To reset the image on a button in tkinter, you can simply set the button's "image" attribute to the new image you want to display. First, create a new image using the PhotoImage class. Then, reassign this new image to the button's "image" attribute by calling the config method on the button object and passing in the new image. This will update the button's image to the new one you have created.

What is the safest way to reset the image on a button in tkinter?
The safest way to reset the image on a button in Tkinter is to first store the image as a variable, then configure the button with a new image or set it to None, and finally delete the previous image variable to free up memory.
Here's an example code snippet to demonstrate this process:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
import tkinter as tk def reset_image(button, image_var): button.config(image=None) del image_var root = tk.Tk() # Load image my_image = tk.PhotoImage(file='image.png') # Create button with image my_button = tk.Button(root, image=my_image) my_button.pack() # Reset image on button reset_image(my_button, my_image) root.mainloop() |
In this code snippet, the reset_image function takes the button and image variable as arguments. It first sets the button's image to None, and then deletes the image variable to ensure it is properly cleaned up. This approach helps to avoid any memory leaks or unexpected behavior when resetting the image on a button in Tkinter.
What is the recommended procedure for resetting the image on a button in tkinter?
To reset the image on a button in tkinter, you can follow these steps:
- Create a global variable to store the reference of the original image you want to reset to.
- When setting the image on the button for the first time, save a reference to the image to the global variable.
- To reset the image on the button, simply configure the button to use the original image reference.
Here is an example code snippet demonstrating the recommended procedure for resetting the image on a button in tkinter:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
import tkinter as tk root = tk.Tk() def set_image(): global original_image original_image = tk.PhotoImage(file="image.png") button.config(image=original_image) def reset_image(): button.config(image=original_image) button = tk.Button(root, text="Click me") button.pack() set_image_button = tk.Button(root, text="Set Image", command=set_image) set_image_button.pack() reset_image_button = tk.Button(root, text="Reset Image", command=reset_image) reset_image_button.pack() root.mainloop() |
In this example, the set_image function sets the image on the button using the original_image global variable. The reset_image function resets the image on the button by configuring the button to use the original_image reference.
How do I change the image on a button in tkinter back to default?
To change the image on a button in tkinter back to default, you can simply reconfigure the button with the default image. Here's an example code snippet:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
import tkinter as tk root = tk.Tk() default_image = tk.PhotoImage(file="default_image.png") new_image = tk.PhotoImage(file="new_image.png") def change_image(): button.config(image=new_image) button.config(command=change_back) def change_back(): button.config(image=default_image) button.config(command=change_image) button = tk.Button(root, image=default_image, command=change_image) button.pack() root.mainloop() |
In this code, we have defined two functions change_image() and change_back() which toggle the button image between default_image and new_image. When the button is clicked, it changes the image to new_image, and when clicked again, it changes back to default_image.
