How can I hide the image in Tkinter Python-CodePudding

I want to hide the image in Tkinter Python module. How can I do it?

For example:

from tkinter import *

root = Tk()
root.title("Example")
root.geometry("500x500")
root.resizable(0, 0)

def hide():
   # How can I hide the image?

canvas = Canvas(root, width=500, height=500)
canvas.pack()

image = PhotoImage(file='example.png')
img = canvas.create_image(0, 0, anchor=NW, image=image)

hide = Button(root, text="Hide", command=hide)
hide = canvas.create_window(0, 30, anchor=NW, window=hide)

root.mainloop()

I try the [image].destory(), but it's not working.

To hide the image in Tkinter, you can use the itemconfig method to change the state of the image to HIDDEN. You can then use a button with a command callback to toggle the visibility of the image.

Here is an example of how you can modify your code to hide the image:

from tkinter import *

root = Tk()
root.title("Example")
root.geometry("500x500")
root.resizable(0, 0)

# Initialize a boolean variable to keep track of the image visibility
image_visible = True

def hide():
    global image_visible
    # Toggle the image visibility
    image_visible = not image_visible
    # Use itemconfig to change the state of the image
    canvas.itemconfig(img, state=NORMAL if image_visible else HIDDEN)

canvas = Canvas(root, width=500, height=500)
canvas.pack()

image = PhotoImage(file='physics_image.jpg')
img = canvas.create_image(0, 0, anchor=NW, image=image)

hide = Button(root, text="Hide", command=hide)
hide = canvas.create_window(0, 30, anchor=NW, window=hide)

root.mainloop()

The destroy() method is used to destroy a widget and remove it from the parent widget. However, it will not hide the widget - it will completely remove it from the window and free up the resources used by the widget.

If you want to remove a canvas object from a canvas, you can use the delete method of the canvas. It takes as a parameter the id of the object to be deleted:

canvas.delete(img)
