How to Strike-through Text in Label in Tkinter Python

Strike-through Text in Label in Tkinter Python

In Tkinter, the Label widget is used to display text. To apply a strike-through (strikethrough) effect on the text in a Label, we can use the font option and specify the overstrike attribute.

There are different ways to set strike-through text in Tkinter:

• Using the overstrike option in the font.
• Applying a tkFont configuration.
• Using predefined fonts with overstrike enabled.

In this tutorial, we will go through examples using the Label widget to display text with a strikethrough effect.

Examples

1. Applying Strike-through Text Using Font Overstrike

In this example, we will create a Tkinter window and use the overstrike option to strike through the text in a Label.

main.py

import tkinter as tk
from tkinter import font

# Create main window
root = tk.Tk()
root.title("tutorialkart.com - Strike-through Label Example")
root.geometry("400x200")

# Define font with strikethrough
strike_font = font.Font(family="Arial", size=14, overstrike=1)

# Create a label with strikethrough text
label = tk.Label(root, text="This text is struck through", font=strike_font)
label.pack(pady=20)

root.mainloop()

Output in Windows:

2. Using a System Font with Overstrike

In this example, we will use a system font and apply the overstrike option directly to it.

main.py

import tkinter as tk
from tkinter import font

root = tk.Tk()
root.title("tutorialkart.com - System Font Strike-through Example")
root.geometry("400x200")

# Use system font and apply overstrike
system_font = font.nametofont("TkDefaultFont")
system_font.configure(overstrike=1)

# Create a label with strikethrough text
label = tk.Label(root, text="System Font Strike-through", font=system_font)
label.pack(pady=20)

root.mainloop()

Output in Windows:

3. Strike-through Text with Custom Font and Color

In this example, we will apply a strikethrough effect to a Label with a custom font and text color.

main.py

import tkinter as tk
from tkinter import font

root = tk.Tk()
root.title("tutorialkart.com - Custom Font Strike-through")
root.geometry("400x200")

# Define a custom font with strike-through
custom_font = font.Font(family="Helvetica", size=16, overstrike=1)

# Create a label with strikethrough text and custom color
label = tk.Label(root, text="Custom Struck Text", font=custom_font, fg="red")
label.pack(pady=20)

root.mainloop()

Output in Windows:

Conclusion

In this tutorial, we explored how to apply a strike-through effect to text in a Tkinter Label widget. We used:

• The overstrike attribute in custom fonts.
• System fonts with configure(overstrike=1).
• Strikethrough text with custom colors and fonts.

By applying these techniques, you can style text in Tkinter applications for different UI requirements.
