Changing the Color of a Single Word in a Tkinter Canvas

If you're developing a Python application using Tkinter, you might encounter a scenario where you want to change the color of just one word within a block of text that you display on a canvas. This can often be tricky, especially if you're using the create_text() method, which does not support direct color changes for specific words. In this guide, we’ll explore how to achieve this effect in a clear and organized manner.

The Problem

You have a canvas with multi-line text, and you wish to change the color of one specific word without altering the color of the rest of the text. Using the insert() method typically flounders when you attempt to modify the color of individual words in the existing text. Don’t worry! We will show you how to get around this limitation.

Understanding the Solution

To tackle this problem, we will utilize the following steps:

Set Up the Canvas: Create a Tkinter canvas.

Create the Original Text: Set up the text you want to display.

Change Color: Create a method to change the color of a specific word by rendering the text multiple times, where each version has different segments highlighted.

Getting Started with Tkinter

First, let's create a simple Python script to set up a Tkinter canvas:

Defining Your Text

Now, let’s define the text you want to display, including the word that needs a different color:

Creating the Function to Change Color

We'll develop a function called change_color that will accept the sentence, the desired color, and the start and end positions of the word you want to change:

Parameters:

sentence: The full text including the word whose color we want to change.

color: The color that we want to apply to that specific word.

start_p and end_p: The start and end indices of the word you want to change, respectively.

Calling the Function

To change the word "red" to a different color, we simply need to call the function with the parameters that correspond to its position:

In this code, start_p is set to 70 and end_p to 73, which correspond to the positions of the word "red" in the string.

Conclusion

And there you have it! By using multiple create_text calls, you can easily change the color of individual words in a block of text on a Tkinter canvas. This method retains the integrity of your entire text block while allowing customization of specific elements within it.

Feel free to modify the example to suit your needs, and happy coding with Tkinter!
