How to Highlight a Tkinter Button in macOS?
If you’re a Mac user and you’re developing an application using Tkinter, you might have noticed that Tkinter doesn’t provide any built-in functionality to highlight a button when it’s clicked or selected. This means that when a user clicks a button, it doesn’t give any visual feedback to indicate that it’s been selected.
Fortunately, there’s a way to work around this by using the tkinter.ttk
module. In this article, we’ll show you how to highlight a Tkinter button in macOS using the tkinter.ttk
module.
Installing tkinter.ttk
Before we get started, it’s important to make sure that you have tkinter.ttk
installed. This module is included in the standard library in Python 3, so if you’re using Python 3, you should already have it. However, if you’re using an earlier version of Python, you may need to install it manually.
To install tkinter.ttk
, open up a terminal and type the following command:
pip install tkinter
This will install tkinter.ttk
on your system.
Creating a Button
To create a button in Tkinter, you can use the tkinter.Button
widget. Here’s an example:
import tkinter as tk
root = tk.Tk()
my_button = tk.Button(root, text="Click me!")
my_button.pack()
root.mainloop()
This will create a simple button that says “Click me!”.
Highlighting a Button
Now let’s add some code to highlight the button when it’s clicked. First, we need to import the ttk
module from Tkinter:
import tkinter as tk
from tkinter import ttk
Next, we need to create a ttk.Style
object and set its properties to make the button look the way we want it to:
import tkinter as tk
from tkinter import ttk
root = tk.Tk()
style = ttk.Style()
style.configure('TButton', relief='raised', background="#ccc")
highlight_color = "#d9e5ff"
style.map('TButton', background=[('active', highlight_color)])
my_button = ttk.Button(root, text="Click me!")
my_button.pack()
root.mainloop()
In this example, we’re creating a ttk.Style
object and using the configure
method to set the background color of the button to #ccc
and its relief to raised
. We’re also defining a highlight_color
variable and using the map
method to change the background color of the button to the highlight_color
when it’s clicked (using the active
keyword).
Conclusion
In this article, we’ve shown you how to highlight a Tkinter button in macOS using the tkinter.ttk
module. By using this module and its Style
object, you can customize the look and feel of your buttons and provide visual feedback to users when they’re clicked. We hope you found this article helpful, and happy coding!
