Hello',command = MyButton_handler)

On Running the Program,You will get the following output.

On clicking the Button a message is printed on to the shell a s shown above.
