Complete Course on Python Tkinter GUI Design Using ttkbootstrap

In this tutorial, we will explore how to design GUI applications in Python using the Tkinter module and ttkbootstrap. Tkinter is the standard GUI toolkit for Python, and ttkbootstrap is a package that allows you to create beautiful and modern looking GUIs with ease. By the end of this course, you will have the skills to create professional-looking applications using Python and ttkbootstrap.

Let’s get started!

1. Installation:
   Before we can start designing GUI applications using Tkinter and ttkbootstrap, we need to install the required packages. To install Tkinter, simply run the following command:

   pip install tk

To install ttkbootstrap, run the following command:

pip install ttkbootstrap

1. Importing necessary modules:
   To start creating GUI applications, we need to import the necessary modules. Here is an example of how you can import Tkinter and ttkbootstrap in your Python script:

   import tkinter as tk
   from ttkbootstrap import Style

2. Creating a basic Tkinter window:
   Now that we have imported the necessary modules, let’s create a basic Tkinter window using ttkbootstrap styles. Here is an example code snippet to create a simple window with a title using ttkbootstrap:

   root = tk.Tk()
   style = Style()
   root.title("My First GUI Application")

3. Applying themes and styles:
   One of the key features of ttkbootstrap is the ability to apply themes and styles to your GUI applications. You can apply different themes like ‘light’, ‘dark’, ‘sandstone’, and ‘superhero’ to your applications. Here is an example of how you can apply a ‘superhero’ theme to your GUI application:

   style.theme_use('superhero')

You can also apply custom styles to different widgets in your GUI application. Here is an example of how you can apply a custom style to a button widget:

style.configure('my.TButton', font=('Helvetica', 12, 'bold'))
button = tk.Button(root, text="Click me", style='my.TButton')

1. Creating widgets:
   Now that we have applied themes and styles to our GUI application, let’s start creating widgets like buttons, labels, entry fields, etc. Here is an example of how you can create a button and a label widget in your GUI application:

   button = tk.Button(root, text="Click me")
   label = tk.Label(root, text="Hello World!")

2. Adding widgets to the window:
   After creating widgets, we need to add them to the window. Here is an example of how you can add a button and a label widget to your GUI application:

   button.pack()
   label.pack()

3. Responding to events:
   One of the key aspects of GUI applications is handling user events. You can respond to events like button clicks, keypresses, etc. Here is an example of how you can respond to a button click event in your GUI application:

   
   def on_button_click():
   print("Button clicked!")

button = tk.Button(root, text="Click me", command=on_button_click)

8. Building a complete GUI application:
Now that you have learned the basics of designing GUI applications using Tkinter and ttkbootstrap, you can create a complete GUI application by combining the concepts we have covered in this course. Here is an example of a simple calculator application built using Tkinter and ttkbootstrap:
```python
def add():
    result.set(int(num1.get()) + int(num2.get()))

root = tk.Tk()
style = Style()
root.title("Simple Calculator")

num1 = tk.StringVar()
num2 = tk.StringVar()
result = tk.StringVar()

tk.Entry(root, textvariable=num1).pack()
tk.Entry(root, textvariable=num2).pack()
tk.Button(root, text="Add", command=add).pack()
tk.Label(root, textvariable=result).pack()

style.theme_use('superhero')

root.mainloop()

Congratulations! You have now completed the Python Tkinter GUI Design Using ttkbootstrap course. You now have the skills to create professional-looking GUI applications using Python and ttkbootstrap. Keep practicing and exploring more features of Tkinter and ttkbootstrap to create even more advanced GUI applications. Happy coding!
