Using the Canvas widget, we can create text, images, graphics, and visual content to add to the Canvas widget. If you need to configure the Canvas item dynamically, then tkinter provides itemconfig(**options) method. You can use this method to configure the properties and attributes of the Canvas items. For example, if we create a line inside the Canvas widget, we can configure its color or width using itemconfig() method.
# Import the required libraries from tkinter import * # Create an instance of tkinter frame or window win = Tk() # Set the size of the tkinter window win.geometry("700x350") # Define a function to delete the shape def on_click(): canvas.itemconfig(line, fill="green") # Create a canvas widget canvas = Canvas(win, width=500, height=300) canvas.pack() # Add a line in canvas widget line = canvas.create_line(100, 200, 200, 35, fill="yellow", width=5) # Create a button to delete the button Button(win, text="Update the Color", command=on_click).pack() win.mainloop()
If you run the above code, it will display a window with a button and a line on the canvas.
Now, click the button to change the color of the canvas item.
