Setting Up Tkinter

Tkinter is included with the standard Python distribution. To verify Tkinter is installed, you can try importing it in a Python shell:

import tkinter as tk

If this command runs without error, Tkinter is installed and ready to use.

Your First Tkinter Program

Let's create a simple window using Tkinter.

                        import tkinter as tk

                        # Create the main window (root window)
                        root = tk.Tk()

                        # Set the window title
                        root.title("Hello Tkinter")

                        # Set the window size
                        root.geometry("400x300")

                        # Run the application
                        root.mainloop()

                    

Explanation:

• tk.Tk(): Initializes the main window.
• root.title("Hello Tkinter"): Sets the title of the window.
• root.geometry("400x300"): Sets the size of the window (width x height).
• root.mainloop(): Starts the event loop, waiting for user interactions.

Basic Widgets

• Label: Displays text or images.
• Button: A clickable button.
• Entry: A single-line text box.
• Text: A multi-line text box.
• Frame: A container for organizing other widgets.

Example with a Label and a Button:

                        import tkinter as tk

                        def on_button_click():
                            label.config(text="Button Clicked!")

                        # Create the main window
                        root = tk.Tk()
                        root.title("Simple Tkinter App")
                        root.geometry("300x200")

                        # Create a Label
                        label = tk.Label(root, text="Hello, Tkinter!")
                        label.pack(pady=10)

                        # Create a Button
                        button = tk.Button(root, text="Click Me", command=on_button_click)
                        button.pack(pady=10)

                        # Run the application
                        root.mainloop()

                    

Explanation:

• tk.Label: Creates a label widget.
• label.pack(): Packs the label into the window, managing its placement.
• tk.Button: Creates a button widget.
• button.pack(): Packs the button into the window.
• command=on_button_click: Binds the button click event to the on_button_click function.
