How to Set Text of Tkinter Text Widget With a Button?

To set the text of a Tkinter Text widget using a button, you can define a function that updates the content of the Text widget and then associate this function with a button's command attribute.

Here's a step-by-step example:

  • Import necessary modules:
import tkinter as tk
  • Define the function to update the Text widget:
def set_text(): # Clear the content of the Text widget text_widget.delete("1.0", tk.END) # Insert new content into the Text widget text_widget.insert(tk.END, "New text content!")
  • Create the main window, Text widget, and button:
root = tk.Tk() root.title("Update Text Widget") # Create the Text widget text_widget = tk.Text(root, height=5, width=30) text_widget.pack(pady=20) # Create the Button to update the Text widget's content update_button = tk.Button(root, text="Update Text", command=set_text) update_button.pack(pady=20) root.mainloop()

When you run the above code, you'll get a window with a Text widget and a button. Clicking the button will replace the content of the Text widget with the text "New text content!".

You can modify the set_text function to set any content you want in the Text widget when the button is pressed.
